An Evaluation of Intelligent Learning Environment for Problem Posing

In this paper, we describe an Intelligent Learning Environment which realizes the learning by problem posing. In the learning by problem posing, a learner poses problems through the interface provided by the ILE. The ILE has a function to diagnose the problems posed by the learner. By using the results of the diagnosis, the ILE helps the learner to correct wrong problems, or leads her/him in the next step of problem posing. We have developed the ILE. In this paper, we also report an experimental evaluation in an elementary school. By using the result of the experiment, we examined (1) usability of the ILE and (2) effectiveness of the ILE. In the ILE, the interface was implemented in Java, and the diagnosis module was implemented in Prolog. The current environment deals with simple arithmetical word problems solved by an addition or a subtraction.
