Critical-thinking types among nursing and management undergraduates

Watson and Glaser (1994) developed a short version, Form S, of their long-established Watson-Glaser Critical Thinking Appraisal (WGCTA), as a quickly administered measure of critical thinking. This exploratory study used scores from the five sub-tests in Form S, with samples from two professional schools, nursing (n=233) and management (n=131) undergraduates, to identify the typology of critical-thinking types. Four clusters were identified, using a two-stage clustering procedure, in both samples. Discriminant analyses showed that 96% of participants were correctly classified using cluster membership and scores from the five sub-tests as discriminating variables. Implications and recommendations for education and training in critical thinking are presented as well as recommendations for future research on critical-thinking types.
