This is the final report of the Oregon System in Mathematics Education (OSME), a project to improve mathematics education learning in Oregon. OSME in-service projects for teachers provided "hands-on" workshops for teachers at both the elementary and secondary level, and helped Oregon schools and colleges establish 24 local mathematics resource centers. The OSME program tried, in a flexible, decentralized way, to strengthen the abilities of existing institutions and instructors to meet the needs and solve the problems of mathematics education. Sections included in the report are: (1) a history and outline of the project; (2) an acronym guide; (3) sample workshop activities and teacher views; (4) projects for nurturing leadership and supplementing higher education; (5) a report on Students and Computers; (6) OSME communications activities; (7) a report on evaluation of the program; (8) listings of OSME members, staff, projects, and their leaders; and (9) a selective bibliography of documents pertaining to OSME.
