• 中文摘要： 本文以合作行動研究法，結合二位作者及一位研究教師，進入一個五年級班級，探討數學討論的實際運作，研究過程經歷一個學期四個教學方案的演變，也評估各個方案的成效與缺失，然後又從佈題、引導策略、與教師角色方面加以討論。最後，作者又結論出可行的方案，並提供省思與啟示。
• 英文摘要： The purpose of this article was to explore discussion in the math classroom and to find available ways to carry out math discussion. The participants were the two authors of this article; a research teacher and a fifth grade teacher. This cooperative action research study was conducted to view a discussion in a fifth grade mathematics class. During a semester, four teaching strategies evolved, one from each another. The benefits and weaknesses of each have been discussed. The discussion approach is also discussed from the perspectives of problem posing, guiding strategies, and the teacher's role. In addition, the authors' reflections and the implications of using a discussion approach are offered.
