Participants took a basic Physics content knowledge test that was designed by a Professor of Physics. The test was completed before the teachers participated in the program and at the end of the program to gather data for statistical inquiry. Statistical studies on pre-test and post-test data indicated significant gains in physics content knowledge over time, and that instructors teaching at the middle school level or only teaching one subject area scored significantly lower during the pretest. Reports from previous participants are summarized to disseminate the percentage of teachers who have incorporated at least one workshop activity and the kind of activity performed. The concerns and limitations reported by previous participants are reviewed as well.}, journal={12TH EDUCATION AND TRAINING IN OPTICS AND PHOTONICS CONFERENCE}, author={Gilchrist, Pamela Olivia and Hilliard-Clark, Joyce and Bowles, Tuere and Carpenter, Eric}, year={2014} }
