Relevant Behavioral Abstractions (Features) Education needs explainable AI Computational Education Models Research Pierre Dillenbourg, EPFL

Relevant Behavioral Abstractions (Features) gaze(a)=ƒ(gaze(b))

Gaze Recurrence

Relevant Behavioral Abstractions gaze(listener)=ƒ(gaze(speaker)) Feature: Gaze recurrence Context: Collaborative learning

Relevant Behavioral Abstractions gaze (learner) = ƒ (reference (teacher)) Feature: Withmeness Context: Lecturing

Do finger-based or gaze-based deictics enhance learning ? Sarah d’Angelo, Kshitij Sharma, Darren Gergle, Pierre Dillenbourg (2016)

Relevant Behavioral Abstractions gaze (learner) = ƒ (gaze (teacher)) Feature: ‘Withmeness’ Context: Lecturing

K t B t Modeling in the wild ? Raca, Tormey & Dillenbourg

Relevant Behavioral Abstractions gaze (learner) = ƒ (location (teacher)) Feature: Head rotations Context: Lecturing

activity (teacher) = ƒ (gaze (teacher)) L. Prieto, K. Sharma, L. Kidzinsky, P. Dillenbourg

Education brings nice challenges (1) Explainability Computational Education Models Research Pierre Dillenbourg, EPFL

Education brings nice challenges (2) Cold Start Integrate expert’s knowledge Use simulation with synthetic students

Education brings nice challenges (3) Exploration Exploitation Tradeoff Learner 1 A B Learner 2 Learner 3 A Learner 4 A Learner 5 Learner 6 A Learner 7 A Learner 8 ? Learner 9

Education Context Exploration/ Explainable AI Cold Start Exploitation Trade-OFF Cohorte Simulations

Multi-Armed Bandit (MAB) for Exploration-Exploitation ➢ Selecting learning activities ➢ LFA model ➢ Tested with simulated students ➢ Will present and discuss this work at ECTEL in Septembre 59 Louis Faucon, Pierre Dillenbourg, EPFL
