The Comprehensive School Mathematics Program (CSMP) is a program of CEMREL, Inc., one of the national educational laboratories, and was funded by the National Institute of Education (NIE). Its major purpose is the development of curriculum materials for kindergarten through grade 6. This document describes non-test data collected from classes tested in spring 1982. Information regarding program implementation, teacher experiences and training, and teacher attitudes is presented. Questions on surveys were responded to and returned by 22 CSMP teachers and 26 non-CSMP teachers. It was found that both groups supplemented instruction, but with differences in what was supplemented. More CSMP instructors included basic operations or computation exercises, using whole numbers, fractions, decimals, geometry, metrics, and percent. Non-CSMP teachers supplemented over a broader array of topics, including "enrichment" material. Analysis also indicated that CSMP teachers tended to follow lesson plans in great detail, view the lessons as challenging for most pupils, view mathematics class as having a more enjoyable atmosphere, view instruction as creative activity-oriented, and regard mathematics as one of the easier subjects to teach.
