Web based self-directed learning environment using learner´s annotation

In this paper, we introduce a Web based self-directed learning environment using a student\´s Web-annotation and describe the evaluation of our system. SDL (self-directed-learning) is one of the teaching methods that supports the autonomous learning of the learner. However, it is difficult for the learners to choose a web page suitable for their learning purpose as the learning resource in the web based SDL. We developed a prototype system that is called "Retracer". Our environment recommends the web pages and information that it is useful for the learner using the learner\´s annotation. This method analyzes the feature of a Web page, and extracts the learning resource suitable for a student need using a Web-annotation. Finally, we got the good result in a trial use.
