Accumulated evidence from recent research studies has shown the effectiveness of collaborative learning situations and their role towards the acquisition of high level competencies, such as those promoted by the ESHE (European Space for Higher Education). On the other hand, service discovery, dynamic adaptation and integration may solve longstanding challenges of the TEL (Technolgy Enhanced Learning) field, such as tailorability or reuse. However, the wide use of service-based CSCL (Computer Supported Collaborative Learning) situations in real practice has been limited due to the lack of sufficient support for their complete lifecyle. CSCL is complex both in technological and pedagogical terms, and therefore state-of-the-art knowledge should be embedded in these processes in order to support the main actors implied, such as educational practitioners, designers and technology service providers. Finally, an adequate balance has to be found between effective guidance through scripting based on existing good practices and tailoring/flexibility by means of selecting adequate services, fading out of scripting, adaptation to specific roles or reaction to unexpected contextual conditions. This project builds on previous proposals by the multidisciplinary research group GSIC/EMIC and the broader community of service-based TEL systems, and aims at providing an extensible architecture based on standards and services for the support of the main actors involved in the complete lifecycle (design, enactment and evaluation) of CSCL situations. The main objective is to propose the model, prototype and use guide of the architecture, that opens a path for the adaptation, extension and integration of successful CSCL tools and services, either previously developed by GSIC/EMIC (e.g. Gridcole, Collage, Samsa, Ontoolcole/Ontoolsearch, Bersatide) or externally by other providers. The most significant partial objectives refer to:
An integrated approach for the design of scripted interweaved learning and assessment of CSCL situations, as well as support for tailorable instantiation and orchestration
A service-based platform that provides coordinated enactment and flexible adaptation of activity and data flows, in compliance with the standard IMS-LD language
A registry of significant existing/new services and tools, retrievable through an ontology-based mechanism
A methodological proposal and support for evaluation and regulation based on an adapted integration of traditional and emergent evaluation methods in a role-based framework
The new architecture will be validated progressively through controlled and authentic case studies mainly with students and teachers at the university level, although designers and service providers will also be included. The essential aspect of dissemination to the scientific (European Association of TEL), industrial (companies involved in the project) and standardization (IMS, OGF) communities will be supported by workshops and social software.
- CSCL script design process with explicit support for assessment design.
- Assessment-aware Pattern Language
- CSCL script authoring tool, called Web Collage, based on the aforementioned process and pattern language.
The latest version of Web Collage (WebInstanceCollage2 at http://pandora.tel.uva.es/wic2/) allows for design and instantiation of learning and assessment flows.
