End of Year Business

 

Final Grades

All graded work for the 4th marking period should have been turned in by now, and so I’ll be updating Schooltool with grades for these assignments to finalize your 4th marking period grade. After this, you have a choice to receive a traditional numeric grade or a pass/fail grade. The default options are as follows:

  • Any student with a calculated final grade of 75 or higher will receive a numeric grade
  • Any student with a calculated final grade of 74 or less will receive a grade of pass/fail.

If you wish to change how your grade will be reported away from the default option, please email me, but also please report your preference by logging into Schooltool using the instructions found in this video, or as follows:

  1. Log into Schooltool
  2. Click on your name
  3. Click on the “User Defined” tab
  4. Click the green + sign next to IHS COVID-Closure Grading Options
  5. Go through your schedule, note the department, course, and grade option preference for each class period.
    1. If you don’t have a class during that period, select a grading choice of “N/A – No Class”
  6. Click the green SAVE button at the top of the section (next to IHS COVID-Closure Grading Options)
  7. If you want to edit your selections, click the white Edit button

See this FAQ for more information about the pass/fail option, or this document for more information about the end of the year procedures for students


Course Evaluation

I value your opinion on what I teach and how I teach it. It’s a tough job, and the transition to online distance learning made it especially challenging. I would deeply appreciate it if you would give me your thoughts on the course you took with me, both the in-person part and the online part. Please complete this evaluation. It’s a little lengthy, but there is a lot that I’m curious about and I hope you’ll be willing to send me your thoughts.

Your responses are completely anonymous, unless you choose to tell me your name. Please be honest and thorough!


Textbook, Calculator, Chromebook Returns

From IHS Administration: School materials (Chromebooks/charges for seniors only [underclassmen should keep their Chromebooks/chargers], calculators, library books, and textbooks) can be returned to the IHS Materials Recovery Station on Lake Street, outside the library entrance on the following dates:

  • Monday 6/15 from 4-6 pm
  • Wednesday 6/17 from 11 am to 6 pm

In addition to returning textbooks to the Lake St. Materials Recovery Site, for your
convenience, student textbooks and library books can be taken to the Tompkins
County Public Library (TCPL) for your convenience.

Please make sure all returned items are clearly labeled with the student and teacher’s name.


Final Thoughts

This has been a unique year, filled with challenges we never could have anticipated at its outset. Rarely does a single event have such a significant worldwide impact. This was uncharted territory, and I think we have all learned a lot about ourselves, about each other, and about how to be successful in a difficult time like this. I’ve recorded a short goodbye message for you all, which you can watch here.

 

Goodbye! I’ll miss you!

AP Statistics Assignment for 6/1

This Week’s Assignment

Due to the closure and the lost class time that involved, we were forced to skip the last unit of the course. Ms. Seifert and I have decided this content is still important for you to see, so we’re going to use the last two weeks of class to go back and discuss one more category of inference: the Chi-Square Test.

Ms. Seifert has created some more videos to watch, so please take the time to check them out here:

  1. Chi-Square Test for Goodness of Fit
  2. Chi-Square Test for Homogeneity
  3. Chi-Square Test for Independence
  4. (Optional): Stats Medic Summary of Chi-Square Tests

You may also want to check out the Desmos lesson we did in class on May 28th as a guided introduction to Goodness of Fit tests in particular. We didn’t get the chance to work on the second example (attached earlobes and tongue-rolling) together, but if you want to enter your responses and get some feedback, let me know and I can leave comments on your work. Make sure you sign in to your Google Account on Desmos, otherwise you won’t be able to access your responses again!

By Friday, June 5 at 2:00, please log into AP Classroom and take the Chi-square “Quiz” that is posted. The system should give you your score automatically after you complete the assignment, and if you have any questions about it, please sign up for Office Hours so we can chat!

This work is optional and not completing it will not impact your grade for the course.

Virtual Classroom Session

We’ll have our final virtual classroom session on Thursday the 4th at 10:00 am. Come by to say goodbye to your classmates and have a little fun! We’ll be going back to Zoom this time, and I’ll post the connection details Thursday morning.

AP Statistics Assignment for Week of 5/26

This Week’s Assignment

Watch these three videos:

  1. Two-Sample T-test Example 1
  2. Two-Sample T-test Example 2
  3. Matched Pairs T-test

Take notes as needed and revise your response to the ACT Investigate Task by Friday, May 29 at 2:00 pm. If you are just editing the existing Google Document that you have already submitted, you do not need to submit the document a second time. Otherwise, use the typical file naming guidelines

AP Exam Model Responses

AP exam questions have been released to teachers, but there are too many versions of the exam to write the model responses that I promised. Instead, if you’d like to review your responses with me, you can sign up for an Office Hours session and we can chat. For security reasons, I won’t be able to reveal the exact text of the questions you saw, but I’ll answer any questions you might have about your response to the best of my ability.

AP Statistics Assignment for Week of 5/19

UPDATE (5/21): I’ve uploaded a video of the final class conversation before the exam. I address some misconceptions about the test and answer student questions. Find it in the video archive here (password is our room number at IHS)

This Week’s Assignment

Study for your AP Exam on the 22nd! Read over CollegeBoard’s AP Statistics Test Guide and/or my version here.

Some resources:

What you need on Test Day

Practice Exams

Topical Review

  • IDENTIFY THE TEST: One thing I have noticed some students having difficulty with is identifying which test to use for a particular scenario. You can practice with this online game. Select the tests you want included in the mix and then click Submit, and you’ll be given a number of scenarios that you’ll be asked to identify the proper procedure before.
    • You should uncheck all three Chi-Square tests, the 1-Way ANOVA test, and the “Prediction Interval for a Single Value of y for a Fixed x”
  • OTHER STATS MEDIC UNITSI encourage you to review Units 1-4 in Stats Medic I do not currently have plans to assign any content from these units, but there is very useful review to be found there, and I’m happy to answer any questions you may have about that content. Just send me an email or sign up for an office hours session.
  • AP VIDEO STREAMS: The CollegeBoard YouTube page has a number of single-topic review videos in addition to the timed AP tests.
  • ONLINE MATH PRACTICEAll AP Statistics students have been granted access to IXL, an online math practice tool. There are skill practice modules for math content all the way from Kindergarten through Calculus, and there’s even some decent AP Statistics content. You will have to log in via Clever (instructions are here), click the IXL button on the page that loads, and then navigate to the Pre Calculus section. Any of the modules in sections X: Probability, Y: Probability Distributions, or Z: Statistics would be worthwhile practice for you!

Virtual Class Time and Office Hours

I’ll be running two virtual class sessions this week, both on Google Meet

  • Tuesday, 5/19 at 1:00 to 2:00pm
  • Thursday, 5/21 at 10:00 to 11:00am

In additional, I have several Office Hour sessions planned. Please sign up or drop in.


After the Exam

We will be doing two things.

  1. I want us to go back to t-tests (chapters 22-24 of your textbook) and review some of the smaller details that Stats Medic left off. After this redo, I want you to resubmit your ACT Investigative Task
  2. We skipped Chi-Squared tests, which some of you may already have some familiarity with from AP Biology. It’s an important topic, worth looking at.

COVID-19 CLOSURE WEEK 10 – LAST DAY OF INSTRUCTION FRIDAY, JUNE 5

On Friday, May 15, Governor Cuomo announced that five regions would enter “Phase One” of the reopening process. These regions include both the Finger Lakes and Southern Tier regions, meaning Tompkins County and all neighboring counties have begun  the re-opening process. See this page for more details about what Phase One looks like.

Unfortunately, all NYS schools will remain closed for the remainder of the academic year. At Ithaca High School, the last day of instruction will be Friday, June 5. While some assignments may be due after that date, teachers are being instructed to not assign any additional work after June 5.

All students will be given the option for each course to take a “pass/fail” grade for any courses they are currently taking, instead of the traditional numeric grade. See this FAQ for more information. I’ll calculate an estimated grade during the week of June 8 so that you can better make this decision. Keep an eye on your Schooltool account. That is my primary means of communicating to you about your grades!

We are still figuring out some of the further details for what the end of the year looks like. Keep an eye on this page or your email for more information.

Important/Useful links:

COVID-19 CLOSURE WEEK 9 – LAST CLASS DAY JUNE 5

On Friday, May 1, Governor Cuomo announced that all NYS schools, including K-12 and colleges, will remain closed for the rest of the academic year.

The last day of classes at IHS will be Friday, June 5. Some work may be due after that date, but no new content will be assigned on that day. After June 5, you’ll be given an option to take a grade for the course of “pass/fail” or a traditional numeric grade. See this FAQ for more information.

AP Statistics Assignment for Week of 5/12

This week’s assignment

We have another practice exam for you this week. Please complete it by next Tuesday, the 19th.

  • Click Here for Practice Exam Question 1
    • Give yourself 30 minutes to complete this question (25 to write your response, 5 minutes to upload it)
    • Decide on a submission option from the test guide page to practice using (maybe try a different one than you used last time, to see how well that goes for you).
  • Click Here for Practice Exam Question 2
    • Give yourself 20 minutes to complete this question (15 to write your response, 5 minutes to upload it)
    • Decide on a submission option from the test guide page to practice using. Try using the same one as Question 1, or experiment with a different option.
  • I will score your response according to a rubric. Your grade will be based on your completion (10 points in SchoolTool)
  • Please plan on completing these by Tuesday, 5/19 at 2:00 pm

Last Week’s Assignment

I’ll be sending out some general feedback about your responses to the practice AP exam questions posted last week. In the meantime, you can review some model solutions here:

A quick note about the Investigative Tasks you turned in last week: Ms. Seifert and I want to give you another chance at completing this assignment. We realized too late that the videos on StatsMedic, while thorough and sufficient for the AP exam, skip over some of the finer, smaller details the AP ignores that we feel are still important. We’re going to prepare some additional videos to review from so that you can optionally resubmit your investigative task response before we give it a formal grade. Stay tuned for that!


Thursday Virtual Class Time

We will have our usual virtual class session on Thursday, May 14 at 10:00. We’ll be using Google Meet this time. Link: https://meet.google.com/rhp-awup-yuy

Update (5/14): If you missed the meeting but would still like to work on the practice exam, you can find it posted here. My model solution is here, and I’ve posted a video of my debrief and a discussion here (the password is my classroom number at IHS!)

Based on the results of the Google Poll I sent out over the weekend, you want to use our last two sessions for 1) Live timed practice AP questions with discussions afterwards and 2) Prepared lectures on review topics. This then will be our plan for this session and the one on the 21st.

If you have questions about review, about a practice AP, or about anything from the year, please sign up for Office Hours


Office Hours

The results of the weekend’s check-in poll also indicated that you would prefer a combination of appointments and open drop-in time for office hours, with a heavier preference towards the latter. Please review the schedule posted here to sign up for a session.

Drop-in Hours:

  • Wednesday from 10:00 am to noon and from 2:00 pm to 4:00 pm
  • Friday from 10:00 am to noon

Official Scheduled Hours: 

  • Thursday from 11:00 am to 12:15 pm
  • Friday from 2:00 pm to 5:00 pm

I may be available at other times this week as well. Let me know when you’d like to meet!


Additional AP Review

At this point, I am expecting you to take charge of your own review for this exam. Here are some options:

  • OTHER STATS MEDIC UNITS: I encourage you to review Units 1-4 in Stats Medic as well. I do not currently have plans to assign any content from these units, but there is very useful review to be found there, and I’m happy to answer any questions you may have about that content. Just send me an email or sign up for an office hours session.
  • AP VIDEO STREAMS: There is a big archive of videos on the AP Statistics YouTube page. Live streams end this week, but there is some excellent review content there.
  • AP CLASSROOM: You have access to a number of free response questions in your AP Classroom account. They are marked with a small green bulls-eye image. They are not necessarily written to mirror what this year’s exam would look like, but the content they cover would be very useful to review.
  • ONLINE MATH PRACTICE: All AP Statistics students have been granted access to IXL, an online math practice tool. There are skill practice modules for math content all the way from Kindergarten through Calculus, and there’s even some decent AP Statistics content. You will have to log in via Clever (instructions are here), click the IXL button on the page that loads, and then navigate to the Pre Calculus section. Any of the modules in sections X: Probability, Y: Probability Distributions, or Z: Statistics would be worthwhile practice for you!
  • BARRON’S REVIEW BOOK: I have decided not to formally use the Barron’s review book I recommended you purchase earlier this year. The book is written for a more traditional exam, so much of it likely won’t be relevant to this year’s test. If you did get the book, the content in Topics 1-12 covers everything that may appear on this year’s test.

AP Statistics Assignment for Week of 5/5

Update (5/7): I’ve posted a copy of the sample problem we did in Thursday’s live virtual classroom, as well as my solution, a sample rubric for the problem, and a video discussion. Find them in the “Thursday Virtual Classroom” section below


As you are aware by now, schools have been shut down for the remainder of the school year. This means that the remainder of our review will be at a distance, as well any work we do post-AP exam (we’ll worry about that later).

Be sure to familiarize yourself with the AP Statistics Exam Test Guide. Take the time to check out the Demo AP exam linked there to familiarize yourself with what the platform will look like.

We will be spending these last three weeks before the exam reviewing, primarily by doing practice AP exam questions with each other. I strongly recommend you take advantage of the timed FRQ questions on the AP Statistics YouTube page starting here.


This week’s assignment

We are going to do a practice run of the AP exam ourselves. Ms. Seifert and I have prepared two Google Forms with questions similar to what you might expect on the AP exam. I recommend you do them all in one sitting, but you can break them up if you wish.

  • Click Here for Practice Exam Question 1
    • Give yourself 30 minutes to complete this question (25 to write your response, 5 minutes to upload it)
    • Decide on a submission option from the test guide page to practice using.
  • Click Here for Practice Exam Question 2
    • Give yourself 20 minutes to complete this question (15 to write your response, 5 minutes to upload it)
    • Decide on a submission option from the test guide page to practice using. Try using the same one as Question 1, or experiment with a different option.
  • I will score your response according to a rubric. Your grade will be based on your completion (10 points in SchoolTool)
  • Please plan on completing these by Monday, 5/11 at 2:00 pm

Thursday Virtual Classroom

We will meet on Zoom at 10:00 on Thursday, May 7th as usual. We’ll do a live timed AP review question there as well, review the scoring for it, then answer any questions you may have about the exam. I will attempt to record that second portion.

From today’s class:


Additional Review

At this point, I am expecting you to take charge of your own review for this exam. Here are some options:

  • OTHER STATS MEDIC UNITS: I encourage you to review Units 1-4 in Stats Medic as well. I do not currently have plans to assign any content from these units, but there is very useful review to be found there, and I’m happy to answer any questions you may have about that content.

– SCHOOLS CLOSED FOR REMAINDER OF YEAR

On Friday, May 1, Governor Cuomo announced that all NYS schools, including K-12 and colleges, will remain closed for the rest of the academic year. I am heart-broken that I will never be able to see you all together again in my classroom, but I understand that this is the right decision given the large amount of uncertainty that still remains about the spread of the virus. I appreciate and acknowledge all of the hard work you all are putting into all of your classes, and I hope that you can keep that momentum going through the end of the year.

It remains to be seen exactly what this means for instruction at IHS. Originally, our academic calendar was scheduled to end classes on June 16, before Regents exams. With the cancellation of June (and August) Regents exams, it is unclear when exactly instruction will end. Please keep an eye on the ICSD Coronavirus page for more developments.

One decision that IHS has made is that, come the end of the year, all students will be given an option to take a “pass/fail” grade for any courses they are currently taking, instead of the traditional numeric grade. See this FAQ for more information.

AP Statistics Assignment for Week of 4/27

UPDATE (4/29): The deadline for your task response has been changed. Your work is now due on Monday, 5/4 at 2:00 pm


UPDATE (4/28): When you are writing your response, please use an equation editor to create any formulas that you are referring to. There are several options, but I recommend an add-on called MathType. Instructions for installing and use can be found in this short video.


At this point, we have finished all new content and you’ve had opportunities to put much of what you’ve learned into practice. This week, you’ll do so again with a graded Investigative Task assignment.

Your assignment this week is simple: Complete the Chapter 22-24 Investigative Task by Monday 5/4 at 2:00 pm. This task asks you to analyze and draw conclusions about ACT scores for a group of students, and first part of this task involves gathering a sample of students. Find the full roster of scores here: ACT Task Data.

Recall the usual submission guidelines: Your response should be completed in a Google Document and submitted to me (bkirk@icsd.k12.ny.us) by 2:00 on Friday. Please name your file appropriately; it should have the format “LastName.FirstName.Ch22-24InvTask”.  For example, mine would be Kirk.Benjamin.Ch22-24InvTask”. When you are writing your response, please use an equation editor to create any formulas that you are referring to. There are several options, but I recommend an add-on called MathType. Instructions for installing and use can be found in this short video.

  • Questions about Investigate Task
  • Information about AP Stats exam

Ongoing additional work

  • PREVIOUS ASSIGNMENTS: Find past assignments by clicking the AP Statistics Assignment link above. I’m not checking in on these assignments as often any more, so if you do complete them now and you want me to take a look, send me an email and let me know.
  • AP VIDEO STREAMS: I highly recommend you watch the Statistics AP Live! videos run on YouTube every day from 2:00 to 2:45 pm (see this page for the full schedule for all courses). This week’s topics: Understanding the AP exam.
  • OTHER STATS MEDIC UNITS: I encourage you to review Units 1-4 in Stats Medic as well.

The majority of you stated you plan to take whatever test CollegeBoard puts together, and the rest said you’d wait and see what they come up with for their plan.

AP Statistics Assignment for Week of 4/21

This week, we’re going to try and finish the last bit of curriculum needed to start reviewing in earnest for the AP exam. The last topic is the remaining significance tests: The One-Sample T-Test, Two-Sample T-Test, and Matched Pairs T-Test.

Complete by Thursday at 10:00 am

  • Required: Watch Videos 7.1, 7.2, and 7.3 in Unit 7: Significance Tests on Stats Medic.
    • Optional: Watch videos 7.4, 7.5, and 7.6. The first two videos cover forms of statistical inference that have been omitted from the AP exam, and so we will be skipping those. Video 7.6 is some more about Type I/II errors and Power. You’re welcome to watch it.
    • Please click the red “Complete Step” button
  • Required: Read the notes that I have left with each video (click theNotes Icon (Stats Medic)icon) for additional information, answers to anticipated questions, and tips about using the calculator
  • Optional: Ask a question, answer somebody else’s question, or answer one of my “discussion question” prompts
  • Optional: Finish reading Chapter 22 (pages 586-597 about the One Sample t-Test) and Chapter 23 (pages 614-624 about the Two Sample t-Test), as well as Chapter 24 (pages 634-648, about the Matched Pairs t-Test and Interval). Work on some of the odd numbered exercises in each chapter and check your answers in the back of the book.
    • I highly recommend reading through Chapter 24, since the Stats Medic videos are a little light on this topic
  • Optional: Watch the Hypothesis Tests for Means video from CollegeBoard’s live AP Statistics streams.
  • Optional (strongly recommended): Complete 2015 Free Response Question #4 (as posted in Stats Medic) and score it using the video
    • This question is from the actual AP exam in 2017, and is similar to what you could expect to see on our exam this year. I very strongly recommend you write an answer as thoroughly as you would if it appeared on the actual exam, then score yourself using the rubric video. You can expect that your AP exam questions will be scored in a similar way.
    • If you do work on it, spend no more than 15 minutes completing it. Time yourself!
  • Required: Complete the Unit 7 Practice Multiple Choice in Stats Medic
    • You may skip questions 6, 7, 10, 16, and 17. You’re welcome to try them, but they deal primarily with the Chi-Squared and Regression inference procedures that we are omitting this year.
    • Your grade for this will be based on your completion, not your correctness.

 

Office Hours

In addition to our regularly scheduled Zoom meeting on Thursday at 10 (see below), I have set aside some time where I will be available for anybody who wants to drop in and talk:

  • Questions about 1-sample t-tests, 2-sample t-tests, and/or matched pairs t-tests
  • Questions about Unit 7 Practice Multiple Choice Questions
  • Collaborative work on Unit 7 Practice Free Response Question + Scoring

After Thursday Zoom Meeting, due by Monday, April 27 at 2:00 pm

  • Required: Complete the Unit 7 Practice Free Response Question in Stats Medic
    • If you attend the Thursday Zoom Meeting, my plan is to start this together.
    • You can write out your answers on a separate piece of paper, take a picture of it, and email to me.
    • Or, you can type out your response in a Google document and share it with me when you’re done.
  • Required: Log into AP Classroom and complete the Unit 7 Progress Check MCQ Part B and Unit 7 Progress Check MCQ Part C
    • Your grade for this will be based on your completion, not your correctness.
    • I’ve unlocked all Progress Checks for both Units 6 and 7. You’re welcome to try any/all of them.
    • Be aware that Unit 6 and Unit 7 of AP Classroom lines up closer with Units 5 and 6 of our textbook than with Units 6 and 7 of Stats Medic.

Ongoing additional work

  • PREVIOUS ASSIGNMENTS: Find past assignments by clicking the AP Statistics Assignment link above. I’m not checking in on these assignments as often any more, so if you do complete them now and you want me to take a look, send me an email and let me know.
  • AP VIDEO STREAMS: I highly recommend you watch the Statistics AP Live! videos run on YouTube every day from 2:00 to 2:45 pm (see this page for the full schedule for all courses). This week’s topics: Probability.
  • OTHER STATS MEDIC UNITS: I encourage you to review Units 1-4 in Stats Medic as well. I do not currently have plans to assign any content from these units, but there is very useful review to be found there, and I’m happy to answer any questions you may have about that content. Just send me an email!
  • ONLINE MATH PRACTICE: All AP Statistics students have been granted access to IXL, an online math practice tool. There are skill practice modules for math content all the way from Kindergarten through Calculus, and there’s even some decent AP Statistics content. You will have to log in via Clever (instructions are here), click the IXL button on the page that loads, and then navigate to the Pre Calculus section. Any of the modules in sections X: Probability, Y: Probability Distributions, or Z: Statistics would be worthwhile practice for you!
  • EXAM UPDATES: Keep an eye on CollegeBoard’s Coronavirus page for AP courses for more information about how our (and all) exam will look. The majority of you stated you plan to take whatever test CollegeBoard puts together, and the rest said you’d wait and see what they come up with for their plan.

COVID-19 CLOSURE WEEK 7 – DISTRICT CLOSED UNTIL 5/15

Per Governor Cuomo’s latest executive order, schools will remain closed until May 15 at the earliest. Furthermore, he has ordered that all New York State residents are required to “wear masks or face coverings in public whenever social distancing is not possible” including “on a bus or subway, on a crowded sidewalk, or inside a grocery store.”

AP Statistics Assignment for Week of 4/13

Update (4/17): In addition to the Google Form Worksheet and Desmos activity listed below, please complete this updated poll about your preferences regarding Zoom vs Google Meet, as well as your thoughts about how Distance Learning 2.0 is going for this class.


Welcome to Distance Learning 2.0 for AP Statistics! We are going to spend the next two weeks learning about and practicing with statistical inference procedures (confidence intervals and hypothesis tests) for means, which is the last major content area potentially covered on the upcoming modified AP Statistics exam. I will be using Units 6 and 7 in Stats Medic as our primary source of initial information, which I will supplement with some additional videos and virtual classroom sessions (Thursdays at 10:00 am!)

In order to use our virtual class time most efficiently, I will expect that you have completed most of the following work BEFORE our virtual class time on Thursday.

Complete by Thursday at 10:00 am

  • Required: Watch Videos 6.1 and 6.2 in Unit 6: Confidence Intervals on Stats Medic.
  • Required: Read the notes that I have left with each video (click theNotes Icon (Stats Medic)icon) for additional information, answers to anticipated questions, and tips about using the calculator
    • In particular, watch the additional videos linked in the “Why is it called a t-interval” note
  • Optional: Ask a question, answer somebody else’s question, or answer one of my “discussion question” prompts
  • Optional: Read pages 574-586 and 605-613 in your text. These sections cover more of the background about the t-distribution and the assumptions/conditions and procedure of the 1-sample t-interval and 2-sample t-interval
  • Optional: Watch the Confidence Intervals for Means video from CollegeBoard’s live AP Statistics streams.
  • Optional (strongly recommended): Complete 2017 Free Response Question #2 and score it using the video
    • This question is from the actual AP exam in 2017, and is similar to what you could expect to see on our exam this year. I very strongly recommend you write an answer as thoroughly as you would if it appeared on the actual exam, then score yourself using the rubric video. You can expect that your AP exam questions will be scored in a similar way.
    • If you do work on it, spend no more than 15 minutes completing it. Time yourself!
  • Required: Complete the Unit 6 Practice Multiple Choice in Stats Medic

ALL WEEK

  • Ask questions! I will be available to answer questions by email or phone phone/virtual meeting. All you have to do is email me with questions, or to set up a time to meet.

Thursday Zoom Meeting

On Thursday, 4/16 at 10:00 am, I will host a virtual classroom, again using Zoom (click here for the Chrome app if you’re using your Chromebooks, otherwise I recommend the downloaded version). I’ll post the link to join here and send it out by email when that goes live. I will be starting precisely at 10:00, so log in early! Come by and say hello and ask some questions. I look forward to seeing you!

Planned agenda:

  • Welcome/check in
  • Questions about 1-sample t-interval and/or 2-sample t-interval (or about the t-distribution in general)
  • Questions about Unit 6 Practice Multiple Choice Questions
  • Collaborative work on Unit 6 Practice Free Response Question + Scoring

After Thursday Zoom Meeting, due by Monday, April 20 at 2:00 pm

COVID-19 Closure Week 5 – Distance Learning 2.0 (Regents Exams Cancelled)

Starting on April 13th, the Ithaca City School District has moved to the next phase of our COVID-19 closure: Distance Learning 2.0. Click the link to go to the District’s comprehensive page for this new phase of our learning adventure.

You should have received two emails from Mr. Trumble or the IHS administration (if you missed then, you can find the 4/8 letter here, and the 4/10 letter here). From Mr. Trumble:

  • Starting on Monday April 13th, work assigned by teachers will be mandatory, graded, and will be used in order for our students to continue to earn course credit. 
  • While state Regents exams are cancelled in all subjects, students will need to successfully complete their course of study in order to be granted a waiver for the corresponding exam. Frequently asked questions can be found here
  • To maximize school-home communication we are strongly encouraging students to check their district email and Google Classroom at least once each day.  Details for each specific class will be available Google classroom (or equivalent). 
  • If students don’t understand the assignments or material, students are encouraged to reach out to their teacher for support during the posted office hours, email or additional communication pathway determined by the teacher.  Additional supports are offered through our student services department, our Deans of Students and our Academic Intervention staff.  

Details of what InCA and AP Statistics students should be doing now can be found in the relevant posts.

AP Statistics Assignment for week of 4/6

Update (4/8): ICSD has mostly finalized their plans for Distance Learning 2.0, and teachers are reviewing these guidelines and providing final feedback. You should start receiving some information about these plans very soon, if you haven’t already. Please check your email often for that information!

One of the changes for us is that our regular online sessions will be moving to Thursdays at 10:00 am. I have made a short form to explore your preferences about using Zoom vs. Google Meet; please complete it here.


As we prepare for ICSD’s Distance Learning 2.0, and our attempt to finish the remaining content necessary for our AP exam on May 22, I want to use this week to review Sampling Distributions. Your assignment is as follows:

This Week’s Assignment (my encouraged due date for all Required tasks is by 2:00 pm on Friday, April 10, however I am very flexible with this timing!)

  • Required: Sign up for a Stats Medic account by clicking this link (LINK REMOVED, CONTACT ME FOR REGISTRATION LINK). This will be a primary source of new learning and review for us going forward.
    • You do not need to download/print the notes that are listed, but taking notes while watching the videos would be a good idea.
  • Required: Watch Videos 5.1, 5.2, and 5.3 in Unit 5: Sampling Distributions from Stats Medic and leave an answer to at least one discussion prompt on any video
  • Optional: Watch this video (made by me) for a deeper dive into exactly what a sampling distribution is, and how it differs from a sampling distribution model. In the video, I use the simulation applications found here.
  • Optional (strongly recommended): Complete 2010 Free Response Question #2 and score it using the video
    • This question is from the actual AP exam in 2010, and is similar to what you could expect to see on our exam this year. I very strongly recommend you write an answer as thoroughly as you would if it appeared on the actual exam, then score yourself using the rubric video. You can expect that your AP exam questions will be scored in a similar way.
    • If you do work on it, spend no more than 15 minutes completing it. Time yourself!
  • Required: Complete the Unit 5 Practice Multiple Choice in Stats Medic
  • Required (unlocked on Wednesday): Complete the Unit 5 Practice Free Response Question in Stats Medic
    • You can write out your answers on a separate piece of paper, take a picture of it, and email to me.
    • Or, you can type out your response in a Google document and share it with me when you’re done.
  • Optional: Log into IXL (instructions can be found here) and complete the following practice modules to a score of 80+ (click these links after logging in, or search for the three-character code in the search bar at the top)

COVID-19 Closure Week 4 – ICSD Schools Closed through 4/29

Update (4/7): The NYS Department of Education has cancelled all June Regents exams. From their announcement (read the full version here):

Students who, during the June 2020 examination period would have taken one or more Regents examinations, will be exempted from passing the assessments in order to be issued a diploma.  To qualify for the exemption, students must meet one of the following eligibility requirements:

  • The student is currently enrolled in a course of study culminating in a Regents examination and will have earned credit in such course of study by the end of the 2019-20 school year; or
  • The student is in grade 7, is enrolled in a course of study culminating in a Regents examination and will have passed such course of study by the end of the 2019-20 school year; or
  • The student is currently enrolled in a course of study culminating in a Regents examination and has failed to earn credit by the end of the school year. Such student returns for summer instruction to make up the failed course and earn the course credit and is subsequently granted diploma credit in August 2020; or
  • The student was previously enrolled in the course of study leading to an applicable Regents examination, has achieved course credit, and has not yet passed the associated Regents examination but intended to take the test in June 2020 to achieve a passing score.

In other words:

  1. If you pass a current class with a required Regents exam at the end, you are exempt from the exam requirement for that class.
  2. If you do not pass a current class with a required Regents exam at the end, you must pass the class in summer 2020 to be exempt from the exam requirement for that class
  3. If you previously passed a class with a required Regents exam at the end, but did not pass the exam, you will be exempt from the exam requirement for that class if you intended to take the exam again in June 2020.

What does “intended to take the exam” look like? According to the FAQ document NYSED also released:

Schools can apply the “intended to take a Regents Examination” eligibility requirement under one of the following circumstances:

  • the student informed the school that s/he wished to retake the examination; or
  • the student was receiving academic intervention, supplemental instruction or
    tutoring of some kind in preparation to take the examination; or
  • the student took the examination in June 2019, August 2019, or January 2020 in
    an attempt to pass or better his/her score.

If you previously failed a required state Regents exam (but passed the class), and had already this year told your counselor you were planning to retake the test, or were in AIS to retake it, or had taken the exam in June 2019, August 2019, or January 2020, then you are exempt from the exam requirement.

If you have further questions about what this news might mean for you, reach out to your counselor. They are there to help!


On Monday, April 6th, NYS Governor Andrew Cuomo directed that the current closure of schools and non-essential businesses will extend until Wednesday, April 29

In Ithaca, working groups of teachers and staff from across the district are finalizing their recommendations for the ICSD Distance Learning 2.0 plan, which is expected to roll out on Monday, April 13.

AP Statistics Exam Test Guide (Updated 5/24)

Some Post-test updates from CollegeBoard:

I’ll be given access to your test questions and responses on Tuesday the 26th. I’ll plan to post my answers to the questions you tested on later that day or on Wednesday

If you requested a make-up test, you’ll be notified by email on Thursday May 28. The makeup exam schedule can be found here (ours is Thursday, June 4 at 4:00)


Update (5/17) From CollegeBoard:

We share the deep disappointment of students who were unable to submit responses.

  • Beginning Monday, May 18, and continuing through the makeup window, there will be a backup email submission process for browser-based exams.
  • This option will only be available for students who were not able to submit in the standard process—and they must then email their responses immediately following their exam.
  • These students will see instructions about how to email their response on the page that says, “We Did Not Receive Your Response.” The email address that appears on this page will be unique to each student.
  • Any student testing between May 18–22 who can’t successfully upload their response through the exam platform or send it to us by email, will need to request a makeup exam.
  • To protect the security and validity of exams, we’re unable to accept submissions from students who tested May 11–15. However, these students can feel confident that the email option will be in place for them during the makeup exams.
  • Email submissions will not be available for the World Language exams.

Start Here

  • Watch this video from CollegeBoard. It summarizes essentially everything you’ll need to know.
    • There’s good info in the other videos, too. Check them out.
    • Note that AP Statistics is a “Two Question” exam.
  • Download, print, and complete this Exam Day Checklist
    • I’ve added key information for the AP Statistics exam. You can find a blank version here for your other exams.
  • Download and print the AP Statistics Formula Sheet and Tables
    • This is mostly the same stuff as was on our formula sheet from class, but there are extra tables at the end that might prove useful.
  • Log into My AP and ensure your contact information is up to date.
  • Check out the Demo AP Exam and explore the submission options

 Test Taking Submission Options

  • Option 1: Copy/Paste and Submit
    • Your setup: Click the e-ticket in one window to access the test page and write your response in a Google Doc, Microsoft Word Document, or other word processor on another window (positioned side-by-side, ideally)
    • You answer by: Typing your response in the document
    • You submit by: Copying text into test window
    • Pros:
      • Typing is probably faster than handwriting
      • Easier to edit answers
    • Cons: 
    • Other things to remember: 
      • Make sure to include your 8-character AP ID and initials at the top of each file
      • Supported browsers: Chrome (recommended), Firefox, Safari, Microsoft Edge (but not Internet Explorer)
      • If you have the Grammerly add-on installed, you will need to remove it.
    • Bottom Line: This is probably the best option. Typing math is tricky, but I think the benefits outweigh the risks
  • Option 2: Attach typed text document and Submit
    • Your setup: Click the e-ticket in one window to access the test page  and write your response in a Google Doc, Microsoft Word Document, or other word processor on another window (positioned side-by-side, ideally)
    • You answer by: Typing your response in the document
    • You submit by: Saving a text file (a different file per question) and uploading it to the test window.
      • Supported text file formats: .doc, .docx, .pdf, .txt, .odt
    • Pros:
      • Typing is probably faster than handwriting
      • Easier to edit answers
    • Cons: 
    • Other things to remember: 
      • Make sure to include your 8-character AP ID and initials at the top of each file.
      • Create and pre-save your documents
      • Supported browsers: Chrome (recommended), Firefox, Safari, Microsoft Edge (but not Internet Explorer)
      • If you have the Grammerly add-on installed, you will need to remove it.
    • Bottom Line: No big difference over option 1. There’s a small risk of uploading the wrong file, but you can avoid this by pre-saving your documents and carefully naming them (e.g., LastName.FirstName.APQuestion1 and LastName.FirstName.APQuestion2)
  • Option 3: Attach photos of handwritten response and Submit
    • Your setup: Click the e-ticket on your cell phone or tablet and open the test page. Have pen/pencil and paper nearby to write your responses.
    • You answer by: Handwriting your response on lined or unlined paper
    • You submit by: Taking a picture of each page (up to 5 allowed) and uploading them to the test page.
    • Pros:
      • You’re already used to handwriting math responses
    • Cons: 
      • Response must be submitted as a picture (.png, .jpg, .jpeg) or scanned PDF
        • Note that if you upload a PDF, it must be submitted as a “text” file and not an “image” file
        • Many iPhones take pictures as HEIC files, which are not accepted. You can change this setting by going to Settings > Camera > Formats and selecting “Most Compatible”
      • Writing for such a focused length of time can be painful to your hand
      • Must scroll on phone to see questions
      • You’re not looking at the screen while working, so you might miss the timer alert
      • Harder to use cell phone as backup timer
      • Photo quality must be perfect
      • Runs the risk of accidentally submitting before uploading all images.
    • Other things to remember: 
      • Make sure to write your 8-character AP ID and initials on the top of each page (as well as a page number for multi-page submissions)
      • You’ll submit your images all at once. Don’t hit “Submit” until all have been uploaded!
    • Bottom Line: I don’t recommend this option. While handwriting math is likely easier than typing math, there are too many ways for this to go wrong.
  • Option 3 (alternative): Upload photos of handwritten response to computer and Submit
    • Your setup: Click the e-ticket on your computer to access the test page. Have pen/pencil and paper nearby to write your responses.
    • You answer by: Handwriting your response on lined or unlined paper
    • You submit by: Taking a picture of each page (up to 5 allowed) or a PDF scan of all pages, emailing/uploading them to your computer, then uploading them to the test page.
    • Pros:
      • Allows you to handwrite math while eliminating some of the disadvantages of accessing the test on your phone.
    • Cons:
      • Same issues with photo quality and requirement of image files (not pdfs)
      • Many steps make take time that you can’t afford.
      • CollegeBoard does not recommend this
    • Other things to remember: 
      • Make sure to write your 8-character AP ID and initials on the top of each page (as well as a page number for multi-page submissions)
      • You’ll submit your images all at once. Don’t hit “Submit” until all have been uploaded!
    • Bottom Line: CollegeBoard does not recommend this option and nor do I. The number of steps behind taking proper photos, uploading them to your computer, and submitting them gives you too little room for error.

What will Test Day Look Like?

  • Two days before the exam (May 20 for us), you’ll get an e-ticket in your email. You will use this ticket to access the exam on the 22nd.
    • This ticket will also be accessible on your My AP account
  • Click the link on your e-ticket no later than 1:30 pm on Friday, May 22nd. You’ll be asked some security questions, then be placed in a waiting room until 2:00
  • Immediately at 2:00, Question 1 will appear along with a timer for 30 minutes. You will have 25 minutes to write your response, then 5 minutes to upload it.
    • IF YOU DO NOT SUBMIT YOUR RESPONSE TO QUESTION 1 BEFORE THE TIMER EXPIRES, YOU WILL NOT BE ABLE TO SUBMIT IT AT ALL
  • After 30 minutes, Question 2 will appear along with a timer for 20 minutes. You will have 15 minutes to write your response, then 5 minutes to upload it.
  • From CollegeBoard: “Don’t worry if you don’t complete all parts of the question before you need to attach and submit your response. To give students as many different chances to demonstrate what they know as possible, a question may have more parts than can be answered in the allowed time. You don’t need to complete the entire question to get a score of 5, but you do need to submit whatever work you’ve done.”

Additional Information

  • The full 2020 AP Testing Guide can be found here. The guide is written for teachers, but students are welcome to review it as well.
  • If you have previously-approved testing accommodations, (e.g., extended time for tests) they will be automatically applied to the exam. More information can be found here.
    • If you experience a sudden temporary disability, e.g., you sprain your wrist the day before the exam, emergency accommodations can be made available. Contact Ms. Eva Collier, our school’s AP Coordinator, and/or visit the link above.
  • If you have a known conflict on May 22, you do not have to do anything. Do not click the link in your e-ticket on the 22nd, and a new ticket to access the makeup test on Thursday, June 4 at 4:00 pm will be automatically sent.
  • If you encounter a technical issue that you feel impacted your ability to perform effectively on the test, you may request a make-up exam.
    • Acceptable reasons for a request: sudden sickness, significant interruptions from family members, battery failures, power outages, or technical disruptions
    • Your request must be submitted here within 48 hours of the exam date.

I expect still more information will be made available as we move closer to test day. Watch this space, watch your email, and watch AP’s Coronavirus Page for more updates


Update (4/21): The IHS Administration has made some decisions about AP exams at IHS.

  • If you plan to take the test, you do not have to do anything. You are currently registered, and Ms. Collier, our school’s AP Coordinator, will submit your registration fee after the exam.
  • If you plan not to take the test, you also do not have to do anything. Just don’t log in on the day of the exam.
    • That said, I would appreciate you keeping me in the loop about your decision!
  • You may make the decision to not take the exam up to and including the day of the exam itself. Ms. Collier will look at the actual results of who takes and didn’t take the exam and will process registration fees accordingly. You will receive a full refund for any exams you did not take.

Update (4/15): I attended a webinar hosted by Trevor Packer last night and have a few small updates:

  • First a reminder:
    • Our exam is on Friday, May 22 at 2:00 pm. There is a makeup day of Thursday, June 4 at 4:00 pm, though CollegeBoard is saying this is “For students with Technical or Other Disruptions.”
  • On April 28, CollegeBoard plans to release more detailed information about the revised AP procedures, including instructions on what information you’ll need to have with you when you sit down for the exam. Trevor did give a little more information on what test day looks like:
    • On the 22nd, you’ll receive an email with a link to your exam page. This invitation will also appear in your online AP profile.
    • Plan on logging in no later than 1:45 pm. You’ll be asked some initial information to confirm your identity, then you’ll be placed on an online “waiting room.”
      • You will have until the start of the test to decide whether you want to hand write/upload your responses, or type/copy+paste your responses. It was unclear to me whether you can change your mind mid-test. I doubt this.
    • Exactly at 2:00, the first free response question will appear, along with a 30 minute timer. You will have the first 25 minutes to compose your answer. At the 5 minute mark, the timer will turn red and you will see a prompt to submit your response. Stop working at that point and submit your information. If your connection is slow and the submission does not finish by the end of the timer, that is okay. As long as you’ve initiated the submission process, it will continue in the background
    • Exactly at 2:30, you will lose all access to the first question, and a second free response question will appear, along with a 20 minute timer. You will have the first 25 minutes to compose your answer. At the 5 minute mark, the timer will turn red and you will see a prompt to submit your response. Stop working at that point and do so.
  • Here’s what I know about the questions themselves:
    • Both will be “multi-focus” in nature, meaning both questions will draw on your knowledge from two or more of the major aspects of the course:
      • Exploring Data
      • Sampling and Experimentation
      • Probability and Simulations
      • Inference
    • Both questions will be of similar difficulty to past free response questions, though the first question will be longer.
      • Trevor has said that you should not expect nor plan to finish either question, and that students will still be able to get a 5 even if they do not finish.
    • All required calculations can be done with paper and pencil, with no calculator (graphing, statistical software, etc.) required. However, use of a calculator is allowed and may be helpful (e.g., for completing basic arithmetic problems).
    • You may use the AP Statistics Formula Sheet. You may have this open as a page on your computer, or print it out to refer to. I do not know (though I doubt; see below) if you’ll need access to the tables included (standard normal table, t-distribution table).
  • SPECULATION ZONE – ALL INFORMATION HERE ARE MY OWN GUESSES ABOUT THE EXAM AND IS NOT CONFIRMED BY COLLEGEBOARD AT ALL
    • I don’t think there will be a full hypothesis test question, where you will write hypotheses, check conditions, complete the mechanics, and write a conclusion.
    • That said, I do think there will be parts of a hypothesis test question, e.g., here are some hypotheses, check the relevant conditions; now here are the mechanics, state the appropriate conclusion. Or: given a sample statistics and margin of error, write and interpret a confidence interval and use it to check a hypothesis.
    • I suspect there may (also? instead?) be a question asking you to test a hypothesis, and maybe even calculate a p-value, from the results of a simulation. Think about the “smelling Parkinson’s” example we did at the start of the class, or the simulation-based statistics you did in Algebra 2 (if you’ve already completed that class). Something like: “Given that 23 of these 1000 simulated trials produced a statistic as-or-more-extreme than the one observed, what can we conclude?”
    • There will almost definitely be a question asking something about the design of an experiment or survey, and it will probably be the former.

We’ll have more information about the test on Tuesday, the 28th.


On Friday, April 3, Collegeboard released a new Coronavirus page with updates on how the AP examination process will change due to nationwide school closures. I recommend that students carefully read everything in the Students section of this page (as well as the FAQs), but I’ve tried to compile some of the highlights for our class below:

  • The new exam date is Friday, May 22 at 2:00 pm
    • If school has reopened by this time, you’ll be taking the exam in school. Otherwise, you’ll be taking the exam at home.
    • An alternative late test date of Friday, June 5 at 4:00 pm is available for those with a school-approved conflict on May 22
  • The exam will be open book/open notes
    • Specifically, you are permitted the following notes, resources, and tools:
      • Class notes created by the student
      • Classroom resources provided by the teacher
      • Previous assignments or assessments returned by the teacher
      • Calculators for certain exams (see specific exam information for details)
      • Your AP Statistics Formula Sheet
    • You are permitted to store/access these resources digitally
    • You may not:
      • Communicate with any other person during the exam through any means, including online, in-person, by mobile or other device
      • Crowdsource support from group messages, online forums or social media
      • Incorporate the work of another person or technological service into their own exam response, including language translation
    • Collegeboard has posted some open book/open notes exam tips. I suggest you take a look at them and pay attention to what they say.
  • The exam will feature two free response questions
    • You will have 25 minutes to read and response to Question 1, and then 5 minutes to upload your response. Your score for Question 1 will be worth 55% of your exam score
    • You will then have 15 minutes to read and response to Question 2, and another 5 minutes to upload your response. Your score for Question 2 will be worth 45% of your exam score.
    • Once your response to Question 1 has been submitted, you will not be able to return to it.
    • Both questions may cover two or more of the central topics to the AP Statistics course:
      • Exploring Data
      • Sampling and Experimentation
      • Probability and Simulations
      • Inference
    • Free response questions 1-5 from past exams will be good models for the questions that will appear on this year’s exam. There will be no Investigative Task question (question 6 from past exams).
  • You can take the test/submit answers on a computer/laptop, or on a smartphone
    • When on a computer/laptop, you can type your answers or handwrite them, then upload/submit a photo
    • When on a smartphone, you can handwrite your answers and take a picture/upload them from your phone.
    • Collegeboard recommends you pick one of these strategies, and not try to juggle both.
    • There will be video demonstrations and live “simulations” so you can experiment with these methods of test-taking and response submission posted in late April.
    • If you don’t have a device, please let me know ASAP, and complete Collegeboard’s access form here.
  • Collegeboard will be taking exam security very seriously, possibly even moreso this year than in the past. Read more about their plans here.
  • All teachers will be given access to student responses by May 26.
    • This will partially serve as another step for exam security, but will also allow us to use your responses in our calculation of a grade for the course.
    • I will post an update on if/how Ms. Seifert and I plan to use this information later, once we have made this decision.

I expect Collegeboard will continue to release information about this exam and its contents in the coming weeks. They are continuing to release daily live instructional videos for all of their exams, and you can access that schedule here. I recommend that you watch these videos to supplement the work we are doing in class.

AP Statistics Assignment for Week of 3/30

Update (4/3): I’ve made a short video debrief of this week’s Designing Experiments Desmos activity, highlighting common answers and common errors I saw in your responses. You can find it here.

Also, Collegeboard has release a bunch of new information about the exam, which I’ve summarized here.


Update (4/2): As we move towards the district’s Distance Learning 2.0, I want to shift our focus a bit to another platform: Stats Medic. They have a very well-made AP Statistics review course that I plan to use extensively in these next few weeks. Click the link above, make an account, and start checking things out. You can work through the course in order, but I especially recommend you take a look at Unit 5: Sampling Distributions.


Among the higher-voted requests on my Review Priorities Google Poll was Designing Experiments, and so that’s what I’ve selected to focus on for this week.

  • Watch this video for a recap of this content from Chapter 13 (if you want)
  • Please log into and complete this Desmos lesson here (Desmos room code WYC9CZ).
    • Make sure you hit the “Log In with Google” button.
    • Based on your feedback, I have hit the “Anonymize” button so that there is less pressure for what you enter.
    • Please check back again a day or so after you submit your answers so you can see my feedback!

After you complete the Desmos activity, please log into AP Classroom and complete the “Designing Experiments Quiz” by Thursday April 2 at 3:00 pm. I’ll send you a score, but of course the score will not count towards or against your grade for this course.

If you have questions, post them here or send me an email. On Wednesday, 4/1 at 11:00 am (note the time change), I will host another virtual get-together, probably using Zoom this time (click here for the Chrome app if you’re using your Chromebooks, otherwise I recommend the downloaded version). I’ll post the link to join here and send it out by email when that goes live. Come by and say hello, ask some questions, or just chat. I look forward to seeing you!


Ongoing additional work

  • AP VIDEO STREAMS: I highly recommend you watch the Statistics AP Live! videos run on YouTube every day from 2:00 to 2:45 pm (see this page for the full schedule for all courses). The first several videos are meant to finish the content of the course that we likely will never get to given the ongoing closure. While you will not be tested on this content, it is still useful and important stuff (especially the Chi-Squared videos!)
  • ONLINE MATH PRACTICE: All AP Statistics students have been granted access to IXL, an online math practice tool. There are skill practice modules for math content all the way from Kindergarten through Calculus, and there’s even some decent AP Statistics content. You will have to log in via Clever (instructions are here), click the IXL button on the page that loads, and then navigate to the Pre Calculus section. Any of the modules in sections X: Probability, Y: Probability Distributions, or Z: Statistics would be worthwhile practice for you!
  • EXAM UPDATES: Check back at the Collegeboard’s Coronavirus page for AP courses on Friday, April 3rd for more specific information about how our (and all) exam will look. The majority of you stated you plan to take whatever test Collegeboard puts together, and the rest said you’d wait and see what they come up with for their plan.

COVID-19 Closure Updates (Week 3): All ICSD Schools Closed Through 4/15

Update (4/1): From the most recent communication from Superintendent Dr. Brown:

Lastly, Governor Andrew Cuomo’s recent Executive Order requires all school districts to continue distance learning and meals through the previously scheduled spring break. During that period of time (April 6 -10) we will continue with the system already in place. No additional duties will be necessary as we maintain the current instructional delivery.

In effect, this means that spring break is canceled. I will be posting another assignment next week similar to the assignments you have seen these last two weeks.


A message from ICSD Superintendent Dr. Brown:

Greetings, ICSD Community,

As our world grapples with the challenges due to COVID-19, I am reminded of the strength and culture of love present in our community. I am humbled and honored to craft our new path forward together. Thanks to all who have shared their time, perspectives, and expertise as our school district moves forward without students being physically present in our buildings.

Today, New York State Governor Andrew Cuomo announced that schools in New York State will be closed through April 15, 2020. Many in our community are watching the news and the national conversation about what may be next as our state and country respond to the pandemic.

Please know that the Ithaca City School District (ICSD) educators are actively planning for the possibility of school closures that extend beyond April 15th. ICSD teachers, aides and teaching assistants, and administrators collaboratively designed our current plan, and we are now forming working groups to specifically design the what and how of the next phase of distance learning. This next phase, or ICSD Distance Learning 2.0, would include much more student/teacher interactions, along with more direct instruction provided by our educators. For our younger learners (grades 2-5), this enhanced teaching and learning approach would include the distribution of mobile devices and internet access. We will keep our entire community apprised of developments in this area, and we continue to partner with school district and union leadership, as well as community partners.

 While continuously improving our instructional delivery, we are at the same time providing food services to many young people in our community. We are currently delivering approximately 2700 meals each weekday. Thanks to all who are responsible for making this extraordinary feat possible. Our new order form allows us to offer different menu options and attend to allergy needs and preferences. Folks can also order by dialing 2-1-1. Please order before noon on Sundays to receive meals beginning on Monday of that particular week.

Additionally, if students or families are experiencing issues with technology (how to log on, device not working, missing charger, etc.), please call the Family and Student Technology Support Line any time at (607) 882-9850. Please leave a voicemail and someone will call you back as soon as possible.

We are thinking of those in our community who have been coping with sickness; we wish folks health as quickly as possible and thank those who are caring for them. As I’ve noted in other communications, we must partner in unprecedented ways to navigate the current unprecedented challenges.

Regards,

Luvelle Brown Ed.D.
Superintendent
