Preservice Teachers’ Use of Multiple Representations in Solving Arithmetic Mean Problems. (English)
Sch. Sci. Math. 99, No. 5, 250-57 (1999).
Examines solutions presented by preservice teachers for solving graphical and numerical problems involving the arithmetic mean. Participants presented two methods: algorithmic computation and balancing deviations about the mean. A significant difference was found between science and mathematics preservice teachers in the use of balancing deviations to solve problems, but not in the use of the computational algorithm. (ERIC)
