Provides an integrative review that concentrates on two of the perceived major impediments for integrating science and mathematics: the lack of evidence to support integration, and the lack of a definition for integration. Identifies and defines the forms of integration found from a meta-analysis of 31 studies on integration. (Contains 61…

Performs analysis on a number of articles published between 1985 and 1995 describing experimental research into the effectiveness of a wide variety of teaching strategies for science problem solving. Identifies 22 articles describing 40 experiments that met standards for meta-analysis. Indicates that few of the independent variables were found to…

This article examines the statistical correction for attenuation and the controversies surrounding the procedure. The logic of the double and single correction formulas is discussed, and misapplications and misinterpretations of the correction are presented. (SLD)

Investigates, in two experiments, whether scores on the Role Category Questionnaire (RCQ) predicted the amount of psychological knowledge activated about others. Uses meta-analytic comparison of the results from the experiments to suggest that RCQ scores significantly predict the amount of conceptual psychological knowledge activated about others.…

Conducted a quantitative meta-analysis evaluating the effects of systematic phonics instruction compared to unsystematic or no phonics instruction on learning to read using 66 treatment-control comparisons derived from 38 experiments. Results show that systematic phonics instruction is effective and should be implemented as part of literacy…

A 20-year review of literature on return to work outcomes for ill or injured persons found that research is largely atheoretical and the knowledge base fragmented. The Occupational Competence Model can fill this gap by reflecting the multidimensional nature of work disability (personal, environmental, and occupational dimensions) and factors…

Reports on a survey of eclecticism and integrationism in counselors and other therapists. Results indicate that nearly 87% of counselors reported multiple orientations and approaches alongside a wide range of techniques. Findings suggest that eclecticism and integrationism are the preferred modes of approach, especially for the more experienced…

Maintains that the results of Wellman, Cross, and Watson's meta-analysis on the false belief task are perfectly compatible with "early competence" accounts that posit a specific, innate, and possibly modular basis for theory of mind. Asserts that Wellman and colleagues' arguments against such views stem from mistaken assumptions…

Gender differences in the efficacy of nicotine replacement therapies (NRTs) were examined in a meta-analytical review of 90 effect sizes obtained from a sample of 21 double-blind, placebo-controlled randomized studies. Although NRT was more effective for men than placebo at 3-month, 6-month, and 12-month follow-ups, the benefits of NRT for women…

This meta-analysis reviews 208 laboratory studies of acute psychological stressors and tests a theoretical model delineating conditions capable of eliciting cortisol responses. Psychological stressors increased cortisol levels; however, effects varied widely across tasks. Consistent with the theoretical model, motivated performance tasks elicited…

A meta-analysis of 95 studies was conducted to investigate the relations of heart rate (HR) and electrodermal activity (EDA) with aggression, psychopathy, and conduct problems. Analyses revealed a complex constellation of interactive effects, with a failure in some cases of autonomic patterns to generalize across antisocial spectrum behavior…

I studied rater effects in the writing and speaking sections of the Test of German as a Foreign Language (TestDaF). Building on the many-facet Rasch measurement methodology, the focus was on rater main effects as well as 2- and 3-way interactions between raters and the other facets involved, that is, examinees, rating criteria (in the writing…

This meta-analysis investigated the influence of assessment on the reported effects of problem-based learning (PBL) by applying Sugrue's (1995) model of cognitive components of problem solving. Three levels of the knowledge structure that can be targeted by assessment of problem solving are used as the main independent variables: (a) understanding…

The last two decades have witnessed a surge in interest in research on organizational identification (OI). This paper presents a comprehensive meta-analysis of this research (k=96). Results indicate that (a) OI is correlated with a wide range of work-related attitudes, behaviors, and context variables, (b) OI is empirically distinct from its…

This study is intended to review some of the selected researches carried out on students' understandings of enthalpy and spontaneity. The review puts together the important findings of the researches, summarises the misunderstandings identified so far and the possible sources of these misunderstandings. Therefore, this study would be beneficial…
