In studies of relatives, conventional multiple regression may not be appropriate because observations are not independent. Obtaining estimates of regression coefficients and correct standard errors from these populations through a structural equation modeling framework is discussed and illustrated with data from twins.

Previous research has provided support for the mediating role of self-efficacy between independent attitude variables and dependent performance measures. However the existence of a confirmatory model, that can be generalized over both males' and females' measures of attitudes, perceived self-efficacy, and achievement levels, has not yet been…

This study utilizes the Theory of Planned Behavior (TPB) as the theoretical framework from which to explore the factors that have a determining influence upon science and mathematics achievement. The study makes every effort to expand the utility of TPB by assessing its applicability with respect to the achievement of 10th grade female Palestinian…

Student socioeconomic status (SES) and the perceptions of students' and teachers' expectations and attributions of responsibility for learning and their relationships to achievement were studied using linear structural equation modeling. Two models were developed and tested. One model included student expectations and attributions of…

This study tested a causal model of the influence of tutor behavior on student achievement and interest in the context of problem-based learning. Data were gathered from 524 tutorial groups involving students in the health sciences curriculum at the University of Limburg in the Netherlands during 1992-93. Correlations among the 261 tutors' social…
