Are Teacher Effects Larger in Small Classes?


"Teachers spend most of their school time in classrooms and their instruction and teaching practices are affected by classroom context. One important indicator of classroom context is classroom size. It is plausible that teachers in small classrooms may be more effective than teachers in regular size classrooms due to the higher likelihood of teacher-student interactions and learning opportunities in small classrooms. We examine whether teacher effects are more pronounced in small classrooms than in regular size classrooms. We also examine teacher effects for high and low achievers within small and regular size classrooms. Results overall indicate that teacher effects are important in small and regular size classrooms and benefit all students. There is some evidence however that low achievers benefit more from effective teachers in small classes and that high achievers benefit more for effective teachers in regular classes."
