Software components for distance and just-in-time (JIT) learning are an increasingly common method of encouraging reuse and facilitating the development process[58], but no analogous efforts have been made so far for designing hypertext components that can be reused in educational offerings.1 We argue that such structures will be of tangible benefit to the online learning community, serving to offload a substantial burden from programmers and designers of software, as well as allowing educators without any programming experience to customize available online resources. We present our motivation for hypertext structure components (HTSC) and then propose a set of pedagogical structures and their building blocks that reflect the categories of lecture, laboratory, creative project, playground, and game[38].
