新课程理念的构建对高中化学教师提出了更加严格的要求,主要表现在教师要在化学基本概念、基本原理、规律以及化学实验所占的教学时间做到充分的了解,在化学教学中教师留给学生做习题的时间有限。但是习题课教学在整个化学教学中具有极其重要的作用。习题教学一方面能帮助学生搭建思维平台,教会学生总结解题规律,掌握解题思路和方法,另一方面它能够加深学生对书本知识的理解,联系实际培养学生分析问题、解决问题的能力。因此,在有限的课堂时间内把化学习题课教学功能进行充分的发挥,实现化学习题课的高效性显得尤为重要。下面就自己在化学教学中的教学成果与心得与同行分享。
The construction of the new curriculum concept puts forward more stringent requirements for senior high school chemistry teachers, mainly in that teachers should fully understand the basic concepts of chemistry, basic principles, laws and teaching hours occupied by chemistry experiments, and teachers should stay in chemistry teaching Exercise time is limited for students. However, the teaching of exercises in the entire chemistry teaching has an extremely important role. On the one hand, the exercises can help students build a platform for thinking, teach the students to summarize the law of solving problems, grasp the problem-solving ideas and methods, and on the other hand, it can deepen the students’ understanding of the book knowledge and cultivate their abilities of analyzing and solving problems with the actual students. Therefore, in a limited class time, it is very important to give full play to the teaching function of chemistry exercises and realize the efficiency of chemistry exercises. The following on their own chemistry teaching teaching achievements and experiences with peers to share.
