实验室是物理学科教学的一个主阵地,但在农村中学,物理实验室建设还存在一些问题。一是实验经费投入少,实验设备陈旧。随着实验教学原理的不断优化,教材上新增加一些演示实验和学生分组实验,以及课后小实验,原有的实验器材已跟不上现代实验教学的需要。虽然在“普九”的推动下,跟踪配备了一些仪器设备,但很多仪器 The laboratory is a main front for physics teaching, but there are still some problems in the construction of physics laboratory in rural middle schools. First, less experimental funding, laboratory equipment obsolete. With the continuous optimization of the experimental teaching principle, some demonstration experiments and student group experiments have been added to the teaching materials, as well as small experiments after class. The original experimental equipment can not keep up with the needs of modern experimental teaching. Although the “Pu nine ”, driven by the track equipped with some of the equipment, but many instruments
