The National Science Foundation (NSF) Act of 1950 (as amended) authorizes and directs the foundation to initiate and support: basic research; programs to strengthen the research potential; and science, mathematics, and engineering education programs at all levels. The Division of Teacher Preparation and Enhancement supports model preservice and inservice teacher education programs, the creation of networks that provide support for teachers who are attempting to implement innovative science and mathematics programs, and a program of teacher awards. Descriptions are given of the objectives and scope of three foundation programs: teacher preparation, teacher enhancement, and science and mathematics education networks. This document provides the basic information needed to plan, develop, and submit a formal proposal for NSF grant support for each of these programs. It also provides information on how proposals are evaluated for acceptance or rejection. The appendices contain sample proposal forms with instructions for completing them. (JD)
