Abstract:
The purposes of this quantitative research were 1) to develop and validate the casual model of blended learning on self-directed learning of undergraduate students and 2) to examine the goodness of fit of a casual model of blended learning on self-directed learning of undergraduate students. The samples consisted of 382 college students from three public universities. Two exogenous variables were 1) instructors experiences and 2) learners experiences while twelve endogenous variables were 1) objectives; 2) assignment; 3) guidance; 4) learning activities; 5) student-student interaction; 6) student-content interaction; 7) student-instructor interaction; 8) resources; 9) feedback; 10) formative evaluation; 11) summative evaluation; and 12) self-directed learning. The research data were collected by the questionnaire. The effect of the blended learning variables on self directed learning was calculated using descriptive statistics, a Pearsons product moment correlation, and a structural equation modeling by LISREL program. The results were as follows: 1. The casual model of blended learning on self-directed learning was valid and fit to the empirical data. The model indicated that the Chi-square goodness of fit test was 28.94 p = 0.98, df = 47, GFI = 0.99, AGFI = 0.98, and RMR = 0.015. The model accounted for 44% of variance in blended learning instruction factors affecting self-directed learning of undergraduate students. 2. Factors affecting undergraduate students self-directed learning were 1) instructors experience; 2) learners experience; 3) objectives; 4) assignments; 5) learning activities; 6) student content interaction; 7) student - instructor interaction; 8) feedback; 9) formative evaluation; and 10) summative evaluation. Three of ten factors had direct effects on self-directed learning whereas seven factors had indirect effects on self-directed learning. The finding was described as follows: Assignment, activities, and objective directly affected on self-directed learning. However, there were no effect of guidance, student student interaction, and resources on students self-directed learning
