The Compound Area of Quadrilaterals and Triangles: A Worked Example Based Learning Design

Complex yet hierarchical mathematical material in fact does not mean that the process of schema acquisition and accommodation long-term memory is easy. For an instance, year seven students learn to solve problems related compound area quadrilaterals triangles. This problem may be categorized as a well-structured problem, therefore, it might procedurally obvious reach solution, for those who have possessed sufficient prior knowledge aspects shapes. study aims discuss instructional strategy novices when learning like these. Based on cognitive load theory, worked example could applied effectively novices. The design must presented such way minimize extraneous load. composite shapes quadrilateral triangles challenging described integrated format avoid split attention effect. paper shows how this can done by using techniques, (1) number sequences solution steps; (2) different colors prompting resource; (3) less wording, more procedure application; (4) consistency layout within overall material. In order apply these, designers should follow ADD steps, Analyze content, arrange them accordingly; Design one example, evaluate its accuracy niche; Develop into several pairs. Two with paired been successfully developed declare valid. Eventually, suggested comprehensive consideration designing contain pictures reflects use their resource during learning.
