This report represents the record of project activity which has not already been detailed in the First Milestone Report of October 1974 and the second milestone project, "Exploring Teachers' Centers." The National Institute of Education Group on School Capacity for Problem Solving (GSCPS) has conducted a survey to study grass roots teachers' centers as instances of locally generated and designed attempts to change schooling. A teacher center is defined as a program providing continuing education for practicing teachers (mostly elementary teachers), which aims to be responsive to teachers' own definitions of their continuing learning needs rather than to the imposed agendas of school administrators, college professors, or curriculum committees. This study recommends that the GSCPS bring these several strands of interested people together by establishing a small agnecy that could sustain the informal networking now existent. An exchange for and about teachers' centers should be designed not as a technical assistance agency but as a networking to perform the following functions: (1) collect, write, and circulate information about teachers' centers; (2) set up an information central to receive and respond to requests for information and to make referrals among people interested in teachers' centers; (3) arrange for and subsidize personnel exchanges and meetings among educators experienced in and interested in teachers' centers; and (4) document activities pursuant to the above functions and conduct research about the effects on networking and about teachers' centers as a form of inservice education. (A questionnaire and analysis of replies; a list of teachers' centers; and a report of networking documentation are contained in the appendixes.) (SK)
