On the Derivation of Instructional Applications From Cognitive Theories: Commentary on Chandler and Sweller |
| |
Abstract: | In "Cognitive Load Theory and the Format of Instruction," Chandler and Sweller (1991) report a series of experiments that focus on presentation formats that optimize learning from diagrams accompanied by ancillary text. This series of studies continues a line of work in which Sweller and his colleagues (Cooper & Sweller, 1987; Sweller, 1988; Sweller & Cooper, 1985; Tarmizi & Sweller, 1988; Ward & Sweller, 1990) have shown that students who study worked examples perform better than students who actually work the problems. Sweller (1988) proposed cognitive load theory as an explanation of these results, indicating that the critical feature of worked examples is that they appropriately direct attention and impose a relatively light cognitive load. Similarly, other presentation formats that accomplish these goals should also facilitate learning. |
