| This suggestion is contrary to many [[learning_paradigms:constructivism|constructivist]] [[instructional_design:discovery learning]] methods which suggest a learner should try to solve the problem by himself. [[learning_theories:Cognitive load theory]] on the other hand suggests that searching for the problem solution places unnecessary load on the learner's mind preventing him from learning. A worked example will remove the load of searching for a solution and enable easier acquisition of basic steps leading to the solution. | This suggestion is contrary to many [[learning_paradigms:constructivism|constructivist]] [[instructional_design:discovery learning]] methods which suggest a learner should try to solve the problem by himself.

| - | Learners should be presented with a worked example of the procedure they're expected to learn prior to trying to solving a problem which requires that procedure. For example, when teaching learners the formula for calculating roots of a quadratic formula, learners should first be provided with a worked example of using the formula, and then try to solve a problem on their own. | + | Learners should be presented with a worked example of the procedure they're expected to learn **prior to trying to solve a problem** which requires that procedure.
