本研究主要目的是探討不同摘略結果獲知對運動技能
學習效果的影響。以 134名女性國中學生為受試對象，利
用槌球進行實驗，分為兩個階段研究；第一階段將摘略長
度分為16（試做完16次後再給這16次的KR）、12、 8、 4
、 1等五組，目的是為尋求一個最佳的摘略長度；第二階
段以第一階段中最佳摘略長度為主，控制不同頻率的KR訊
息量（分為 100﹪、50﹪、25﹪等三組）。
經過實驗所得資料結果，以單因子變異數分析、杜凱
氏法事後比較進行統計分析。結果顯示，第一階段：分析
資料發現，絕對誤差(AE)立即給予KR組動作表現較其他組
別好，但彼此之間沒有顯著差異，在一天後的保留測驗上
以 4為摘略長度組有明顯的比其他（16、12、 8、 1）摘
略組別好。第二階段研究主要以 4摘略長度來探討其效果
，三種不同頻率KR組的立即動作表現沒有差異存在，在一
天後的保留測驗上， 100﹪頻率KR組有顯著的較佳表現，
但在四天後和一週後的保留測驗上，三組之間並沒有顯著
的不同。這發現指出在運動技能學習上摘略KR方式中KR出
現的頻率可能是其影響的因素之一。

This study was investigated in the effects of different
summary knowledge of results on motor skill acquisition.
One hundren and thirty-four female junior high school students
were served as subjects. Following assignment to groups,
subjects were tested on roque experiment. There were two
stage researches. Firstly , we examined on five summary
lengths of 16 (essentially KR after 16 trials), 12 , 8 , 4,
1 trials, searching for an optimal summary length. Secondly
, an optimal summary length was the praticing number
researched on the first stage , to control the different
frequency of KR ( 100﹪ , 50﹪ , 25﹪ ) on motor skill
acquisition .
One-way ANOVA, Tuckey's method were used to analyze the
data. The results showed that anyalysis of the absolute
error (AE) data for acquistion revealed all groups with
practice and the immediate KR group performed better than
all the summary groups which in turn did not show any
significant difference on the first stage. However the
results indicated that the 4-trial was better than for 16-,
12-, 8- or 1 trial summary length after 1-day retention test.
The second stage was an initial attempt to determine the
locus of the 4-trial summary legth effects. The immediate
performance data of three different frequency KR (100﹪,50﹪
,25﹪) did not show significant difference, but the 100﹪
frequency KR group data found performance to be the best
among on the 1-day retention test for all groups. The effect
of condition was significant, but the 4-day and 1-week
retntion tests were not. These findings suggest that the
frequency of KR presention may be one of the effective basis
on the summary KR effect on motor skill acquisition.
