随着新课程改革的不断发展,高中化学的教学应该达到更高的水平,尤其是运用合理、快速方法进行解题,从而有效提高课堂效率.为此,教师需要改变传统落后的解题思路,探讨能够提高高中化学解题效率的新方法.本文从“化合价”的巧用这个方面进行探讨,以期为高中化学解题效率提升带来启示.化合价在高中化学的教学中占据重要地位,其贯穿了化学知识的各个方面,无论是正确表达化学式,还是进行化学计算,其作用十分显著.但是,在传统的高中化学 With the continuous development of new curriculum reform, high school chemistry teaching should reach a higher level, especially the use of reasonable and rapid methods to solve problems, so as to effectively improve classroom efficiency. To this end, teachers need to change the traditional backward problem-solving ideas. To explore new ways to improve the efficiency of high school chemistry problem solving. This article explores the use of “valence ” in order to bring enlightenment to the efficiency of high school chemistry problem solving. Valence plays an important role in the teaching of high school chemistry. It runs through all aspects of chemical knowledge, whether it is the correct expression of chemical formulas or chemical calculations, its role is very significant. However, in traditional high school chemistry
