中考化学一轮复习时,通常先将课本中的知识点进行梳理整合,查漏补缺。如果在复习时,就是简单的将所学知识进行再现,难免会陷入低效、耗时的复习状态,如何提高课堂效率,值得我们去思考?笔者在复习时进行了尝试,利用学生身边熟悉的物质“冰红茶”作为载体,把“溶液的形成与特征”、“部分溶液的特征颜色”、“饱和溶液与不饱和溶液的转化方法,以及固体溶解度的定量表示方法”融入其中进行复习,充分发挥了学生的主动性和积极性,激发了学生的
In the review of chemistry in the middle school exam, the knowledge points in the textbooks are usually combed and integrated to find out what is missing. If we simply review the knowledge we have learned during the review, we will inevitably fall into an inefficient and time-consuming review. How to improve classroom efficiency is worth thinking about? The author tried to use the familiar knowledge of the students during the review. Substance “Ice black tea” as a carrier, “solution formation and characteristics ”, “partial solution’s characteristic color ”, “saturation solutionunsaturated solution conversion method, and quantitative representation of solid solubility ”Integrating into it to review, give full play to the students’ initiative and enthusiasm, and stimulate students’
