| 摘要: | 數學溝通能力的培養有助於學生反思和釐清數學概念，能夠提升學習者對於數學概念的理解和表達能力，增進數學的學習表現和解決問題之能力。教育部亦將「數學溝通能力」納入九年一貫課程綱要中，成為學生培養數學能力重要指標之一。然而台灣的教育仍是以升學與成就為取向，忽略了學生在學習過程中的表現，缺少對於學生數學溝通能力的培養，在傳統大班教學環境中，每位學生不見得都有機會能夠表達自己的學習想法，甚至是容易被忽略，因此有研究提出同儕互教能以相近的認知想法以及語言進行教與學的過程，促進學習者間的溝通有助於知識的吸收和理解。因此，本研究以同儕互教為基礎發展培養國小學童數學解題溝通能力活動，讓學生輪流扮演教學者與被教者，透過電腦系統支援學生彼此相互解釋自己的數學解題想法，促進學生學習表達自我和理解他人之數學想法，並利用數學解題溝通能力測驗卷、問卷、實驗活動及訪談法進行資料收集與結果探討。研究發現同儕互教有助於增進學童之數學解題溝通能力，不同數學解題溝通能力成就之學生隨著同儕互教活動的進行，其能力表現皆不斷的提升且逐漸接近，而學生對於同儕互教亦持有正向的態度，認為同儕互教能夠幫助他們培養以及提升數學解題溝通能力。Mathematical communication ability help students to reflect and clarify mathematical concepts can enhance learners’ mathematical understanding and expression, to promote mathematical learning performance and problem solving skills. Mathematical communication ability has become one of the important indicators to evaluate students’ mathematical ability. However, most of the math courses in elementary school rarely focus on culturing students’ mathematical communication ability, still learning based on an achievement-oriented way. In addition, each student may not have the opportunity to express their own ideas in the traditional teaching environment, even easy to be ignored. Previous researches have showed that peer tutoring could promote communication between learners contribute to the knowledge understanding, also enhance the learning performances.Therefore, in this study, peer tutoring used as the main axis of research activities design, and also develop a system to support peer tutoring for enhancing mathematical communication ability of elementary students. Students prepare their own teaching materials and teach each other through the system, explaining their mathematical problem-solving ideas by using graphics, mathematical formula, literal interpretation, and oral, also use mathematical communication skill test, questionnaires, experiments, and interviews as the data collected. The research result has showed that peer tutoring could enhance students’ mathematical communication ability, and also students with different mathematical communication ability its performance are constantly ascend and gradually close. Besides, students holds a positive attitude towards peer tutoring, believe that peer tutoring can help them to enhance mathematical communication ability. |
