This digest makes the case that careful planning of replication can enhance the interpretability of applied research. When results are consistent across several studies, there is a stronger basis for observed relationships than the support that is available within each study by itself, since results that have been replicated are considered more…

This digest offers tips on designing questionnaires and on avoiding common design errors. The following useful suggestions are offered: (1) keep the questionnaire brief and concise; (2) get feedback on the initial list of questions developed; (3) locate personal or confidential questions at the end of the questionnaire; (4) put categories in…

The key ethical standards for authorship of educational research are summarized, drawing on "Uniform Requirements for Manuscripts Submitted to Biomedical Journals" developed by the International Committee of Medical Journal Editors. Adopted by more than 500 scientific and biomedical journals, these standards are effective guidelines for…

Fred N. Kerlinger has been hailed as having contributed to the transformation of the way that behavioral scientists and educators read research reports, design and execute research, and draw conclusions about research. In 1960 he introduced the notion that educational research is fraught with mythology. Three of the research myths that he…

This digest reviews the basic building blocks of a structured interview, points out some of the pitfalls in interviewing, and suggests ways for researchers to avoid these difficulties to produce questions that have the best possibility of generating reliable and accurate data on the topics of interest. The data collection instrument is a document…

Meta-analysis is a collection of systematic techniques for resolving apparent contradictions in research findings. Meta-analysts translate results from different studies to a common metric and statistically explore the relations between study characteristics and findings. Since G. Glass first used the term "meta-analysis" in 1976, it has…

Advances in computer technology are making it possible for educational researchers to use simpler statistical methods to address a wide range of questions with smaller data sets and fewer, and less restrictive, assumptions. This digest introduces computationally intensive statistics, collectively called resampling techniques. Resampling is a…

Most practitioners and researchers support the educational policy direction of increased parent involvement, but few agree about what constitutes effective involvement. This digest, based on a critical evaluation of over 200 research studies, briefly reviews findings from parent involvement research to date, discusses their validity and utility,…

This digest briefly reviews the events that led to the development of the American Indian and Alaska Native Education Research Agenda, the basic assumptions and premises underlying it, and its six priority research areas. In response to pressure from Native organizations and tribes and a subsequent Executive Order, a working group organized by the…

Action research is an approach to professional development and improved student learning in which teachers systematically reflect on their work, seek feedback from colleagues, and make changes in their practice. Several benefits of action research have been cited: (1) teachers investigate their own practice in a new way, looking at what children…
