Modeling Children's Understanding of Quantitative Relations in Texts: A Developmental Perspective.
Okamoto, Yukari
Cognition and Instruction, v14 n4 p409-40 1996
Tested three models of children's mathematics word-problem solving based on developmental differences in quantitative conceptual structures: (1) quantitative relations represented as ordered array of mental objects; (2) numbers represented on two tentatively coordinated mental number lines; and (3) numerical operations represented as objects on two well-coordinated rule-governed number lines. Found that the models predicted performance and were internally coherent. (KDFB)
