The e-Learning issues have been discussed and investigated recent years. People can learn on the Internet and feel more comfortable. But in the e-Learning environment, we discovered the learners might have some troubles in learning. They may encounter disorientation, cognitive overloading and learner control. Using some teaching methods or strategies from teachers can reduce these problems. So the Learning Management System (LMS) must have some mechanisms to accomplish these purposes. This thesis is trying to design a learning path control mechanisms that can help teachers to achieve their teaching goals and help learner to build their learning paths. The learning path control mechanisms are designed with Pre_Condition and Post_Condition. By using these mechanisms, teachers can control the learner¡¦s studying progress and guide learners to the suitable ways. And solving the issues of designing the learning path control mechanisms and user navigation. These mechanisms proposed conform to the e-Learning specification: The Sharable Content Object Reference Model (SCORM) and used the Learning Object and the Run-Time Environment. Finally, this thesis developed a system not only provide the mechanisms but also help teachers to achieve their teaching goals and learners to establish their learning path.
