在高中化学教学中,必不可少的就是案例分析,利用案例设计特定的课堂情境,学生通过对案例的兴趣转化为对化学理论学习的积极参与,从而主动的来分析、思考、推理、解决其中的化学问题,以提高学生的化学知识理论和方法技能.可见,案例教学的实施很好的强化了学生的主体地位,使学生从层面到实质都有了一个很好的认识.然而案例教学的效果又离不开教师的精心预设,教师只有深入的整合教辅材料;结合学生的各中生成来编制最佳案例;使学生主动的体验到化学知识的演 In high school chemistry teaching, it is essential to analyze the case, use the case to design a specific classroom situation, students through the interest of the case into active participation in the study of chemical theory, so as to take the initiative to analyze, think, reason and solve Of the chemical problems in order to improve the student’s knowledge of chemistry theory and method skills can be seen that the implementation of case teaching is a good reinforcement of the student’s dominant position so that students have a good understanding of the level to the essence.However, The effect is inseparable from the teacher’s meticulous preconditions, teachers only in-depth integration of supplementary materials; combined with the student generated to prepare the best case of all; make students take the initiative to experience the chemical knowledge
