Continuing concern regarding the undergraduate chemistry laboratory curriculum has prompted research of alternative lab activities to the traditional verification experiments. Inquiry based activities have been reported to improve student understanding, however many large universities have not changed their lab courses in decades. In such institutions the graduate students instruct many of the general chemistry lab courses. This study was implemented at a large university in which six out of nineteen first semester general chemistry labs substituted their traditional one-week verification experiments for inquiry-based labs which utilized cooperative learning strategies to teach problem-solving ability, higher cognitive thinking, chemistry content and social skills. The study was evaluated by qualitative methods through examination of the students, the graduate teaching assistants, and all artifacts. This paper focuses on the findings with respect to the graduate teaching assistants and how their interactions with students, attitudes towards inquiry learning, and educational philosophies evolved during the semester.
