- 5. Context • Visualizations are a common method to provoke interventions Visualizations generated with LearnGLASS TaPTA Workshop 2012 5
- 6. Context • The LMS is one the best channels of communication to deliver visualizations TaPTA Workshop 2012 6
- 7. Problem statement • New functionality in LMS is usually done by creating and installing a module • The installation is site-wide: affects every class in the LMS • There is administrative overhead • The module must be as stable as possible • How can we enable the deployment of visualizations in LMS without installing modules in the server? TaPTA Workshop 2012 7
- 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 2012 9
- 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 TaPTA Workshop 2012 10
- 11. Proposed solution • Communication between components TaPTA Workshop 2012 11
- 12. Proposed solution • Our implementation TaPTA 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 TaPTA Workshop 2012 13
