4.全電路的歐姆定律在進而分析電流定律的教學問題中,我們將只較詳細地分析一下全電路的歐姆定律,因為這一部分的教學困難最大。如果有人問:‘全電路的歐姆定律的教學的困難到底是什麽呢?’我們的回答是:這個定律的教學的全部困難在於缺乏足够直觀的實驗基礎。關於這個問題,所有在實際中最廣泛應用的教學方式,包括克拉屋克里斯在1950年第五期‘物理教學’雜誌上發表的論文‘中學的歐姆定律的教學’中所指出的教學方式,也包括沙哈諾夫在1951年第三期‘物理教學’雜誌上發表的論文‘再論中學裏歐姆定律的教學’中所指出的教學方式,都建基於用間接的方法來證明這個定律,這對學生是很困難的並且不能使
4. Ohm’s Law of Full Circuits In the teaching of analyzing the law of current, we will only analyze the Ohm’s law of the full circuit in more detail because of the most difficult teaching in this part. If one asks, ’What is the difficulty of teaching Ohm’s law for full circuits?’ Our answer is that the whole difficulty with teaching this law lies in the lack of an intuitive enough experimental basis. On this subject, all the most widely practiced teaching methods in practice, including those taught by Clauch Christi in the essay “The Teaching of Ohm’s Law in High School” in the Fifth Physics Bulletin, 1950, Also included is Shahwanov’s teaching of the essay “Revisiting the Teaching of Middle Ohm’s Law in High School” in the third issue of Physics Teaching, 1951, based on the indirect method of proving this law, which It is very difficult for students and can not make it
