Benefits of Knowledge-Based Interactive Learning Environments: A Case in Combinatorics

Solving combinatorics exercises is a difficult task for students because the modeling activity involved is not usual. To help students to train themselves, we have built an AI based computer assisted learning system that gives them a specific framework to solve exercises and teaches them a general problem solving method. In this article we present the benefits of using such a system in a learning process, in relation to standard teaching (as in the classroom)
