Abstract
At a point of contact with the educational intent, children's learning activities have deep relationships to teaching materials. Therefore, it must be said to be a particularly important problem in teaching materials and methods, whether the educational contents of teaching materials can function effectively or not. This paper is intended to find a clue to the solution of this problem by grasping each stage of children's emotional processes caused by a self-made teaching material- "Screen Operetta". By means of "Screen Operetta", a teaching material composed for children's musical appreciation, we attempt to grasp positively each stage of children's emotional processes in these appreciating activities, and to discuss the effectiveness of this teaching material as well.
