| Ministry of Education in China has devote great efforts to developing online education since 1999, which has become the new growing point in development of today's education technology and the direction of the main trend in the development of modern education. There are several common shortages in today's online education, such as monotonous teaching pattern, accumulation of teaching resources in a casual way, and intelligence of low level. There is also great difference among learners in several aspects, such as the learning ability, the personal interests and habits, the foundation of learning, and the level of devotion to study, which lead to the situation that the system of online education is not suitable for the individual need.This essay, which is based on Web mining techniques, makes a research on the issue of individual service in online teaching. The major work which is carried out includes:1.Introduction about the present situation and problems of distance learning and teaching system; study on the situation of individual education and the standards of distance learning; exposition on the research meanings and the idea about how to solve the problems in individual teaching and learning, which is to improve the system of distance education by using the Web mining techniques, along with the standards for distance education, to express the"learners-centered"teaching thought, and to realize the actual resource-sharing.2.Introduction of data mining techniques and Web mining techniques; discussion on the data model and structure of Web using and mining; and analysis on the Connection rule excavation algorithm and improvement algorithm。3.Advancing the model of individual teaching and learning system, enlarging the learning system of the traditional online teaching conditions, so that online education will suit the features of different learners by developing contents for each individual. The model has the feature that there are two nearly parallel mining processes to mine the Visit diary and Interactive data respectively. There is also an exposition on the Web mining process in this model using the methods of data mining.4.Proposing the key sub model by which we make up the individual teaching and learning model——OLPR, which is also the core part of this essay. This model is described as online part and offline part. The offline part consist of the data preparation and specific task of Visit mining , which is to develop The homepage gathers the kind by Gathers a kind of algorithm. The model on-line are partial mainly is uses the off-line partial productions the homepage to gather the kind, again acts according to the user the current visit operation behavior, dynamic for user recommendation next step of visit operation. Has studied this model essential algorithm: The LEARNER algorithm, the individuality parsing algorithm, the individuality filters the algorithm and the CBR algorithm.5.Summary of the essay; and prospect of the future work. |
