10. Learning Analytics
Learning analytics is the measurement,
collection, analysis and reporting of data
about learners and their contexts, for
purposes of understanding and
optimizing learning and the environments in
which it occurs.
Society for Learning Analytics Research (SoLAR)

12. Sensemaking
“Sensemaking is a
motivated, continuous
effort to understand
connections . . . in order
to anticipate their
trajectories and act
effectively”
Klein, Gary, Brian Moon, and Robert R. Hoffman. "Making sense of
sensemaking 1: Alternative perspectives." IEEE intelligent systems 21.4
(2006): 70-73.

19. Computer Science Program Redesign

20. Which are the hardest/more difficult courses?
What lead our students to success/failure?
How courses are related?
Are there courses that could be eliminated?
Is the work-load adequate for our students?

22. Difficulty Estimation
How difficult a course is?

23. Course Difficulty Estimation
grade > GPA
grade < GPA
0
grade = GPA
Three scenarios:
Differences between
GPA and grade
> 0< 0

24. But…
Why do these distributions look like this?
They are skewed!

•2 times during the semester
•Real classroom presentations
•Students used the system on their own

73. Effect of the System
• Looking at the public: +++
• Presentation posture: +
• Filled pauses: = +++ (For students with low scores)
• Slides: = ++

76. Can we mix LA with AI?

82. Conclusions
and a word of caution

83. LA & AI will
not replace the
Teacher
They will enable the Augmented Teacher

84. LA & AI will not limit the
options of students
They will empower Augmented Students

85. Responsible LA & AI
