In evaluating the effectiveness of a supplementary center for early childhood education it was hypothesized that a nongraded organizational structure would allow for an orderly and meaningful transition from preschooler type play activities to the more formalized learning of the primary age child. It was also believed that a school's primary objective is the building of a healthy self-concept in every child. The study called for the use of interview data, observational data, and interview questionnaires. The data indicated that teachers felt the program did provide an opportunity for the staff to achieve a greater understanding of the developmental needs of individual children, and enabled them to identify potential problem situations, as well as evaluate childrens' progress. Teachers also reported that the program helped children to develop a positive self-concept, especially the older children, who developed good peer relationships and experienced success. Teachers expressed concern that the program did not allow enough time to work with the individual young child. They felt that the greatest variation in ability, interest, and maturity occurred between the 5 and 6-year-olds. [Not available in hard copy due to marginal legibility of original document]. (JF)
