AP Physics B End-of-Year Survey Results

Before I start planning for the new AP Physics 2 class in detail, I first reviewed the end-of-year feedback from my AP Physics B students. I made very few changes in this course last year since two years ago went well and this is the last year for the course. In the following charts, a “1” represents strongly agree and a “5” represents strongly disagree.

A majority of the students didn’t read the textbook much. I’m not surprised by this since I don’t push the textbook very much. It is dated and doesn’t align much with my pedagogy. Students rely on other resources from class much more. However, I do think it is important that students learn to read a college-level text. I’m extremely pleased that next year we will have Knight’s College Physics text which I will incorporate much more strongly into the new AP Physics 2 course.

I assigned conceptual questions from the textbook. Again, most students didn’t answer these. However, those that did, found them valuable. The conceptual questions assigned from the text were different than those I used for peer instruction. I may make use Knight’s conceptual questions as some of the peer instruction questions next year, which I expect will motivate students to answer them.

Many students did not solve the homework problems. Those that did, found them helpful. Honestly, with few exceptions, I’m fine with this. I don’t grade homework and want students to learn to determine if they need the additional practice or not. Most of my students learn to self assess and make good choices in this area.

Lab activities and practice quizzes are all about learning and not graded. Students found the quizzes (old AP free response questions) particularly useful. I’m really going to miss having a huge collection of old free response questions next year in AP Physics 2.

I wanted to highlight peer instruction specifically. I was surprised last year how valuable students found peer instruction focused on conceptual questions. This year’s feedback was just as strong. In the free-form comments in the section “What are some things that I should keep doing next year?” peer instruction was mentioned more than anything else. I think focusing on conceptual questions through peer instruction will be even more important in the new AP Physics 1/2 courses which emphasize a deep, conceptual understanding. Perhaps, since this has been a focus of my class for the past two years, is why I’m freaking out much less than other AP physics teachers after taking the AP practice exams.

Strong positive feedback on the summative labs for the course. I plan to incorporate those that are relevant into the AP Physics 2 course next year. We’ve already incorporated some of them into the AP Physics 1 course. The choices for the “I found the summative labs:” question ranged from too challenging (1) to too easy (5). In similar fashion to my AP Computer Science students’ feedback, students found the written feedback provided via Canvas helpful in developing their understanding of the material.

A couple of surprises in terms of which labs students marked as their favorites. The Simple Harmonic Motion lab has students develop a mathematical model by modifying various physical characteristics of a mass on a vertical spring. I was surprised it wasn’t more popular. We also did this lab in Honors Physics (AP Physics 1) this year. I was surprised that the diffraction and interference lab was in the top 5. I don’t feel that it is one of my strongest labs, yet students disagree. No surprise that the capstone project was the run-away favorite. I will keep that in the AP Physics 2 class. I’m planning to continue to do the CMS Masterclass, which focuses on particle physics, in AP Physics 2 as well. Hopefully, we can do this as part of a field trip to Fermilab next year. We didn’t have a field trip to Fermilab this year. The most common suggestion in the section “What are some things that I should try next year?” was to have a field trip to Fermilab. I hate to lose the Projectile Motion lab. The only way it would be part of AP Physics 2 is if I use it as a lab for an introductory unit on computational modeling. It is too advanced for AP Physics 1 in the projectile motion unit.

Pleased that so many students are considering pursuing STEM-related fields, but not too surprised since this is a second-year physics course.

Strong positive feedback on standards-based assessment and reporting. Summative labs and exams were scored on a 1-5 scale. Each unit that consisted of one exam and one lab. I’m considering changing this next year and having a standard for each AP Physics 2 Essential Knowledge item grouped into categories based on each AP Physics 2 Big Ideas. I feel this will emphasize science practices and connections between concepts rather than my traditional approach focused on units and content.

This summer I have a lot of work to do developing the new AP Physics 2 course which includes incorporating a new textbook and much more Modeling Instruction. I’ll take as much as possible from the AP Physics B course since most of it worked well the past two years. My AP Physics 2 students will also be piloting a 1:1 program (Chromebooks in the fall semester) which will require some additional preparation. AP Physics B is dead! Long live AP Physics 2!
