为了给学生创造一个轻松、愉悦的学习氛围,激发学生主动学习,创设情境是非常重要的。一、通过多媒体与实验相结合,创设情境,引导探究课题“利用化学方程式的简单计算”枯燥乏味,而将计算与社会生活联系起来又是化学计算的落脚点。本节课我是这样引入新课的:用多媒 In order to create a relaxed and enjoyable learning environment for students, it is very important to inspire students to actively learn and create situations. First, through the combination of multimedia and experimentation, we create contexts and guide the exploration of topics such as “using simple calculations of chemical equations” to be tedious, while linking computation to social life is the fate of stoichiometry. This lesson I introduced a new class this way: use multimedia
