化学是一门以实验为基础的学科,实验在培养学生的观察能力、动手能力、创造能力等方面有着重要作用,因此,历年化学高考题目都侧重于对实验能力的考查,这充分说明了高考的正确的导向功能。体现在高考试卷上,设计实验方案或评价的试题就比较多。从内容上看,有为了达到一定目的的实验操作顺序的设计,有验证某一化学原理的设计,有测定浓度的设计,有分离提纯的设计,等等。从考查的方式上看,有的
Chemistry is an experiment-based discipline. Experiments play an important role in cultivating students’ observation ability, hands-on abilities, and creative abilities. Therefore, the topics of chemistry college entrance examinations over the years have focused on the examination of experimental abilities, which fully demonstrates the college entrance examination. The correct orientation function. It is reflected in the high test volume, and there are many test questions for designing experimental programs or evaluations. From the content point of view, there are designs for the sequence of experimental operations to achieve a certain purpose, designs that verify a certain chemical principle, designs that measure concentration, designs that are separated and purified, and so on. From the way of examination, some
