The book presents a remarkably low threshold for understanding fundamental methodological questions in empirical research. Its clear structure enables even beginners, who may not have a foundational understanding, to find answers to their own methodological questions. Each chapter begins with a typical methodological question that leads to the core of the chapter. In this way, students are made aware of the applications of various methodological approaches. A second question specifies the methodological question in relation to a content-related application aspect that is interesting from a special education perspective. The well-written text also includes recommendations for further literature specifically related to the addressed problem area. Topics covered include research designs and study plans, sampling and selection procedures, data evaluation, and data analysis.
