农村中学办学条件相对较薄弱,如果师生能充分运用好生动、形象、直观而又易取易制的教具、学具投入教学则能收到与实验室同样效果。这里向大家推荐一件随手可得、不需成本的物理教(学)具,它就是圆柱形可乐瓶。教师可让每个学生准备几个空可乐瓶,结合教学内容适时让学生在教师的指导下做一做、想一想,不仅生动、直观、可信,也培养了学生的动手动脑能力。此教(学)具可以做的实验很多,现试举几例。
The conditions for running schools in rural middle schools are relatively weak. If teachers and students can make full use of teaching aids and teaching aids that are vivid, visual, intuitive, and easy to implement, they can receive the same results as the laboratory. Here we recommend a physics teaching device that is readily available at no cost. It is a cylindrical Coke bottle. The teacher can make each student prepare several empty Coca-Cola bottles. In combination with the teaching content, students can do a job and think about it under the guidance of the teacher at the right time. It is not only vivid, intuitive, and credible, but also cultivates the students’ brain skills. There are many experiments that this teaching (study) can do. Now we will give a few examples.
