A Comparison of Initially Teaching Division Employing the Distributive and Greenwood Algorithm with the Aid of a Manipulative Material.
Kratzer, Richard Oren
The purpose of this study was to compare the repeated subtraction method of long division of a partitioning distributive method, both taught by recording manipulation of popsicle sticks. Two instructional units were prepared. Twelve fourth grade classes were used, with six being taught one approach and six using the other. Tests consisting of division examples and of verbal problems were given immediately at the completion of instruction and then repeated four weeks later. Analysis of covariance was used. Results showed no significant difference between methods on achievement of familiar problems, but a significant difference between methods on unfamiliar problems favoring the distributive method group.
