Issues in discussion

  • Generalizability
    • Humble theory
  • Data literacy of teachers, admins…
  • The need for creativity in LA
    • The need for creativity in assessment
  • Learning analytics: singular or plural?
  • Research methods, analysis techniques

EDM (paper 1 & 2)

Educational Data Mining is concerned with developing, researching, and applying computerized methods to detect patterns in large collections of educational data – patterns that would otherwise be hard or impossible to analyze due to the enormous volume of data they exist within.

Educational Data Mining is an emerging discipline, concerned with developing methods for exploring the unique types of data that come from educational settings, and using those methods to better understand students, and the settings which they learn in.

(vs. LA?)

Typical steps in an EDM project (paper 1)

  • data acquisition
  • data preprocessing
  • data mining
  • validation of results

(vs. LA?)

Methods in EDM (paper 1)

  • Prediction
  • Clustering
  • Relationship mining
  • Distillation of data for human judgment
  • Discovery with models

Application Areas (paper 3)

  • User knowledge modeling
  • User behavior modeling
  • User experience modeling
  • User profiling
  • Domain modeling
