Research And Curriculum Design Of IoT Practical Teaching Platform For The Secondary Vocational Schools Based On CDIO

At present,the demand for IoT application technology talents in various industries in China is gradually increasing.However,the quality and quantity of talent training in secondary vocational education in China is far from the actual demand.The problem of training in the teaching of Internet of Things in the secondary school is particularly prominent.There are mainly problems such as the lack of IoT training platforms and courses,weak teachers,and weak comprehensive ability of students.Therefore,researching and designing the training platform and curriculum that meets the professionalism of the Internet of Things in the secondary school has become an important issue to be solved in the field of secondary vocational education.This paper combines the urgent needs of the practical teaching of the Internet of Things in the middle school.Under the guidance of the CDIO engineering education model theory,this paper studies and develops the IoT training platform and courses that are more in line with the IoT students.The main work is as follows:First of all,this paper uses literature research method,interview method and investigation method to investigate and analyze the status quo of IoT training in secondary vocational schools,and carries out data crawling on the demand of IoT posts.The problems existing in the training teaching,and the specific solutions based on the CDIO concept to develop the training platform and curriculum more suitable for the teaching of the Internet of Things in the secondary school;Secondly,this paper integrates the CDIO concept,taking the smart home project as an example,adopting the classic of the Internet of Things.The sensing layer,the network layer,the application layer framework,the application of sensing detection,ZigBee networking,Java development and other technologies,designed a set of IoT training platform suitable for the IoT professional students to learn,after functional testing and performance testing,to meet the design needs;Again,this paper uses the CDIO engineering education model,experimental teaching method and action research method,and applies the designed training platform to design an IoT training course more suitable for the IoT students in the middle school.A smart home project is divided into several sub-experiments,which are taught by completing sub-experimental tasks,based on CDIO teaching.The model enhances students' basic knowledge,personal ability,teamwork ability,engineering system ability and innovation ability,as well as improving teachers' teaching ability and engineering ability.Finally,this paper adopts experimental research method and CDIO teaching mode to implement the course.After the course is implemented.The students' knowledge,ability and attitude were evaluated,and the students' basic knowledge of the Internet of Things,personal ability,teamwork ability,Internet of Things engineering system ability and Internet of Things innovation ability were improved,and the professional quality of students was improved.The effectiveness of the course.The method proposed by this project based on the CDIO concept to solve the problem of IoT training in the secondary school,and the developed training platform and curriculum more suitable for the teaching of the Internet of Things in the secondary school have a good practical application significance,and also for the future secondary vocational school.The IoT talent training reform direction has made certain contributions.
