Abstract: SPOC teaching model is a product of the post -MOOC era，which reduces the high loss rate of MOOC teaching model and avoids the maladjustment of the students caused by flipped classroom. Thus，more and more schools and teachers are trying to use SPOC teaching model which plays a more important role in experimental teaching field. In this paper，guide maps，such as preview guide，principle map，step map，report guide map，are used in the SPOC teaching reform to simplify the digestion of principle process for students，improve the interest of study，standardize the experimental procedures and promote the in-depth discussion. After practice，it is proved that this scheme improves the effect of the learning preview and the understanding of operation process. Meanwhile， part of the students’experiments is expanded and some good results are achieved. The implementation of this idea should be a reference for the other courses，especially for experimental courses.
