This pilot study tested the hypothesis that the logical thinking skills of middle-grades students are enhanced by teaching them computer programming using the BASIC programming language. A quasi-experimental design was used with 36 students randomly selected and assigned to one of two treatment groups: 18 students received no instruction in programming (the comparison group) and 18 students received programming instruction for 10 weeks (the experimental group). The Test of Logical Thinking (TOLT) was used as a pretest and posttest measure of logical thinking skills. The posttest scores were analyzed using analysis of covariance procedures with the pretest TOLT scores as the covariate. The results indicate no significant differences in level of logical thought at the .10 level of significance (F=2.52; p=.12), suggesting that instruction in computer programming does not significantly enhance growth in logical thinking skills. However, this conclusion must be considered as tentative due to the small sample size and limited scope of the study. In addition, 10 weeks may be too short a time period to expect much growth in logical thinking skills. (Author/JN)
