近几年来,伴随着新课程改革,建构数学知识以数学操作为载体成了课堂的亮点。《义务教育数学课程标准(2011年版)》中也明确指出:教学中“做”比“知道”更重要,正如苏霍姆林斯基所说:“在手和脑之间有着千丝万缕的联系,这些联系起两方面的作用:手使脑得到发展,使它变成创造的、聪明的工具,变成思维的工具和镜子。”可见,动手操作是智力的起源、是思维的起点。
In recent years, along with the new curriculum reform, the construction of mathematical knowledge has become the highlight of the classroom with mathematical operation as a carrier. The Standard of Compulsory Education Curriculum Standard (2011 Edition) also clearly states that teaching “doing” is more important than “knowing” in teaching, as Sukhomlinski said: “Between the hands and the brain Are inextricably linked, these connections serve two purposes: the hand evolves the brain, turning it into a creative, clever tool, a means of thinking and a mirror. ”" Visually, hands-on manipulation is intellectual Origin, is the starting point of thinking.
