In the present study the effects of a cooperative leadership team, distributed leadership, participative decision-making, and context variables on teachers' organizational commitment are investigated. Multilevel analyses on data from 1522 teachers indicated that 9% of the variance in teachers' organizational commitment is attributable to…

The aim of this study was to identify subgroups of early and mid-adolescents with different drinking trajectories. In addition, we examined whether gender, parental, and peer factors predicted adolescents' membership of these drinking trajectories. We used longitudinal data of 428 families (fathers, mothers, mid-adolescents, and their younger…

This multimethod study of 101 mothers, fathers, and children elucidates poorly understood role of children's attachment security as "moderating" a common maladaptive trajectory: from parental power assertion, to child resentful opposition, to child antisocial conduct. Children's security was assessed at 15 months, parents' power assertion observed…

This study examined pre-service teachers' self-report on their attitude toward computer use. Participants were 285 pre-service teachers at a teacher training institution in Singapore. They completed a survey questionnaire measuring their responses to five constructs which formed a research model using the Technology Acceptance Model (TAM) as a…

While past studies on user-interface design focused on a particular system or application using the experimental approach, we propose a theoretical model to assess the impact of perceived user-interface design (PUID) on continued usage intention (CUI) of self-paced e-learning tools in general. We argue that the impact of PUID is mediated by two…

The authors examined the effects of remedial mathematics on performance in university-level economics courses using a natural experiment. They studied exam results prior and subsequent to the implementation of a remedial mathematics course that was compulsory for a subset of students and unavailable for the others, controlling for background…

The overuse of Massively Multiplayer Online Role Playing Games (MMORPGs) is becoming a significant problem worldwide, especially among college students. Similar to Internet addiction, the pathological use of MMORPG is a kind of modern addiction that can affect students' lives on both a physical and a psychological level. The purpose of this study…

Academic delay of gratification is a significant and positive predictor of students' final course grades, even after controlling for the effect of their rating of the course, expected grade, and degree of interest, importance, and utility of the academic task. Students' expected course grades are by far the strongest predictor of their final…

This study investigated the efficacy of a package of accommodations for poor readers in Grade 7. Students with and without word reading disabilities were randomly assigned to take an experimental version of a high-stakes reading comprehension test in 1 of 3 formats: (a) standard administration, (b) read aloud accommodations with 1-day…

This research set out to explore the attitudes of school, academic and public librarians towards marketing libraries. The main question that was examined is whether personality characteristics such as empowerment, extroversion and resistance to change influence librarians' attitudes towards the marketing of libraries. One hundred and fifty-six…

The purpose of the study was to comparatively investigate student- and school-level factors affecting mathematics achievement of Korean, Japanese and American students. For international comparisons, the PISA 2003 data were analysed by using the Hierarchical Linear Modeling method. The variables of competitive-learning preference, instrumental…

In 2009 the Faculty of Health Sciences at La Trobe University in Melbourne, Australia is introducing a common first year for 11 different undergraduate courses in the faculty. Current prerequisite science entry requirements vary with course and range from none to at least two science or mathematics subjects and from [approximately]50 to 99 in…

The primary goal of this study was to test a credibility-learning model in U.S., Chinese, German, and Japanese classrooms. Using structural equation modeling, an etic credibility-learning model was generated from the common significant paths of the hypothesized model across the four cultures. Teacher credibility showed only an indirect…

Background: Millions of American children are participating in fitness testing in school-based physical education (PE) programs. However, practitioners and researchers in the field of PE have questioned the need for regular or mandatory youth fitness testing. This was partly because a significant improvement in youth fitness and physical activity…

School, parental and peer group effects have been identified as being influential in shaping the decision of students to participate in post-compulsory education, but the analysis of each effect separately is rare. Using a random effects logistic regression approach, estimates of the importance of school, parental and peer group effects on student…
