本文以“燃烧条件”的探究为例,通过在一定情境中扮演角色来组织开展教学,有效提高了课堂效率,增强学生学习化学的兴趣和学好化学的信心.新课程标准明确化学学科的理念是“使每一个学生以愉快的心情去学习生动有趣的化学,激励学生积极探究化学变化的奥秘,增强学生学习化学的兴趣和学好化学的信心”.化学学科最大的特点是和生活实际联系密切,如果能够将这个特点很好地利用到教学实践中,既有利于学生更好地理解课堂的知识, This paper takes the exploration of “Burning Condition ” as an example, and organizes the teaching by playing a role in a certain situation, which effectively improves classroom efficiency, enhances students’ interest in learning chemistry and learns chemistry confidence. The idea is to “make every student happy to learn vivid and interesting chemistry, inspire students to actively explore the mysteries of chemical changes, enhance students’ interest in chemistry and learn chemistry.” The most prominent feature of chemistry is that it is related to life The actual close contact, if we can make good use of this feature into teaching practice, both help students better understand the knowledge of the classroom,
