化学是一门以实验为基础的学科.受应试观念影响,在高中化学教学中,化学实验大多是教师演示学生看,操作性实验较少,学生没有通过实验获得化学知识的构建.在高中化学教学中,教师要结合学生的学习实际和化学实验的特点,从仪器、方法和过程等方面创新化学实验.一、因地制宜,创新实验仪器实验教学,重在让学生通过实验而获得对化学知识的理解,但从传统化学教学中的实验教学来看,教师重演示实验而轻操作实验,甚至直接告诉 Chemistry is an experiment-based discipline affected by the test concept, chemistry teaching in high school, most of the chemistry experiments teachers look at the students to see, less operational experiments, students did not get the chemical knowledge through experiments in the construction of high school chemistry In teaching, teachers should innovate chemistry experiments from the aspects of instruments, methods and processes according to the students’ learning reality and the characteristics of chemical experiments.First, according to local conditions, the experimental teaching of experimental instruments should be innovated so as to enable students to gain knowledge of chemistry through experiments Understand, but from the experimental teaching in the traditional chemistry teaching, the teacher re-demonstrates the experiment and the light operation experiment, and even directly tells
