Abstract
本研究的主要目的是探討六週分段式教學法與全部式教學法對國中男生在跳遠運動學習之影響。本研究係以研究者任課之四個班級,每個班級8位男學生為受試對象,並以隨機分配的方式,將受試者分配至實驗組兩個班與控制組兩個班。最後共有32 位學生完成本次實驗,每組各16位。以CASIO FH100 型高速攝影機進行拍攝,高速攝影機採樣頻率為120fps。每位受試者實施急行跳遠測驗三次,以最佳一次成績進行資料處理,並取得跳遠起跳運動學相關參數進行分析。所得資料以相依樣本t考驗(α=.05)考驗各組教學法前後測成績與運動學參數是否有顯著差異情形。 一、 控制組在經過六週全部式訓練後,全部式教學法在跳遠測驗成績前、後測比較中達顯著差異(p<.05),運動學相關參數經訓練後則未有顯著差異情形。 二、 實驗組在經過訓練後,分段式教學法在前後測驗成績、助跑末速度、踩板時間與重心騰起角度方面有顯著差異情形(p<.05):包括助跑末速度平均增加0.62m/s、平均起跳重心變化量增加1.97cm、踩板時間平均減少0.013s、重心騰起角度平均增加3.3度,跳遠成績平均增加達49公分。 三、 本研究結果顯示,在經過六週分段式教學法訓練後,對於國中男學生的跳遠能力有明顯的幫助,不論是在助跑末速度、踩板時間等參數方面,跳遠成績亦能有效提升。且藉由漸進和安全的訓練模式,在六週內便可以達到明顯的效果,又可以避免選手的傷害,是一種安全而又有效率的訓練方式。
The purpose of the present study is to investigate the influence between six-week divided teaching method and whole teaching method for junior high school male students’ learning of long jump. The subjects of the study are the experimenter’s students ( total: 40 ), who were chosen randomly from four different classes. The subjects were evenly divided into two groups: the experimental and the control groups. Each subject was asked to jumped three times and his/her best grade was adopted in the jump test which was recorded in 120fps by a digital high-speed video camera (CASIO FH100). The jump distance of these subjects was analyzed into some relative kinematic parameters and examined in correlated-samples T-tests to investigate whether the two groups performed significantly between their pretest and posttest. 1. The subjects of the control group reach significant difference in their jump distance and after-approaching speed in the posttest in the whole teaching method (p<.05). 2. After six-week training, the experimental group have significant improvement in their jump distance, the distance between the centers of gravity of their takeoffs, the velocity when jumpers step on the takeoff board and the elation angle of the center of the gravity. The significance includes the velocity when jumpers step on the takeoff board increases 0.62m/s (mean), the elation angle of the center of the gravity raises 3°( mean) and the jump distance increases 49cm (mean). 3. The present study shows that the subjects have significant improvement in variables such as the velocity when jumpers step on the takeoff board and the jump distance after six-week divided training program. Furthermore, subjects have significant improvement by this gradual and safe training mode during the six weeks. In addition, the six-week divided training method, which can prevent athletes from getting hurt, is a safe and effective training.
