An electronic portfolio system, designed to serve as a resource-based learning space, was tested in a fifth-grade science class. The control-group students accessed a traditional folder-based information display in the system and the experimental-group students accessed a concept map-based information display to review a science portfolio. The…

The purpose of this study is to determine the extent to which cognitive and non-cognitive measures predict academic success for conditionally-admitted students enrolled in a comprehensive public university. Stepwise multiple regression analyses reveal that one cognitive variable (high school grade point average) and two non-cognitive measures…

This study examined the relationship between morphological awareness and reading comprehension in English among Spanish-speaking English language learners (ELLs) followed from fourth through fifth grade. Students' ability to decompose derived words while reading was assessed using an experimental task. Multiple regression analyses were used to…

Vocational psychology has generated a number of concepts and assessment instruments considered to reflect ability self-concept (i.e., one's view of one's own abilities) relevant to career development. These concepts and measures often are categorized as either self efficacy beliefs or self-estimated (i.e., self-rated, self-evaluated) abilities.…

This study proposes relationships between job satisfaction, affective commitment (organization, supervisor and workgroup), and exchange relations with supervisor, organization and workgroup members among extension personnel. Perceived self-esteem (SE) is hypothesized to moderate relations between the social exchange foci and the corresponding…

High school is a time when most gay, lesbian, and bisexual (GLB) youths experience a great deal of distress related to the stigma attached to being gay. Many try to avoid stigmatization by concealing the fact that they are GLB. This brief report presents a descriptive, multidimensional approach to understanding GLB stigma concealment as a…

This article provides an integrated critical review of the literature on internalized heterosexism/internalized homophobia (IH), its measurement, and its psychosocial correlates. It describes the psychometric properties of six published measures used to operationalize the construct of IH. It also critically reviews empirical studies on correlates…

A high correlation has been found between domestic violence and stalking. However, very few studies have examined what factors predict the occurrence of stalking in relationships characterized by domestic violence. Using in-depth interviews with victims of domestic violence whose cases have gone through the criminal justice system, this article…

Attrition from the sciences remains a national problem. The authors present results from a survey of over 2,100 undergraduates that, contrary to previous research, suggests that teaching assistants (TAs) influence student retention in the sciences in multiple ways. Multiple linear regression (MLR) and student comments suggest that TAs influence…

The purpose of this study was to develop an age-generalized regression model to predict maximal oxygen uptake (VO sub 2 max) based on a maximal treadmill graded exercise test (GXT; George, 1996). Participants (N = 100), ages 18-65 years, reached a maximal level of exertion (mean plus or minus standard deviation [SD]; maximal heart rate [HR sub…

The purpose of this study was to investigate the relationship between the cognitive style and teaching style preferences of instructors enrolled in the Reserve Officer Training Corps instructor course at the Academic Instructor School at Maxwell Air Force base. Sixty-five cases were examined for two research questions: (1) To what extent is there…

While the physical correlates of knee osteoarthritis are well documented, less well documented are aspects of psychological functioning that may affect overall health and functional status. This paper describes the findings of a cross-sectional analysis that examined the strength of the relationship between selected psychological factors and the…

This study extended the work of S. Siddiqui, R. F. West, and K. E. Stanovich (1998), who studied the link between general print exposure and syllogistic reasoning. It was hypothesized that exposure to certain text structures that contain well-delineated logical forms, such as popularized scientific texts, would be a better predictor of deductive…

This study examined the correspondence between parent and adolescent reports of the adolescent's substance use in a population of parents concerned about, and experiencing problems resulting from, their teen's substance use. Seventy-five parents and their adolescents (76% not in treatment; 24% in treatment) were interviewed separately regarding…

The idea of "information commitments" refers to both learners' online searching strategies and the evaluative standards that students use to assess the accuracy and usefulness of information in web-based learning environments. Based upon the results of a pioneering and qualitative study on information commitments, this study aimed to develop an…
