This meta-analysis examined the influence of attributes related to the implementation of learning strategy instruction interventions on students' academic performance, and also examined how the attributes related to the method of testing the intervention effects affected the actual effects measured. Using metaregression, we analyzed the…

Attention has been directed toward extended school time as a measure to improve academic achievement. The school year and day length have varied over time and across localities depending on the particular needs of the community. Proponents argue that extending time will have learning and non-academic benefits. Opponents suggest increased time is…

Critical thinking (CT), or the ability to engage in purposeful, self-regulatory judgment, is widely recognized as an important, even essential, skill. This article describes an ongoing meta-analysis that summarizes the available empirical evidence on the impact of instruction on the development and enhancement of critical thinking skills and…

The dominant literature on research synthesis methods has positivist and neo-positivist origins. In recent years, the landscape of research synthesis methods has changed rapidly to become inclusive. This article highlights methodologically inclusive advancements in research synthesis methods. Attention is drawn to insights from interpretive,…

A dozen schemes proposing to classify research questions are surveyed, analyzed, and applied to the understanding and practice of inquiry. The extent to which these schemes account for questions found in educational journals is estimated. Principles and issues are identified to stimulate work on the classification of research questions. (Author/BS)

In this article, research conducted in the United States since 1987 on the effects of homework is summarized. Studies are grouped into four research designs. The authors found that all studies, regardless of type, had design flaws. However, both within and across design types, there was generally consistent evidence for a positive influence of…

Some of the literature related to the area of instructional research, individualized instruction and student aptitude are explored in this article. (DEP)

Issues of reliability and validity in ethnographic design are compared to their counterparts in experimental design. Threats to the credibility of ethnographic research are summarized and categorized. Strategies intended to enhance credibility (study design, data collection, data analysis, and presentation of findings) are incorporated throughout…

A review of research suggests that support for team teaching is not based on empirical evidence. Intensive, systematic investigations are needed before the effectiveness or ineffectiveness of team teaching can be substantiated. (MV)

This study examines the influence of various educational interventions in higher education on students' racial bias. The author reviews studies in four principle domains: multicultural courses, diversity workshops and training, peer-based interventions, and service-based interventions. He pays particular attention to the varied approaches,…

R. T. Ogawa and B. Malen's article does not meet its own recommended standards for rigorous testing and presentation of its own conclusions. Use of the exploratory case study to analyze multivocal literatures is not supported, and the claim of grounded theory to analyze multivocal literatures may be stronger. (SLD)

Alternative designs for educational research are explored to improve the external validity of educational research and broaden its scope to include not only the systematic experiments that identify psychological mechanisms but also representative designs that match the complexity of learning behavior in school. (JH)

The major theme is that better and more productive studies could emerge if media research would move out of its traditional either-internal- or-external validity conflict. (Author/MV)

Two papers respond to an article by P. Atkinson, S. Delamont, and M. Hammersley (1988) critiquing papers by E. Jacob (1987, 1988) on qualitative research traditions. The use of T. Kuhn's concept of "paradigm" and the criticism that the British were not included in the Jacob's study are addressed. (TJH)

This article analyzes 41 studies that evaluated K-12 parent involvement programs in order to assess claims that such programs are an effective means of improving student learning. It examines the characteristics of the parent involvement programs, as well as the research design, data, and analytical techniques used in program evaluation. Our…
