操作能力是由一系列的外部动作构成的,是通过练习形成和巩固起来的一种含理化的随意行动方式。修订后的小学数学教学大纲,突出了“动手操作”在教学活动中的地位和作用,强调要根据学生的年龄特征和认识规律,注意通过实际操作,使学生更好地掌握所学内容。盛大启、陈春圣、徐国梁、等同志的文章对数学中的动手操作问题进行了多侧面的“扫描”,能给我们以新的思考。 Operational ability is composed of a series of external actions, formed by the practice and consolidation of a physical and chemical arbitrary action. The revised primary school mathematics syllabus highlights the status and role of “hands-on operation” in teaching activities. It emphasizes that according to the students' age characteristics and cognition rules, attention should be paid to making students better master what they have learned through practical operation. Shengdaqi, Chen Chunsheng, Xu Guoliang and other comrades conducted a multifaceted “scanning” of the hands-on problems in mathematics, giving us new thinking.
