This chapter deals mainly with the teacher's share in the lesson to give the student some help in the preparation of lessons he will have to give during his practice in school. The teacher's notes as to the amount of work covered in any given lesson, notes made only to ensure that no time is wasted and no confusion caused by a lapse of memory. The general aim of the course of lessons could be to encourage appreciation, and a special lesson might be devoted to giving the children knowledge of ballad metre and skill in using it. From the previous knowledge of a child some definite part or aspect must be chosen to act as host for the new knowledge which the children are to acquire in the lesson. The necessity of arousing interest has been already discussed, but throughout the preparation a teacher should think what share the class is to take in a lesson.
