A Learning Environment for Problem posing in Simple Arithmetical Word Problem
Akira Nakano, Tsukasa Hirashima, Akira Takeuchi · 2000
Several researchers indicate that to pose arithmetical word problems is an important way to learn arithmetic. However, the problem posing practice actually is not popular. In this paper, we describe an Intelligent Learning Environment which realizes the problem posing practice. In the problem posing practice, the learners pose problems by using the tools provided by the ILE. The ILE has a facility to diagnose the problem posed by the learner. By using the result of the diagnosis, the ILE helps the learner to correct the wrong problem, or provides the next step of problem posing. We used the ILE in three different situations for evaluation. The subjects were elementary school teachers and elementary school students. We report the results of the evaluation, too. In the ILE, the interface was implemented in Java, and the diagnosis module was implemented in Prolog. So it can be used on World Wide Web. The current environment deals with simple arithmetical word problems.
