Thanks for the feedback, Robert. I would be happy to share my exams for both my first year and second year courses. I would not, however, say that I have "changed my course to increase the FCI." I've changed my course to better teach physics. The FCI is one measure... unfortunately it is the only measure I used initially (I also use the Mechanics Baseline Test now... but I don't have previous data to compare). The FCI does a good job with just ONE aspect of high school physics: Newton's Laws. I teach much more than just Newton's Laws, but I figured that if my students didn't understand Newton's Laws, everything else I was doing was just going into a big confusing mess in their brains. That is, Newton's Laws are the sine qua non of intro physics. My overall goal is to get the students to use Newton's Laws, Conservation of Energy and Conservation of Momentum (and in the second year course, Conservation of Angular Momentum) to solve a great many problems... that is, I try to get them to see the parsimony of physics. I don't do this by teaching a "conceptual" course.
My email is in my profile. Shoot me a message and I'll get my exams to you. I'd love to get your feedback.
