A Study on the Teaching Effectiveness of Computer Simulation Technology in Assisting Volleyball Tactical Training and the Improvement of Athletes' Cognitive Abilities

 This paper applies computer-assisted technology to the field of volleyball instruction, designing a CAI system for volleyball tactical training. Relevant experiments were then designed to evaluate the teaching effectiveness of the CAI-based volleyball tactical training method and its impact on athletes' cognitive abilities. There were no significant differences in basic technical skills and tactical combinations between the experimental group and the control group in the pre-test. After the experiment, significant differences emerged between the two groups in basic technical skills and tactical combinations (P < 0.05). The experimental group scored higher than the control group by 4.01, 2.60, 3.30, 3.60, 3.22, 3.82, 4.42, 3.76, and 4.08 points across nine sub-dimensions. The cognitive abilities of athletes in both the experimental and control groups remained at similar levels in the pre-test. After the experiment, the experimental group outperformed the control group by 6.68, 7.58, 9.76, and 9.20 points in four sub-dimensions of cognitive ability, with a significance level of less than 0.05. This indicates that the CAI-based volleyball tactical training method used in this study has good teaching effects and can significantly improve athletes' cognitive abilities.
