数字教育时代高职学校实训课堂管理系统及考核方法OA

Promoting the reform and innovation of education and teaching with digital technology is an important force for the modernization of education in China.Against the background of digital education,the training classroom management system and the training assessment methods in higher vocational colleges have become one of the important topics discussed.A training classroom management system based on an embedded platform can assist teachers in achieving efficient training classroom management.An embedded system with interconnection between the teacher machine and the student machine is adopted as the minimum system of the traning classroom system.The ITOP 4412 embedded development platform equipped with the Samsung Exynos 4412 microprocessor chip is used as the hardware platform of the embedded device.The Android operating system is ported on the platform,and applications are developed with the Android studio development platform to develop applications to complete the software and hardware configuration of the system.Based on the teaching historical data,the information entropy and information gain rate of each attribute data of the training classroom are calculated with the C4.5 decision tree algorithm.Attributes with an information gain rate higher than the average value are sorted in descending order,and the training task classification and assignment model as well as the training guidance right model are established accordingly.Based on this structure,the training assessment model integrates the task complexity,training guidance,training teacher scoring and other factors in the training classroom,and a comprehensive assessment method for students' training classroom performance is proposed.Practice has proved that after the model and assessment method are applied to the course Electrical and Electronic Technology for 5 consecutive years,the average accuracy rate of students and other indicators have steadily improved.Especially in 2019,compared with 2018,the comprehensive excellent rate of training and assessment of automation students' Electrical and Electronic Technology has increased by 55.4%.The training classroom management system and assessment methods have the advantages of simple operation,strong theory,high efficiency and practicality.
