8. Big Data Analysis based on THEOL
Current research data based on
 Student-, teacher- and institutional level information from MIS;
 Teaching and learning activities from e-learning platform;
 Rating instruction/evaluation information from e-assessment system;
 More than 10 years longitudinal data.

10. Type of analytics Level or object of analysis We are doing now
Learning
analytics
Personal level: analytics on personal
performance in relation to learning
goals, learning resources, and study habits of
other classmates.
Course-level: social networks, conceptual
development, discourse analysis, “intelligent
curriculum”
Designing a new Learning
analytics system
Departmental: predictive modeling,
patterns of success/failure
Designing E-portfolios
Academic
Analytics
Institutional: learner profiles, performance
of academics, knowledge flow, resource
allocation Multiple comparisons based
on THEOL series softwareRegional (state/provincial): comparisons
between systems, Quality and standards
