In mathematical problem solving, students may make various errors. In order to draw useful lessons from the errors, and then correct them, we surveyed 24 eighth-grade students` performances in geometrical problem solving according to Casey`s hierarchy of errors. It was found that: 1. Students`` effect can lead to errors at the stage of "comprehension", "strategy selection", and "skills manipulation"; and 2. Students`` geometric schemas also influenced their strategy selection".
