在初中化学教学中开展学生积极主动提问的教学方式,以及情景式等新的教学方式,可以提高学生学习的效率,并且能培养学生的思考能力和创新精神.初中这个阶段的学生学习任务重,学习压力大,如果以枯燥的教学方式进行教学活动,就提不起学生的学习兴趣,在无形中就给学生增加了压力.相应的在化学的解题过程中也要寻求更好的解题方法,快捷推断物质法就是一种科学有效的方法. In the chemistry teaching of junior high school, students’ active and active teaching methods, as well as new teaching methods such as situational style, can improve the efficiency of student learning, and can cultivate students’ thinking ability and innovative spirit. In this stage of junior high school students have heavy learning tasks. The pressure of study is great. If we use boring teaching methods to carry out teaching activities, we can’t afford students’ interest in learning. This will increase the pressure on students virtually. We must also seek better solutions in the process of solving problems in chemistry. Method, rapid inference material law is a scientific and effective method.
