“化学反应中的热效应”贯穿于整个高中化学的教学过程,其中一些有关的概念和计算是学生在一轮复习中遇到的难点。二轮复习是高三总复习中最见成效的环节,如何抓好这一阶段的教学,对提高复习质量有举足轻重的作用。我的思路是要在一轮复习的基础上寻 The “thermal effects of chemical reactions” throughout the chemistry of high school teaching process, some of the concepts and calculations related to the students in a review of the difficulties encountered.
