美国核化学家西博格说:“化学是人类进步的关键。”一语道破了化学学科的社会价值、化学和人类的关系以及化学的重要性。在教学中,引发学生对化学的兴趣是关键。新课标对初中化学教师提出了更高的要求,教师要不断改善教学形式,使其不拘一格,灵活多样,引起学生的注意力,使教学事半功倍。 US nuclear chemist Siegburg said: “Chemistry is the key to human progress.” The phrase discards the social values ​​of chemistry, chemistry and human relationships, and the importance of chemistry. In teaching, triggering students interest in chemistry is the key. The new curriculum puts forward higher requirements for junior high school chemistry teachers. Teachers should continuously improve their teaching forms to make them more eclectic and diversified, arousing students’ attention and making teaching more effective.
