长期的教学经验让我觉得,同学们学习此内容的困难所在,就是学生接触实际电路较少,遇到短路的情况则更少,因此学生在学习“短路”时感到抽象,难以理解,而短路的判断,短路造成的电路结构的变化等问题的试题有一定的灵活性和难度,使有关“短路”的习题是学生在学习中的难点,因此,对“短路”方面的习题训练应值得重视,加以突 Long-term teaching experience makes me feel that the difficulty of students in learning this content is that students have less actual circuit and fewer short-circuits, so students feel abstracted and difficult to understand when they learn short-circuit, Short circuit judgment, short circuit caused by changes in the circuit structure and other issues of the test questions have some flexibility and difficulty, so that the “short circuit ” exercises are difficult for students in learning, therefore, Exercise training should be worth attention, to be sudden
