物理教学,应为学生创设良好的物理环境,决不能把物理课变成“第二数学”.更不能把学生引进“题海”的深渊.德国初中物理课本全书编了343个实验.除少数由教师完成的演示实验外,绝大多数是可用简单易找的器材.由学生来完成的低成本实验(即简易实验).其实我国也有很多人积极主张并大力开展简单易行的低成本实验.众所周知,“瓶瓶罐罐当仪器,拼拼凑凑做实验”是已故朱正元老教授的至理名言.20多年前曾成为一个响亮的口号,风行全国,促进了实验教学的开展.
Physics teaching should create a good physical environment for students and must not turn physics into “second mathematics.” It is even more difficult to introduce students into the abyss of “sea of questions”. The German textbook for junior middle school physics textbooks has compiled 343 experiments. Most of the demonstrations completed by teachers are easy-to-find devices. Low-cost experiments (ie, simple experiments) are performed by students. In fact, many people in China actively advocate and vigorously implement simple and low-cost experiments. As we all know, “The bottle, jar and jar were used as instruments to make experiments.” It is the reasoning of the late Professor Zhu Zhengyuan. More than 20 years ago, it had become a resounding slogan, popular throughout the country, and promoted the development of experimental teaching.
