Based on the self-determination theory, we can promote the learner self- determination ability to affect their learning achievement. This research is different than the traditional on-line platform designed; we used self- determination theory as a learning approach, and design the online platform for students’ self determination. According that, the online-self determination platform has the characteristics, such as: having a learning path for self-determination, strengthening the sense of independence, providing a diagram for cognitive loading theory (CLT), promoting abilities of self-assessment, diagnosing learning situation, using online discussion and interaction to construct a social group.
