This paper analyzes discrepant findings from research on science teacher knowledge and classroom discourse. In new science teachers' classrooms, discourse during laboratory activities differed in important ways from discourse during other types of instruction. Furthermore, teacher subject-matter knowledge had effects that were not predicted by the…

An experimental Interactive Video Disc (IVD) assessment program, funded partially by the National Science Foundation, was developed to assess science teachers' knowledge of safe management of lab facilities and activities. The IVD program contains two phases: (1) panoramic view of the lab room, including safety equipment and storage of chemicals;…
