What is educational research? What are its current approaches, methods and methodologies? How should existing literature be reviewed and evaluated critically? What are the key philosophical debates in and on educational research? How should research in education be conducted and how should it be presented? And what is the value of such research? With this extensively revised edition of a much-admired and engaging guide, Jerry Wellington provides clear and constructive answers to these questions, complete with detailed advice on methods such as interviewing, surveys, documentary research and the use of focus groups. Thoroughly overhauled and updated, this edition includes new case studies, helpful 'theory summary' boxes, and a range of activities or 'points to ponder' to foster engagement with current issues. Retaining the clarity and concision of the previous edition, and its approachable and practical style, Jerry Wellington provides an invaluable text for all those engaged in educational research.
