Abstract
When learners make mistakes in spite of their self-confidence, they often doubt if their answers were really wrong. In such cases, they usually examine how they should have answered and try to promote their understanding of lesson contents. In this paper, such nature that learners originally possess is called selffeedback. In education situations, it is important that teachers help learners' self-feedback to function smoothly. However, no effective methods have ever been appeared as far as we know. Our advanced investigation found that learners did not try to recheck their answer unless they had self-confidence. This paper proposes a CAI system providing a learning environment to encourage self-feedback in learners. The CAI system is based on the idea that learners should not be forced to make any answers without their self-confidence. We carried out our experiments on a math class of first-year students of a junior high school. The results show the effectiveness of our system.
