The Effect of Bounce Ball Drills on Underhand Volleyball Passing Skills Among Female Students in Extracurricular Activities at Seluma State High School No. 8

Abstract

This study aims to determine the effect of bounce ball training on underhand volleyball passing skills among female students participating in extracurricular activities at Seluma State High School No. 8. The study employed an experimental approach using a one-group pretest-posttest design. The population and sample consisted of 15 female students, selected using total sampling. Underhand passing skills were measured through a one-minute wall-passing test, while the data were analyzed using descriptive statistics, the Lilliefors normality test, the homogeneity test, and the paired t-test. Based on the individual research data, the average score increased from 15.53 on the pretest to 23.67 on the posttest, representing an increase of 8.13 points (approximately 52.36%). The results of the normality test showed that the pretest Lo value of 0.187 and the posttest Lo value of 0.156 were smaller than the table value of 0.220, while the homogeneity test yielded a calculated F value of 0.55, which was smaller than the table value of 4.67. The hypothesis test yielded a t-calculated value of 13.20, which is greater than the t-table value of 2.160 at a significance level of 0.05 with 14 degrees of freedom. Thus, the bounce ball drill has a significant effect on improving underhand passing skills in volleyball. This method can be used as a more varied alternative drill in teaching basic volleyball techniques during school extracurricular activities.
