Learning analytics is the interpretation of learner-specific data to improve the individual learning process. It involves collecting traces left by learners and using them to enhance learning. While the potential is difficult to assess given increasing data volumes may reveal new insights, learning analytics aims to discover information, social connections, predict learning, and provide recommendations and feedback to support learners and instructors. Key applications include analyzing performance, modeling students, detecting behaviors, grouping students, and developing courseware.

3. Educational Data Mining
Educationa data mining (EDM) is a field
that exploits statistical, machine-learning,
and data-mining (DM) algorithms over
the different types of educational data. Its
main objective is to analyze these types
of data in order to resolve educational
research issues.

5. Learning Analytics
Learning Analytics is the use of intelligent
data, learner-produced data, and analysis
models to discover information and social
connections, and to predict and advise on
learning.

6. Learning Analytics
Learning Analytics is about collecting
traces that learners leave behind and
using those traces to improve learning.

21. Learning Analytics ist die Interpretation
von lernerspezifischen Daten um den
individuellen Lernprozess gezielt zu
verbessern.

22. Potenzial ist heute noch schwer
abschätzbar, da mit zunehmender
Datenmenge gänzlich neue Sichtweisen
gewonnen werden können.
