《义务教育数学课程标准》指出:学生学习应当是一个生动活泼的、主动的和富有个性的过程,除接受学习外,动手实践、自主探索与合作交流也是数学学习的重要方式。所以,在新课程背景下,教师要更新观念,从学生的角度出发,采用多样化的教学模式,以促使学生在获得基本的数学知识的同时,也感受到数学的价值。 The Standard of Compulsory Education Mathematics Curriculum states that student learning should be a lively, active and individualized process. Apart from accepting learning, hands-on practice, independent exploration and cooperation and exchange are also important ways for learning mathematics. Therefore, in the context of the new curriculum, teachers should update their concepts and adopt a diversified teaching model from the perspective of students so as to encourage students to acquire the value of mathematics while acquiring basic mathematical knowledge.
