新课程标准强调师生交往,建构互动的教学关系,这是一种新型的数学教学关系,也是一种新的数学文化。在积极的、和谐的学习氛围中,老师引导学生主动地从事观察、实验、猜想、验证与交流等数学活动,并与学生平等地交往互动,共同参与知识的形成过程和发展过程,互教互学,共同发展,共同进步,师生之间形成一个“数学学习共同体”。 The new curriculum standard emphasizes the interaction between teachers and students and constructs interactive teaching relationship. This is a new type of mathematics teaching relationship and also a new mathematical culture. In a positive and harmonious atmosphere of learning, the teacher guides students to take the initiative to engage in mathematical activities such as observation, experiment, conjecture, verification and exchange, and exchanges and exchanges with students on an equal footing, taking part in the process of forming and developing knowledge, Learn, develop together, make progress together, form a “community of mathematical learning” between teachers and students.
