在教学中我们发现,很多初中化学成绩很优秀的学生进入高中后成绩却直线下滑,学习积极性也逐渐减弱。究其原因是因为初中化学教师未找准初高中化学知识的衔接点,导致学生不能充分利用旧知识拓展新知识,从而加大了学习难度。本文就在新课改背景下,如何有效实现初高中化学知识的有效衔接,进行了详细的探究。人教版高中化学中的很多内容均是从初中化学教材的基础上延伸而来的,是对初中化学知识的提升与发展。通过 In the teaching, we found that many students with excellent junior high school chemistry scores have dropped straight after entering high school, and their learning motivation has gradually weakened. The reason for this is that junior high school chemistry teachers have not been able to identify the connection points of junior high school chemistry knowledge, which has led students to make full use of old knowledge to develop new knowledge, thus increasing the difficulty of learning. In this paper, in the context of the new curriculum reform, how to effectively achieve the effective convergence of the chemical knowledge of the junior high school, carried out a detailed exploration. Many of the contents of the High School Chemistry of the People’s Education Press are based on the chemistry textbooks for junior high school students. They are the promotion and development of junior high school chemistry knowledge. by
