An Intraconcept Analysis of Rational Number Addition: A Validation Study.
Uprichard, A. Edward; Phillips, E. Ray
A hierarchy for learning to solve different types of addition with fractions problems was hypothesized on the basis of both content analysis and psychological considerations. Problem types were defined according to the relationship of the two denominators to each other (e.g., equal, prime, etc.) Students in grades 4 through 8 were each given 45 additional problems to perform. Papers which were totally correct or totally incorrect were deleted leaving a sample of 200. These papers were analyzed using both the Walbesser Technique and Pattern Analysis. No ordering of the tasks was found to yield acceptable levels for all of the Walbesser ratios (consistency, adequacy, completeness). However, with few exceptions, task comparisons yielded acceptable values on two of the three ratios. The empirically determined sequence was analyzed and seven implications for teaching addition with fractions were determined. (SD)
