Abstract

Using two independent samples of urban elementary school children from Grades 1, 3, and 5, this study explored the long-term stability of classroom learning environments that differ in the extent of differential teacher treatment favoring high achievers over low achievers, as reported by students. Classroom differences ('high' versus 'low') in perceived differential treatment were highly stable from fall to spring in Grades 3 and 5, but not in Grade 1. Stability in (a) individual children's reports of differential treatment, and (b) teacher expectations for children's year-end reading achievement was accentuated in classrooms where differential treatment was pronounced early in the year, particularly in the higher elementary grades. Findings suggest that there would be heightened risk for problematic teacher expectancy effects and other maladaptive learning outcomes in these classrooms, because stable or rigid performance expectations are coupled with classroom instructional patterns that consistently convey these expectations to children. In contrast, risk is likely to be reduced in classrooms where high and low achievers are treated more equitably in the eyes of children, because teachers' expectations for children are more flexible, and children take longer to discern differences in treatment. The overall consistency of findings in two samples supports the generalizability of the conclusions reached.
