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.

... there are 11 fields
• Analysis and Visualization of Data, • Providing Feedback for Supporting Instructors• Recommendations for Students• Predicting Student’s Performance• Student Modeling• Detecting Undesirable Student Behaviors• Grouping Students• Social Network Analysis• Developing Concept Maps• Constructing Courseware• Planning and Scheduling

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.

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

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