对教师而言,高中化学内容多、概念多,教学任务重,教学的广度、深度难以把握.对学生而言,高中化学就像一个个谜,解开了,满心欢喜,越学越有意思;解不开,就是一塌糊涂,越学越没兴趣.总之,师生对于化学教学的态度差异较大,化学教学的效果也良莠不齐,难以确保化学教学总体水平的提高.致使化学教学往往花费教师、学生较多的心力,效果却差强人意,教学效率难以令人满意.一、充分认识化学教学的重要性
As far as teachers are concerned, high school chemistry has many contents, many concepts, heavy teaching tasks, and the breadth and depth of teaching are difficult to grasp. For students, high school chemistry is like a mystery, solved, full of joy, and more interesting. In short, teachers and students are more different attitudes towards chemistry teaching, chemistry teaching is also good and bad, it is difficult to ensure the overall level of chemistry teaching to improve .Therefore, chemistry teaching often cost teachers, students More effort, the effect is unsatisfactory, teaching efficiency is unsatisfactory .A full understanding of the importance of chemistry teaching
