The open experimental teaching design for the spectrophotometric detection of promethazine
In order to cultivate students'scientific research accomplishment and practical innovation ability,an open experimental teaching method based on detection of promethazine was designed by using spectrophotometry.The experimental teaching method includes five core processes:experimental skill training,experimental scheme design,experimental operation and instrument operation,data processing,and report summary.The research shows that the open experimental teaching method can not only effectively improve the students'practical operation ability,innovative thinking ability and scientific research accomplishment,but also increase the students'understanding of theoretical knowledge and the ability to solve practical problems flexibly with the learned knowledge.Therefore,the open experiment teaching method can be used as a reference for the reform of science experiment teaching.
