This article reports a study of the learning environments in computer networked classrooms. The study is unique in that it involved an evaluation of both the physical and psychosocial classroom environments in these computerised settings through the use of a combination of questionnaires and ergonomic evaluations. The study involved administering…

This study is a replication of an original study conducted by James and Blank (1991) which examined the relationship between educational attainment and adult performance using the Multi-Modal Paired Associates Learning Test-Revised (MMPALT-II) (Cherry, 1981). The MMPALT-II was designed to measure an individual's demonstrated perceptual modality…

Computer algebra methods based on results of commutative algebra like Groebner bases of ideals and elimination of variables make it possible to solve complex, elementary and non elementary problems of geometry, which are difficult to solve using a classical approach. Computer algebra methods permit the proof of geometric theorems, automatic…

The paper's aim is to note a remarkable (and apparently unknown) relation for right triangles, its generalisation to arbitrary triangles and the possibility to derive these and some related relations by elimination using Groebner basis computations with a modern computer algebra system. (Contains 9 figures.)

A mathematician's work consists of proving theorems, calculating, and making mathematics understandable. An assistant for all three components is a Computer Algebra System. We describe and discuss various CAS-assisted processes for proving theorems, and discuss the constraints which can appear regarding efficiency, confidence in the result and…

Objective: The aims of this study were to examine (1) the psychometric properties of the Childhood Trauma Questionnaire [CTQ; Bernstein, D., Fink, L., Handelsman, L., Foote, J., Lovejoy, M., Wenzel, K., Sapareto, E., & Ruggiero, J. (1994). Initial reliability and validity of a new retrospective measure of child abuse and neglect. American…

The purpose of this study was to develop a valid and reliable instrument to measure the Social Cognitive Theory (SCT) constructs of smoking refusal skill-efficacy, positive smoking refusal outcome expectations & importance and negative smoking refusal outcome expectations & importance. This article details the rigorous instrument development…

Currently a sound and reliable measure of a student-athlete's career development does not exist. The purpose of this study was to develop a psychometrically sound instrument that measures the career situation of student athletes. Participants for the study were 204 (138 male and 66 female) student-athletes from a large midwestern Division I…

Motivating students to perform well on assessment tests is difficult when students know the results have no academic consequence. The present study evaluates the influence of assessment context (graded vs. non-graded) on the reliability of an assessment measure. Results indicate the graded condition produces higher reliability (r = 0.71) than the…

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…

The current study investigated whether acute alcohol intoxication produces impaired decision-making on tasks assessing ventromedial prefrontal (VMF) cortex functioning and impulsive responding. Participants completed the Iowa Gambling Task (IGT), a decision-making test targeting the VMF, and the Newman Perseveration Task (NT), a measure of…

We examined the gender appropriateness of the DSM-IV symptoms of attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD). In Study 1, 100 mothers (35 of children with and 65 of children without ADHD) rated how gender-typical and problematic they saw DSM-IV symptoms of ADHD, ODD, and CD;…

The current study reexamined the factor structure of the Lifetime and Recent scales of the Schedule of Sexist Events (SSE; Klonoff & Landrine, 1995) and conducted the first factor analysis of the SSE-Appraisal scale ( Landrine & Klonoff, 1997). Factor analyses conducted with data from 245 women yielded, for SSE-Lifetime and SSE-Appraisal scales,…

The validity of the Norwegian university grading standard has been called into serious question. The implicit standards used for assessing exams and the reliability of that understanding among examiners and psychology students were investigated in three studies. Studies 1 and 2 investigated the implicit standards that examiners used when assessing…

This article examines a subset of acculturation items pertaining to language fluency and use and to interpersonal relationships. This study included 3,050 Mexican American elders aged 65 to 99, randomly sampled from five states in the southwestern United States. A standard acculturation inventory was used as the source for two factor-derived…
