The Junior High School Mathematics Consortium was a project in cooperative curriculum development involving 20 Alberta, Canada school systems. The project materials were developed and revised according to performance objectives developed by the Edmonton Public School Board, and the program unit booklets were developed cooperatively by ten school systems. The purpose of the evaluation project was to evaluate the mathematical appropriateness of the Junior High Mathematics Program course objectives, and the suitability of the support materials in assisting teachers in reaching these objectives. Data were collected through examinations, interviews, and questionnaires administered to 37 volunteer pilot schools throughout the consortium member systems. The results indicated that the course objectives were mathematically appropriate and that the support materials were suitable for the designed purposes. It was recommended that the program should be authorized by the Alberta Department of Education; but that further study should be made of the program's suitability for slow learners, and that the additional components in the revised program (laboratories, transparency masters, applications, history, basic skills supplement) should be evaluated.
