ab: 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.
