From Raw Data to Intelligent Information in e-Learning: A Case of Study with the Khan Academy Platform




José Díaz Cappa (TSJIB)


Nowadays there are many services and e-Learning platforms which report very detailed low level data of interactions between students and e-Learning systems. However, in many cases, teachers are overwhelmed with the large amount of low-level data and they almost don’t use them as it is not easy for them to infer useful information for their courses. A major challenge is how to use computational techniques to process low-level data into useful and high-level information.


This presentation describes some ideas of learning parameters of high level learning that can be a useful information for teachers and students, as well as how to calculate them from low-level data. It also explains how to apply them in the Khan Academy platform. The many features of analytical data that provide by default the Khan Academy platform are presented, both low-level and high-level information. It also will be shown a proposal of extension of that analytical by default of the Khan Academy in combination with new high-level parameters and how to calculate them. Finally, some results of the case study conducted in 2012 in a pilot for the course 0 of physics at the University Carlos III of Madrid will be presented. In that case has been used the Khan Academy the platform, reflecting on the connection of intelligent information obtained with learning.
