Leading social research methodologists and evaluators address the issues of validity, research design and social experimentation in this first of two volumes inspired by the work of Donald Campbell and sponsored by the American Evaluation Association. The first part of the book focuses on three types of validity: external, construct and statistical. Much attention is given to meta-analysis, statistical testing and effect sizes. The second part is a major critique of Campbell's vision and practice of social experimentation. Contributors review and extend Campbell's ideas, concentrating on their relevance to evaluation and social intervention, and seeking to define an 'experimenting society.'
Leading social research methodologists and evaluators address the issues of validity, research design and social experimentation in this first of two volumes inspired by the work of Donald Campbell and sponsored by the American Evaluation Association. Each chapter is designed to offer readers insight into such issues as validity applied to meta-analysis, subject selection problems in randomized experiments, time-series designs and quasi-experiments, and the logic of ruling out rival hypotheses. Anyone engaged in social research will find this book a thought-provoking and inspiring read for their work.
