Selfhelp Exercise Platform for Professional Courses Based on Knowledge Points
Student majoring in network engineering LI Jiafeng
Tutor ZHAO Li
Abstract: With the development of computer technology, computer multimedia teaching has gradually occupied the classroom, but studentsafterclass exercises are still in a more traditional stage,such as using relevant textbooks for afterschool exercises ,distributing paper exercises by teachers and so on. Because of the limited number of questions and the emphasis on universality, the above methods can not give students efficient and targeted exercises. Therefore, this paper discusses a selfhelp exercise system for professional courses based on SSH framework. Users can upload test questions freely, establish relevant constraints to organize test papers, conduct selftest and test paper marking. At present, only selfmarking is supported. Compared with the traditional mode of teaching and training, this system can greatly reduce the burden of teachers and ease the immobilization of studentsknowledge training, providing theoretical reference and technical support for the future development of teaching mode.
