An Empirically Derived Hierarchy of Intraconcept Relationships: Rational Number Multiplication.
Causey, Matthew; Underhill, Robert G.
The purposes of this study were: (1) to develop a skills hierarchy for rational number multiplication using modified intraconcept analysis procedures developed by Uprichard and Phillips in two preview studies, and (2) to evaluate and modify the hierarchy using the Walbesser technique (AAAS) and pattern analysis. Subskills were delineated from two points of view: mathematical and psychological. Alternative forms of an instrument evaluating the performances on 34 identified subtasks were administered to 225 subjects in grades 5, 6, and 7. The final hierarchy, implications, and hierarchy development strategies are discussed. (Author/MP)
