Research Methods in Education and Psychology: Integrating Diversity with Quantitative and Qualitative Approaches
Donna M Mertens not only covers two standard paradigms (postpositivist and interpretive/constructivist) but also explores the new emancipatory paradigm that is inclusive of the perspectives of feminists, ethnic/racial minorities and persons with disabilities.
In each chapter, Donna M Mertens carefully explains a step of the research process through the literature review, research method and analysis to reporting the research. Each chapter opens with examples and lists of topics to consider; contains sample studies to illustrate key ideas; has sequence steps to guide one through the research process; and has a question and answer section to elicit further reflection on the material covered.
