A total of 105 children (3, 4, and 5 years old) participated in a study to determine the extent to which the experience of attending a mobile classroom for an hour and a half, once a week (32 weeks) contributed to the development of social skills. Since this was one of the first attempts to measure these skills in young children, another objective was to learn as much as possible about the development of these skills. The children were divided into two groups. One watched the daily television program, "Around the Bend," and was visited weekly by a home visitor. The other group watched the program, had home visits and visited a mobile classroom once a week. A task which involved placing model furniture in a model house was selected as the task which would most stimulate the occurrence of behaviors that facilitate the process of learning in group situations. Observers coded children's behavior under six major categories: initiation, request for help or questions, giving help, refusing help, group consciousness, and response to peers. Results gave strong indication that the mobile classroom contributed to the development of social skills assumed important in the learning process within a socially structured environment. Tables and graphs comprise more than half the document. A summary of AEL Early Childhood Education program is available as PS 004 889. (Author/AJ)
