新编高中化学第一章《化学反应及其能量变化》(人教版),与以前的旧教材比较,编排上更为合理,更为科学。因为这一章内容对高中化学而言,是起着“纽带”的作用,同时它也是高中化学的重点内容。教材中的内容可以说贯穿于高中化学教材的始终,是学生学会化学知识的有力保障,因为其中的理论和概念也是整个高中教学之重点。为此,学会本章内容是至关重要的。
The new high school chemistry chapter “chemical reaction and its energy changes” (PEP), compared with the previous old teaching, the layout is more reasonable and more scientific. Because the content of this chapter plays a role as a “link” for senior high school chemistry, and it is also a key content of high school chemistry. The content of teaching materials can be said throughout the high school chemistry textbooks, is a powerful guarantee for students to learn chemical knowledge, because of which the theory and concept is also the focus of the entire high school teaching. For this reason, learning this chapter is crucial.
