新的数学课程为每个学生都配有学具,但在实际教学中,很多教师因操作耗时、费力、低效等种种原因,常常省略学具操作环节,将这一过程用多媒体课件演示替代,致使学生的数学思维发展失去了一个行之有效的途径。心理学家皮亚杰认为:“思维是从动作开始的,切断了动作与思维之间的联系,思维就得不到发展。”因此,教师要帮助学生建立数感,就要为学生的动手操作提供更多的机会。下面就借助学具操作培养小学生数感的策略作一探讨。
The new mathematics curriculum is equipped with learning tools for each student, but in actual teaching, many teachers omit the learning process because of the time-consuming, labor-intensive and inefficient operation. This process is demonstrated in multimedia courseware Substitute, resulting in the development of students’ mathematical thinking has lost an effective way. Piaget, a psychologist, thinks: “Thinking starts from the action, cutting off the connection between action and thinking, and thinking can not develop.” Therefore, if teachers want to help students build a sense of number, The hands-on operation provides more opportunities. The following with the operation of learning tools to cultivate a sense of number of primary school students make a discussion.
