An Experimental Investigation of a New Approach to the Teaching of Decimals.
O'Brien, Thomas C.
The purpose of this study was two-fold: (1) to investigate the effects of a new approach for teaching decimals by comparing it with two other commonly used methods with respect to achievement and retention of computational ability in decimals, and (2) to determine those areas of the new approach which seemed to be in need of revision. The study was conducted in 36 sixth grade classes in Roman Catholic parochial schools in Cleveland, Ohio. A treatment x levels design was used, with intact classes randomized across the three treatments and students from each class assigned to three levels according to pre-experiment measures of computational ability. Among the conclusions was that the null hypothesis of no differences between treatment means was rejected at the .05 level for both achievement and rentention scores. Achievement scores of the children in the numeration approach were significantly lower than means of the two other approaches. For retention scores, the mean of children in the numeration approach was significantly lower than that of rule-method children, but not significantly different from that of children using the fraction-numeration approach.
