ABSTRACT With the spring of internet and the construction of information superhighway， learning via the net has become 也e important task in infonnation technology application，many key technology shoud be solved. Today，most net coursew缸e can not present educational contents according to personaI requirement and how to organize knolwdge-points and select resources for courseware is a issue. Organizing resources for personal courseware has two aspects，one is knowledge- points organized，which includes building courseware structure and selecting suitable knowledge-point ，and the other is selecting personal resources for this knowledge-point . When selectíng resoures for one knowledge.point ，we can take reference 企om the history records about this knowledge-point. Firstly，we built data.warehouse which subject is resource-selected . Secondly we attempted to apply the decision-tree into it and try to find the relation among the attributes of 出e resource and leamer， and this conclusion will help people selcect resources for personal co町sew缸巳 In essence，leaming coursew缸e is the traverse of knowledge-points . We studied the relation of knowledge-points and give a personal control-tactical algriothms for leaming knowledge-points . And this wiII help construct the persona1 courseware structure. As for selecting suitable knowledge-point ，we also use the the history records metioned above，and attempt to fmd the regul
