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…

The main objective of the proposed study was to explore Teacher--Student verbal interaction patterns at tertiary level education in the North West Frontier Province of Pakistan using Flanders' Interaction Analysis system. This study was significant because its findings and conclusions may stimulate teachers to improve their teaching behaviour in…

Most psychology journals now require authors to report a sample value of effect size along with hypothesis testing results. The sample effect size value can be misleading because it contains sampling error. Authors often incorrectly interpret the sample effect size as if it were the population effect size. A simple solution to this problem is to…

This paper examines the hypothesis that grammatical function reanalyses in simple sentences should not be treated as phrase structure revisions, but rather as increased costs in "linking" an argument from a syntactic to a semantic representation. To this end, we investigated whether subject-object reanalyses in German verb-final sentences can be…

Faith schools are popular with parents and feature towards the top of the annual tables of school performance in England based on the government's preferred measures of school outcomes. Academic studies suggest that although the observed differentials between the faith and non-faith sectors at the end of Key Stage 4 are partly explicable in…

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…
