数学交流是学生数学思维活动的延续,是思维活动社会化的重要环节。通过交谈、讲述、倾听、阅读,能让观点得到论证,发现得以共享,猜测得到肯定,零乱的知识得到组织,模糊的认识得以澄清,交流对于学生学习和掌握数学是必不可少的。就课堂教学中的数学交流而言,主要包括三个方面:一是数学知识的交流;二是数学体验的交流;三是解决问题心得的交流。作者在教学中针对数学交流的有效性进行了大量的实践研究,提出了有效数学交流的策略,旨在培养学生数学交流能力,提高课堂教学效率。
Mathematical communication is a continuation of students’ mathematics thinking activities and an important part of the socialization of thinking activities. Through conversation, speaking, listening, and reading, the viewpoints can be demonstrated, the findings can be shared, and the guesses can be affirmed. The scattered knowledge can be organized and the fuzzy understanding can be clarified. Communication is essential for students to learn and master mathematics. As far as mathematics communication in classroom teaching is concerned, it mainly includes three aspects: one is the exchange of mathematical knowledge; the other is the exchange of mathematical experience; and the third is the exchange of ideas for solving problems. The author conducts a large number of practical studies on the effectiveness of mathematical communication in teaching, and puts forward strategies for effective mathematical communication, aiming at cultivating students’ mathematical communication skills and improving classroom teaching efficiency.
