摘要

With the expansion of Chinese universities, the speed of school introducing new teachers and the construction of experimental classrooms has produced a significant hysteresis quality due to the rapidly growing number of students. Moreover, because the laboratory has higher requirements than the ordinary classroom construction, the supporting hardware is more or the transformation cost is high and the cycle is long, laboratory resources have always been a key factor in limiting student productivity. Under the existing teacher conditions and laboratory conditions, how to mobilize students' sense of autonomy has always been a difficult problem to solve. After a long period of first-line teaching work, a set of practical positioning plate system for laboratory experiment teaching classrooms was explored. Through the humanized design and supporting laboratory operating principles, it can mobilize students' independent consciousness, so that students can get rid of the group psychology, consciously regulate their own experimental behaviors and steps, reduce external disturbances, reduce random movements and misuse of articles, effectively reduce the experimental failure rate and reduce the total duration of experiments.
