Kim Sung-sook et al.: Generalizability Theory

When evaluating humans, the validity of the various methods employed depends on how reliable and generalizable the results are. When measuring the process of taking tests, making observations, or performing tasks, the collected results acquire practical significance as information only when they can be generalized to a certain extent. Generalizability theory is practically applicable when measurement situations are complex, when one wishes to calculate the reliability of scores more carefully, and when making decisions to ensure the reliability of future research. Therefore, generalizability theory, which overcomes the limitations of classical test theory, is considered an essential measurement theory that must be mastered by students majoring in measurement and evaluation. This book serves as an introductory text on generalizability theory, designed to help determine the degree of generalizability of results by considering various situations that may arise during the measurement process. To enable even non-specialists to collect and analyze actual data, the book first summarizes the basic concepts and research models of generalizability theory; second, it explains commonly used design models and analysis processes; and third, it introduces programs and illustrates the analysis process using examples of actual measurement situations. And finally, the practical application areas and limitations of generalizability theory were pointed out.
