笔者教学实践证明,动手操作能力的培养,是提高课堂教学效率的一项有效措施,解决数学知识抽象性与小学生思维形象性之问矛盾的一种有效手段。动手操作可以把数学中的一些抽象问题生活化,学生学习时就能轻而易举地理解。可以说,有效的操作活动也是是培养学生创新精神的源泉。 The author’s teaching practice has proved that the ability of hands-on training is an effective measure to improve the efficiency of classroom teaching and solve the contradiction between the abstract knowledge of mathematical knowledge and the thinking of pupils. Hands-on exercises can bring to life some abstract issues in mathematics that students can easily understand when studying. It can be said that effective operational activities are also the source of cultivating students’ innovative spirit.
