This activities manual describes how to utilize the Curriculum Information Network (CIN), a pilot program in the state of Iowa which acquires and disseminates information on new instructional methods and materials designed by Iowa social studies teachers in grades K-12. Part I describes duties of the local representative at the CIN pilot centers, services provided by the public instruction CIN representative, and formats of the CIN Information Packet. Part II provides flow charts which illustrate how to use the CIN, the sheet for teacher input of locally-designed social studies projects, and the negotiation form for retrieving information about a curriculum or instructional project. Presented in the appendices, which comprise the major portion of the handbook, are definitions of related terms; a description of the ERIC system, what it is and how it works; and names, addresses, and telephone numbers of the field representatives for the Iowa Network for Obtaining Resource Materials for Schools (INFORMS).
