Doing Chemistry is a practical resource for high school chemistry teachers that ties the specifics of classroom chemistry content to teaching practice. This final evaluation focused on the evaluation of workshops for teachers. An 81% return on a survey of the 206 lead teachers who participated in the National Science Foundation-funded Doing Chemistry workshops indicated that within this 18-month period, 90% of those teachers showed the materials to 2,500 colleagues, 50% gave 84 workshops involving 2,600 teachers, and 10% presented the materials as posters or papers to 1,700 colleagues. The acquisition of hardware for use with Doing Chemistry has proved difficult. However, 66% of the teachers who returned surveys had the equipment, and an additional 25% had plans to acquire the equipment. The teachers enthusiastically endorsed the workshops and the workshop leaders. (PR)
