This week, both of my classes spent a lot of time working problems to practice translating between different representations of constant velocity. In Physics, velocity vs. time graphs seemed to either click immediately for students, or to be a big struggle. Usually, I have a lot more students with an experience somewhere in between. Regardless, by the end of the week even the students who found velocity vs. time graphs really challenging were getting the hang of them. In my AP Physics 1 class, most students seemed to be in a place where the velocity vs. time graphs were clicking pretty quickly.
AP Physics 1 also was able to do the dueling buggies lab practical. We had some great conversation about the sources of uncertainty in their predictions. Each group took a different approach, but got the same predictions for where the collision would happen, which is always fantastic. I’m also starting to see more of my students’ personalities in this class, which is making this class a lot of fun. AP is a lot smaller than my Physics classes, so I’m not surprised that is starting to feel like a cohesive class sooner than Physics.
This week, I also had a lot more conversations than usual with students who said they “aren’t a science person” or “aren’t good at science”. I suspect some of it is rooted in all the challenges of what science classes looked like last year, but that doesn’t make it any less important for me to address. I’ve been slow to start discussions of what skills groups needed to complete a task, but I need to make sure I’m making time for those. I also found myself telling students if their answers were right a lot more than usual in order to help them get some immediate confidence to keep them moving forward on problems, but the downside is it really limits the discussion students have once one of them knows they have the right answer. I need to figure out how I’m going to balance the need to keep the door open for student discussion with how I’m going to help students feel more confident in my classroom.
