This is a project of the National Council of Teachers of Mathematics (NCTM) designed to assist leaders in mathematics education who conduct in-service programs for teachers. Six conferences were held at sites across the country during the summers of 1986 and 1987. Approximately 25 different 3-member teams consisting of school and college leaders attended each 4-day conference. The teams were selected on the basis of their qualifications and experience in the use of computers to enhance mathematics instruction and on their experience and expectations to conduct in-service programs. The materials in this packet were submitted to NCTM staff members to be used throughout the conferences and to be used as a resource by conference participants when they design in-service programs following the conference. Included are: (1) reference papers for conference presentations; (2) resource papers; (3) sample materials to be used in working with groups of teachers; and (4) sample student materials. (TW)
