在高二的物理教学中,振動与波这一章是教師和学生都很感到吃力的。因此我創造了一些教具,把一些靜止的示意圖變成可以連續活动的模型,解決了教學上的一些困難。現將这些教具的製法和使用介紹於後。一、示波器在講横波時沒有儀器学生還可以理解,在讲縱波時,若无示波器学生就很难理解。现在市面上出售的有馬哈示波器,但是这種儀器價格較高,使用時还有一些缺點(後面將加敍述)。因此我在1952年根據馬哈示波器加以改裝,做成圖1所示的形式。這一示波器,曾在南京市的自製教具展覽會上展出,並在1953年度的江蘇省中等學校教師進修班上演示過,南京和徐州也有學校倣製了。
In the physical education of sophomore year, the vibration and the wave of this chapter is very hard for teachers and students. So I created some teaching aids, turned some of the static diagrams into models that could be continuously active, and solved some teaching difficulties. The teaching methods and use of these teaching aids are introduced below. First, the oscilloscope is not talking about the instrument in the transverse wave Students can also understand, when talking about longitudinal waves, without oscilloscope students it is difficult to understand. There are Maha oscilloscopes available on the market today, but the high cost of such instruments still has some disadvantages when used (as described later). So I converted it in 1952 on the basis of the Maha oscilloscope, in the form shown in Figure 1. This oscilloscope was exhibited at the home-made teaching aids exhibition in Nanjing and was demonstrated at the 1953 Jiangsu Secondary School Teacher Training Class. Schools in Nanjing and Xuzhou also replicated.
