Self-regulated learners are aware of their knowledge and skills and proactive in learning. They view learning as a controllable process and accept more responsibility for the results of this process. The research described in this article proposes, implements, and evaluates an ePortfolio-based self-regulated learning model. An ePortfolio system was developed based on self-regulated learning theories. This ePortfolio system was used in designing a learning model for fostering self-regulated learning in higher education. Two surveys were conducted with the Motivated Strategies for Learning Questionnaire at the beginning and at the end of the courses. The differences in Motivated Strategies for Learning Questionnaire scales between pre-test and post-test, or control group and experimental group were evaluated. The trace data of learning activity were also analyzed to evaluate the effects of the learning model on students' self-regulated learning. The results show that students implemented self-regulated learning processes, and their intrinsic goal orientation, metacognitive self-regulation, effort regulation, elaboration, rehearsal, and critical thinking improved after applying ePortfolio-based learning model in the courses. In conclusion, the ePortfolio system and the proposed learning model had positive effects on students' self-regulated learning skills.

Self-regulated learning (SRL) has positive effects on learners' success in and beyond school, and it may be fostered by technology enhanced learning environments, especially ePortfolio platform. However, the lack of explicit technological models leads to challenges in fostering SRL, such as capturing and sharing SRL principles, creating a platform for SRL's processes implementation. The purpose of this research is to propose an ontological model and use it to design an ePortfolio system to promote SRL. We used ontologies to represent an integrated model that consists of ePortfolio model, competency model and SRL model. Based on this model, we implemented the ePortfolio system and used it for the first experiments at Hoa Sen University. The results indicate that students had a positive reaction to the ePortfolio system, and the system affected students' achievement and SRL positively.
