In 1994, the DeWitt Wallace-Reader's Digest Fund made a commitment to school-age care by launching the MOST Initiative--a $6.5 million, multi-year project aimed at systemic community-based change to improve the quality and availability of out-of-school time for children in three cities: Boston, Chicago, and Seattle. The MOST Initiative was designed in partnership with the National Institute on Out-of-School Time (NIOST) (formerly the School-Age Child Care Project) at the Wellesley College Center for Research on Women. The initiative recognized the importance of technology as a tool for: (1) facilitating communication within the collaboration and (2) disseminating information on both local levels (to parents, children, and community programs) and on national levels (to government agencies, media, policy makers, and advocacy organizations). This paper presents a case study of the various ways that technology has been used by the MOST Initiative. The paper discusses details that show how NIOST and the three MOST cities increasingly used technology to implement their action plans and offers suggestions on how other communities can use technology to develop similar networks that support out-of-school activities. The paper's appendices contain a listing of national technology resources relevant to the issue of children's out-of-school time and descriptions of the three MOST Web sites. (LPP)
