An interactive and intelligent learning environment for learning by constructing

摘要

This paper described an interactive and intelligent learning environment for search algorithm. In the environment, learners can build search algorithms by combining several parts by direct manipulation. Then, the environment diagnoses the algorithms in order to give feedback. First, the environment judges whether or not the algorithms are adequate. When the algorithms aren't adequate, they are diagnosed with heuristics rules. By using the results of this diagnosis, the environment can give messages to help the learners revise their algorithms. We have implemented the environment. The results of a preliminary experiment are also reported.
