Per definition, CSCL research deals with the data of individuals nested in groups, and the influence of a specific learning setting on the collaborative process of learning. Most well-established statistical methods are not able to analyze such nested data adequately. This article describes the problems which arise when standard methods are…

Objective: The authors investigated the personality characteristics, psychopathology, parenting style, and family function among Taiwanese college students with high, moderate, and low suicidal risks. Participants: The sample included 2,919 first-year college students (1,414 men, 1,505 women) from a university in Taipei, Taiwan. Methods: A…

This study examined the impact of treatment adherence and therapist competence on treatment outcome in a controlled trial of individual cognitive-behavioral therapy (CBT) and multidimensional family therapy (MDFT) for adolescent substance use and related behavior problems. Participants included 136 adolescents (62 CBT, 74 MDFT) assessed at intake,…

The goals of this study were to (a) examine differences between two age groups of adolescents with and without learning disabilities (LD) in their general and specific self-efficacy beliefs (in history and mathematics), their academic achievement (in history and mathematics), and their loneliness, effort, and hope; and (b) identify predictors of…

This paper seeks to advance our understanding of the drop-out behavior of students in higher education. Our results are based on longitudinal data for 7000 students who embarked on short and long programs from one university in Spain and who were observed over an eight-year period ending in 2004. The statistical analysis is carried out in a…

On the basis of a large-scale survey of high-school youth, the authors compared adolescents reporting exclusively heterosexual, mostly heterosexual, bisexual, and predominately same-sex attraction based on high-risk involvement across a range of risk behaviors. Bisexual and same-sex attracted groups were characterized by heightened high-risk…

We explore the immediate and longer term consequences of different types of instruction about a central topic in middle school science: the "Control of Variables Strategy" (CVS). CVS represents the procedural and conceptual basis for designing simple, unconfounded experiments, such that unambiguous causal inferences can be made. CVS…

There are several avenues of inquiry that seek to understand and ameliorate the problem of bullying in schools, including the strategy of fostering respect. To date, however, there is little empirical literature testing the presumed relationship between respect and bullying. This study examined this relationship with surveys (N = 3,147) and…

Student wellbeing can be considered a major output indicator of quality of education. A positive classroom climate can contribute to a higher sense of wellbeing. Interpersonal relationships between teachers and students are an important aspect of the classroom climate. This study investigated how student wellbeing was predicted by student…

A positive school climate is an important component of successful and effective schools and thus is often an aim of schoolwide initiatives. Climate has traditionally been conceptualized as a school-level factor and is often assumed to be related to other school-level factors (e.g., school size). The current study examines variation in perceptions…

Objective: A school-based nutrition education minimal intervention (MI) was evaluated. Design: The design was experimental, with random assignment at the school level. Setting: Seven schools were randomly assigned as experimental, and 7 as delayed-treatment. Participants: The experimental group included 551 teens, and the delayed treatment group…

There is paucity of original research that explains phenomena related to content organization and site design of educational Web sites. Educational Web sites are often used to provide Web-based instruction, which itself is a relatively recent phenomenon for business schools, and additional research is needed in this area. Educational Web sites are…

Participation in various structured out-of-school time (OST) activities benefits youth socially, emotionally, and academically and may have the most positive effects for youth who are most at risk. Little research, however, has explored the questions of who participates in OST activities and why. The Harvard Family Research Project examined the…

The efficiency of schools diverges dramatically across countries in the OECD and can also vary markedly within countries. These differences in levels of efficiency can be traced to policy and institutional settings. As such, moving to best practice could boost educational attainment and reduce pressure on budgetary resources. This paper assesses…

The relationship between musical training and general intellectual capacity as well as academic achievement has been discussed in numerous contexts. In our study, we examined the relationship between participation and achievement in music and achievement in academic courses, based on data from three consecutive British Columbia student cohorts.…
