等效平衡问题是高二化学教学中的一个难点,涉及这类问题的习题、考题也很多,并常考常新,让历届学生感到很头痛。经过深入调研及分析,我认为除了这部分内容本身较抽象外,还与很多教师在教学原理上没讲透有很大关系,造成许多学生只是死记硬背,结果拿到具体习题不会用等效平衡原理进行分析。针对这种现状,我在教学中的策略是讲透原理、注重总结、强化练习,从 The problem of equivalent balance is a difficult point in the chemistry teaching of sophomore year. Problems related to these kinds of questions are covered by a lot of questions and tests are often taken as new ones, so that previous students feel a headache. After in-depth research and analysis, I think in addition to this part of the content itself is more abstract, but also with many teachers did not say much about the teaching principle has a lot to cause many students just rote, the results do not get used to specific exercises Effective balance principle analysis. In response to this situation, my strategy in teaching is to thoroughly understand the principle, focus on summary, and strengthen practice, from
