Using the CDIO engineering education concept as a reference,the experiment was reformed in four aspects to transform the simple confirmatory experiment into a comprehensive experiment.First,Conceive the experimental system related to the major.The adsorption of tetracycline hydrochloride by Graphene oxide was substituted for the adsorption of activated carbon in acetic acid,which enhanced the professional and social significance of the experiment.Second,Design an experimental plan comprehensively.It is helpful to improve the operability of the experiment and the stability of the experimental results.Third,Implement the students'autonomous and controllable experiment process.It is useful to improve students'experimental initiative and scientific thinking.Finally,Operate a scientifically and reasonable experimental process.While focusing on experimental operation,students are guided to use relevant theoretical knowledge to solve experimental problems,in order to combine the theoretical and experimental knowledge,and further improve the teaching effect of experimental lessons.
