The purpose of this study was to determine whether the use of electric calculators offered an effective remedy for the lack of success and the corresponding negative attitude of the low achiever in mathematics. Two hundred and one low achievers were randomly scheduled into one of five control sections or into one of five experimental sections. Each of the five teachers taught one control and one experimental section. All groups followed the same lesson sequence, with the control groups using only paper and pencil for all calculations and the experimental sections using electronic calculators. Pretests and posttests of mathematical attitude (measured by the NLSMA Attitude Inventory) and of mathematics achievement (measured by the Cooperative Mathematics Test for Grades 7, 8, and 9) were given. Among the findings were significant differences (.05 level) between pretest and posttest mean scores on both attitude and achievement tests for both the experimental and the control group, but no significant differences between posttest mean scores for experimental and control group on achievement and on attitude.
