This article examines the effect of the cultivation of students’ motivation and attitudes toward moral practice and their desire to apply the moral values they have learned to their own lives by improving the content of the junior high school moral class D “The Joy of Living Better.” Children are currently unable to show their “weakness” because they view it in a negative light. In junior high school, students are led to accept their own “weakness” in the “Joy of Living Better” section and develop the will and attitude to live better. In particular, in teaching “The Joy of Living Better,” it is important to realize the goodness of human beings and apply it to one’s own way of life. In this article, to cultivate a desire and attitude to implement the moral values students have learned and apply them to their own lives, we conducted classes on the content of item D, “The Joy of Living Better,” in three classes. The effectiveness of the objectives, presentation of teaching materials, and questioning were analyzed based on the students’ behavior in class and the worksheets, and the classes were found to be improved. The results suggest that this practice is effective in fostering students’ motivation and attitude toward moral practice and their desire to apply the moral values they have learned to their own lives. It is suggested that this practice leads not only to the realization of individuality, such as “one’s own personality,” but also to the realization of one’s unique existence and the pursuit of a noble
life.
