title = "Who does what? A linguistic approach to analyzing teachers' reactions to videos",
abstract = "This paper describes a technique for analyzing teachers' reactions to videos. The technique uses Halliday's systemic functional linguistics to identify teachers' perceptions of the division of labor between teachers and students when working on a mathematical task. The author uses the technique to analyze data from focus group sessions where teachers reacted to a video episode. The author argues that the technique could be particularly useful for studying teachers' perspectives about novel teaching activities, such as problem-based instruction in mathematics.",

Funding Information: The data for this article were collected by geometry, reasoning, and instructional practices (GRIP), a mathematics education research group directed by Patricio Herbst in a project funded by the National Science Foundation. The research group convened 5 different focus group sessions with 30 geometry teachers from 23 different schools. The focus group sessions were videotaped using two cameras facing participants at a wide angle throughout the sessions. The sessions were fully transcribed.",
