5. Constructive Controversy
(Deutsch 1949; Lewin, 1948; Johnson & Johnson, 1998; 2009)
✴ Argue incompatible views within a cooperative context

✴ Seek agreement integrating the best evidence and
reasoning from both positions

Current Research Questions:
1) Why does asynchronous CMC affect constructive controversy?
2) Can initial belongingness ameliorate the negative effects of
asynchronous CMC?

Belongingness

!
→ Developing belongingness between students is an
important precondition for promoting cooperation and
motivation
!
→ Instructors may be able to monitor and enhance students’
cooperative perceptions and epistemic regulation
4. Motivation
!
5. Achievement
→ Varying synchronicity to match the different task demands
of constructive controversy may maximize the affordances
and minimize the constraints of each

37. Bonus!
How to leverage belongingness at scale?
!
Mere belonging - “a minimal social connection”
(Walton et al., 2011)
Perception that course will
have collaborative social
interactions
Shared birthday with peer
role model
Shared esoteric preferences
(e.g., music) with a peer
learner
Motivation &
Persistence
