Student perceptions of the behavior of physics teachers in relation to selected variables in the classroom setting were investigated. High correlations between student perceptions of teacher behavior and affective outcomes are reported. (CW)

Subjects (N=41) were randomly assigned to one of two groups defined by the teacher's clarity in a genetics lesson: low-clarity versus high-clarity.

This study reports on the science achievement and attitudes of seventh- and eighth-grade students whose teachers were considered exemplary. Results show that this group of students, compared to national populations, had higher scores in science knowledge and more positive science attitudes. These students need opportunities to make connections…

A meta-analysis was conducted of 65 studies related to relationships between science teacher background characteristics and either their classroom behavior or student outcomes. In general, low relationships were found between these characteristics and classroom teaching behavior and student outcome characteristics. Summary tables showing strongest…
