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.
