本研究目的在探討44mm桌球運用於大學體育課上，對於學生桌球反手推擋學習表現的影響。方法：本研究為準實驗研究，採不等組前後測設計，針對二班大學二至四年級選修初級桌球課程學生，並隨機分派為一班為實驗組與一班控制組，實驗結束後獲得實驗組24組、控制組21組有效樣本，共45組90名學生。教學實驗過程中，實驗組實施44mm桌球教學，控制組則實施傳統式40mm桌球教學，且兩組學生皆接受前測、實驗處理、後測等實驗程序，並以成對樣本t檢定、單因子共變數分析等統計方法進行考驗。結果：1、經44mm與40mm球體的教學後，其桌球反手推擋學習表現上均有顯著的進步；2、使用44mm球體教學的學習表現比40mm球體教學有顯著的進步。結論：根據本研究的結果建議從事桌球教學的教師與專業人員可以使用44mm球體做為桌球反手推擋的輔助教學工具。

This paper considers the effect of 44mm table tennis ball using in the university table tennis classes for students to acquire the skill of backhand push. In this study, the pre-test and post-test groups are designed to be unequal. 2 elementary table tennis classes (within140 students) are chosen to participate in the experiment. Candidates were separated into 70 groups (2 students into one group), then randomly assigned one class to the experimental group and the other to the control group. After the experimentation, 45 effective samples are obtained, including 24 experimental and 21 control groups. In the process, the experimental group adopted the teaching method of 44mm ball, while the control group adopted the traditional teaching method of 40mm ball. However, both of them followed the same procedures of pre-test, experiment, and post-test. The data were examined by the paired samples t-test, and one-way ANOVA. The results indicated that: Students in the 44mm group could gain skill of backhand push more effectively than those in the traditional 40mm ones. The results of this study suggested the method of teaching table tennis through 44mm ball, and a direction for future work in this area, which could be applied for further research.
