作为传统的自然学科,实验是学习和探究化学的重要手段和方法,以实验为基本手段让学生通过观察和实践来认知化学知识生产和发展的过程是化学教学必不可少的环节。化学实验同时在培养学生自主探究和创新能力上更是起着不可替代的作用,从一线教学的角度,对怎样通过实验教学来完善和提升课堂效率进行探索与研究。 As a traditional natural science, experiment is an important means and method of learning and exploring chemistry. Experimenting as a basic measure enables students to recognize the production and development of chemical knowledge through observation and practice as an essential part of chemistry teaching. At the same time, chemistry experiment plays an irreplaceable role in cultivating students’ self-exploration and innovation ability. From the perspective of first-line teaching, it explores how to improve and improve classroom efficiency through experimental teaching.
