Used hierarchical linear modeling with data from the New Brunswick School Climate Study (Canada) to examine student background, school context, and school climate effects on Grade 6 student achievement in mathematics, science, reading, and writing. Gender, socioeconomic status, and Native ethnicity were significant predictors of academic…

A stimulus preference assessment was evaluated with an adult and a child with profound mental retardation and severe self-injurious behavior, in order to better predict both the beneficial and negative side effects of stimuli in differential-reinforcement-of-other-behavior treatments. (DB)

University undergraduates (n=207) reported a diverse range of childhood disciplinary history and their perceptions regarding that history. Analysis indicated that, among those with severely punitive histories, individuals who did not label themselves as abused were less likely to classify events as physically abusive than those who labeled…

Investigated the validity of the Swedish model for selection to higher education, using S. Messick's (1989) four-faceted model of validity and grade-point-average and admissions test data for 314 college students. Results challenges the unidimensional use of the selection instruments. (SLD)

Recent negotiations to amend the tuition reciprocity agreement between Minnesota and Wisconsin would require Wisconsin students attending the University of Minnesota-Twin Cities campus to pay a tuition surcharge. Simulations of how the proposed changes would affect enrollment and revenue showed that the proposed surcharge would not adversely…

It has been hypothesized that exposure to stress and negative life events is related to poor health outcomes, and that differential exposure to stress plays a role in socioeconomic disparities in health. Data from three waves of the Americans' Changing Lives study (n = 3,617) were analyzed to investigate prospectively the relationship among…

This study addressed 2 questions: (a) Can preschoolers who will fail at reading be more efficiently identified by targeting those at highest risk for reading problems? and (b) will auditory temporal processing (ATP) improve the accuracy of identification derived from phonological processing and oral language ability? A sample of 227 preschoolers…

Background: Phonological awareness tests are known to be amongst the best predictors of literacy; however their predictive validity alongside current school screening practice (baseline assessment, pupil background data) and to National Curricular outcome measures is unknown. Aim: We explored the validity of phonological awareness and orthographic…

The study investigated achievement status as a factor determining the use of language-based activities for learning science. A total of 154 eighth-grade students were randomly assigned to four groups, all stratified for gender and achievement level. The treatments involved various combinations of talk and writing, and descriptive and explanatory…

In this 2-year longitudinal study the developmental relationships among letter knowledge, phonological awareness, rapid naming, and task orientation were examined, and linguistic-motivational pathways of word reading acquisition were traced from kindergarten to Grade 1 by means of structural equation modeling. The participants were 100…

This paper presents a methodological approach based on Bayesian Networks for modelling the behaviour of the students of a bachelor course in computers in an Open University that deploys distance educational methods. It describes the structure of the model, its application for modelling the behaviour of student groups in the Informatics Course of…

The authors examined whether people can use their knowledge of the wider discourse rapidly enough to anticipate specific upcoming words as a sentence is unfolding. In an event-related brain potential (ERP) experiment, subjects heard Dutch stories that supported the prediction of a specific noun. To probe whether this noun was anticipated at a…

Despite the importance of understanding the emotional aspects of organizational decision making, prior research has paid scant attention to the role of emotion in escalation of commitment. This article attempts to fill this gap by examining the relationship between negative affect and escalation of commitment. Results showed that regardless of…

During practical science Sc1 experiments, some children find making predictions very difficult. The use of scenarios seems to be an excellent way of encouraging children to think creatively about what might happen and focus their attention on what they should experience. If children use carefully selected and explained data, it can help them to…

The purpose of this paper is to describe an instructional sequence where students invent a method for locating lines of eigenvectors and corresponding solutions to systems of two first order linear ordinary differential equations with constant coefficients. The significance of this paper is two-fold. First, it represents an innovative alternative…
