My colleague Tony Lawson developed a Classroom Test of Scientific Reasoning and a Nature of Science Survey. The CTSR is valid and reliable and has been used in a number of peer-reviewed studies. I believe the NOSS, which is newer, has also been validated--but I am not certain of this. Julie and Elizabeth, I'll send them to you separately. Anyone else who would like them is welcome to e-mail me at [log in to unmask] Julie Libarkin also developed a NOS survey--see JGE v.49 p. 435.

I would like to administer the instrument pre and post to investigate change in teachers knowledge of the nature of science. Does anybody have a recommendation for a valid and reliable nature of science instrument that would be appropriate for teachers in a PD program?
