Social Work Theory and Methods [PDF ebook] 
The Essentials

This gateway text lays the foundations for a thorough knowledge of the theory and methods that social workers need. Pulling together the work of a team of experts, this book uses the innovative "theorizing practice" approach, rather than the traditional "applying theory to practice" approach, thereby providing a much more satisfactory basis for understanding the relationship between theory and practice and making it easier for practitioners to employ theory in practice.Part I sets the scene by examining the relationship between theory and practice, how research can be used to inform practice and the important role of policy and organizational factors. Part II provides 14 chapters, each exploring a different theoretical approach. All in all, this book provides the ideal introduction to using social work theory and methods in practice.
