This book contains a collection of principles, methods, and strategies useful in the planning, design, and evaluation of studies in education and the behavioral sciences. It is not a technical, detailed study, but an overview, a summary of alternatives, an exhibit of models, and a listing of strengths and weaknesses, useful as a checking and comparing aid for researchers. Because only highlights, outlines, and essentials to achieve emphasis, clarity, and brevity are presented, the user should supplement this document with more complete information from other qualified sources. The guide contains sections on common errors; planning research and evaluation studies; research designs, methods, and strategies; instrumentation and measurement; statistical techniques and the analysis of data; and criteria and guidelines for planning, preparing, writing, and evaluating the research proposal, report, thesis, or article. Coverage includes historical, descriptive, developmental, case and field study, correlational, causal-comparative, true experimental, quasi-experimental, and action research. Author and subject indexes and statistical tables for significance levels are provided. (DG)
