This paper traces the sophisticated negotiations to re-inscribe the authority of Nature when a school science experiment fails during the enactment of a highly rated science curriculum unit. Drawing on transcriptions from classroom videotapes, we identify and describe four primary patterns of interaction that characterize this process, arguing…

Some researchers have argued that it is important to match teaching styles with students' learning styles, although a relatively small amount of research has been done on learning styles in science. This study focused on the differences between male and female secondary school chemistry students in an effort to determine the relationship of gender…

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…
