Educational effectiveness research has provided evidence about the importance of teacher beliefs and attitudes for teaching and learning. This study builds on the concept of academic optimism, which combines 3 aspects of a teacher's professional creed: self-efficacy, trust, and academic emphasis. The study explores the functioning of the…

Principals' instructional leadership may support the degree to which teachers work together to improve instruction, and together leadership and teacher collaboration may contribute to school effectiveness by strengthening collective efficacy beliefs. We found a significant direct effect of leadership on teacher collaboration. Further, leadership…

The main objective of this study was to quantify the impact of failing to account for measurement error on school compositional effects. Multilevel structural equation models were incorporated to control for measurement error and/or sampling error. Study 1, a large sample of English primary students in Years 1 and 4, revealed a significantly…

Academic emphasis, collective efficacy, and faculty trust in students and parents (3 school characteristics positively associated with student achievement) are assumed to form a higher order latent construct, "academic optimism" (Hoy, Tarter, & Woolfolk Hoy, 2006a, 2006b). The aim of the present study is to corroborate the latent…

Purpose: This study aims to explore the impact of school leadership, particularly that of the principal (head teacher), on school improvement in England. Design/methodology/approach: The study adopts a mixed-methods (MM), longitudinal design to investigate the leadership of a sample of academically effective and improving schools identified from…

Purpose: The aim of this study was to examine the means by which principals achieve an impact on student achievement. Research Design: Through the application of structural equation modeling, a mediated-effects model for school leadership was tested, using data from 97 secondary schools in the Netherlands. Findings: The results showed a small…

Background/Context: In the Fall 2006 issue of AERJ, Hoy, Tarter, and Woolfolk Hoy identified the new construct of academic optimism as a general latent concept related to student achievement even after controlling for SES, previous performance, and other demographic variables. Through structural equation modeling, they found that the collective…

School effectiveness research often uses multilevel models in which only direct effects of characteristics of schools on pupil achievement are modelled. Recently, more attention is given to conceptual models that assume indirect and antecedent effects. In this paper, we elaborate on these models and show that the findings from school effectiveness…

This study examines (1) the generalizability of a principal instructional leadership model proposed by Bossert, Dwyer, Rowan, and Lee (1982) across school levels, and (2) whether elementary principals exert more influence over school achievement than secondary principals. Findings supported (1) but not (2). Theoretical and practical implications…
