学具,顾名思义就是教师教学、学生学习的工具。我们常说:“我听见了,但可能忘记;我看见了,就可能记住;我做过了,便真正理解了。”《数学课程标准》也指出:“有效的数学学习活动不能单纯地依赖模仿与记忆,动手实践、自主探索与合作交流是学生学习数学的重要方式。”“纸上得来终觉浅,绝知此事要躬行。”儿童的智慧就在他们的指尖上,让学生通过各种操作活动,经过分析和思考,形成准确的表象,在实践中体验数学、探究规律。笔者结合自己多年的教学实践,对优化学具操作指导,提高课堂教学效率谈一 School tools, as the name suggests is the teacher teaching, student learning tools. We often say: “I heard, but may forget; I saw it, it is possible to remember; I have done, they really understand. ” “Mathematics Curriculum Standards also pointed out: ” effective mathematics learning activities Can not simply rely on imitation and memory, hands-on practice, independent exploration and cooperation and exchange is an important way for students to learn mathematics. “” On their fingertips, students are allowed to analyze and think through various operational activities to form an accurate representation of the mathematical experience in practice. The author combined his years of teaching practice, optimize the operation guidance with learning tools to improve the efficiency of classroom teaching talk about a
