Construction And Application Of IOT Security Training System Based On Multi-level Feedback

With the rapid spread of IoT devices,IoT security issues are emerging and facing severe challenges.The training of IoT security talents is imminent,and the training of the IOT talents in the secondary school has a relatively backward training system and insufficient intelligence,the teacher's teaching is not targeted,and the students' cognitive level is low,which affects the students' reality on the Internet of Things.Training interest and enthusiasm.This article will study and build a teaching and training system that meets the needs of current and future IoT and security-related talent development,to help teachers flexibly teach,stimulate students' interest in learning,and enhance learning outcomes.According to the literature research method,this paper studies a multi-level feedback teaching model based on the current advanced teaching theory and teaching methods,and constructs an IoT security training system based on the principle of this model.The Internet of Things security training includes three software systems,namely,IoT training,IoT training management and training services,and an integrated training toolbox.Six types of experiments were designed.Based on the multi-level feedback teaching model,each type of experiment in the training system is divided into four levels: theoretical test,basic experiment,improvement experiment and inquiry experiment.After each level is completed,the problem is fed back to the teacher through the system,and the results and suggestions are fed back to the students and help the students to improve their interest in learning,promote self-reflection,improve the training results,cultivate students' ability to explore and innovate,and help teachers master the students in time.Insufficient training,promote flexible teaching and improve teaching efficiency.Finally,this paper takes the RFIDsecurity course as an example for teaching design,and tries it in a middle vocational school in Ningbo.Through the quasi-experimental research method and interview method,the teaching effect of the system is demonstrated,and the advantages and disadvantages and suggestions for improvement are put forward.According to the results of quasi-experimental research and interviews,it is found that the system has the effect of improving teachers' teaching,stimulating students' interest in learning and improving academic performance.The construction and application of this system will provide support for the construction of the IOT security training system and practical teaching innovation.
