The distance learning system carries the learning activity out by modern mass-medium technology, especially the internet system. Learners break though the spatial and temporal confinement to achieve their learning by the internet. However, there are still some problems left for us to solve, e.g., the extra expenditure of the equipment and manpower, the bottleneck of the transmission of the digital information, the mastery of the digital information, the mastery of the learning interface, and so on. Owing to the diversity of the learning ability as well as learner’s knowledge background, there isn’t any learning material which is suitable for all of the learners in the internet system. Consequently, how to investigate the adaptive learning system on the internet is the studying target of this project. The existing literature provides related inquiries into the subject on the adaptive learning strategy. For instance, the adaptation strategies could be analyzed from the following four aspects: (1) the pattern of the adaptation, (2) individualization and transformation, (3) content-based or access-based system, and (4) the degree of automation. Among them, the content-based problem, also called the adjustment of the content presentation, could be further divided into two kinds: the adjustment of texts and that of multimedia. The access-based problem, also called the adaption of guiding, includes the following five strategies: (1) direct guidance, (2) adaptive sorting of links, (3) adaptive hiding of links, (4) adaptive annotation of links, and (5) the adaption of the guiding map. This project treats the above-mentioned methods as the studying target, aiming to implement the appropriate teaching material so that to achieve the maximum of learning effects. The researching steps are as follows: first, the inquiry would be examined for the relationship between the learning models and the difficulty of the teaching material, in order to sep up adaptive learning models, which take learners’ ability, the learning interest, the difficulty of the course, the duration of learning, etc. into consideration. Based on this adaptive learning system to understand internet laws, the project established an adaptive distance learning system, in which the content of the learning material is adjusted according to the learning ability and learning status. This system has been implemented and installed din Windows system, using the ASP.NET to compose the program and Flash 6.0 to edit the course. After the stage of probation in several schools, the advantage and disadvantage of this system have been further testified and analyzed according to the questionnaire. This project not only theoretically analyzes the models of the adaptive learning system but practically establishes the related adaptive learning environment. The experimental results show that the adaptive learning model suggested by this project is a feasible scheme.
