One of the most promising avenues of research in computer-assisted language learning is the potential for language learners to make use of language corpora. However, using a corpus requires use of a corpus tool as an interface, typically a concordancer. How such a tool can be made most accessible to learners is an important issue. Specifically,…

Today, it is of great importance that teachers have pedagogical and technological knowledge in addition to content knowledge. For this reason, the present study aims to develop a TPACK self-efficacy scale for preservice science teachers by following the theoretical framework of technological pedagogical and content knowledge (TPACK), as suggested…

Although it is often assumed that mathematics ability alone predicts mathematics test performance, linguistic demands may also predict achievement. This study examined the role of language in mathematics assessment performance for children with intellectual disability (ID) at less severe levels, on the KeyMath-Revised Inventory (KM-R) with a…

A mixed methods design was applied to evaluate the application of the Perceived Locus of Causality scale (PLOC) to preadolescent samples in physical education settings. Subsequent to minor item adaptations to accommodate the assessment of younger samples, qualitative pilot tests were performed (N = 15). Children's reports indicated the need…

This paper reports three studies examining construct validity evidence for two recently developed measures of the positive side of the work-family interface: work-to-family positive spillover (WFPS; Hanson, Hammer, & Colton, 2006) and work-to-family enrichment (WFE; Carlson, Kacmar, Wayne, & Grzywacz, 2006). Using confirmatory factor analysis, the…

This study examined the psychometric properties of the Personal Well-being Index for Adults (PWI-A), a measure of subjective well-being. The study used data from 533 high-ability American college students: honors students and participants in an early college entrance program. In earlier studies using the PWI-A, the instrument appeared to show…

Demands for enhanced accountability and effectiveness in higher education have also affected athletic departments, requiring a more cost-efficient managerial approach to the administration of athletic facilities, especially arenas. The purpose of this study was to examine athletic directors' perceptions towards the arena management models they…

In this article we extend and implement the forward search algorithm for identifying atypical subjects/observations in factor analysis models. The forward search has been mainly developed for detecting aberrant observations in regression models (Atkinson, 1994) and in multivariate methods such as cluster and discriminant analysis (Atkinson, Riani,…

This paper focuses on the relationship between institutional factors and the intention of undergraduate students to withdraw from or complete their distance education courses in the Arab Open University (AOU). The model was examine on a pilot sample of 127 students and then re-examined on the field study of 587 students. Mixed paradigms were…

A method of factor extraction specific to a binary matrix, illustrated here as a person-by-item response matrix, is presented. The extraction procedure, termed ERGO, differs from the more commonly implemented dimensionalizing techniques, factor analysis and multidimensional scaling, by taking into consideration item difficulty. Utilized in the…

A methodology developed as an alternative to conventional institutional classification structures, intended to reduce the limitations of those models, is described. Ways in which the methodology can be used for planning, administrative, and research purposes are discussed, as are the dangers in using "peer groups" for institutional…

Using a sample of 350 college students, this study examined the structural and discriminant validity of the Career Factors Inventory (CFI; Chartrand, Robbins, Morrill, & Boggs, 1990), a multidimensional measure of career indecision intended to be scored for two informational indecision components (Need for Career Information and Need for…

Survey data from 458 former health science graduate students were examined for correlations between variables that might be used in selecting research training award recipients and successful training outcome defined as a highly productive research career. Four variables that showed promise as useful indicators of posttraining research are…

A research program is suggested that integrates admissions procedures and methods of statistical analysis to study the first stage of the admissions selection process: the rating of applicants. A systematic procedure is described that provides an index of applicant "quality" in the light of institutional goals. (Author/MLW)

This study serves as a basis for revisions of the Organizational Climate Description Questionnaire (OCDQ) and as the second part of a larger study in which the conceptual model of climate introduced by Halpin and Croft, and the OCDQ, will be revised. The purposes were (1) to determine the factor structure of the OCDQ when a large, national sample…
