Development Of Intelligent Teaching Service System Based On ASP.net

Our school is a vocational and technical school transformed from high school, the information management of which still remains in the single data management level. This results in a backward management system of student achievements, evaluations,employment guidance evaluation and so on. Each department of the school needs their own data. They have a hard time whenever it comes to students’ enrollment, graduation, grades input, performance evaluation and job recommendation. Therefore a complete service system is what we need to integrate, analyze and manage data to provide better service for the students, teachers and teaching.This paper introduces in detail the development process of the intelligent teaching service system with the actual requirement of teaching service in our school, including the requirement analysis, functional design and database design of the system. It can realize the integrated management of students’ grades and provide comprehensive intelligent services for the teachers.Prevent students from dropping out of school is a challenge in the moral education management of vocational school, which is one of focuses of this paper. The dropout rate will greatly reduce with thorough moral education work beforehand, In this matter, the dropout risk index of students is the key. This paper presents an "intelligent" method which gives a student dropout risk warning index based on the correlation matrix method of system evaluation in system engineering. It is practical and easy to use with the weight setting of evaluation index and an evaluation scale.Another key content of this paper is the student employment recommendation system. Based on the historical data of employment, this paper puts forward the analysis method based on C4.5. The recommendation tree we got from this algorithm has high accuracy and comprehensive classification rules. However, the efficiency of this algorithm is so low that this paper has to study the C4.5 algorithm optimizing and improves the execution efficiency of algorithm.The system in this paper is an integrated system, which can not only realize the integrated management of student achievements, but also intelligently get the dropout risk index and employment guidance for the students. The application of the system will greatly improve the level of management and service in teaching, moral education and student employment.
