I'm going back and watching video we've collected from teachers' classrooms for evidence of PCK and attending to the disciplinary substance of student ideas. Thought this video was awfully cute:
This comes from a class that has been using an adapted version of the Physics by Inquiry electric circuits model. The groups are in the process of devising rules for what happens to the current through the battery when a bulb is added in series and (separately) when a bulb is added in parallel.
Not sure what all of the sound effects that Frank is using mean, but I think the circuit that he's 'tracing' with his 'motorcycle sounds' is a parallel one. I think the crash at the end might be when the 'current' returns to the battery.
