## Schoenfeld's Schema

Based on the research on learning in mathematics, Alan Schoenfeld presents the following theoretical frame characterizing competencies in problem-solving domains:

### I. The knowledge base

### II. Problem solving strategies

For example: analogy, auxiliary elements, decomposing and recombining, induction, specialization, variation, working backwards (See Polya)

### III. Monitoring and control (Metacognition)

Knowing how and when to use resources and strategies effectively and efficiently

- What am I doing?
- Why am I doing it?
- How does it help me?

### IV. Beliefs and affects

Typical student beliefs about the nature of mathematics

- Mathematics problems have one and only one right answer.
- There is only one correct way to solve any mathematics problem -- usually the rule the teacher has most recently demonstrated to the class.
- Ordinary students cannot expect to understand mathematics; they expect simply to memorize it, and apply what they have learned mechanically and without understanding.
- Mathematics is a solitary activity, done by individuals in isolation.
- Students who have understood the mathematics they have studied will be able to solve any assigned problem in five minutes or less.
- The mathematics learned in school has little or nothing to do with the real world.
- Formal proof is irrelevant to processes of discovery or invention.

### V. Practices

Becoming a good mathematical problem solver -- becoming a good thinker in any domain -- may be as much a matter of acquiring the habits and dispositions of interpretation and sense-making as of acquiring any particular set of skills, strategies, or knowledge. If this is so, we may do well to conceive of mathematics education less as an instructional process (in the traditional sense of teaching specific, well-defined skills or items of knowledge), than as a socialization process.
