Increases in Test Scores as a Function of Material Rewards.
Tuinman, J. Jaap; And Others
From the entire population (N=341) of grades 7 and 8 in a rural Indiana junior high school, 160 subjects were randomly selected and assigned to the experimental and the control groups. Form A of the Nelson Reading Test was administered twice with a 4-week interval. While the control group was told only that the post-test was given to measure how much they had learned since the last testing, the experimental group was told that those making any performance improvement would win material rewards. Those making the most increase received one of six transistor radios; others received a university sweatshirt or a 25-cent candy bar. Results were analyzed using analysis of covariance. Two major dependent variables were the total number correct (NC) and the total number of items attempted (NA). Post-test means were adjusted for pretest differences between the two groups. The effect of the reward treatment was found to be significant in all instances on the NC variable (p<.01) and on the NA variable (p<.001). Results for the vocabulary and comprehension subtest were also reported. It was indicated that the experimental group outperformed the control group by more than 3 months in total means. Tables and references are included. (AW)
