This project explores the potential of MOO (Multi-user domain, Object-Oriented) as a platform for creating hypertextual online learning spaces. Specifically, it involves the creation of a large suite of MOO objects for the study and teaching of the "nonsense songs" of the British Victorian poet Edward Lear followed by classroom testing of the space with students. The final result of this project will be a working MOO-based, hypertextual literature classroom, one that provides an engaging environment for learning about a particular literary topic and that provides models for the development of similar spaces for other topics. Besides the creation of the Gromboolia environment itself, I see this project as bridging the current gap between hypertext theory and computer pedagogy, potentially broadening the scope of both fields. To hypertext theory, it will bring the idea of hypertext as a shared space and of hypertext reading as a potentially social, rather than purely solitary, activity. To the discourse on online learning environments, it will provide a MOO classroom where the subject of instruction is the teaching environment, where the structure of the knowledge to be learned or the topic to be explored shapes the space of instruction itself. In so doing, I hope to begin to reveal the unrealized potential of MOO noted by Espen Aarseth when he states that they "are not the poor relatives of more artistic textual media but contain a potential for textual complexity and diversity that is far from mastered, or even conjectured, at the present time."
