Expert Guided Crowdsourced Learning Content - STEM 2014

  5. 5. ‘Seeking’ behaviour
  6. 6. Challenge: Can we enhance the pre-reading activity to engage more students more deeply with the material? • Requirements: • Outputs: distributed over the whole term • Load: at least 2h of student time • Assessment: Submitted online, marked using a rubric • TA Load: No increased marking load ! Pilot study in 3 sections of PHYS101 Jan-Apr 2014

  12. 12. Sample Learning Objects Ted-Ed: A video tutorial and a series of questions linked to time-stamps Screencast: A slideshow with annotations and voice narrations Prezi: A visual slideshow format that can be used to break down problems and many more…
  13. 13. Implementation - Logistics • Cohort split into 4 groups, 2 cycles per semester • Required to submit two (2) learning objects over the course of the term, each worth 2.5% of course grade. • In addition to the two assigned weeks, students can submit additional LOs • The two highest scoring learning objects will be used to determine themark. • LO topic must be on pre-readings for the next week
  14. 14. Implementation - Submission & Survey • Students submitted attachments or links to LOs online through the Blackboard LMS • Upon submission, students complete a short survey: • How did you come up with your LO topic? • Time Spent • How much did you understand the topic before/ after LO creation • Other feedback
  15. 15. physics.lo.open.ubc.ca Learning Objects are showcased here:
  16. 16. Sample 1 - Were Astronauts really on the moon?
  17. 17. Sample 2 - Standing Wave in a bowl
  18. 18. Sample 2 - Standing Wave in a bowl
  19. 19. Sample 3 - Colour Loss Underwater
  20. 20. Sample 4 - “Bathysphere” (a submersible)

  29. 29. • Major Challenge: How to determine whether students that did an LO on a specific topic are actually primed to understand content better? • [Reminder] Requirements of new activity: ✓ Output: distributed over the whole term ✓ Load: at least 2h of student time ✓ Assessment: Submitted online, marked with rubric ★ TA load: No increased marking load on existing TAs Future Directions
  30. 30. ★ TA load: No increased marking load on existing TAs Option 2: Crowd-source LO assessment by assigning LOs to be marked by students Only two choices: Option 1: Redistribute resources to reallocate TA hours to marking and curating
