化学实验复习是整个化学总复习中一个非常重要的环节。化学实验复习,关键是根据考试大纲和近年高考实验考查的要求,渗透新课标的理念。一、自主构建有利于掌握实验主干知识的框架1.教师引领学生自主构建实验知识网络实验复习中以构建实验主干知识网络为中心的复习方法,是一种以不变应万变的基本方法。复习中要注意的是,学生头脑中的知识网络是一个主动建构的过程,一定要通过学生的自主活动才能完成,教师不能包办代替,教师的作用是启发、诱导、引领。如一开始复习实验,就发动学生根据“两纲”、新课标和高
Review of chemical experiments is a very important part of the overall review of chemistry. The key to the review of chemical experiments is to penetrate the concept of the new curriculum standard in accordance with the examination outline and the requirements for the examination of the college entrance examination in recent years. 1. Self-constructed framework conducive to mastering experimental backbone knowledge 1. Teachers guide students to build experimental knowledge autonomously The review method based on the construction of the experimental backbone knowledge network in the experimental review of the experiment network is a basic method to adapt to changes. In the review, it should be noted that the knowledge network in the student’s mind is an active construction process. It must be completed through the student’s independent activities. The teacher cannot be replaced by the teacher. The role of the teacher is to inspire, induce, and lead. As soon as the experiment is started, students are motivated to follow the “two outlines”, new curriculum standards and
