The quantity versus the distribution of teacher behavior

The overall quantity and distribution of teacher interaction are the respective concerns of research on teacher effectiveness and research on teacher expectations. Factors that have kept both these research areas and their applications to teacher education distinct are considered. Limitations of teacher education programs that deal with either the quantity or distribution of teacher behavior are noted. Next, research that examines both indices of teacher behavior is considered. The paper ends with suggestions for how the content and sequencing of teacher education programs could benefit from an integration of quantity and distribution concerns.
