General education instruments are the basic material conditions for running schools. In subjects based on experimentation, the use of teaching instruments can reproduce natural phenomena and elevate students' understanding of natural laws from sensory to rational, which is a necessary path for learning. Teaching instruments play a major role in developing students' intelligence, cultivating their creativity, establishing scientific thinking, improving their cognitive abilities, and fostering their hands-on skills.
General teaching instruments include two types of teaching tools: physical and visual aids. In terms of the scope of instruments, the connotation of teaching instruments is much broader than that of general instruments. In addition to simple instruments, teaching instruments also include a large number of models, specimens, sections, chemicals, glassware, and so on.
