Sample 2 - Standing Wave in a bowl
Sample 3 - Colour Loss Underwater
Sample 4 - “Bathysphere” (a submersible)
Last year….
‘Seeking’ beahviour
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
PHYS101: Energy and Waves
http://goo.gl/OgP1Mt
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…
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
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

Students report that they understand their content MUCH better after creating the LO
Student self-reported understanding of LO content before and after LO submission
• 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
★ 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
