Psychosocial smoking prevention studies have shown inconsistent results and theory-driven programs have been related to program success. This meta-analysis was used as a judgment tool for resolving these issues by estimating average program effects and investigating the relative efficacy of program types. The present study examined 65 adolescent…

It has long been assumed that schools which were "effective" with respect to one set of outcomes (usually academic performance) were generally more "effective" in relation to others. This article reviews the last three decades of British evidence across a range of affective, social and other non-cognitive outcomes including:…

IDEA and NCLB support the case for including English language learners with disabilities in standards-based reform and school accountability efforts. Few states make statewide data on the participation and performance of English language learners with disabilities publicly available. Therefore, district assessment data on English language learners…

Objectives: This meta-analysis evaluates treatment effects for nonpsychotic major depression during pregnancy and postpartum comparing interventions by type and timing. Methods: Studies for decreasing depressive severity during pregnancy and postpartum applying treatment trials and standardized measures were included. Standardized mean differences…

This article reviews research on the achievement outcomes of mathematics programs for middle and high schools. Study inclusion requirements included use of a randomized or matched control group, a study duration of at least twelve weeks, and equality at pretest. There were 102 qualifying studies, 28 of which used random assignment to treatments.…

The study explores the relative effects of a wide range of variables that influence learning, and whether three methods--content analysis, expert ratings, and meta-analysis--agree on whether and how strongly these variables influence learning, using the educational research literature and an expert survey. The presence of an emergent knowledge…

A study reviewed the effects of the whole language movement. Two forms of analysis were used: meta-analysis, and a simple "vote-counting" procedure. Quantitative studies that compared a whole language and a traditional (or basal reading) approach, published between 1988 and 1993, were selected for analysis. A total of 45 studies were…

In its examination of the place of didactics in Scandinavian curricula, this paper discusses didactics as theory and prescription, at different levels of abstraction, and as scientific discipline. It focuses on the process of curriculum planning and selection in two areas: (1) preparing curriculum programs for teaching and learning nationally and…

Thirteen research syntheses were analyzed to determine the academic, social, and psychological effects upon learners who are gifted and talented of three grouping practices: (1) ability grouping for enrichment; (2) mixed ability cooperative grouping for regular instruction; and (3) grouping for acceleration. It was concluded that the research…

The second of four symposium papers brings together the results of four separate statistical analyses of findings on computer-based instruction (CBI) in 199 comparative studies, of which 32 were conducted in elementary schools, 42 in high schools, 101 in universities and colleges, and 24 in adult education settings. Each was a controlled,…

Educational programs and evaluations which were submitted to the Department of Education's Joint Dissemination Review Panel (JDRP), in order to be named validated programs, were studied to identify program characteristics associated with large versus small effect size. Effect size was calculated for 165 out of 232 submittals reviewed by JDRP from…

The effectiveness of an Education Consolidation Improvement Act Chapter 1 program was studied in a large urban school district. A common problem in evaluating remedial programs is that pretest/posttest achievement gains often indicate the effects of the entire curriculum, rather than those specific to the remedial class. In this district, over…

The first science education digest for 1985 focused on data obtained by use of meta-analysis techniques on research studies of science instruction. Instruction seldom takes place without instructional materials, so this second digest is a companion one containing a discussion of science education research on instructional materials. Data are shown…

Reflecting changes in the focus and methodology of writing research over the past 20 years, this book provides a meta-analysis of studies on teaching approaches and focuses on composition instruction at the elementary, secondary, and college levels. The first chapter of the book examines general studies of the composing process, studies of process…

This ongoing project, conducted in four municipalities in Sweden, is investigating the ways in which schools and teaching are affected by various local communities and the ways in which central directives are transformed into a local educational reality. A diverse range of data have been collected, including demographic data from the…
