Nine eighth grade classes were examined to identify the nature, distribution and patterning of verbal discourse. Included are a description of the categories used (Smith and Meux), a description of the nature of the verbal interaction in science lessons, and a resulting comparison between Australian, American, and New Zealand teachers.

Describes a study using two types of macroanalytic analyses of observed teacher behaviors in the classroom. The findings of the study showed one of the macroanalytic techniques to be more effective as it identified broader behavior patterns occurring over longer periods of time. (MLH)

Studied the effectiveness of using checklist-structured observations as a self-improvement technique for modifying teachers' verbal behaviors in the classroom. Concluded that significant changes were found in analyzing pre- and post-treatment audiotape recordings of participating teachers' regular classes. (CC)

Discusses the number of observations necessary to obtain a trustworthy sample of classroom transactions by reanalyzing existing data. Eleven to twenty observations appear necessary for teachers' questions which require students to hypothesize. The reliability of a single observation was zero for four other questioning types. (CC)

This study quantified possible changes in the classroom learning experiences of high- and low-ability pupils, which might accompany an organizational change from streamed to mixed-ability classes for science learning in secondary schools. Deteriorations in the quality of the classroom interactions of both high- and low-ability pupils were found.…
