Book excerpt: Research Methods for Community Change: A Project-Based Approach, Second Edition is an in-depth review of all of the research methods that communities can use to solve problems, develop their resources, protect their identities, and build power. With an engaging writing style and numerous real world examples, Randy Stoecker shows how to use a project-based research model in the community to: diagnose a community condition; prescribe an intervention for the condition; implement the prescription; and evaluate its impact. At every stage of this model there are research tasks, from needs and assets assessments to process and outcome studies. Readers also learn the importance of involving community members at every stage of the project and in every aspect of the research, making the research part of the community-building process.
