Multilevel models are often used to evaluate hypotheses about relations among constructs when data are nested within clusters (Raudenbush & Bryk, 2002), although alternative approaches are available when analyzing nested data (Binder & Roberts, 2003; Sterba, 2009). The overarching goal of this article is to suggest when it is appropriate…

Classroom context and climate are inherently classroom-level (L2) constructs, but applied researchers sometimes--inappropriately--represent them by student-level (L1) responses in single-level models rather than more appropriate multilevel models. Here we focus on important conceptual issues (distinctions between climate and contextual variables;…

This article reports results of a confirmatory factor analysis performed to cross-validate the factor structure of the Educators' Attitudes Toward Educational Research Scale. The original scale had been developed by the author and revised based on the results of an exploratory factor analysis. In the present study, the revised scale was given to…

The present study was designed to examine the construct validity, reliability, item difficulties, discrimination indices, effectiveness and efficiency of the CCAT test. (Author)

The purpose of this study was to investigate the relationship between sample size and the quality of factor solutions obtained from exploratory factor analysis. This research expanded upon the range of conditions previously examined, employing a broad selection of criteria for the evaluation of the quality of sample factor solutions. Results…

Common factor scores were compared to unfactored data-level variables as predictors in terms of the correlation of a criterion with the predicted value in multiple regression equations applied to replication (cross-validation) samples. (Editor)

This paper discusses the theoretical scope and practical applicability of generalizability (G) theory through the principle of symmetry. Major ideas are summarized and factors hindering applications of G theory in research conducted in French-speaking Europe are presented. The principle of symmetry affirms that any factor of a design can be…

To investigate degree of variation in factor structures produced using different factor analytic techniques, two large data sets were analyzed using four factor analytic approaches (theoretical conventional, theoretical conventional-confirmatory, modified confirmatory, and pure confirmatory). Data sets included third through seventh graders and…

This study examined factors associated with the curriculum and instructional environments for secondary students with mild mental retardation, based on teacher report. A survey was mailed to 378 secondary special education teachers in Michigan. Teachers provided demographic information and answered questions regarding curriculum and instructional…

The purpose of this study was to investigate the factor structure of a Factors Influencing Pursuit of Higher Education (FIPHE) Questionnaire which addresses factors influencing a person's decision to pursue higher education. Researchers used a literature-based, rational factors approach to develop the questionnaire; the three-part study included a…
