Methodic of pedagogic control of 16-17 years’ age girls’ motor fitness

Решение проблемы повышения уровня двигательной подготовленности школьников связывается с организацией педагогического контроля на уроках физической культуры. Предполагалось, что основой для педагогического контроля уровня двигательной подготовленности девушек 16-17 лет является дискриминантная модель. Цель : определить методологические подходы к педагогическому контролю уровня двигательной подготовленности девушек 16-17 лет. Материал: В исследовании принимали участие 28 девушек старших классов (14 девушек 16 лет и 14 девушек 17 лет). Материалы исследования обработаны в программе статистического анализа - IBM SPSS 20. Результаты: В процессе дискриминантного анализа была создана прогностическая модель для определения принадлежности к группе. Данная модель строит дискриминантную функцию в виде линейной комбинации предикторних переменных. Она обеспечивает лучшее разделение групп. Коэффициент корреляции между расчетными значениями дискриминантной функции и показателями принадлежности к группе равен r = 0,843. Это свидетельствует о высокой прогностичности первой канонической функции. Выводы: Девушки 16 лет имеют лучшую скоростно-силовую подготовленность, чем девушки 17 лет. Это указывает на то, что в 17 летнем возрасте причиной отставания от 16 летних девушек является их недостаточная двигательная активность. На основе канонических коэффициентов дискриминантной функции возможна классификация девушек 16 и 17 лет по уровню двигательной подготовленности в соответствии с их возрастом. Это имеет практическое значение для разработки эффективных программ физической подготовки девушек старших классов. Дискриминантная модель может быть использована для педагогического контроля уровня подготовленности девушек 16 и 17 лет.

Informative pedagogic control indicators of 14-15 years age girls’ motor fitness

Purpose: to determine informative indicators for in-group and intra-group control of 14-15 years age girls’ motor fitness. Material: in the research 99 girls participted: 14 years old (n=38), 15 years old (n=61). Results: for control of 15 years age girls’ motor fitness the most informative are indicators of speed power, dynamic power endurance and physical condition. It was found that 14 years age girls have better power fitness than 15 years girls. It points at the fact that in 15 years’ age the reasons of lagging behind 14 years girls are increase of body mass and reduction of motor activity. Conclusions: the received data show that factorial analysis as well as discriminant one is methodological base for determination of tests’ in-group and intra-group informational potential. The most informative tests for determination of age dynamic are static and dynamic power endurance of abdomen muscles and connected with them result of long jumps from the spot.
