Spoken as a true Luddite.
I couldn't disagree more. I think that this is a prescription for turning
off yet another generation to physics, and for continuing teaching
practices that appear to be inferior as judged by the literature.
A couple of standard references: "Learning motion concepts using
microcomputer based laboratory tools," Thornton and Sokoloff, AJP vol 58p
858do
"The effect of real time lab graphing on learning graphic representations
of distance and velocity," Brassel, JRST, vol 24, p 385ff.
These both showed that students doing kinematics experiments who had to
more traditional style analysis learned LESS than those who had real timeI'm not sure I can fully agree with this last paragraph. First, the
computer graphing tools. The physics is in the interpretation and
understanding of the graphs. Drawing graphs is important too, but it is a
separate skill.
