Reflection: Qualitative Evaluations Reflection on Electrostatics - Section 3: Creating Idea Webs

 

At the beginning of this unit, I had my students create webs about the topic of 'electrostatics.' Today, they return to that topic with the benefit of several weeks of instruction and learning. Here are some thoughts comparing some of the early webs with a later one.

One aspect of this type of evidence of student learning that I find interesting is that some distinctions that teachers might make are often lost on students. In this example, the student has folded "net forces" and energy transformations into the idea of "electrostatics." Time-wise, she's absolutely correct - we did, indeed, fold those topics into this unit as I thought they'd be good entry points for some broad Physics ideas. But, conceptually, these ideas are not "underneath" the topic of electrostatics. While I don't think this conflation is much to worry about, it's a good reminder to me about how my choice of time and my connection between topics can get mirrored by my students' thinking.
