Development of dexterity of 13-14-year-old students during volleyball lessons

The purpose of the article: to determine the specifics of the development of general and special dexterity of students aged 13-14 years in the process of extracurricular volleyball lessons. The methodology of the process of developing the dexterity of middle school students during volleyball lessons is based on the methodological features of the implementation of the complexity and variety of tools, the gradual increase in the complexity and variability of the conditions for performing exercises, the individualization of the educational and training process, the use of game methods, and pedagogical control over the level of performance of indicators. The scientific novelty consists in the determination of data on the dynamics of the development of general and special dexterity of students aged 13-14 years based on the results of staged pedagogical control, the results of which allow determining the effectiveness of the implemented means, percentage increases, reliability of motor tests, their ranks in the general correlation variance and predicted parameters of changes. Conclusion. The results of the pedagogical experiment indicate that the average percentage increase in dexterity indicators according to the results of the pedagogical experiment is 28,17%, the reliability of most tests was within r=0,865-0,964.
