The Classroom Dialogue schema focuses on helping TAs understand how instructor-student interactions can be used to scaffold students’ engagement with science practices. This schema is built around cycles of pedagogical theory and teaching practice, guiding TAs to analyze authentic classroom dialogue and reflect on pedagogical implications.
TAs were introduced to pedagogical theories, with opportunities to apply these ideas to analyze dialog transcripts from real inquiry-based labs. Over time, TAs were expected to engage with student dialog in more complex and independent ways. Specifically, they moved from observing dialogue structures to identifying instructional strategies, and finally to applying and refining these strategies in their own teaching.
This task presented "decontextualized" dialog from a science classroom, not from the AIM-Bio context. The dialog episodes were designed as a contrasting case to prompt TAs to consider the role of dialog in instruction. This task was used early in the semester to help TAs begin to understand why considering dialog might help them refine their classroom teaching approach.
TAs engaged in a series of tasks in which they considered classroom dialog from the AIM-Bio context and began to: 1) consider the connection between different teaching goals and specific dialog strategies and 2) develop a repertoire of dialog strategies to scaffold students in specific scientific practices.
