Randomized clinical trials underpin evidence-based clinical practice, but flaws in their conduct may lead to biased estimates of intervention effects and hence invalid treatment recommendations. The main approach to the empirical study of bias is to collate a number of meta-analyses and, within each, compare the results of trials with and without…

This paper, of theoretical nature, explores the levels of approach and abstraction of research in the field of education policy: description, analysis and understanding. Such categories were developed based on concepts of Bourdieu's theory and on the grounds of epistemological studies focused on education policy and meta-research. This paper…

Social stories play a significant part in the teaching skills and behaviors to children with ASD who lack social skills. The purpose of this study is to analyze studies in which social stories were used for teaching social skills to individuals with Autism Spectrum Disorders (ASD). The present study includes a descriptive review and meta-analysis…

Since its establishment, psychology has struggled to find valid methods for studying thoughts and subjective experiences. Thirty years ago, Ericsson and Simon (1980) proposed that participants can give concurrent verbal expression to their thoughts (think aloud) while completing tasks without changing objectively measurable performance (accuracy).…

A potential source of useful information about undergraduate honors education can be found in doctoral dissertation abstracts that focus on honors. Debra Holman and James Banning of Colorado State University sought to explore this resource by undertaking a bounded qualitative meta-study of such abstracts using document analysis. Three…

Inquiry-based learning [IBL] enhances students' critical thinking abilities and help students to act as a scientist through using scientific method while learning. Specifically, inquiry as a teaching approach has been defined in many ways, the most important one is referred to nature of constructing knowledge while the individuals possess a…

In this article the author reviews and discusses John Hattie's book "Visible Learning". In this book Hattie presents the results of a meta-meta-analysis on the conditions of successful teaching and learning in schools. Hattie's work is based on more than 800 meta-analyses, and these meta-analyses are substantiated by more than 50 000…

This paper presents a review of distance education literature to describe the status thereof and to identify gaps and priority areas in distance education research based on a validated classification of research areas. The articles (N = 695) published in five prominent distance education journals between 2000 and 2008 were reviewed for this study.…

This meta-analysis addresses whether achievement goal researchers are using different labels for the same constructs or putting the same labels on different constructs. We systematically examined whether conceptual and methodological differences in the measurement of achievement goals moderated achievement goal intercorrelations and relationships…

Federal standards established in 1997 allow respondents to select multiple-race categories. These new standards changed the single-race subgroup definitions that the government has required since 1977. Meta-analysis, research on long-term assessment trends, and other research involving historical comparisons must account for the definitional…

The reanalysis of data to answer the original research question with better statistical techniques or to answer new questions with old data is not uncommon in quantitative studies. Meta analysis and research syntheses have increased with the increase in research using similar statistical analyses, refinements of analytical techniques, and the…

A comprehensive review of research was conducted on teaching science to students with significant cognitive disabilities. Guidelines from the National Science Education Standards were used to identify categories of studies based on the strands of science. A total of 11 studies were identified from the 20 years of literature searched. In general,…

Presents a classification system for developmental psychology that was constructed by means of a survey of articles published in the journals "Child Development" and "Developmental Psychology" in 1969 and 1987. The survey found that eight empirical questions encompassed the full range of empirical interests expressed by…

Explores how magazine type has been defined and on what criteria categories of magazines have been based in communication research. Observes 4 definition strategies in 223 research reports published between 1977 and 1991. Critiques them on their apparent ability to meet five generally accepted standards for the usefulness of scientifically…

This meta-analysis summarizes teaching effectiveness studies of the past decade and investigates the role of theory and research design in disentangling results. Compared to past analyses based on the process-product model, a framework based on cognitive models of teaching and learning proved useful in analyzing studies and accounting for…
