演示实验是物理课堂教学中极其重要的组成部分。要揭示物体运动规律,引入新的物理量,描述各物理量之间内在联系,验证物理定律,巩固已学到的物理知识,用演示实验加以辅助配合,不仅能激发学生学习物理的好奇心和求知欲望,而且也能进一步培养学生学习物理的思维能力和科学研究方法。演示实验在物理课堂教学中能发挥其形象、真实、吻合学生认知规律、培养学生观察、思维、分析等能力的独有功能.要提高物理课的效率,必须精心设计演示实验。
Demonstration experiment is an extremely important part of physics classroom teaching. To reveal the laws of motion of objects, introduce new physical quantities, describe the intrinsic connections among physical quantities, verify physical laws, consolidate learned physical knowledge, and assist them with demonstration experiments, not only inspire students to learn physical curiosity and desire for knowledge , but also can further develop students’ ability to learn physics and scientific research methods. Demonstration experiment can play its unique function of image, reality, conforming to students’ cognitive rules, and cultivating students’ ability of observation, thinking, analysis, etc. in physical classroom teaching. To improve the efficiency of physics lessons, demonstration experiments must be carefully designed.
