Data from the Joint Council on Economic Education's National Assessment of Economic Education (NAEE) Survey, gathered during the 1986-87 school year, provide material for a large-sample study of a broad variety of determinants of economic understanding and attitudes at the precollege level. The NAEE Survey, consisting of four questionnaires, correlates student economic achievement test scores with other student and teacher characteristics data. Direct matchings are available for student scores, student characteristics, and teacher characteristics. Using traditional "production function" analysis, the results indicate that in terms of attitudes about pedagogy, the student/teacher mismatch is a significant determinant of lower scores. Positive teacher attitudes about teaching economics were also found to play a significant role in the achievement of higher test scores. The construction of course content and method, the development of mandated economic education programs, and the assignment of teachers should be done with the recognition that student/teacher interdependencies may affect program outcomes. A 17-item bibliography is included. (JB)
