高考对学生实验探究、分析能力的考查已经越来越重要。“分析、比较、优化和改进”的过程,就是分析问题、解决问题的过程,而对比性实验的考查就是对学生分析问题解决问题能力考查的重要体现。对比性实验的考查主要分为两种,即实验装置设计的对比和实验方案设计的对比。无论哪种考查,只要抓住解决问题的钥匙,问题就会迎刃而解。对比性化学实验问题的解决可
It has become increasingly important for the college entrance examination to examine students’ experimental exploration and analysis capabilities. The process of “analysis, comparison, optimization, and improvement” is the process of analyzing problems and solving problems. The examination of comparative experiments is an important reflection of students’ ability to analyze problems and solve problems. The examination of comparative experiments is mainly divided into two types, that is, the comparison between the experimental device design and the experimental design. No matter what kind of examination, if you grasp the key to solve the problem, the problem will be solved. The solution to the problem of comparative chemistry experiments can be
