Evaluation research can assess the value and effectiveness of interventions and innovations involving people. While this has often been on a grand scale, this book focuses on small-scale projects carried out by an individual or small group, typically lasting for weeks or at most a few months, at a local rather than national level. Using limited jargon and featuring integrated, real-world examples, this second edition offers a clear, accessible background to evaluation and prepares you to undertake your own small-scale evaluation research project. Key features include discussion of: • Different approaches to evaluation and how to choose between them • The advantages and disadvantages of randomized controlled trials (RCTs) • Realist evaluation and its increasing importance • The centrality of ethical and political issues • The influence and opportunity of the Internet Tightly focused on the realities of carrying out small-scale evaluation, Small-Scale Evaluation is a highly practical guide covering the needs of both social scientists and others without this background.
