我教化学这门课已经十八年了.同学们对我教课的反映是听得懂,记不住,分不清.我常常为此而苦恼,但始终没有得到解决。直到最近才找出了造成这种情况的原因,主要是由于我的老一套旧教学思想在作怪,旧教材本身存在着内容浅,烦琐、重复、割裂、脱离实际等缺点,而我在教学方法上又是管教不管导,管课内不管课外,无的放矢,平辅直叙,因此就不能收到较好的效果。但我过去对这老一套却有了感情,成了习惯,认为这是天经地义、不能变动的,从没有想到有改革的必要。到学习了有关教学必须改革的文件后,提高了认识,在教学实践中,对改进教学方法方面进行了试验,获得了较好的效果,改变了以前学生对化学知识记不住、分不清的情况。例如过去学生对钠与氯化铜 I have been teaching chemistry for 18 years, and my classmates have been able to understand, remember and tell from my teaching, and I often get distressed but never solve it. Until recently, the reasons for this were found mainly due to the misunderstanding of my old set of old teaching thoughts, the shortcomings of shallow, cumbersome, repetitive, fragmented and out of practice in the old teaching materials, and my teaching method Regardless of discipline, despite the extracurricular activities in the management of the course, it is neither a target nor a plain one, so it can not receive good results.

To learn about the teaching reform must be improved after the file, raising awareness, in teaching practice, to improve the teaching methods were tested, obtained good results, changed the previous students can not remember chemical knowledge, can not distinguish between Case. For example, past students of sodium and copper chloride
