2. Agenda
• Introduction
• Learning analytics for just-in-time teaching
• The classON system
– Functionality
– Implementation
– Experimental results
• Conclusions and future work
5 July 2013 LASI-Madrid 2

3. Learning Analytics
“The measurement, collection, analysis
and reporting of data about learners and
their contexts, for purposes of
understanding and optimizing learning and
the environments in which it occurs.”
SoLAR
5 July 2013 LASI-Madrid 3

4. Applications
• Predicting learner performance
• Learner modelling
• Recommendation of learning resources
• Enhance social learning environment
• Detect undesired learner behaviours
• Detect affects of the learner
• Increase learner awareness and reflection
5 July 2013 LASI-Madrid 4

5. Awareness Applications
• Awareness about student accesses to
learning resources (Mazza & Milani, 2005)
• Visualization techniques to make students
activities in the course and inform the self-
reflection (Govaerts, Verbert, Klerkx, &
Duval, 2010)
• Visualization-based awareness: GLASS
(Leony, Pardo, De la Fuente Valentín, De
Castro, & Delgado Kloos, 2012)
5 July 2013 LASI-Madrid 5
Mostly in
eLearning

6. Awareness
5 July 2013 LASI-Madrid 6
• Knowing who is around, what they
do in terms of activities and
interactions - CSCW
(Dourish & Bly, 1992)
• Lamps as distributed awareness
mechanisms in recitations
sections
(Alavi, Dillenbourg, & Kaplan, 2009)
• System that minimizes learning
progress differences in software
teaching classes
(Dong & Hwang, 2012)

7. Just-in-time teaching
Teaching and learning strategy
(Novak, Patterson, Gavrin, & Enger, 1998)
Adaptive Hypermedia & ITS
(Brusilovsky & Peylo, 2003)
Personalization,
active learning,
constructivism
5 July 2013 LASI-Madrid 7

8. Context
• Active learning activities
• Lab sessions using computers (f2f)
• Intensive tutoring support
• Engineering Degrees
• Overcrowded classes

9. The traditional approach
Students work at lab supported by the teacher’s
personalized/general explanations
• Face-to-face
• Direct interaction
• Progress monitoring?
• Questions solving?
• Particularly in overcrowded classes.

10. Problems
Collected from literature, experts and experiments
• Teacher
– … overwhelmed with questions
– … not efficiently answering them
– … not aware of students learning situation
• Students
– … monitor teacher to get their questions answered
– … not meeting the objectives of the session

11. Requirements
• Personalized monitoring
• Teacher awareness to
decide interventions
• Improve teacher efficiency
• Make students confident
that will be helped so they
make well use of the
session time
• Formative assessment
• Storage of learning traces
for summative assessment

25. Lessons learned
5 July 2013 LASI-Madrid 25

26. Conclusions
• Positive evaluation
& valuable suggestions by
– Students
– Teachers
– TEL experts discussion groups
• Q&A by students expected to
reduce help requests
– Reduce waiting time
– Reduce unresolved doubts
5 July 2013 LASI-Madrid 26
Collected results validate that classON fulfills the expected
requirements, and thus helps teachers and students to make the
most of the learning sessions with scarce resources.

27. Future Work
• New metrics
– Students comparison with the mean of the class
• Gamification
– of the activities in the assignment, Q&A
• Application to other contexts
– Project-based learning
– Extension to massive face-to-face environemnts
