初中化学是启蒙学科,是九年义务教育阶段的素质教育,主要要求学生掌握简单的化学知识、基本化学实验技能、简单化学计算及化学在生产、生活及国防上的某些应用。由于学生对生活体验不够,连基本的生活现象都不了解,缺乏生活经验,导致在化学学习过程中难以从现象上升到本质,教学难度大,学生难理解,而小学科学恰好可以弥补这一不足。研究切实有效的方法,做好小学科学与初中化学教学的有效衔接,可以提高初中学生的化学学习能 Junior high school chemistry is the discipline of enlightenment, which is a nine-year compulsory education quality education, mainly requiring students to master simple chemical knowledge, basic chemical experiment skills, simple chemical calculations and chemistry in production, life and national defense of some applications. Because students have not enough experience of life, they do not even know the basic life phenomena and lack of life experience, which makes it difficult to ascend from phenomenon to essence in the process of chemistry study. It is difficult to teach and hard to understand students. However, primary science can make up for the deficiency . Studying practical and effective methods to effectively connect elementary and junior high school chemistry teaching can improve the chemistry learning ability of junior middle school students
