Formal Operations and the Ability of Students to Structure Geometric Content.
McDonald, Janet L.
The ability of tenth grade plane geometry students to structure concepts and relationships from a geometry unit on ratio, proportion and similarity was tested. Analysis of cognitive "maps" of the structural relationships possessed by twenty concrete and twenty formal subjects indicated that formal operational subjects structure subject matter content significantly more like subject matter experts and teachers than do concrete operational subjects. Results also showed that the cognitive maps of students more closely approximate those of subject matter experts than those of their own teachers. (Author)
