Development and Evaluation of a Teaching Material using a Moral Dilemma Story

It was necessary to evolve an instruction method to raise students morality higher. Therefore, a moral dilemma story based on the theory of Lawrence Kohlbergs stages of moral development was introduced as the instruction method. The purpose of this study was to evaluate a newly developed teaching material using a moral dilemma story and to give suggestions to develop teaching materials. The story, called Urgent email was developed and the lessons were practiced in an elementary school, a secondary school and a university in 2008. As a result, it was clarified that the material was effective to raise their morality development stages higher for the fifth graders of elementary school who were positioned in relatively lower level beforehand. On the other hand, the material was less effective for the junior high school students and the university students, because many of them were positioned in relatively higher level beforehand. In addition, according to the result it was necessary to describe the context of the story roughly so that the judgment of the learners was based not on the description of the story but on their internal morality
