Enabling lifelong learner modelling through Blockchain technology

Venue: Birkbeck Main Building

In this seminar will discuss the possibility of using blockchain technology to integrate formal and informal learning experiences into a common lifelong learner model.

First, we will review the area of user model interoperability and present our theoretical framework for designing personalized learning paths for lifelong learners. The framework supports contemporary pedagogical approaches that can promote the idea of a cumulative learning continuum, from pedagogy through andragogy to heutagogy, where lifelong learners progress in maturity and autonomy. The framework design builds on existing conceptual and process models for pedagogy-driven design of learning ecosystems.

Second, we will examine the emerging role of distributed ledger technology in the context of learner modelling. We propose a new methodology for sharing learner information that can guarantee the quality (provenance and accuracy) of the exchanged learner data while minimising the need of trust between the parties that share information. Our approach envisages a distributed ledger storing learning experiences in the form of Experience API statements, which can be used to build individual learner models.


Konstantinos Karoudis has a Diploma in Electrical and Computer Engineering from the Democritus University of Thrace, Greece, and an International MSc in Information Technology from the University of Stuttgart, Germany. He has worked at the IBM Germany Research and Development Lab and held research posts at the University of Karlsruhe, and at Birkbeck, University of London, where he participated in the European Commission funded project ‘LIBE: Supporting Lifelong Learning with Enquiry-Based Education’, by developing an engine that personalises individual learners’ experience. Konstantinos is currently working towards a PhD at Birkbeck, University of London in the area of Technology-Enhanced Learning.
