Developing Ratio and Proportion Schemes: A Story of a Fifth Grader.
Lo, Jane-Jane; Watanabe, Tad
Journal for Research in Mathematics Education, v28 n2 p216-36 Mar 1997
Studies the developmental process of how the concepts of ratio and proportion do not develop in isolation, but rather are part of the individual's multiplicative conceptual field, which includes other concepts such as multiplication, division, and rational numbers. Follows one fifth-grade student as he attempts to schematize his trial-and-error-based method. (AIM)
