Stimulated recall from videotapes of the lessons of six teachers in two elementary schools was used to obtain data on teachers' interactive thoughts and cognitive processes. A content analysis system was developed and used to examine the transcribed recall interviews. The information processing of all six teachers conformed to a broad pattern. Teacher thoughts were principally about lesson tactics to be used next, past lesson events, expectations for students, and predictions about future lesson developments. Teachers had few thoughts about lesson plans, lesson objectives, past teaching behavior, and its impact on students and the lesson. Some cognitive behavior of teachers was similar to that of clinicians. (Authors)
