本研究主要目的在瞭解國小六年級學生實施理解式球類教學之成效。研究以排球及羽球爲教學項目，三十二位六年級國小學生及其體育教師爲研究參與者。蒐集資料的方法爲訪談、學習單及教師省思札記。教師安排每一個教學情境及步驟，協助學生學會運動規則及各項動作技能。本研究獲得的成效有第一、實施TGfU時應掌握之重要教學原則：適時修改規則與增加難度，以符合學生需求；調整器材，充實設備，以利活動之進行；適當地討論有助於學生釐清錯誤動作或概念；適時增加學生活動時間，滿足學生身體活動的需求；第二、在情意方面TGfU可促進學生團隊合作，激發學生自身責任感，並提高學生參與度。

The purpose of this study was to examine the results of Teaching Game for Understanding (TGfU) on a sixth grade class. Volleyball and badminton were the teaching items for this study. Participants were 32 sixth grade students and their physical education teachers. Data was collected by interviews, learning sheets and the reflective journals of the teachers. TGfU involves the teachers arranging every situation and step which then helps students learn the movements, rules, and skills necessary to participate in the activities. Two results from this research are discovered. First, important teaching principles that match with TGfU are as follows: The ability to timely modify rules and increase difficulty in order to conform to the need of students; support sufficient facilities and adjust equipment for the activities to properly proceed; encourage discussion that helps students understand wrong movements or conception, and increase the amount of time designed for the students to participate in the activities. Second, TGfU can encourage student teamwork, stimulate a sense of responsibility for the students, and increase the rate of student participation.
