A Comparison of Two Methods of Column Addition.
Wheatley, Grayson H.
Speed and accuracy in adding a colunm of one addend numbers directly down a column was compared to adding by looking for combinations which add to ten. Ninety-two fourth-grade subjects learned one of these two methods for one week and then learned the other method the following week. Using timed tests after each treatment, it was found that the Direct method was much faster (p less than .001) and just as accurate as the Tens method. This held for all ability levels. There was a slight preference for the Tens methods after training. The results suggest that a computational procedure which requires less decision making is more efficient. (Author)
