提高化学教学合格率一直是教学工作中一个老大难问题,特别是初三年级考试科目多、难度又大,无形中增加了很多困难。化学在初三作为一门新课,提高合格率尤其困难。笔者在提高合格率方面采取了一些措施,取得了一定的效果。一、让学生树立信心、抓好开头教学每次新学期开学,对于进入初三的新生,首先要帮助他们树立学好化学的信心。对于序言课要精心准备,提高学生对于化学的兴趣。并且在教学中一定给学生一个印象:化学比较简单而且有趣实用。在知识点的呈现方面尽量分散,不要给学生一个“化学很难懂”的印象。特别是开学三周内知识点不多也不深,应该尽 Improving the rate of passing chemistry teaching has always been a chronic problem in the teaching work. In particular, there are many subjects of examination in the third grade which are extremely difficult and make many difficulties invisibly.
