Reducing the Mismatch of Geometry Concept Definitions and Concept Images Held by Pre-Service Teachers
Cunningham, Robert F.; Roberts, Allison
Issues in the Undergraduate Mathematics Preparation of School Teachers, v1 Sep 2010
Twenty-three female elementary pre-service teachers were assessed on their ability to answer questions involving geometry concepts. Despite being given the definitions of the altitude of a triangle and the diagonal of a polygon on the pretest, limited understanding of these concepts was evident. A treatment using both graphic organizer and concept attainment teaching strategies improved performance on the posttest but not to the level required for teachers to supplement textbooks that lack adequate definitions or non-prototypical examples. Careful attention to challenging geometry concepts is needed so that pre-service teachers will be able to provide their students with improved conceptual understanding. (Contains 1 table and 2 figures.)
