化学是一门以实验为主的自然学科,许多化学概念、原理都是通过化学实验得到的,因此,加强化学实验教学是提高化学教学质量的重要手段。但是,对于我们农村落后山区学校来说,尽管学校配备了一些实验仪器,但是由于人力资源、实验仪器不齐 Chemistry is an experiment-based natural science. Many chemical concepts and principles are obtained through chemical experiments. Therefore, strengthening chemical experiment teaching is an important means to improve the quality of chemistry teaching. However, for our rural backward mountain schools, although the school is equipped with a number of experimental equipment, but due to human resources, experimental equipment missing
