It seems we have collectively addressed this topic every six or eight months/snip/
for as long as I've been a part of phys-l--and that means 12 or 14 years.
I want to raise some larger issues before this discussion goes too far.
1. This topic is well covered in the literature. There is very strong
evidence for the effectiveness of computer data collection; consult most
anything written in the last ten years by Sokoloff, Thornton, Laws, or
Beichner. Without considering educational experiments, we are only throwing
around opinions that are often not well founded.
1a. We must guard against what I like to call the
"My-opinion-is-better-than-your-research" dismissal of educational
experiments. This is a popular technique of both extreme conservatives and
extreme liberals.
Finally, remember that all absolute statements are false. ;-)
