An e-mail from reader Kara Monroe:
I had a moment on the bike at the gym last night thinking of all the different questions student would naturally form just from looking at the display on a stationary bike.
I'm obliged to Kara and Alex for the inspiration here. A few remarks on Alex's video to preface my redesign:
- I'd like my students to look at the world and formulate their own mathematical questions. Therefore I'd like to show them as good of a facsimile of the world as digital video will allow. This means no artifice like a soundtrack or text on the screen. This also means I prefer fixing a camera to a tripod so the students aren't distracted by this third party holding the camera.
- Part of formulating and solving a question is deciding what information is important. So I removed the part where Alex tips them to the percent and the time elapsed: "Watch closely: 31:30 … 90% complete."
- I don't include this in my redesign (which I faked from elements of Alex's video) but you'd want to film the rest of the exercise session in order to show students the answer.
