Learning analytics to ignite massive collaborative projects

Jordi Sancho Interactive Media Lab - LMI

Social work department - Faculty of Education University of BarcelonaLearning Analytics Summer Institute, June 23th Deusto, Bilbao

Problem: • Massive collaboration projects in real life but not in education (we

can’t analyse and assess them)• Student’s assignments are wasted efforts (motivation, learning

and outcomes).

Solution: To develop new analytic methodologies that scale the assessment and ignite massive collaborative learning projects.

Macro level1. Classify collaborators and contents according to their role on the process.2. Classify created documents according to content.3. Classify collaborators according to their type and role of contribution.4. Classify documents according to their quality (teacher’s criteria).

Individual levelAssign and visualise all the above items for each student and for each document.

To manage a massive collaboration project on content creation, we need to:

Accepted the challenge: PhD thesis in 2012

1. Classify collaborators and contents according to their role and importance on the process

CONCLUSIONS

Starting with the usual teaching process and “poaching” data that makes sense.

1 . WHERE IS YOUR STANDING?

Designing learning processes with the analytics in mind.

vs.

We can think big. We can rethink learning. We should ignite massive collaborating projects

(doing the same but just marginally better is not enough)

2. DRAWING NEW MAPS HAS PROBLEMS

“ Unknown Parts”

Sometimes the addition of an improved methodology produces a loss of useful knowledge. In the short time.

Are we still there?
