化学是高中理科三大主科之一,是理科高考考试的重要组成部分,所占分数比例也很大。因此,对于高中理科生来说,学好化学意味着在高考中占据了一定的优势。然而,笔者作为一名高中化学教师,在教学过程中却发现,部分学生的化学成绩总是不好。究其原因,他们自己认为,化学很难学,要记要背的东西太多,重点也不好把握,而自己的时间、精力有限,如果把更多的时间花在对化学公式、化学反应等的记忆上,势必影响对其他学 Chemistry is one of the three main subjects of high school science, is an important part of science college entrance examination, a large proportion of points. Therefore, for high school science students, learning chemistry means taking a certain advantage in the college entrance examination. However, as a high school chemistry teacher, I found in the teaching process that some of my students are not good at chemistry. The reason, they think, chemistry is difficult to learn, remember to back too many things, the focus is not good to grasp, but their own time, energy is limited, if more time spent on chemical formulas, chemical reactions And so on the memory, is bound to affect other learning
