Although research has investigated study skills, self-concept, and academic achievement in college populations, no study has focused on these variables with high school students. To investigate changes in study skills, and the relationships among study skills, self-concept, and academic achievement for high school students, 54 students (28 males, 26 females) participated in a computer-assisted (CAI) study skills module. Students also completed pre- and post-tests on study skills and self-concept (Tennessee Self Concept Scale). An analysis of the results showed that students gained significantly from the study skills program and reported greater self-satisfaction after completing the program. Greater significant gains were reported for the experimental group when compared to the control group, and for seniors and high achievers, when post-test scores were compared with their pre-test scores. Grade point averages correlated significantly with study skills and with one self-concept scale, moral-ethical. These findings suggest that effective study skills lead to academic success and academic success leads to greater self-satisfaction. (Author/BL)
