Employed and retired engineers and scientists are increasingly being recognized as an underused resource for responding to the need to recruit persons to become qualified teachers of science and mathematics in elementary and secondary schools and to enrich the science curriculum. Two strategies predominate to use this resource. To increase the supply of qualified teachers, one strategy is the recruitment by schools of education of scientists and engineers seeking career change while still employed or in preparation for retirement, to enable them to become certified as full time, regular teachers. A variation of this approach, as allowed under the Education Improvement Act of 1984, is for scientists to begin teaching with provisional certification, and obtain full certification within 5 years. The second strategy, used to enrich science curriculum, is to recruit working and retired scientist and engineers, most of whom are not certified as teachers, to volunteer in science and math classrooms or in after-school activities--usually on a part-time or one-time basis. The National Institute for Work and Learning (NIWL) has surveyed a sample of programs using these strategies, which are summarized in this report. Sections include (1) "Introduction"; (2) "Need"; (3) "Special Initiatives"; (4) "Non-Traditional Programs to Provide Teacher Certification"; (5) "Scientists as Volunteers in the Classroom"; and (6) "Conclusions and Recommendations." Appendixes provide lists of programs and contact persons (17 entries). (KR)
