The Priorities in School Mathematics (PRISM) Canada Project was initiated in September 1977 as a companion study to the National Council of Teachers of Mathematics (NCTM) PRISM Project. These twin projects were designed to help provide guidelines and suggestions for curriculum changes during the 1980's. Two instruments were used, a Preferences Survey and a Priorities Survey, and were given to both professional and lay samples. The view of professional preferences looked at content, goals, resources, methods, how much time should be spent on instruction, and calculators. Usually all of these were considered for the following content strands: 1) fractions and decimals; 2) algebra; 3) whole numbers; 4) geometry; 5) probability and statistics; 6) ratio, proportion and percent; 7) problem solving; 8) measurement; and 9) computer literacy. Lay opinion on preferences combines the content strands. The survey considered aspects of both the elementary and secondary curriculum and viewed issues such as student needs, content improvement, teacher education, upgrading activities, general problems, distribution of research funds, and methods of attacking problems. Implications for action highlights seven recommendations found in NCTM's "An Agenda for Action: Recommendations for School Mathematics of the 1980's." The document concludes with comments and criticisms about the survey made by respondents. (MP)
