Two experiments investigated learning outcomes and comprehension processes when students learned about the heart and circulatory system using (a) text only, (b) text with simplified diagrams designed to highlight important structural relations, or (c) text with more detailed diagrams reflecting a more accurate representation. Experiment 1 found…

Purpose: The purpose of this study was to determine how school social composition is related to perceived collective efficacy. Several hypotheses tested in this research were derived from social cognitive theory and based on the extant literature. Participants: Data were drawn from 1,981 teachers in 41 K-8 schools in a diverse urban school…

An ecologically framed model is presented describing processes accounting for early adolescents' exposure to community violence in high-risk neighborhoods as a function of risk factors in four ecological domains assessed in the prior year. The model was tested for hypothesized pathways along which the combined domains of risk might operate. The…

In this rejoinder, the authors respond to the insightful commentary of Strohmer and Arm, Chwalisz, and Hilton, Harris, and Rice about the meta-analysis on statistical versus clinical prediction techniques for mental health judgments. The authors address issues including the availability of statistical prediction techniques for real-life psychology…

The ultimate aim of this research is to specify and implement a general authoring framework for content and knowledge engineering for Intelligent Educational Systems (IES). In this context we attempt to develop an authoring tool supporting this framework that is powerful in its functionality, generic in its support of instructional strategies and…

This article is a collaborative initiative of the TESL profession in Manitoba. It reflects the authors' attempts to articulate the role of the ESL teaching profession and practice in Canadian multiculturalism. Recognizing ESL teachers' historical roles as agents of assimilation, the authors consider how the field can reorient itself to serve…

Teacher Research Groups (TRGs) provide one means of creating learning communities among teachers with the express purpose of systematically examining practice and enriching teachers' knowledge about learning and teaching. These groups meet regularly, may be facilitated by a more experienced peer or university researcher, assist teachers with the…

The primary core deficit in autism spectrum disorders is social development. While frequently acknowledged as a critical aspect of intervention for improved functioning, research on the specifics of social development and effective models of intervention is not commensurate with the acknowledged importance. We present a model of social competence…

It is argued that the Web is transforming schooling in the 21st century, and as such altering the terrain of what leadership "means." Theorizing our submersion in the Internet, we discover that the Web enhances a "leadership-for" paradigm, while at the same time it militates against what is defined as a "leadership-with" paradigm. For the power of…

The frequency of judgment effect is a special case of Response Mode effect in human covariation and causal learning. Judgment adjustment -to [Delta]P-, depends on the trial type preceding that judgment, but that effect is restricted to situations in which participants are asked to make their judgments with a high frequency. Two experiments further…

The purpose of this study was to (1) create a predictive model that would correctly identify men at greatest risk of dropping out of a court-mandated, batterer intervention program; and, (2) explore the creation of such a logistic regression model using a set of instruments that were different from those used in previous research. Method: The…

The Other 3Rs Project began with an investigation into the most important psychological components of academic success. The research pointed to reasoning, resilience, and responsibility. The objective of the project was to integrate these components into a useful problem solving model that could, with practice and guidance, be applied both inside…

Direct and indirect effects of socioeconomic status (SES) and previous mathematics achievement on high school advanced mathematics course taking were explored. Structural equation modeling was carried out on data from the National Educational Longitudinal Study: 1988 database. The two variables were placed in a model together with the mediating…

Sophisticated software such as Virtual Learning Environments (VLEs) are rapidly being deployed by universities. Despite widespread use of such systems, experience shows that there is frequently poor pedagogic development, leading primarily to use of VLEs as electronic document repositories rather than as online learning systems in which the…

The purposes of the study were (a) to identify perceptions about representative English-language accents from prospective and practicing providers of business-related language services residing in Argentina and (b) to examine the differences in their perceptions of these English-language accents. The respondents ranked the accents in this order:…
