This review analyzes and synthesizes current research on science education with ELLs. Science learning outcomes with ELLs are considered in the context of equitable learning opportunities. Then, theoretical perspectives guiding the research studies reviewed here are explained, and the methodological and other criteria for inclusion of these…

This meta-analysis reviews experimental and quasi-experimental studies in which students learned by constructing, modifying, or viewing node-link diagrams. Following an exhaustive search for studies meeting specified design criteria, 67 standardized mean difference effect sizes were extracted from 55 studies involving 5,818 participants. Students…

Observer disagreement is important because it limits the reliabilities of observational measures. To avoid this limitation, observers should be trained, and criterion-related and intraobserver agreement measures should be used both before and during a study. Several agreement coefficients are examined for their applicability. (Author/BW)

The Coleman Report, Equality of Educational Opportunity (EEOS), and several reanalyses of its data are reviewed. The methodologies and results of several field studies of the effects of school desegregation upon the academic performance of black students are evaluated to determine whether they support the conclusions drawn in the EEOS. (EVH)

This paper analyzes the teaching of reasoning and civility (citizenship) from the historical perspective of psychology. Three perspectives of human rationality--humans as rational, boundedly rational, and collectively rational--have differently defined the learner, the task, the teacher, and educational research. Unwillingness to address humans as…

Available published research on tutoring is reviewed with emphasis on research findings. Field research on long-term programs is examined, followed by a closer scrutiny of specific variables affecting the outcomes of tutoring--variables often examined in short-term projects. Included are problems of methodology and design. (RC)

Six quantitative reviews of the research on student ratings of instructional effectiveness are examined. The disparate conclusions of the reviews are explained by comparing the syntheses at each of five steps in a meta-analysis: specifying inclusion criteria; locating studies; coding study features; calculating study outcomes; and data analysis.…

An integrative and critical review is provided of the guidance available for conducting validity inquiry in the context of performance assessment. Reviewed studies focus on philosophical underpinnings and practical guidelines for conducting validity inquiry. Sections describe the emerging consensus on validity inquiry, components of validity…

In program evaluation and policy analyses, utility supplants rigor as the first and most important criterion in judging literature reviews. Although R. T. Ogawa and B. Malen emphasize rigor, a utilization-focused evaluation emphasizes purpose and audience, both of which affect the conduct of a multivocal literature review. (SLD)

Reviews of multivocal literature are assessments of what can be learned from a given body of literature and assessments of the claims on which that knowledge is based. Methodological rigor is less likely to be a problem in such reviews than is lack of independent judgment. (SLD)

Ways in which scientists and science students respond to anomalous data are analyzed. There are seven distinct ways in which they respond, only one of which is to accept the data and change theories. Factors that influence theory change and implications for science instruction are reviewed. (SLD)

The use of analysis of variance (ANOVA), multivariate analysis of variance (MANOVA), and analysis of covariance (ANCOVA) by educational researchers was studied through review of several prominent research journals. The analyses suggest that researchers rarely verify that validity assumptions are satisfied, and typically use analyses that are…

Examines methods used in analysis of school and home effects in three recently published International Association for the Evaluation of Educational Achievement studies. Results of this examination lead to different results than those found in the original study. (Author/DEP)

Research on the values clarification and moral development approaches to values education is reviewed. The purpose of the research, sample, treatment duration, instrumentation, effects of treatment, internal and external validity problems, major strengths and weaknesses, and confidence in researcher's claims are provided for each study. Further…

Using a framework to review the research, this article evaluates the effectiveness of adjunct questions and objectives in a prose learning setting. The framework proved useful in identifying processes responsible for the effects of the two adjunct aids, in explaining unusual and/or discrepant results, and generating recommendations for future…
