高中化学教学一直以来都难以让学生熟练掌握化学原理并有效运用到实验中去,使得化学教学任重而道远.作为以实验为基础的一门学科,高中化学越来越重视学生的实验能力.为了促进新教材的应用与实施,让学生能在更有效的实验中提升自身综合能力,结合自身教学实践,在此对高中化学新教材的练习进行研究与探讨.在高中化学的教学过程中,课堂练习发挥着不容忽视的作用.通过一系列以练习为主的课堂教学,教师能够从中培养学 High school chemistry teaching has always been difficult for students to master the chemical principles and effective use of the experiment to make chemistry teaching a long way to go.As a laboratory-based disciplines, high school chemistry more and more emphasis on experimental ability of students In order to promote the application and implementation of new teaching materials and to enable students to enhance their comprehensive ability in more effective experiments and to combine their own teaching practice, this paper studies and discusses the practice of new high school chemistry textbooks. , Classroom exercises play a role that can not be ignored.By a series of practice-based classroom teaching, teachers can learn from
