THE EFFECT OF DIRECTED INVENTION METHOD STUDIES ON BASIC SKILLS AND REACTION TIME IN VOLLEYBALL

Aim: The aim of this study was to examine the effects of the directed invention method on basic volleyball skills and reaction time. Materials and Methods: A total of 40 university students with no previous volleyball training experience, enrolled at Bayburt University during the fall semester of the 2024-2025 academic year, participated in the study. Participants were divided into an experimental group (n = 20), which received the directed invention method combined with traditional volleyball training, and a control group (n = 20), which received traditional volleyball training alone. Each group consisted of 10 male and 10 female students. Both groups participated in an 8-week training program. A quasi-experimental pretest-posttest control-group design was used. Basic volleyball skills were assessed using a rating scale and direct observation, while reaction time was measured using the BlazePod system and wireless light disks. Descriptive statistics and normality tests were performed. The Mann-Whitney U test was used for between-group comparisons, and the Wilcoxon signed-rank test was used for within-group comparisons of non-normally distributed data. Statistical analyses were performed using SPSS version 26.0.
