2. Self-drawn schemas were also helpful.
3. Self-drawn schemas took more time than teacher-provided schemas.
4. Self-drawn schemas had extra burdon for the students.
5. Teacher-provided schemas were more effective than self-drawn schemas.
6. Schemas had similar effects for result unknown, start unknown, and middle
unknown problems.
7. There were significant differences between 3rd graders and 4thgraders in operating
