About Learning with Examples

The general culture of the math classroom in the United States is that errors are this taboo thing that are meant to be gotten rid of as soon as they're made. We're changing that and making the error the focal point of the instruction. We're giving the students a chance to engage with errors without the stigma of it having been their own error. The goal is for students to realize that errors can be a productive part of the learning process, and that by making errors in the classroom, it doesn't mean a student is “not a math person,” but that making mistakes is all part of the process and leads us to become better math learners.

The Approach

Research shows that students often enter a math class holding misconceptions that could derail new learning. Teachers, then, need to identify and target misconceptions and build up accurate conceptual knowledge, all while providing students with instruction on the procedural skills that are required by the standards and by standardized testing.

Studies show that when students engage with both correct and incorrect worked examples and explain the associated mathematics, real progress occurs to help dislodge sometimes stubborn misconceptions.

Learning via Self-Explanation

Self-explanation means explaining information to oneself as one reads, solves problems, or attempts to learn. When individuals self-explain, they integrate knowledge (from prior knowledge and/or instruction), infer to fill their knowledge gaps, and make explicit new knowledge and connections. This is all beneficial for learning.

Explaining Correct Solutions

In some exercises, students are told that the solution is correct and are asked to explain why it is correct. Research suggests it is important to require students to explain not only what was done in the example but also why it was correct. This encourages students to go beyond procedural explanations (e.g., "It's right because he divided both sides by 3") to produce more principle-based, conceptual explanations leading to improved conceptual understanding.

Learning via Explanation of Incorrect Solutions

In half of the exercises, students receive an incorrect problem solution and are asked to explain why it is incorrect. This type of activity is believed to improve learning because it helps students to reject their own similar, incorrect procedures. The idea that errors can be effective learning tools is not new: Studies show that asking students to explain both incorrect and correct solutions leads to greater learning. Worked examples can also help motivate students, especially those who are less proficient in math.
