Primary science education is a concern around the world and quality mentoring within schools can develop pre-service teachers' practices. A five-factor model for mentoring has been identified, namely, personal attributes, system requirements, pedagogical knowledge, modelling, and feedback. Final-year pre-service teachers (mentees, n = 211) from…

Objective: Our knowledge of how acculturative processes affect families remains quite limited. This article tests whether acculturative family distancing (AFD) [1], a more proximal and problem-oriented measure of the acculturation gap, influences the mental health status of Asian American and Latino college students. AFD occurs along two…

The present study examined the validity of the Basic Empathy Scale (BES) [Jolliffe, D., & Farrington, D. P. (2006a). Development and validation of the Basic Empathy Scale. "Journal of Adolescence," 29, 589-611; Jolliffe, D., & Farrington, D. P. (2006b). Examining the relationship between low empathy and bullying. "Aggressive…

In recent years, considerable attention has been paid to the alleged changes in the ways the so-called "digital generation" communicates and learns. Most of the commentary has been based on anecdotes, observations and opinions. The lack of empirical evidence in this matter suggests that it may be time to begin the process of gathering…

In the Netherlands, national assessments at the end of primary school (Grade 6) show a decline of achievement on problems of complex or written arithmetic over the last two decades. The present study aims at contributing to an explanation of the large achievement decrease on complex division, by investigating the strategies students used in…

With the growing emphasis on accountability and evidence-based practice, evaluation has become increasingly important in the contexts in which educational psychologists (EPs) practice. This paper describes a Target Monitoring and Evaluation (TME) system, derived from Goal Attainment Scaling (GAS) which was developed to evaluate outcomes of a wide…

Objectives: To investigate the psychometric properties of the BMSLSS-College among 723 college students. Methods: Internal consistency estimates explored scale reliability, factor analysis explored construct validity, and known-groups validity was assessed using the National College Youth Risk Behavior Survey and Harvard School of Public Health…

The purpose of this study was to examine the performance of the Thai-version of WHOQOL-BREF in assessing the quality of life (QoL) among Thai college students. The psychometric properties of WHOQOL-BREF were assessed in this study. The self-administered WHOQOL-BREF questionnaire was applied. A total of 407 Thai college students (male age = 20.5…

Empirical research on anger and hostility has pervaded the academic literature for more than 50 years. Accurate measurement of anger/hostility and subsequent interpretation of results requires that the instruments yield strong psychometric properties. For consistent measurement, reliability estimates must be calculated with each administration,…

The Rasch model of latent trait test theory is extended to multiple choice questionnaires. The statistical development and logic of the extension is presented and implications of the extension are discussed. (JKS)

It is shown that, under very general conditions, uniqueness estimates proposed independently by Guttman (1957) and by Harris (1963) provide tighter upper bounds on the unknown uniqueness values of factor analysis than do existing estimates. (Editor)

This paper made an important distinction between determinacy of common-factors and determinacy of unique-factors and examined the implications of two results previously obtained by Guttman. (Author/RK)

Recent attempts have been made to find a robust method for comparing the variances of "J" dependent random variables. However, these procedures can give unsatisfactory results. Several new procedures that are derived heuristically are examined. The most effective method is based on the statistic derived by D. Quade. (TJH)
