This project was a field research experience designed to enhance the capacity of middle and high school teachers to incorporate active research into their classroom teaching. Evaluation was designed for both formative and summative purposes. All activities in the project had the goal of using inquiry-based learning in the classroom. Teams of one teacher and two students (for a total of 44 teachers and 86 students) participated in pre- and post-institute field and research projects. The project staff worked with each team before, during, and after the institutes to assist with all project activities. The institute activities were used to give teachers sufficient practice doing fieldwork and active research. Teachers saw how the science techniques worked or did not work and learned to be flexible. Not only could students create their own questions and design experiments, but they could also use statistical procedures to test their null hypotheses. (KHR)
