The World Wide Web contains rich collections of digital materials that can be used in education and learning settings. The collaborative authoring prototype of Walden's Paths targets two groups of users: educators and learners. From the perspective of educators, the authoring tool allows educators to collaboratively build a Walden's Path by filtering and organizing web pages into an ordered linear structure for the common information needs, which can be extended, tailored and modified into a derivative path from its parent version to meet dynamic and evolving educational requirements. From the students' perspective, Walden's Paths provide a shared knowledge space that facilitates collaborative learning. Specifically, collaborative learners can annotate locally and globally on pages and share among group members, where each annotation fosters the initiation of a thread of discussion. Therefore, knowledge transfer can be achieved in the process of social interaction associated with shared annotations.
