The potential reliability and construct and predictive validity of a 30-item Study Skills Questionnaire (SSQUES) was evaluated for its ability to: (1) predict student performance in a self-paced, individualized, or computer-managed instructional environment, and (2) identify students needing some type of study skills remediation. The study was conducted in the context of the Air Force Advanced Instructional System; subjects were male and female Air Force trainees in four computer-managed instruction courses during a nine-week period. Students evaluated their skills in four areas: reading comprehension, memorization, concentration management, and test taking. The questionnaire demonstrated substantial reliability and construct validity. Predictive validity results supported the power of the SSQUES to predict student achievement and to discriminate between students who would perform well versus poorly. (Author/GK)
