This study identified five effective self-regulated learning (SRL), investigated the correlation of demographic information and SRL, and measured significant predictor of prior experiences on SRL. Eighty-eight Thai learners participated in the SRL survey, which was adapted from the MSLQ. The findings indicated that Intrinsic Goal and Self-Efficacy were correlated with Cognitive Strategy and Study Management, but Test Anxiety was not significantly related with any component. Multiple regressions indicated that Internet and Hybrid-course experiences were significant predictors of Study Management. The same results indicated that learners who had more Internet experience reported a significantly higher level of Self-Efficacy and Cognitive Strategy. (Contains 6 tables and 2 figures.)
