The reading process involves the use of words as symbols of meaning. Meaning can be realized in various ways, such as through pictures, objects, odors, and tones. Nevertheless, in reading, meanings are associated with language symbols. Since printed symbols are, so to speak, the tools by which we stimulate thinking processes, these symbols become of particular concern to those interested in facilitating the reading act in any sound way. There are those who feel that vocabulary lists direct teachers of reading toward an unnatural break-down of material used. They indicate that to deal with words in isolation is contrary to a proper emphasis on reading for meaning. The writers are wholly in sympathy with the view that meaning is the heart of the matter and that it cannot receive too much emphasis. However, since individual words are the basis of meaning, vocabulary lists are important. Satisfactory methods of teaching, as well as preparation of reading content, depend upon their use. This will be touched upon in subsequent paragraphs. McKee' has much to say about the theory of social utility. According to this theory, material selected for use in the elementary schools should be chosen because of: (1) the frequency of use which may be expected of it in life situations, (2) the degree to which it is used by many people in life situations, and (3) the cruciality of the need for it when it is called into use. This analysis of the basis of selection of material seems sound for the selection of the words to be taught to elementary school children. The words to be taught first and to the point of automatic response should be the words which the child will need most often, and most crucially. To objectify and clarify the job to be done, a list of the most important words for a given level should be at hand.
