Helping Students Evaluate the Validity of a Research Study / George A. Morgan and Jeffrey A. Gliner.

Students often have difficulty in evaluating the validity of a study. A conceptually and linguistically meaningful framework for evaluating research studies is proposed that is based on the discussion of internal and external validity of T. D. Cook and D. T. Campbell (1979). The proposal includes si...

520 |a Students often have difficulty in evaluating the validity of a study. A conceptually and linguistically meaningful framework for evaluating research studies is proposed that is based on the discussion of internal and external validity of T. D. Cook and D. T. Campbell (1979). The proposal includes six key dimensions, three related to internal validity (instrument reliability and statistics, equivalence of participant characteristics, and control of experience/environment variables) and three related to external validity (operations and instrument validity, population validity, and ecological validity). How to use these scales is illustrated through a study by J. A. Gliner and P. Sample (1996) in which the purpose was to increase the quality of life for people with developmental disabilities. Students have been able to make sophisticated evaluations of studies using rating scales based on these six dimensions, and this method of teaching validity helps students become better consumers of research. (Contains three figures and seven references.) (Author/SLD)
