The Problem-Solving Modes and a Two-Layer Model of Hints in the Intelligent Tutoring System for Minimax Algorithm

As a rule, intelligent tutoring systems offer a learner only one problem-solving mode, i.e., feedback is provided after each solution step. Moreover, system’s hints are ordered on the basis of a degree of informativeness and are delivered to a learner sequentially from the most general to the most specific. The paper presents an approach which provides greater adaptive abilities of intelligent tutoring systems. It supports two modes of problem-solving and uses a two-layer model of hints. Therefore, the learner solves problems in the mode which is the most appropriate for him/her and receives the most suitable hint. The aforementioned approach is being implemented in the intelligent tutoring system for Minimax algorithm at present.
