The Teacher’s Influence upon the Development of Attitudes Of all the areas of learning, the most important is the development of attitudes. Emotional reactions as well as logical thought processes affect the behavior of most people. "The burnt child fears the fire" is one instance: another is the rise of dictators like Hitler. Both these examples also point out the fact that attitudes stem from experience. In the one case the experience was direct and impressive: in the other it was indirect and accumulative. The Nazis were filled largely with the speeches they heard and the books they read. The classroom teacher in the elementary school is in a strategic position to influence attitudes. This is true partly because children acquire attitudes from those adults whose words they respect. Another reason, it is true that pupils often study somewhat deeply a subject in school that has only been touched upon at home or has possibly never occurred to them before. To a child who had previously acquired little knowledge of Mexico, his teacher’s method of handling such a unit would greatly affect his attitude toward Mexicans. The media which the teacher can develop healthy attitudes are innumerable. Social studies (with special reference to races, beliefs and nationalities), science matters of health and safety, the very atmosphere of the classroom, these are a few of the fertile fields for the education of proper emotional reactions. However, when children come to school with undesirable attitudes, it is unwise for the teacher to attempt to change their feelings by scolding them. She can achieve the proper effect by helping them obtain constructive experiences. To illustrate, first grade pupils’ afraid of policemen will properly alter their attitudes after a classroom chat with the neighborhood officer in which he explains how he protects them. In the same way, a class of older children can develop attitudes through discussion, research, outside reading and all day trips. Finally, a teacher must constantly evaluate her own attitudes, because her influence can be harmful if she has personal prejudices. This is especially true in respect to controversial issues and questions on which children should be encouraged to reach their own decisions as a result of objective analysis of the facts. The author writes this passage primarily in order to show us that ______.
