Psychometric properties of Watson-Glaser Critical Thinking Appraisal for a sample of education majors.

Psychometric properties of the Watson-Glaser Critical Thinking Appraisal, Form A, were computed for 135 education majors. Analyses of reliability (internal consistency and split-half) and validity (concurrent and predictive) showed that the scale was reliable and valid measuring critical thinking abilities for students majoring in education. The best predictors of the Educational Psychology course grades were the Inference and Deduction subscale scores.
