In response to the need of Adult Basic Education (ABE) practitioners for means of disseminating information concerning new ideas and practices in their field (particularly the results of "309 Projects" funded under Title III of the Amendments to the Elementary and Secondary Education Act of 1966), The Iowa Model was developed in which the disseminator is the Department of Public Instruction (DPI) working through the "309 Project Directors." The model satisfies the demand for accountability by building in a rationale that emphasizes planning on the basis of local needs, constructing rationales for individual proposals, field testing of innovations, and dissemination of the outcomes. Also involved in each of the three phases of the model (Planning, Testing, and Dissemination) are various information systems, particularly the Educational Resources Information Center (ERIC) through its Clearinghouses on Career Education and Adult Education. In Phase I a search of the literature is conducted, rationale developed, a proposal written and submitted to the DPI for funding. Phase II involves the carrying out of activities described in the proposal, culminating in the design of new practices and materials based on results of field tests. An important element is the establishment of a communications network among project directors. Phase III is a 2-pronged approach to dissemination (1) utilizing the informal network of project directors and (2) utilizing the user networks of the Clearinghouses. Focus is on three dissemination approaches: impersonal communication and personal communication from the DPI, through the project directors, to the practitioners, and such communication between these groups and the Clearinghouses. Possible dissemination media include radio, television, local access cable television, newspapers, newsletters, professional journals, brochures, personal sources, telephone, consultants, Telenet, workshops, conferences, and college courses.
