《数学新课标》指出:有效的数学活动不能依赖模仿与记忆,动手实践、自主与合作交流是学生学习数学的重要活动。教学中以学生为主体,要让学生在原有的知识和经验的基础上,在主动参与中,通过操作和实践来完成新知识的获取,“知识来源于动作”讲的就是这个道理。教师只有在教学过程中巧妙地引导学生动手、动脑、动情地实践,学生的发展才能真正落实。动手操作益处多,对于小学数学教学,动手操作有着非常重要的作用。
The New Curriculum Standard of Mathematics states that effective mathematics activities can not rely on imitation and memory, practice, and autonomy and cooperation and exchange are important activities in which students learn mathematics. Teaching students as the main body, let the students based on the original knowledge and experience, in the active participation, through the operation and practice to complete the acquisition of new knowledge, “knowledge comes from action ” is the truth. Teachers only skillfully guide students in the teaching process, brains, emotional practice, the development of students can really implement. Hands-on benefits and more, for primary school mathematics teaching, hands-on operation has a very important role.
