Understanding Educational Research [PDF ebook] 

This book explores educational research in terms of the relationship between epistemology, methodology and practice. Divided into two sections, the first examines the frameworks which underpin the methods educational researchers use. The second looks at a broad spectrum of approaches, including feminist approaches, action research, ethnography and biographical research. The issues covered are central to all within the research community including students undertaking research degrees or research methodology courses.
