Adapting informal sources of knowledge to e-Learning.Authors: Czaja Filip, Dobrzański Jarosław, Jankowski Jacek
The amount of information sources and the available data is growing dramatically fast nowadays. It is very difficult time for teachers to keep up with changes (especially in information domain) and to find new and appropriate sources of information. This problem also affects e-Learning. Contemporary e-Learning systems deliver predefined, rigid courses which usually do not take into account user specific conditions, like wishing to broaden his or her knowledge in wide range of domains at the same time. Without constant maintenance, electronic courses are also getting outdated. Moreover, all of the current solutions seem to underestimate the potential of informal learning .
According to researches, over eighty per cent of possessed knowledge is acquired from informal sources of information like wikis, blogs and digital libraries . These Web 2.0 platforms allow community collaboration, sharing knowledge and ideas. In addition, they are continuously developed to better serve users. Semantic description of available sources not only interconnects them but also allows machines to reason about their content. Consequently, artifacts can be easily accessed, browsed and harvested for further use.
Following the presented idea, we introduce Didaskon , a framework for automated composition of a learning path for a student. The selection and workflow scheduling of learning objects is based on their description, semantically annotated specification of user profiles, anticipated knowledge after course completion and technical details of the client’s platform. User profile is described with FOAFRealm Ontology , a part of FOAFRealm project. It is based on FOAF metadata that provides functionality to manage identities and share resources with friends.
Having in mind statistics about acquiring knowledge, we decided that Didaskon shall derive both from formal and informal sources of information. It should collect relevant data from wikis or blogs and process it so that it can be used in a form of learning objects, which enriches and improves the process of learning.
