过去在讲高三“电磁振荡和电磁波”的一章中,往往感到教材和实践的配合较少,一般学生在学习了基础理论知识以后,对装接一、二管接收机还是比较陌生;相反的,有的学生对装接技术方面虽有一些经验,但对理论知识却理解的不够,难以和实践配合.但是无线电技术是青少年喜爱的活动之一,那么我们应该如何引导学生对这一门科学通过讲授“电磁振荡和电磁波”使理论和实践相结合呢?为了贯彻党的教育方针,教育必须更好的为无产阶级政治服务,和劳动生产紧密的相结合,最近我们把教材内容和教法方面作了初步打算,但很不成熟,尚希有经验的同志,多予指教. In the past, the third chapter “electromagnetic oscillations and electromagnetic waves” in the chapter, often feel that there is less cooperation between teaching materials and practice, the average student after learning the basic theoretical knowledge, the receiver is still relatively unfamiliar with the first and second receiver; On the contrary, some students have some experience in the connection technology, but they do not understand theoretical knowledge enough, and it is difficult to cooperate with practice. However, radio technology is one of the activities that teenagers love, so how should we guide students to this? The door science combines theory and practice by teaching “electromagnetic oscillations and electromagnetic waves”. In order to implement the party’s education policy, education must better serve proletarian politics and integrate closely with labor production. Recently, we have adopted teaching materials. The contents and teachings were initially planned, but they were immature and experienced comrades gave advice.
