Design And Implementation Of Network Teaching System Based On Data Mining Technology

The main direction of education reform and development in the 21 st century is education informatization.The use of information technology to improve the efficiency of teaching and learning and to cultivate students' practical and innovative abilities is the ultimate goal of education.Network teaching uses the network teaching system as a carrier to break the traditional closed teaching environment and break through the limitations of time and place,so that teachers or students can make full use of excellent educational resources.Designing an online teaching system that conforms to the 21 st century informatization education plays an important role in the improvement of curriculum construction and teaching quality.The network teaching system is a convenient and effective way to implement network teaching.Based on the analysis of the development status of network teaching systems at home and abroad,this paper designs and implements a universal network teaching system.This paper introduces the research background of network teaching system and the research situation at home and abroad,lists the relevant theoretical knowledge and key technologies used in the network teaching system,and expounds the mature analytical design tools such as Visio and Rose.The network teaching system of this paper uses J2 EE architecture and SQL Server 2008 as the main development platform and database tools.The system adopts three-tier architecture.Through the analysis of the functional requirements and non-functional requirements of the system,the system is designed into three main functional modules: infrastructure module,online exam and development evaluation module,and online classroom and interactive answering module.The whole system is based on data mining technology.The classification rules and association rules in mining technology are introduced.The data of students' grades are analyzed by association rules,and the results are verified and summarized by relevant data.These functions of the platform provide teachers with a better teaching method.Teachers have functional modules such as online Q&A,online publishing assignments,and online classes.They also provide students with better learning conditions so that teachers and students can communicate and interact online via the Internet.To jointly complete the study and teaching tasks of this course.The system is designed in strict accordance with the software engineering specifications.After repeated modification and testing,the performance and indicators of the test results are in line with the system design requirements.The system meets the requirements of the network teaching system for the construction of educational information in the 21 st century.
