化学教学中的拦路虎,绊脚石就是化学方程式的学习。如何在化学教学中突破这个难点,翻越这个“分水岭”。首先,合理备课,注重引导,分割切块把知识细化。其次,克服学生畏难情绪,通过激励和适时的赞扬来解决学生的心理压力。最后在生活和教学中把化学方程式贯穿始终,使学生触类旁通让学生逐步迈过这个“分水岭”。 Chemistry stumbling block, stumbling block is the study of chemical equations. How to break through this difficult point in chemistry teaching and to cross this “watershed ”. First of all, a reasonable lesson preparation, pay attention to guide, split the cut to refine the knowledge. Second, to overcome the fear of students, through the encouragement and timely praise to solve the psychological pressure on students. Finally, in the life and teaching of the chemical equation throughout, so that students can learn by analogy for students to step through the “watershed ”.
