Days 112-114: Tri 2 Reflections

This was a strange week. Monday we had regular classes, Tuesday we had a professional development day since several of our schools were used for primary elections, then Wednesday and Thursday were final exams. Physics did a traditional written test, followed by a lab practical and AP Physics took a practice exam. While students took those exams, I took some time to reflect on the year so far.

This trimester, I’ve had a lot of students working on other things during class. I think part of the issue is I’ve been doing less whole-class discussion on problems this year, which has lead to less sense of collective responsibility. Going in to trimester 3, I need to think about how I can do a better job of making it clear that everyone has something they can contribute and everyone should contribute.

I made some changes to my circuits unit this year. In the past, I’ve relied almost entirely on PhET’s circuit construction kit. This year, in response to some findings in my PhD research so far, I combined the simulation with some real world labs, which paid off with my students feeling more confident and having higher achievement. I tend to rely heavily on Pivot Interactives for circular motion and rotation, which we’ll be starting right after spring break, but I need to make sure I’m connecting those computer-based labs to things my students can touch and manipulate directly.


One of the things I’ve done this trimester that’s had the biggest impact on whole-class discussions has been giving students time in small groups to have preliminary discussions for most class discussions. I’ve done that prior to board meetings for a while, but doing that before problems, as well, has made students much more comfortable speaking up. That time also needs to be explicit; if I don’t set aside specific time for preliminary discussions, most students won’t initiate those discussions in their groups. Especially at the start of the trimester when some of the students are new to me, I need to make sure I continue to give students that time.
