This thesis, the outcome of nearly three years of preparation, including study, development of procedures, trial and observation, was begun in an attempt to answer the following questions: How may original writing among elementary pupils be motivated successfully? Can positive feelings about self be promoted to a measurable degree as a result of emphasizing individual oral and written expression? Although much thinking and evaluating occurred during the three years, the experimentation and results reported here are limited to the work accomplished and findings obtained during the third year. The twenty-six children involved in this study were third-year elementary pupils, whose ages ranged from seven to nine years. During the experimental period, listening, speaking, thinking, and writing were emphasized in the language arts program. A variety of topics provided subjects for written composition. To test the hypothesis that a measurable increase in self concept or self report ratings could be brought about by experiencing feelings of success and acceptance as a result of self-expression in writing, the Piers-Harris Children's Self Concept Scale was administered to two third grade classes, the experimental group and a control group, at the beginning and at the conclusion of an eight-week experimental period. Average reading scores from the Metropolitan Achievement Test, Form F, were available as an index to the ability of the two groups. During the experimental time, a writing topic was presented to the experimental group daily. Questions were used to promote discussion, elicit ideas, and encourage thinking and interest. When the majority of the group members had participated orally, and appeared to be interested and involved, paper was distributed and writing was begun. The writer could choose the form his writing was to take, and a variety of ideas could be derived from the topic presented. The result might be an account of a personal experience, original imaginative writing, rhymed or unrhymed verse, or a factual report. At the conclusion of the eight-week experimental period, self report scores of the two groups were compared. To demonstrate a significant change in score from the initial to the final report, a difference in individual raw scores of ten or more points was required. The raw scores of four subjects in the experimental group, and two subjects in the control group increased by ten or more points. However. the findings of this study indicated no significant differences to the self concepts of children in the experimental group as compared to the self concepts of children in the control group as a result of the writing treatment.
