Abstract STEM education emphasizes the integration of science, technology, engineering and mathematics. The article discusses the teaching path of STEM education from the characteristics of the disciplines and the internal connections between disciplines. Based on analyzing the connotation and function of prototype introduction, model construction, product design and production, the article constructs the STEM teaching model of “Prototype-Model-Product” (PMP). The article designs a case with “the manufacture of hydrogen car” as an example. By a series of teaching activities from prototypes to models to product prototypes, students could have the chance of being put in a real learning situation which would help to integrate the real life, scientific knowledge, technical design, engineering and manufacture.
