高中化学是一门自然科学,在教师设计与引导下的实验教学,具有目的性、探究性、直观性等特点,能够为相关的化学原理提供大量的实验事实,使学生在实验事实中对化学物质及其变化规律,有一个从感性到理性的认识及升华.一、实验教学的问题概述目前,高中化学的实验教学,存在着一系列的问题,致使实验教学积重难返,不利于学生主体性学习地位的体现,严重制约了学生科学素养的提高.1.实验教学的规范性有待提高
Chemistry in high school is a natural science, experimental teaching under the teacher’s design and guidance, with the characteristics of purpose, inquiry and intuition. It can provide a large number of experimental facts for the related chemical principles and enable students to experiment with the chemistry Material and its variation, there is a sensibility to rational understanding and sublimation.A overview of the problem of experimental teaching At present, experimental teaching of high school chemistry, there are a series of problems, resulting in relentless return of experimental teaching is not conducive to students’ subjective learning The manifestation of status has severely restricted the improvement of students’ scientific literacy.1 The standardization of experimental teaching needs to be improved
