初中物理共有二十五个“小实验”(包括一个“小制作”),这些实验虽小,但它们的作用并不小。只要我们正确引导,将对学生产生多方面的积极影响。首先,“小实验”都有一定的趣味性,能激发学习兴趣。“小实验”不花钱、在身边,一般采用日常用品,多与学生的生活有关,富于生活气息,使学生倍感亲切。可在家里做,能“学玩结合”,即“在学中玩,在玩中学”。他们可以尽情地摆弄,反复地改动,能达到动手动脑的目的,使初中生好奇好动的特点得以充分发挥,可以趣激学。初中物理教学,在某种意义上讲,叫做培养兴趣、训练习惯的教学。尽管物理学本身丰富多彩,引人入胜,但是,对于刚刚接触物理的十三、四岁的少年而言,物理知识 There are twenty-five “small experiments” (including a “small production”) for junior high school physics. Although these experiments are small, their role is not small. As long as we guide it correctly, it will have many positive effects on students. First of all, “small experiments” have a certain degree of interest and can stimulate learning interest. The “small experiment” does not cost money and is used by people. It generally uses daily necessities, is related to students’ lives, and is full of life atmosphere, making students feel at home. Can be done at home, can “learn to play with”, that is “playing in school, playing in middle school.” They can play with each other, change it repeatedly, and achieve the purpose of moving hands and brains so that the curiosity of the junior high school students can be fully utilized. Junior high school physics teaching, in a sense, is called the training of interest, training habits. Although physics itself is rich and colorful and fascinating, physical knowledge is available to 13 or 4 year olds who have just met physics.
