Dana K. Keller and Mary Lou Casadevall-Keller provide readers with a highly accessible introduction to the fundamental concepts of research methods in "The Tao of Research: A Path to Validity". This brief, engaging book approaches the topic of research through an exploration of the issues that threaten validity in the process of knowledge generation. The key features: examines the propositional, ethical, structural, functional, and technical restrictions researchers face; focuses on understanding how these restrictions influence research methods and results; and, makes concepts more accessible through discussions that follow the experiences of three 'guides' - a high school principal, a statewide director of public health, and a sociology professor at a small liberal arts college. "The Tao of Research: A Path to Validity" serves as either a main or supplemental text for courses such as Introduction to Research Methods, Social Research Methods, and Applied Research Methods.
