چکیده
هدف پژوهش حاضر، بررسی تأثیر اطلاعات افزودة ویدئویی انتخابی و اجباری بر یادگیری حرکتی شوت جفت بسکتبال با تأکید بر نظریة نقطة چالشبود. تعداد 80دانشجوی پسر (۱۸تا 22سال) به‌صورت داوطلبانه انتخاب شدند و بعد از همگن‌سازی براساس نمرات پیش‌آزمون اول (بلوک پنج‌کوششی)، به‌صورت تصادفی در چهار گروه 20 نفری خود-کنترل، جفت‌شده، آزمونگر- کنترل و کنترل قرار گرفتند. ویدئوی آموزشی از مدل ماهر که اجزای بیومکانیکی حرکت را نمایش می‌دهد، به‌مدت شش دقیقه ارائه شد. سپس، پیش‌آزمون دوم (بلوک پنج‌کوششی)انجام شد. مرحلة اکتساب شامل 10 بلوک پنج‌کوششی بود. آزمون یادداری 24 ساعت بعد، طی دو بلوک 10 کوششی انجام شد. برای مقایسة تفاوت نمرات دقت و تکنیک در مرحلة اکتساب، از تحلیل واریانس مرکب با اندازه‌گیری تکراری (بلوک) 10 × (گروه) 4 و در مرحلة یادداری، از تحلیل واریانس یک‌راهه استفاده شد (0.05≥ P). در مرحلة اکتساب، نتایج دقت پرتاب نشان داد که اثر اصلی بلوک معنادار است؛ اما اثر اصلی گروه و تعامل بلوک و گروه معنادار نیست. در مرحلة یادداری، امتیازات دقت پرتاب آزمودنی‌ها در شرایط آزمایشی به‌طور معناداری بیشتر از شرایط کنترلاست. طی دورة اکتساب، نتایج فرم اجرای مهارت نشان داد که اثر اصلی بلوک، گروه و تعامل بلوک و گروه معنادار است. فرم اجرای مهارت آزمودنی‌ها در شرایط مشاهدة خود-کنترل به‌طور معناداری بهتر از شرایط جفت‌شده و کنترلاست. همچنین، در مرحلة یادداری، فرم اجرای مهارت در شرایط مشاهدة خود-کنترل به‌طور معناداری بهتر از دیگر شرایط آزمایشیاست. علاوه‌براین، نتایج نشان داد که طی دورة اکتساب و یادداری، فرم اجرای مهارت آزمودنی‌ها در شرایط مشاهدة آزمونگر-کنترل به‌طور معناداری بهتر از شرایط کنترلاست.

چکیده [English]
The aim of this paper is to investigate the effect of selective and compulsive video augmented information on motor learning of Basketball Jump Shot emphasizing on the Challenge Point theory. 80 male students (18to22 years old) were voluntary selected. After homogenization based on the first pre-test scores (block5of trial) they were randomly assigned into four groups (20subjects) of self-control, yoked, examiner-control, and control. Instructional video of the expert model demonstrating specific biomechanical component was provided for 6 minutes. And then a second Pre-test (block5of trial) was done. The acquisition phase included 10 blocks of 5 trails and the retention test was performed in 2 blocks of 10 trails after 24 hours. The acquisition accuracy and technique scores differences were analyzed using a repeated measures analysis of variance (RM-ANOVA) in 4(groups) x 10(Block). The retention accuracy and technique score differences were analyzed using the analysis of variance (ANOVA). The results of accuracy in the acquisition phase showed that the main effect of the block is significant. In the retention phase, the accuracy scores in the experimental conditions were significantly higher than the control group. The results of accuracy in the acquisition phase demonstrated that the main effect of the block, group, and interaction of the block and the group is significant, and the skill performance of self-control group was significantly better than the yoked and control groups. In the retention phase, the self-control group technique of skill performance was better than other experimental conditions, and examiner-control group was significantly better than the control conditions during the acquisition and retention phases.
