The physics is in the interpretation and
differencesunderstanding of the graphs. Drawing graphs is important too, but it is a
separate skill.
I must disagree here. There is a lot of good physics in analyzing the
free-fall spark tape witha meter stick and doing the successive
by hand. It really brings to life boring statements like delta X overdelta
T is the average velocity over an interval, in a hands on way (in thebest
tradition of hands on active style learning). Lot's of physics is inareas
other than interpreting and understanding the graphs!!
course has to do this as well, but since it is all automated this facttends
to be totally obscured in the CBL's I've seen. Just telling the studentsof
what the computer is doing doesn't cut the mustard as that is too passive
a learning situation in the laboratory.
