The Research on “Virtual-real Integration, Multi-level Progressive” Practical Teaching: Take the Course “Comprehensive Design and Production of the Internet of Things (Perception Layer)” as An Example
Wenmei Jiang · 2023
The course "Comprehensive Design and Production of the Internet of Things (Perception Layer)" takes the information acquisition system of the perception Layer of the Internet of Things as the design direction, and completes the design and production of the system, including the construction of hardware circuits and the design of control programs. It is a typical offline practical training course. In order to solve the key points of practical courses, such as low classroom utilization, students “fishing in troubled waters”, and offline suspension of classes in epidemic areas, this case has been designed in teaching content, teaching design, and experimental methods to develop a “virtual-real integration, multi-level progressive” teaching model. In terms of teaching content and teaching design, through the route of “basic knowledge → module practice → project actual combat”, and with a more detailed and reasonable evaluation system, students can be guided from shallow to deep, easy first and then difficult, from simple to complex to learn and gradually improve, so as to stimulate students' interest in learning and improve practical innovation ability; In terms of experimental teaching methods, the Tinkercad simulation platform is introduced to implement a “virtual-real fusion” teaching plan. Students can combine the simulation platform with physical production to meet the teaching requirements of “suspension of classes and non-stop learning” during the epidemic, get rid of the limitations of physical components, and ensure that students can complete the design of the circuit and the debugging of the program anyway, and the teaching goals of the course can be achieved.
