The theoretical and empirical underpinnings of teacher efficacy are examined to bring coherence to the construct and its measurement. First, we explore the correlates of teacher efficacy revealed using various instruments and search for patterns that suggest a better understanding of the construct. Next, we introduce a model of teacher efficacy that reconciles two competing conceptual strands found in the literature. Then we examine implications of the research on teacher efficacy for teacher preparation and suggest strategies for improving the efficacy of inservice teachers. Finally, we propose new directions for research in light of the proposed model.

This analysis synthesizes existing research to discuss how teachers' practice and student learning are affected by perceptions of collec-

Researchers have been challenged to go beyond socioeconomic status in the search for school-level characteristics that make a difference in student achievement. The purpose of the present study was to identify a new construct, academic optimism, and then use it to explain student achievement while controlling for socioeconomic status, previous achievement, and urbanicity. The study focused on a diverse sample of 96 high schools. A random sample of teachers from each school provided data on the school’s academic optimism, and student achievement scores and demographic characteristics were obtained from the state department of education. A confirmatory factor analysis and hypothesis tests were conducted simultaneously via structural equation modeling. As predicted, academic optimism made a significant contribution to student achievement after controlling for demographic variables and previous achievement. The findings support the critical nature of academic optimism.

This article is a theoretical and empirical analysis of the construct of collective teacher efficacy. First, a model of collective efficacy was elaborated for use in schools. Then, an operational measure of collective teacher efficacy was developed, tested, and found to have strong reliability and reasonable validity. Finally, using the instrument to examine urban elementary schools in one large midwestern district, collective teacher efficacy was positively associated with differences between schools in student-level achievement in both reading and mathematics.
