Effects of Representation and Organizational Features of Text on Success in Mathematical Problem-Solving.
Blohm, Paul J.; Wiebe, James H.
A study examined the effects of manipulating the representation and organizational features of mathematical problems on students' abilities to solve them. Subjects for the study were 238 high school students who had demonstrated ability in computing percentages in a nonproblem solving format. The data analyzed in the study were student responses to test items varying in their representational (diagrammatic versus verbal) and organizational (pertinent versus extraneous) features. It was found that students' problem solving success was not significantly affected by representing percentage problems diagrammatically, but was powerfully affected by the presence of extraneous organizational features in the test items. The subjects' scores on those items that contained pertinent information only were significantly higher than those scores on items that also contained extraneous information. There was no specific hierarchy of difficulty found on the basis of representation and organization of features. (RL)
