Visual and Analytic Strategies in Geometry

We argue that there is an increasing reliance on analytic strategies compared to visuo-spatial strategies, which is related to geometry expertise and not on individual differences in cognitive style. A Visual/Analytic Strategy Test (VAST) was developed to investigate the use of visuo-spatial and analytic strategies in geometry in 30 mathematics teachers and 134 11 th null grade students. Students’ performance in the VAST was also compared to...
