化学现象由内及外地表现出来,使得学生个体在认识和识别上存在着个体差异性。因此,需要借助合作学习模式来给予克服。通过对合作学习模式进行定位,其模式可从:理清初中化学课程的学科特点、建立科学的合作学习分组模式、完善合作学习模式的教学管理、形成合理的教学效果评价机制等四个方面进行构建。 The chemical phenomena are manifested both inside and outside the country, which makes the students have individual differences in cognition and identification. Therefore, it needs to be overcome through the cooperative learning model. The mode of cooperative learning can be identified from four aspects: clarifying the characteristics of the junior high school chemistry curriculum, establishing the scientific cooperative learning grouping mode, perfecting the teaching management of the cooperative learning mode and forming a reasonable teaching effect evaluation system Construct.
