In September 2002, Salter's Nuffield Advanced Biology ("SNAB") began a three year pilot phase in schools, representing the first major innovation in UK biology education since the 1970s. One part of the AS level coursework was a report on an "Issue of Biological Interest". This could be based on an actual visit outside school…

This study reviews 26 meta-analyses in mental retardation in terms of selected hypotheses, sampling information, representative characteristics of the review, analysis of primary studies, interpretation of results, and reporting of the integrative view. Results indicate a wide variation in the amount of reported data similar to other analyses of…

This article proposes a set of criteria for reporting meta-analyses of topics in learning disabilities. Application of the criteria to examples of published meta-analyses reveals the wide variation in amount of reported data, which could influence the summative results of meta-analyses and subsequent judgment of face validity.

"Positive Action," a K-12 program, aims to promote character development, academic achievement, and social-emotional skills and to reduce disruptive and problem behavior. The program is based on the philosophy that you feel good about yourself when you think and do positive actions, and there is always a positive way to do everything.…

The manner in which results and methods are reported influences the ability of the synthesis of prior studies for planning new evaluations. Confidence ratings, coding conventions, and supplemental evidence can partially overcome the difficulties. Planners must acknowledge the influence of their own judgement in using prior research.

An analysis of 41 recently published articles in the "American Journal on Mental Retardation" and the "Journal of Mental Deficiency Research" found a higher than expected probability of Type I research errors, suggesting that approximately 20 percent of the statistically significant results may be erroneous.

During the 2009-2010 school year, Marzano Research Laboratory (MRL) was commissioned by Promethean Ltd. to conduct a second year evaluation study of the effects of Promethean ActivClassroom on student academic achievement. This report describes the findings from the second year study along with aggregate findings from the first and second year…

This paper focuses on transition programs for youth to postsecondary education, broadly considered. It addresses the following questions: (1) What models or programs of transition exist? (2) On what basis can we say one transition program is more effective than another? In other words, how is successful transition defined? (3) How are…

Most studies of mail survey methodology focus on specific design elements, but several major reviews of research have attempted to synthesize the findings of independent empirical studies. This study examined the review articles for what they have to say about factors influencing response rates and for their methodology. A literature review…

Some of the frustrations inherent in trying to incorporate qualifications of statistical results into meta-analysis are reviewed, and some solutions are proposed to prevent the loss of information in meta-analytic reports. The validity of a meta-analysis depends on several factors, including the: thoroughness of the literature search; selection of…

Subjected 81 research studies on Ivey's (1971) microcounseling program to a comprehensive meta-analysis, assessing the relation between effect size and the sampling distribution of several important methodological and substantive characteristics. Results suggest that the microcounseling program is educationally effective for teaching simple,…

A review and meta-analysis were made of placebo control groups in educational experiments. In all, 125 studies were clustered into procedures that included (1) explicit manipulation of attentional elements; (2) explicit description of the placebo activity plus implied reference to attention; and (3) exclusive reference to the activity. (SLD)

This meta-analysis examined effects from 126 studies that used organizational development (OD) interventions to modify satisfaction and other attitudes. Multi-faceted interventions were found to be more effective in modifying satisfaction and attitudes than were OD interventions that used a single technique. Team building and lab training were the…

Guidelines are offered that make it more likely that high-quality information will be extracted and coded from primary research reports in meta-analyses. It is also noted that the methodology of meta-analysis results in pressure to change the type of information that appears in primary research reports. (SLD)

Disclosing information, thoughts, and feelings about personal and meaningful topics (experimental disclosure) is purported to have various health and psychological consequences (e.g., J.W. Pennebaker, 1993). Although the results of 2 small meta-analyses (P. G. Frisina, J. C. Borod, & S. J. Lepore, 2004; J. M. Smyth, 1998) suggest that experimental…
