传统的中学化学实验大多以验证性为主,由此招致不少的批评。许多人主张应将验证性实验改为探索性或研究性实验。其实,验证性实验和探索性、研究性实验各有不可替代的作用,关键是如何有效地发挥它们的功效,不管哪种形式的实验都可以有创新的设计。中学化学实验设计的常用方法有以下几种。一、缺陷改进法缺陷改进法指通过发现现有实验的缺陷,把现有实验的缺陷进行改革或革新的方法。改进首先是发现问题,而创新就是要解决现有的问题,每发现一个缺
Most of the traditional middle school chemistry experiments are mainly based on verification. This has led to many criticisms. Many people advocate that verification experiments should be changed to exploratory or research experiments. In fact, confirmatory experiments and exploratory and research experiments all have irreplaceable effects. The key is how to effectively exert their effects. No matter what kind of experiments can be innovatively designed. There are several common methods used in the design of middle school chemistry experiments. First, the defect improvement method The defect improvement method refers to the method of reforming or innovating the defects of existing experiments by discovering the defects of existing experiments. The first improvement is to find problems, and innovation is to solve existing problems and find every one
