The Colorado Learning Attitudes about Science Survey (CLASS) is a widely used instrument designed to measure student attitudes toward physics and learning physics. Previous research revealed a fairly complex factor structure. In this study, exploratory and confirmatory factor analyses were conducted on data from an undergraduate introductory…

This study examined the construct validity of the Career Locus of Control Scale (CLCS) among diverse urban youth within the United States (N = 308). Confirmatory factor analyses verified two of the three models as acceptable fits. Two new models were also explored. Model 5 (Internality, Luck, and Non-Control), which was one of the new models, was…
