Abstract :
Acquisition and preprocessing of data is a
fundamental
step in the process of searching for educational data and
also represents the initial stage of the adaptation cycle.
The nature of the monitoring data is a decisive factor for
later stages of the cycle and for further analysis. Most
adaptive e
ducation systems share a strong dependency of
this early stage of the process. However, the accuracy of
the data itself and the way they are being effectively
monitored data may differ.
