This paper explores the idea of perceived value of educational hypermedia by extending prior research in advertising and information systems. It proposes that the value of a course support site comes from both its information content and users' experience when they visit the site. The cognitive antecedents of a site's perceived value include…

With widespread adoption of computer-based distance education as a mission-critical component of the institution's educational program, the need for evaluation has emerged. In this research, we aim to expand on the systems approach by offering a model for evaluation based on socio-technical systems theory addressing a stated need in the literature…

This study investigates the interrelationships of academic causal attributions, academic self-concept, learning approaches, and their effects on academic achievement among Hong Kong Chinese tertiary students. It was hypothesized that academic causal attributions and academic self-concept affect the learning approaches students adopt and…

Structural equation modeling has become increasingly popular as a technique for the analysis of non-experimental data in the social sciences. This increase can be traced in part to the development of computer programs that facilitate structural equation modeling. The Linear Structural Relations (LISREL) program is the most widely used tool for…

A model based on latent trait theory, with maximum likelihood parameter estimates and associated asymptotic tests, is presented. Latent curve analysis is a method for representing development and is an alternative to repeated measures analysis of variance and first-order auto-regressive models. (SLD)

A general structural equation model for measuring residualized true change and studying patterns of true growth or decline is described. This approach allows consistent and efficient estimation of the degree of interrelationship between residualized change in a repeatedly assessed psychological construct and other variables. (SLD)

This study examines the distribution differences across sexes in key measures of self-control theory and differences in a causal model. Using cross-sectional data from juveniles ("n" = 1,500), the study shows mean-level differences in many of the self-control, risky behavior, and delinquency measures. Structural equation modeling…

This empirical research examines the predictors of intended departure for tenured vs. nontenured full-time faculty at research and doctoral institutions across an array of disciplines. What are the characteristics of those who intend to leave their institutions? Do tenured and nontenured faculty show different patterns of intended departure? And…

Purpose: This paper aims to demonstrate that students' self-evaluations contribute to improving academic results and life skills. Design/methodology/approach: Taking as reference a group of previously validated scales (part 1: measurement), a causal model is developed. Hypotheses are tested through the structural equations methodology by using the…

Existing research posits multiple dimensions of bullying and victimization but has not identified well-differentiated facets of these constructs that meet standards of good measurement: goodness of fit, measurement invariance, lack of differential item functioning, and well-differentiated factors that are not so highly correlated as to detract…

The influence of ability, self-efficacy, positivity of role-modeling, and role conflict on higher-level career aspirations was investigated among women majoring in (1) mathematics, physical science, engineering; and (2) biological sciences. Differences between the two groups fit the model. Findings suggest interventions to increase women's…

The Child Abuse Prevention and Treatment Act (1974) requires that states receiving U.S. federal funds directed at child abuse implement mandated reporting laws. As a result, all states have adopted legislation requiring teachers and other professionals who deal with children to report suspicions of child abuse. The federal mandate for such…

One major challenge in using group projects to assess student learning is accounting for the differences of contribution among group members so that the mark assigned to each individual actually reflects their performance. This research addresses the validity of grading group projects by evaluating different methods that derive individualized…

This longitudinal study of physical injury survivors examined the degree to which Hispanic and non-Hispanic Caucasians reported similar posttraumatic stress disorder (PTSD) symptoms. Adult physical trauma survivors (N = 677) provided information regarding posttraumatic distress by completing an interview-administered version of the PTSD Symptom…

At present, it is difficult to assess the quality of learning in Computer-Supported Collaborative Learning (CSCL) environments, because standard pretest and posttest measures do not capture the differences in the learner's ability to engage in the material, pose interesting new questions, engage others in learning and work collaboratively. This…
