[[alternative]]An Internet-based Mathematical Problem Solving Environment-the Topic of Trigonometry

[[abstract]]The objective of this research is to design and implement an Internet-based learning environment for middle-school-levelmathematics. The kernel of the environment will be a problemsolver which will allow students to learn critical mathematicalconcepts by doing. In this environment the typical learning activity is a learner-centered problem-solving process. Learners may select any problem from a rich set of built-in problems and proceed with the steps of solving the problem. The environment will provideabundant tools to assist learners. Furthermore, the system will be capable of keeping track of the learner's problem-solving steps so it can determine the correctness of the learner's application of concepts in each step and provide hints or guidance when the learner gets stuck somewhere in the process. Furthermore, this Internet-based learning environment will allow simultaneous accesses of the system by multiple users. When the system fails to provide useful assistance to the learner, he/she may seek help from other users with system-provided communication functions.
