| Abstract: | In 2 experiments, Ss studied an animation depicting the operation of a bicycle tire pump or an automobile braking system, along with concurrent oral narration of the steps in the process (concurrent group), successive presentation of animation and narration (by 4 different methods), animation alone, narration alone, or no instruction (control group). On retention tests, the control group performed more poorly than each of the other groups, which did not differ from one another. On problem-solving tests, the concurrent group performed better than each of the other groups, which did not differ from one another. These results are consistent with a dual-coding model in which retention requires the construction of representational connections and problem solving requires the construction of representational and referential connections. An instructional implication is that pictures and words are most effective when they occur contiguously in time or space. (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
