- Abstract
Cognitive load theory is an instructional theory that concern to designing an effective learning strategy based on human cognitive system. Worked example was designed based on this theory. Through worked example, students are presented with examples and similar problem solving tasks. This method is believe to reduce extraneous cognitive load. Recent studies reveals that worked example are highly effective for novices, then further tests are needed on effects of this strategy for experts. To test these, total of 118 junior high school students are asked to solve geometry problems and they measured on procedural skills. This experiment compared two levels of learner prior knowledge (expert vs novice) and two learning strategies (worked example vs problem solving). It can be concluded that prior knowledge plays an important role in the effectiveness of learning strategy. Worked example enhanced procedural skills of novices, but it does not effect on experts. Minimum guidance such as problem solving strategy was more effective for experts. Giving worked example to experts causes redundancy effect and extraneous cognitive load. These findings for educational practice in mathematics suggest teacher to designing effective learning strategy by considered students’ prior knowledge.
