Re: post testing FCI

This question (announce the test or not) is one of the many concerns I
personally have over the value that has been placed on the FCI in Physics
Educational Research. If you're using the FCI for your own information,
then it really doesn't matter, but if it is being used for research
purposes, then whether given as an announced test or as a pop quiz does
(IMO) matter. Comparing cross institutional results without this kind of
information (and probably lots of other such variables) then becomes
problematic.

I have given it on the last day of class. I tell the students the
day before that I will be doing it and I take into account the gain
they made over the pretest when I do their final grades. I have
never told them their initial grades.

While some probably blow it off, most seem to put genuine effort into
the work.


We will be post-testing the force concept inventory for our intro class
here at Vassar. Am I correct that the best way to do this is to
announce the quiz beforehand, rather than give it as a pop quiz? I
will probably count the quiz as a regular homework score.

If you have post-tested the FCI before, I'd be interested to hear how
it's done at your school.

Thank you,
