从教师普遍不重视绪言课教学的现状出发,基于对化学反应原理绪言课功能定位的再认识,从分析学生已有的认识化学反应的能力出发,进行了促进学生化学反应认识能力发展的绪言课教学设计及实施,并对素材选择、化学史教学的价值、模型建构等影响绪言课教学效果的问题进行了讨论。 Based on the fact that teachers generally do not attach importance to the teaching of preacher teaching, based on the re-understanding of the functional orientation of preacher teaching of chemical reaction principle, from the analysis of students ’existing ability to recognize chemical reactions, the introduction lesson to promote students’ Teaching design and implementation, and discussed the problems that affect the teaching effect of introduction teaching, such as material selection, the value of chemistry history teaching and model construction.
