Students' Overuse of Proportionality on Missing-Value Problems: How Numbers May Change Solutions
Van Dooren, Wim; De Bock, Dirk; Evers, Marleen; Verschaffel, Lieven
Journal for Research in Mathematics Education, v40 n2 p187-211 Mar 2009
Previous research has shown that when confronted with missing-value word problems, primary school students strongly tend to use proportional solution approaches, even if these approaches are inappropriate. The authors investigated whether (besides the missing-value formulation of word problems) the numbers appearing in word problems are part of the superficial cues that lead students to (over)use proportionality. (Contains 6 tables and 6 footnotes.)
