The research problem addressed in this study was the lack of trust between faculty-principal, faculty-client, and faculty-colleague in U.S. secondary schools. The purpose of the study was to determine the relationship between communicator styles and perceptions of trust. Organizational trust theory served as the theoretical foundation. A…

Addresses two related problems: what are the appropriate measures for comparing effects of blocks or compounds of variables (each block conceived as having a single effect) when the causal ordering is assumed to be known, and how can single measures be created for each such block or compound, so that the comparisons can be made.

Educational research on the factors of student achievement has been limited by its failure to consider the multilevel or hierarchical nature of most data. This study used a nonexperimental regression-based procedure, hierarchical linear modeling (HLM), to empirically develop a predictive model of fifth-grade achievement in reading and mathematics…

This paper describes an analytical solution to a common problem in aptitude-treatment interaction (ATI). The researcher is often interested in the comparison between treatments for a large set of attributes. If this set is large, the chance of non-orthogonality is correspondingly large. In these circumstances the analysis and interpretation…

Multiple sources of complications in the analysis of multilevel educational data are described with emphasis on the determination of a method of analysis that will provide accurate estimates of teacher/class effects even when there are systematic differences in within-class regressions of outcome on input associated with teacher/class…

The effectiveness of schools and the levels of investment in schooling have been in question since the 1966 Coleman report "Equality of Educational Opportunity." Based on a theory of "knowledge-ability," this study challenges the assumption that given "inputs" will yield equivalent effects or "outputs." In…
