It was a study on thirty-year old persons who had been studied as infants, children and adolescents. Mac Farlane found it surprising that many of the thirty-year olds remembered all of their teachers and many recalled teachers who were especially important to them as the ones who simultaneously respected their feeling, excited. Their interests and elected a maximum performance from them. He advises that with all the variety in the pupils the teachers should have to reach all the pupils. If he cannot do this he should not take up the teaching profession. In brief, we can say that teachers who are competent and emotionally mature make the total school atmosphere full of pleasurable learning experiences for the pupils. On the other hand, the important and maladjusted teacher spoils the school atmosphere.
