摘要
本文择要叙述直流电路定律和干涉衍射这两个问题的教法。对第一个问题主要突出教学中如何删繁就简,明快清晰,提出以统一的法则贯穿直流电路诸定律,使学生学得活,记得牢;对第二个问题,则力求澄清学生对干涉和衍射这两个物理概念的一些模糊认识,使学生明白干涉和衍射并不能截然划分。
This paper described the author's teaching experience in the law of the directlurrent route and the question of interference and diffraction. For the first question, he dwells on the united rule governing each law of direct current route to make students study easy. For the second question, he makes mudelling concept clear for students in understanding interference and diffraction, and the retalionship between interference and diffraction.
