This project addresses the problem of inadequate mathematics high school teacher staffing and the shortage of mathematics specialists in the elementary school. Regular elementary school teachers interested in becoming certified as high school mathematics teachers, and who had taken at least three college-level mathematics courses, were invited to apply for intensive instruction in high school mathematics (algebra, trigonometry, and analytic geometry). Ten high school mathematics teachers served as tutors for the 40 selected elementary teachers. The three pre-calculus mathematics courses were built around the capability of a programmed calculator. Mathematics achievement tests and the Mathematics Anxiety Rating Scale were administered to participants in September and June, with one test also given in January. For the 29 teachers who completed all tests, almost all mathematics areas showed substantial improvement, and mathematics anxiety decreased significantly. (MNS)
