The Second Edition of Educational Research is an informal and highly readable text that provides students with a clear and in-depth understanding of the different kinds of research—including technology-based—that are used in education today. This text introduces students to the fundamental logic of empirical research and explores the sources of research ideas. Detailed descriptions guide students through the design and implementation of actual research studies with a balanced examination of quantitative, qualitative, and mixed research, serving as one of the book's strongest features. While quantitative research strategies are covered extensively, the text also discusses various qualitative approaches such as ethnography, historical methods, phenomenology, grounded theory, and case studies. This new edition addresses the use of technology in conducting educational research, incorporating links to a database of journal articles, extensive discussion of technologically-based research exercises, and a complete companion website. The authors present detailed, step-by-step coverage of the key elements of research, including sampling techniques, ethical considerations, data collection methods, measurement, judging validity, experimental and non-experimental methods, descriptive and inferential statistics, qualitative data analysis, and report preparation.
