兴趣是一个人力求认识某种事物或从事某项活动的心理倾向。因此 ,对于中学生来说 ,兴趣的培养犹为重要 ,化学的学习也是如此 ,如果学生对化学学习缺乏兴趣 ,就会缺乏学习化学的主动性和积极性 ,教学效果可想而知。基于此 ,化学教学要抓住化学是一门以实验为基础的自然科学的特 Interest is a psychological tendency of human beings to understand something or engage in an activity. Therefore, for middle school students, the cultivation of interest is still important, and chemical learning is also the same. If students lack interest in chemistry learning, they will lack the initiative and enthusiasm for learning chemistry, and the effectiveness of teaching can be imagined. Based on this, chemistry teaching should grasp that chemistry is a natural science based on experiments.
