王沛清老师编著的《中学物理教学中容易混淆的问题》一书,经修订后,最近由省人民出版社第五次发排付印了。这本书出版两年多来,四次再版,深受读者好评,发行量已达二十六万册。这本书澄清了中学物理教学中种种似是而非和模糊不清的概念,对一些沿袭已久的错误说法,大胆地提出了自己的看法。如力与运动、路程与位移、标量与矢量、速度与加速度、滑动摩擦与滚动摩擦、功和能、振动与波、内能与热量、电势与电压、牵引力和罗伦兹力作功等问题,在教材的基础上都作了深入浅出的分析;有些还抓住教学中的难点或学生最容易混淆的地方,进行了对比研究。全国著名物理学教授葛旭初和湖南师范学院物理系副教授谢泉等对这本书有较高的评价。葛教授在鉴定书上写道:“全书贯穿了辩证的思想方法,分析问题深入浅出,语言清新流畅,颇具特色。”谢副教授认为:“全书观点明确,说理充分,文字流畅,对于广 A book edited by Mr. Wang Peiqing, “Problems Confusing in Physics Teaching in Middle School”, was revised and published by the People’s Publishing House for the fifth time. This book has been republished four times since it was published more than two years ago and has been well received by readers. The circulation has reached 260,000 copies. This book clarifies the plausible and ambiguous concepts of physics teaching in middle school. He boldly put forward his own views on some long-standing mistaken statements. Such as force and movement, distance and displacement, scalar and vector, speed and acceleration, sliding friction and rolling friction, work and energy, vibration and wave, internal energy and heat, potential and voltage, traction and Lorentz force work, etc. On the basis of the teaching materials, they have made simple and easy-to-understand analysis; some have also grasped the difficulties in teaching or where students are most likely to be confused and conducted comparative studies. Well-known national physics professor Ge Xuchu and Associate Professor of Physics Department of Hunan Normal University Xie Quan have a high opinion of this book. Prof. Ge wrote in the appraisal: “The book runs through dialectical thinking and methods. It analyzes the problems in simple language and the language is fresh and fluent. It is unique.” Professor Xie believes: “The book has a clear point of view, full reason, smooth text, and wide
