Problem statement New functionality in LMS is usually done
bycreating and installing a module The installation is site-wide:
affects everyclass in the LMS There is administrative overhead The
module must be as stable as possible How can we enable the
deployment ofvisualizations in LMS without installingmodules in the
server?TaPTA Workshop 20127 8. Proposed solution Two components: At
the server: Learning analytics service In charge of generating a
dynamic visualization Web browser extension Installed on the client
side TaPTA Workshop 2012 8 9. Proposed solution Learning analytics
service: Generating visualization to embed in LMS Visualization can
be static or interactive The visualization can be
personalized:Different roles (learner, instructor)Depending on
context (location, time) TaPTA Workshop 20129 10. Proposed solution
Web browser extension: Applying content script on two course URLs
Home page of the course Embed a widget with the personal
visualization Page with list of participants Embed a visualization
next to each portrait Only applicable if the user is an instructor

components TaPTA Workshop 2012 11 12. Proposed solution Our
implementationTaPTA Workshop 2012 12 13. Discussion Some issues to
be discussed: Unification of user identities Fragmentation of
client software versions Dependency on the LMS layout Security of
the communication between components Future work: Test the
components in a real scenario Generalize the browser extension
