The purpose of the conference reported in this document was to bring together national leaders in teacher education to disseminate findings and innovations in the reform of elementary teacher preparation in mathematics and science. The proceedings begin with a presentation of invited addresses: "New Curricula in Elementary Mathematics: What Are the Critical Factors?" (Shirley M. Frye); "The Reform of Elementary School Science: The Critical Issues" (Roger W. Bybee); and "The Integration of Content and Pedagogy in Teaching" (Hilda Borko). The proceedings then present 11 project summaries. Papers form 8 panel sessions comprise the main body of the proceedings; panel themes are teacher knowledge issues, special issues in teacher preparation, and institutional coordination issues. The panel session titles are: (1) Developing Teachers' Mathematics and Science Content Knowledge; (2) Developing Teachers' Pedagogical Knowledge; (3) Developing a Cohesive Program; (4) Underrepresented Groups in Mathematics/Science; (5) Technology in Science and Mathematics Education; (6) School and University Collaboration; (7) Promoting University Faculty Development; and (8) Establishing Administrative Support. The document concludes with an ethnographic summary, "An Interpretive Account of a Conference on the Preparation of Elementary Teachers of Science and Mathematics" (Kenneth G. Tobin). Three appendices provide the conference agenda and lists of conference presenters and conference participants. (LL)
