This sourcebook and report describes the results of the Alternative Teacher Preparation Institute for Secondary Foreign Language, Mathematics, and Science Teachers at Georgia State University, and offers a plan to implement an alternative graduate level teacher preparation program, the Teacher Education Environments in Mathematics and Science (TEEMS) project. The underlying framework for the new program is based on reflective and constructivist models of learning; it will be planned holistically by college professors, secondary classroom teachers, and supervisors. The TEEMS project is designed to prepare a new cadre of mathematics and science teachers for Georgia's middle and secondary schools. Materials in the sourcebook are organized into the following sections: (1) The Alternative Teacher Preparation Proposal; (2) The Alternative Teacher Preparation Curriculum; (3) The Nature of Alternative Teacher Preparation; (4) Status and Perceptions of Alternatively Prepared Teachers; (5) Attitudes of Alternatively Prepared Teachers; (6) Concerns of Alternatively Prepared Teachers; (7) The TEEMS proposal; and (8) the TEEMS Curriculum. An appendix provides recruitment brochures, application forms, and evaluation forms used in the Alternative Teacher Preparation Program. (LL)
