Sections in this report cover: (1) the goals of PCMP, (2) the PCMP and instructional objectives, (3) the curriculum, (4) teachers' professional growth, (5) learning experiences, (6) an evaluation plan, (7) a summary, (8) a bibliography, and (9) four appendices. The first appendix presents some sources from literature that provide research support for PCMP. Appendix B is a list of selected references, Part C is a list of desired student outcomes in mathematics, and the fourth appendix reviews the Pennsylvania Retrieval of Information for Mathematics Education System (PRIMES), a resource for educators to use in developing, implementing, and evaluating mathematics curricula.
