《中学化学教学大纲》指出:化学实验可以帮助学生形成化学概念,理解和巩固化学知识,培养学生观察现象,分析问题、解决问题的能力。中学化学课是一门自然学科,它的教学内容和实验息息相关。通过实验培养学生的化学实验技能是整个教学环节中的重要一环。由于应试教学的影响,在过去一段时间内比较注重学生理论知识的教学,而对化学实验技能的培养重视不够。近几年随着教育改革的深化和发展,全国各地也兴起了以实验为主的实验调演、拍摄实验录像、实验教具评比和开设第二课堂等一系列实验竞赛活动,有力地促进了理论与实际相结合,培养了学生实事求是的学风,树立了科学地探讨问题的风气。
“Chemistry Teaching Syllabus for Middle School” points out: Chemistry experiment can help students form chemical concepts, understand and consolidate chemical knowledge, develop students' ability to observe phenomena, analyze problems and solve problems. High school chemistry class is a natural discipline, its teaching content and experiments are closely related. It is an important part of the whole teaching process to cultivate students' chemistry experiment skills through experiments. Due to the impact of exam-oriented teaching, more attention has been paid to the teaching of students' theoretical knowledge in the past period, but less attention has been paid to the cultivation of chemical experiment skills. In recent years, along with the deepening and development of education reform, a series of experimental competitions such as experimental rehearsal based on experiments, shooting experimental videos, experimental teaching aids, and setting up a second classroom have also emerged in various parts of the country, effectively boosting theoretical and The actual combination of training students to seek truth from facts, establish a scientific style of exploration issues.
