Occasionally, supervising teachers carry their plans around in their heads, but this is not a good example to set. Planning is extremely important, and the supervising teacher and intern should spend time on the subject during the term. It is better to over plan than for the students to have spare time on their hands and become behavior problems. The supervising teacher should have the intern work into the teaching situation gradually by assigning work with individuals who need help, with small groups, with portions of the day's lesson with the entire class, and then with the entire class for the entire period or lesson. The supervising teacher should plan specific times for uninterrupted conferences with the intern.
Frequency is more desirable than length.
From the very beginning, there should be an air of friendly criticism, with the supervising teacher using positive reinforcement whenever possible. Tactfully done, this can be professionally developmental for the intern. During the conferences, the supervising teacher should help the intern look back as well as forward. In discussing those classes already taught, share feelings and ideas so that in planning for the future the intern can capitalize on successful techniques. Maintaining a journal assists both the intern and the supervising teacher.
