A support environment for learning by describing problem map

A learner who can solve a problem cannot always understand the problem adequately. In order to deeply understand a problem, it is effective that he/she poses problems which can be solved by the solution method of the problem. Moreover after solving and posing problems, it is important for him/her to consider and indicate relations between the problems solved or posed by him/her. In order to let the learner think about the relations, the authors propose a support environment for learning by describing "problem map". The "problem map" is a kind of semantic network where a node is a problem and a link describes relations between two problems. The authors are developing a support environment for describing a problem map in arithmetic learning. The environment cannot only provide learners with workspace to describe problem map, but also feedback based on diagnosis of the described problem map. Additionally, the problem map can be used as a structured problem source for adaptive Web-based problem practice which is generated based on the problem map.
