[Phys-L] Re: Whither Introductory Physics Labs? (was Lab Reports - was Human Error)

Generally students who do well can discuss and tell you what they
understand. So I do see a correlation between high evaluation scores and
other indicators. But more to the point, these tests were developed using
other written and verbal evaluations. They were developed using interview
protocols, so they are certainly fairly accurate.

The bottom line is that you may be achieving exactly what you think, but you
have little hard evidence unless you pre and posttest using these
instruments.

Does this strike anyone else as internally inconsistent?
* The basis for the validity of "these tests" is detailed interviews, etc.
* Yet, having the results of detailed interviews (as Edmiston described)
is considered "little hard evidence".

Sure, the detailed interviews would make comparisons between
institutions difficult, even if they were recorded (which I'm sure they
were not). But such a comparison is irrelevant to the conclusion being
drawn.

Sorry for a post that will be meaningless unless you have followed the
thread...
