物理学是一门以实验为基础的科学,因而物理实验对重难点的突破、教学效果的好坏、教学效率的高低都会产生关键性的影响.在八年级物理(上)第四章第8节《走进彩色世界》(教科版,其他版本教材及高中物理教材中也有类似的内容)中,教材内容体系围绕日光色散与太阳光谱展开,因而光的色散实验是该 Physics is an experiment-based science, so physical experiments on the heavy and difficult breakthroughs, teaching effectiveness is good or bad, the level of teaching efficiency will have a crucial impact.In the eighth grade physics (on) Chapter IV, Article 8 Festival “into the color world” (textbooks, other versions of textbooks and high school physics textbooks also have similar content), the textbook content system around the solar dispersion and the solar spectrum, so the light dispersion experiment is the
