物理学作为一门重要的自然基础科学,如今已是现代科学技术的中心学科之一。无论是工农业生产和国防现代化,还是信息技术与纳米技术等先进科学技术,都离不开物理学的基础理论知识。在整个物理教学过程中,初中物理教学是青少年进入物理知识宝库的入门和启蒙,是培养学生学习物理兴趣,具有初步观察事物、分析问题、解决问题能力的关键。因而在初中物理教学中激发学生对科学的兴趣,调动其学习积极性,对其今后的进一步深造打好基础有着重要作 As an important natural science, physics is now one of the central disciplines of modern science and technology. Both industrial and agricultural production and national defense modernization, or information technology and nano-technology and other advanced science and technology are inseparable from the basic theoretical knowledge of physics. In the whole process of physics teaching, junior high school physics teaching is the entry and enlightenment of adolescents entering into the treasure trove of physical knowledge. It is the key to cultivate students’ interest in learning physics, and has the ability of preliminary observation, analysis and problem solving. Therefore, in the junior high school physics teaching to stimulate students’ interest in science, to mobilize their enthusiasm for learning, to lay the foundation for further further study has important
