建构主义认为学习是一种建构,学习过程应该是个体将知识建构到自己的认知结构中的过程。而《课程标准》指出:“有效的数学学习活动不能单纯地依靠模仿和记忆,动手操作、自主探索和合作交流是学生学习数学的重要方式。”因此,教师要重视学生的实践操作,让其在动手中获得充分的感知,并能激发学习兴趣、发展思维、主动地将知识建构到自己的认知结构当中。在传统的教师讲授占主导的教学模式下,加强学生有效动手操作是小学数学教学方法改革的发展趋势。
Constructivism holds that learning is a kind of construction, and that the learning process should be an individual’s process of building knowledge into its own cognitive structure. The “curriculum standard” states: “Effective mathematics learning activities can not rely solely on imitation and memory, hands-on operation, independent exploration and cooperation and exchange are important ways for students to learn mathematics.” Therefore, teachers should pay attention to students’ practical operation, Let them get full awareness in their hands, and can stimulate interest in learning, development of thinking, take the initiative to build knowledge into their own cognitive structure. Under the teaching mode dominated by the traditional teachers, strengthening the students’ effective hands-on operation is the trend of the reform in the teaching methods of primary mathematics.
