In the Fourth Edition of Action Research, author Ernest T. Stringer provides clear guidelines to enable novice practitioner researchers to move comfortably through a process of inquiry that provides effective solutions to problems in the work and lives of those participating in the research. The Fourth Edition provides a simple but highly effective model for approaching action research; Look: building a picture and gathering information, Think: interpreting and explaining, and Act: resolving issues and problems. "Biographical Bulletins" punctuate the text to clarify meaning and to increase understanding of relevant facets of research processes. This best-selling text is appropriate for educational, business, health, and social work settings. New to this edition: a new chapter on using social media to enhance action research processes; an extended description of online sites related to action research; major additions that strengthen the theoretical foundations of action research; and an extended discussion of the literature on action research.
