A worked example is not just a pre-worked question that is given to the students. There are several types of worked examples and ways of using them.
Typically, the teacher models how to solve a problem by working through an example on the board. As they are doing so, the teacher should be explaining their thinking at each stage and showing why they make the decisions they make as they go.
Examples of how worked examples can be used include the following.
- A partially solved problem is given to the students to complete, either in pairs or on their own. This is not just filling in boxes in a worksheet – students have to demonstrate their thinking and justify their decisions. The problems should be similar to examples they have already seen and worked on. The level of completion needed should decrease as the student’s ability and confidence increases, then scaffolding or concreteness can fade.
- The teacher and the students work through a problem together with the teacher asking guiding questions.
- A worked problem is presented to the students and they are told it contains an error. The students have to work through the problem to find and correct the error, either in pairs or on their own.
- It is important that examples chosen are carefully selected so that they focus on the particular skill or procedure that is being taught and that they slowly increase in difficulty for the best effect.
