WEAVING THE WEB

We suggest an ontology-based framework for Web-based learning to be applied with Google Wave. The suggested framework – a model and a skeletal methodology, offers a new approach to Technology-Enhanced Learning, integrating Web 2.0 concepts and tools with advanced pedagogical models, using as platform the innovative Google Wave technology (hereby abbreviated GWave).
Our proposed framework is based on: a) an ontology of pedagogical concepts, b) Web 2.0 technologies, c) Web 2.0 notions of knowledge sharing, collaboration and contribution. The key concepts in the ontology are: a) pedagogical models, b) learning goals, c) collaborative learning scripts. The key steps in activating GWave-based collaborative learning environment are: 1) determining the learning goal, 2) mapping the learning goal to the appropriate pedagogical model, 3) enacting a collaborative pedagogical script embedded in the GWave environment (i.e., for supporting collaborative learning), and finally 4) applying a series of rules that help assess the collaborative learning script in accordance with the learning goals.
The suggested framework allows the selective application of a) Web- and Web 2.0 tools in accordance with the spectrum of technologies and methods available through GWave, b) the social construct, c) the pedagogical scenario (e.g., role-play, group inquiry, problem solving, competition, reaching to agreement, etc.) d) its enacting and e) evaluation.
GWave a serves as an umbrella application that facilitates and hosts not only a spectrum of Web 2.0 tools but also common other knowledge sharing features (e.g., media sharing). Web 2.00 tools (e.g., Blog, Wiki, Knowledge sharing systems, Mashup) allow the realization of a spectrum of learning- and teaching processes such as: planning (e.g., Mashup), editing (e.g., wiki, blog) and design (e.g., Learning object).
In order to allow a complete learning script lifecycle a theory is required to guide the design of a model and a methodology to instruct its realization. In this paper we suggest a) an upper-level ontology of pedagogical scenarios, b) a model and a skeletal methodology for the management of a learning scenario (i.e., that is integrated in the GWave architecture), and c) instantiations of this model demonstrated by two example scenarios.
There is much promise in the framework suggested here. First is overcoming shortages of Web 2.0 tools in the context of supporting learning script lifecycle. Second is enhancing the activity range of classic LMS beyond the (limited) collaboration allowed by these systems towards networking and collaboration, a user-centered approach to learning and a cost-free and widely available environment.
Two scripts are being illustrated through a single run-time embedded plug-in in GWave environment. The suggested framework will be tested for its feasibility and usefulness wi
