Empower artificial intelligence webinar week a personalized early warning system for supporting learners the uoc case by david baneres

  1. 1. A personalized early warning system for supporting learners: the UOC case David Bañeres (dbaneres@uoc.edu) Universitat Oberta de Catalunya
  2. 2. UOC Virtual Campus StaffFaculty Students
  3. 3. UOC Virtual Campus StaffFaculty Students - Provide support - Manage programmes - Manage system - Solve questions - Provide support - Prepare activities - Assess activities - Generate resources - …- …
  4. 4. • Some repetitive tasks can be (semi)-automated Potential enhancement: • We can provide a real 24x7 support to students • We can provide a better personalized support
  5. 5. LIS: Learning Intelligent System • Project supported by the eLearn Center through the New Goals call • 3 years project • A research group composed of 4 members
  6. 6. Principal Aim To develop an adaptive system to be globally applicable at UOC campus to help students to succeed in their learning process.

  35. 35. Consecutive non-submitted One activity non-submitted Submit activity Informational feedback Nudgeting system
  36. 36. Not accessed on activity Not yet submitted activity Already submitted the activity Remainder Nudgeting system
  37. 37. Lessons learned ● Predictive model needs further analysis to be applied on real setting ● Infrastructure solves particular UOC setting ● Is the EWS/nudgeting system really useful?
