Validation the Measures of Self-Directed Learning: Evidence from Confirmatory Factor Analysis and Multidimensional Item Response Analysis
This research aims to validate the measures Self-Directed Learning (SDL) model for technical college students by using confirmatory factor analysis and multidimensional item response analysis. The model was developed based on the theories by Guglielmino (1977), Rogers (1983) and Cross (1981). The sample for the study included 1, 563 students from technical colleges affiliated with the Office of the Vocational Education Commission of Thailand. The instrument employed for the study was four-option situation evaluation. Data were analyzed through the methods of means, standard deviation, confirmatory factor analysis, and multidimensional item response analysis. The results were: 1) Confirmatory factor analysis: items were suitable for the SDL mode(factor loading ranged from .00 and .63) l. 2) Multidimensional item response analysis: items were suitable for the SDL model as well(the OUTFIT MNSQ ranged from .95 to 1.05, and the INFIT MNSQ ranged from .96 to 1.05). The study concludes that the measures of SDL model employed for technical college students of Thailand were valid.
