在进行初中物理第二册,第五章《能源的开发和利用》一节的教学时,我认为配合教学内容,一方面应使学生结合所学的知识,联系实际,培养动手能力。另一方面,结合当今世界面临着能源紧张问题,对中学生进行能源教育是十分必要的。基于这两点,课后我组织学生研制直接利用太阳能的简易设备——吸热式集热箱。效果令人满意。
In the teaching of Junior High School Physics Book 2 and Chapter 5 “Development and Utilization of Energy”, I believe that in conjunction with the teaching content, students should combine the knowledge they have learned with the actual situation and cultivate practical skills. On the other hand, with the energy shortage in the world today, it is necessary to educate middle school students on energy. Based on these two points, after the class, I organized students to develop a simple heat-absorbing heat-collection box that is a simple device that directly uses solar energy. The effect is satisfactory.
