对于高中化学教材而言,贯穿于其中的一个最为重要的主线就是氧化还原反应,可以说,有超过90%的化学知识均会涉及到氧化还原的有关知识.同时,氧化还原的有关知识也是历年高考的一个重要考点.因此,在实际的高中化学教学过程之中,氧化还原这个知识点也是一个教学的难点与重点.由此可知,这一章的教学质量的好坏将直接影响到学生对化学其他知识点的理解.笔者认为,对于这个知识点的教学,应该从基本概念出发,这主要是由于其中抽象的概念较多,对基本概念掌握
For the high school chemistry textbook, one of the most important threads that runs through it is the redox reaction. It can be said that more than 90% of the chemical knowledge is related to the redox knowledge. Meanwhile, the knowledge of redox is also the calendar year Therefore, in the actual high school chemistry teaching process, the knowledge of redox reduction is also a teaching difficult and important point.Thus, the quality of teaching in this chapter will have a direct impact on the students’ Chemical knowledge of other points of understanding.In my opinion, for the teaching of this point of knowledge, we should proceed from the basic concepts, which is mainly due to the concept of more abstraction, grasp of the basic concepts
