"I then went with more of an inquiry approach. I created my own materials (well, with MUCH help from a colleague... WE created our materials) based off of the Physics By Inquiry materials from U of Washington.
So, hold your hats... the results as measured by the FCI? Not much difference. A bit higher, but not significantly different. More pseudoteaching? Very different teaching, but not what I was looking for in the form of results."
