摘要
新课程化学教学呼唤实验创新,教师在教学中遇到教材中不理想的实验设计,就需要自己动手,进行实验装置创新,创新往往是针对某一具体实验问题的,因此具有较强的独立性。同一问题往往又有多种解决的方法,因此,实验装置创新又存在着多样性和灵活性,主要有三法:替代法、组合法、增减法。
New curriculum of Chemistry Teaching for experimental innovation,teachers meet experimental design is not ideal in the textbooks in teaching,you need to do it yourself,innovation experiment,innovation is often for a specific experimental problem,so it has strong independence.There are many ways to solve the same problem.Therefore,there are many kinds of flexibility in the innovation of the experimental device.There are three main methods:substitution method,combination method,increasing or decreasing method.
