This article describes several features important in the success of using a behavioral model when treating individuals with autism and presents remaining issues to be addressed for improving treatment effectiveness. It urges future research to include strict empirical designs that allow for sound inferences regarding the parameters of treatment…

This introduction to a series of articles on the scaffolding metaphor in learning disabilities research introduces each article and raises two main concerns: the lack of careful delineation of how scaffolding becomes operational in research studies and constraints in the use of scaffolding arising from communication problems.

Discusses the history of evaluation research, focusing on current emphasis on "evidence-based policy." Highlights five issues emerging as relevant: evaluation can be done in many ways, serious doubts exist about the usefulness of the term "evaluation," evaluation is held back by paradigm wars, views of evaluation are…

Using questioning strategies to involve students in actually doing and analyzing experimental design can offer useful insights to instructors and students alike. Describes an interactive exploration of Alka Seltzer. (CCM)

Based on field studies in five East Asian societies, the paper has three research agendas of portraying mass tutorial schools. The first is to depict those similarities and differences between functioning, infrastructure and popularity of East Asian tutorial schools by means of a 3-layered cultural model and six descriptive indicators. The second…

When the editors of The Voice of Evidence in Reading Research, Ms. McCardle and Ms. Chhabra, decided to edit a book and to invite authors to contribute to it, they wanted it to be a book for teachers. As stated in the first chapter, their motivation was to empower teachers to judge research worthiness for themselves. They feel that it is important…

Drawing upon a programme of comparative studies in three European countries, England, France and Denmark, this paper discusses some of the particular issues and problems that can arise in comparative research. It outlines some ways in which the research has attempted to resolve these and to shed light on the complex interplay of factors--personal,…

Traditional reviews and previous meta-analyses of self-concept interventions have underestimated effect sizes by using an implicitly unidimensional perspective that emphasizes global self-concept. In contrast, this research employed a synergistic blend of meta-analysis and multidimensional construct validation to evaluate the impact of…

A Monte Carlo study examined the statistical performance of single sample and bootstrap methods that can be used to test and form confidence interval estimates of indirect effects in two cluster randomized experimental designs. The designs were similar in that they featured random assignment of clusters to one of two treatment conditions and…

This paper details the challenges encountered by authors summarizing evidence from a primary study to describe a treatment's effectiveness using an effect size (ES) estimate. Dilemmas that are encountered, including how to calculate and interpret the pertinent standardized mean difference ES for results from studies of various research designs,…

To test the effectiveness of an online introductory psychology course, we randomly assigned students to a large, traditional course or to an online course from a population of students who indicated that either course type was acceptable using a "waiting list" experimental design. Students in the online course performed better on exams and equally…

There has been a policy shift away from hospital to community in the services of all those with psychiatric disorders, including those with intellectual disability (ID), in the last 50 years. This has been accompanied recently by the growth of assertive outreach services, but these have not been evaluated in ID services. In a randomized controlled…

African American adolescents' perceptions of racism and career self-efficacy relationships are examined. Participants in a southwestern urban high school completed the Multigroup Ethnic Identity Measure, Racism and Life Experiences Scale-Personal and -Group, and career decision and career task self-efficacy scales. Results indicate that…

Background: Approximately 1,100 education journals collectively publish more than 20,000 education research articles each year. Under current practice, no systematic way exists to move the research findings from these studies into the hands of the millions of education practitioners and policymakers in the United States who might use them.…

There has been an increasing emphasis in educational policies, practices and professional development on the capacity of educational leadership to exert a causal impact on student cognitive and non-cognitive outcomes. If the strict criteria of counterfactual causality are adhered to no causal inference could be made about the effects of…
