Thinking about whiteboarding in physics classes - has anyone ever triedto
use an in class document camera connected to a datashow for small group
presentations back to a class.
Hypothetically setting up camera to capture and display an A3 area,
providing A3 paper and felt markers to a class. . . .
1) Note that there was recently a long-running discussion of whiteboarding
over on the PHYSLRNR-LIST.

2) As for the document-camera idea: That wouldn't be my first choice.
*) The low-tech time-honored way of preparing graphics is to draw on
8.5x11
acetate sheets ("foils"). To present to the group, use an overhead
projector.
This is how things are done in the real world ... and it works just fine
for
students.
-- I recommend the so-called "permanent" pens. That's because if you
use the water-based pens, you wind up with ink on your fingers and
fingerprints on your foils. You can make corrections to the so-called
permanent drawings using alcohol as a solvent, which is known to be not
particularly toxic in the quantities we are talking about ... in stark
contrast to the xylene and toluene they use for the whiteboard markers,
which I prefer to avoid.
