Excerpt from Efficiency Arithmetic Primary

The recent movement in testing results in education by means of standard scales and tests has revolutionized methods Of instruction in many Of the subjects. One of its results in the field of arithmetic has been to emphasize the necessity of well planned drill work to secure speed and accuracy in the funda mental processes.

The authors, realizing that these drills should be based upon more accurate experimental data than those which had been previously Obtained, formulated and carried out an experiment to determine the degrees Of difficulty presented by the various facts in each of the processes of addition, subtraction, multi plication and division. The facts in each of these processes were then arranged into three groups: An easy group, a middle group and a difficult group.

When the Exercises for Speed and Accuracy were formulated, each fact was recorded as it was put into a problem, and the most difficult facts were made to occur most frequently. This plan was also followed in preparing the lists of abstract prob lems in addition, subtraction, multiplication and division. The emphasis is thus placed where it is needed.

The ability to select the proper process to solve a problem which is met in a social situation is just as important as the ability to compute correctly. This ability is developed by coming, in contact with a wide variety of concrete problems.
