“The measurement, collection, analysis and reporting of data about learners and their contexts,

• Use data for formative assessments and than:
• Tailor instruction to students’ needs
25 yrs of research, 50 000 studies, 200M students
Visible Learning for Teachers: Maximizing Impact on Learning, J. Hattie, 2011
Lectures were once useful, but now, when all can read and books are numerous, lectures are unnecessary.
If your attention fails and you miss part of a lecture, you are lost; you cannot go back as you do upon a book.
James Boswell - Life of Johnson (1791)

PROBLEMS
•Maybe it is too much data, can we manage it?
•Once collected, what to do with all this numbers?

MACHINE LEARNING
Machine learning, a branch of artificial intelligence, is about the construction and study of systems
that can learn from data.
Field of study that gives computers the ability to learn without being explicitly programmed
BIG DATA O BIG BROTHER?
• TV advertisements and counterprogramming
• Internet advertising
• Credit card and consumer credit authorizations
• Fidelity cards (Travel Club, FNAC, much more ...)
• Buying recommendations, cross selling and upselling
• Churn rates
... but not in education!

• Tests with variable difficulty (self-adjustable)
• Full text search of all the content, audio included
• Log of everything

FIRST BENEFITS
• Adapt the difficulty of the test questions based on student’s behavior (“student model”).
• Feedback to the content/class authors.
• Flipped classroom.
Quizzes with personalized difficulty
Implicit feedback on video viewing
Implicit feedback on video viewing
FLIPPED CLASSROOM
• Learn the theory at home, exercises at school
• More time to resolve unclear points and practical examples.
• Peer instruction.
MORE IDEAS
• Cross-usage of the data of different students
• Personalized sequence of (optional) videos
• Personalized annotations of the material
• Group creation/assignment
• Early outlier detection
