在实际教学中,仅靠教材设定的实验有时难以达到理想的实验教学效果。尤其是涉及到微观知识的教学内容,教材无法设定直观实验,但缺少了直观的演示实验,对学习感性知识为主的初中学生来说难以理解,久之易挫伤部分学生的学习兴趣而导致其学业成绩两极分化。若借助多媒体课件进行模拟实验,辅助完成化学实验教学内容,可弥补这种不足,甚至起到事半功倍的效果。
In the actual teaching, experiments based on teaching materials are sometimes difficult to achieve the desired effect of experimental teaching. In particular, teaching contents related to micro-knowledge can not set visual experiments. However, there is a lack of intuitive demonstration experiments, which are difficult for junior high school students to learn perceptual knowledge. For a long time, some students may easily discourage junior students from learning interest. Academic performance polarization. If using multimedia courseware to carry out simulation experiments to assist the completion of chemistry experiment teaching content, can make up for such deficiencies, and even play a multiplier effect.
