The Critical Role of Knowledge Gain in Improving Diagram Comprehension

• In Event: Learning From Multimedia and Graphs

Abstract

Several studies have shown that students can be taught how to better comprehend diagrams. Some of this research has also shown that diagram instruction increases scientific knowledge--learning how to use diagrams appears to boost science learning. Could the increases in diagram comprehension be, in part, due to increases in scientific knowledge? We gathered data from 168 middle school students using one of two different diagram instruction methods and tested a model in which both pre-intervention diagram scores and a residualized knowledge change score predicted post-intervention diagram scores. Both treatments increased diagram scores, but this effect for Treatment students was partially due to pretest diagram scores, whereas for the Comparison condition it was entirely due to knowledge gain.
