Kit-Build External Expression of Problem Solving Process in Physics Learning

Diagnosis of errors in problem solving process is very important to support learner's problem solving exercise. Although externalization of the problem solving process by a learner is a promising way to realize the diagnosis, this task is hard for a learner and it is very difficult to interpret the expression automatically for a computer system. In this research, we pay special attention to Kit-Build method to help this task. The expression made by the learner is diagnosed by comparing the ideal one, and the differences are targets of learning support. We have design and implemented a learning environment where a learner expresses his/her problem solving process with the provided parts and the expression is diagnosed. In this paper, results of a preliminary use of this environment are also reported.
