Technology enhanced learning (TEL) aims to design, develop and test
sociotechnical innovations that will support and enhance learning
practices of both individuals and organisations. It is therefore an
application domain that generally covers technologies that support all
forms of teaching and learning activities. Since information retrieval
(in terms of searching for relevant learning resources to support
teachers or learners) is a pivotal activity in TEL, the deployment of
recommender systems has attracted increased interest. This brief
attempts to provide an introduction to recommender systems for TEL
settings, as well as to highlight their particularities compared to
recommender systems for other application domains.
