A rigorous quasi-experiment tested the ameliorative effects of a sabbatical leave, a special case of respite from routine work. We hypothesized that (a) respite increases resource level and well-being and (b) individual differences and respite features moderate respite effects. A sample of 129 faculty members on sabbatical and 129 matched controls…

The Job Decision Factors Survey used policy capturing to measure the influence of 7 factors on job decisions. Data from 400 undergraduate students at a large university, 88% 18-25 years of age, 12% 25-65 years of age, 82% female, 54% White, 21% Asian, 10% Black, 10% Hispanic, 1% American Indian, were included in a regression analysis. Hypothesis…

Student perceptions of teacher and classmate support have been identified as a powerful protective factor for a range of children's outcomes. Evidence suggests that students perceive less support as they advance to higher grades, a factor that may be linked to declines in school attendance. This study utilized a sample of 2,616 students enrolled…

The purpose of the present explanatory mixed-method design is to examine the effectiveness of a developmental intervention, Embedded Metacognitive Prompts based on Nature of Science (EMPNOS) to teach the nature of science using metacognitive prompts embedded in an inquiry unit. Eighty-three (N = 83) eighth-grade students from four classrooms were…

This paper reports on research investigating student experiences of learning through face-to-face and online discussions in a political science course in a large Australian university. Using methodologies from relational research into university student learning, the study investigates associations between key aspects of student learning focusing…

The role of African American mothers' academic gender stereotype endorsement in shaping achievement-related expectations for and perceptions of their own children was examined. Mothers (N = 334) of 7th and 8th graders completed measures of expectations for their children's future educational attainment, perceptions of their children's academic…

Objective:This report extends earlier accounts by addressing the effects of the Strong African American Families (SAAF) program across 65 months. Two hypotheses were tested: (a) Rural African American youths randomly assigned to participate in SAAF would demonstrate lower rates of alcohol use than would control youths more than 5 years later, and…

The purpose of the present study was to examine relations between adolescents' social cognitions regarding parenting practices and adolescents' prosocial behavioral tendencies. A mediation model was tested whereby the degree to which adolescents perceived their parents as responding appropriately to their prosocial and antisocial behaviors was…

A diminished top-down influence has been proposed in autism, to account for enhanced performance in low-level perceptual tasks. Applied to perceptual categorization, this hypothesis predicts a diminished influence of category on discrimination. In order to test this hypothesis, we compared categorical perception in 16 individuals with and 16…

The validity of a hypothesis test is partly determined by whether the assumptions underlying the test are satisfied. In the past, a preliminary analysis of the data has been suggested prior to the use of the statistical test. In this article, the authors describe several limitations of preliminary tests (e.g., influence on significance levels).…

We tested McCann's precocity-longevity hypothesis, which proposes that early career achievement is related to premature death, for Major League baseball players (N = 3,760). Age at debut was the definition for precocity. We controlled for possible artifacts of life expectancy selection, the "healthy worker" effect, player position, and body-mass…

The hierarchical linear model (HLM) is now commonly accepted as a useful modeling approach for multilevel data resulting from randomized field experiments. When multiple outcomes of interest exist, a multivariate extension of the conventional univariate HLM offers advantages over the usual application of separate HLM analyses for each of the…

In line with international trends in education, South Africa has embraced inclusive education as the means by which learners who experience barriers to learning will be educated. As inclusion is beginning to be realised in South African schools, a gap in the emerging research base on inclusive education is that of inclusion in the independent…

Our purpose was to advance and test a theoretical model of the nature and function of trust in schools. Unlike other studies, ours specified school trust as a latent construct manifested through parent and teacher trust perceptions. We hypothesized that trust would have a larger direct effect on collective teacher efficacy and achievement…

As collaborative learning in general, and pair programming in particular, has become widely adopted in computer science education, so has the use of pedagogical visualization tools for facilitating collaboration. However, there is little theory on collaborative learning with visualization, and few studies on their effect on each other. We build on…
