《人民教育》1962年第8期发表的《中学物理教学中的理論和实际的关系》一文,內容生动具体,在物理教学怎样联系实际方面,对我們有不少启发。但文中會提到,路灯的綫路是串联的(見第23頁左栏第24行),我认为还值得研究。实际上,路灯也是并联的,不过是用了总开关,不像照明电灯那样,一个电灯一个开关,說“路灯則是串联”,是不符
The article People’s Education, No. 8, 1962, entitled “The Relationship between Theory and Practice in Middle School Physics Teaching”, is vivid and specific. It gives us a lot of inspiration on how physical teaching can relate to reality. However, it will be mentioned in the text that the street lights are connected in series (see line 24 in the left column on page 23), which I think is worth studying. In fact, the lights are also in parallel, but with the master switch, unlike the lighting of a lamp, a light switch, saying “street lights are in series,” is inconsistent
