ABSTRACT
The hierarchical structure showed in Figure 1 is very much like the architecture of Internet of things. Or it can be said that the hierarchical structure is an object of Internet of things if the abstract hierarchical structure of Internet of things is viewed as a class. The object macroscopically provides an approach for students to know “why it is so” because it has a good progressive structure and teaching content is easy to find its source with it. On the other hand, from the micro-aspect, or from the view of the correspondence between the hierarchical model and the details of teaching content, teching experience has proved that the hierarchical model covers all the details.
