Research on online and offline mixed teaching mode—Taking the teaching of single chip microcomputer course of Internet of things engineering as an example

Internet of things engineering specialty has the characteristics of interdisciplinary, wide range of knowledge and focusing on engineering practice. As a professional basic course of Internet of things engineering, Microcontroller Unit (MCU) course should focus on cultivating students' ability of solving practical engineering problems and application innovation. According to the students' cognitive law, the project tasks based on the working process are jointly developed through school enterprise cooperation. The mainstream 32-bit MCU contents are integrated into 16 teaching tasks, 24 teaching contents and 43 knowledge points by calling library functions. From easy to difficult, from simple to complex, the students are taught in accordance with their aptitude through the online and offline mixed teaching mode, and the ability and thinking of solving practical projects are cultivated In order to meet the needs of students' personalized development, we should promote teaching and learning by competition, stimulate students' interest in learning MCU and build up their confidence in learning the perception layer of Internet of things, and cultivate innovative and applied talents with strong practical ability.
