PeerWise bridging the gap between online learning and social media
Department of Computer Science The University of Auckland New Zealand
• Web-based MCQ repository built by students
• Students: – develop new questions with
associated explanations – answer existing questions and
rate them for quality and difficulty – take part in discussions – collaborate in a community
space
About PeerWise
Student familiarity with
Web 2.0 The energy and
creativity of a large class
Student generated questions

• To date
– 77 institutions
– 557 courses
– 33757 students have contributed
– 94207 questions have been written
– 2308854 answers have been submitted
About PeerWise
Implemented in 2 successive introductory Physics courses (1A & 1B)
P1A: workshop session in Week 5
Student groups worked Through structured Example & devised own Qs
20
Implementation
An assessment was set for the end of Week 6:
Minimum requirements:
• Write one question • Answer 5 • Comment on & rate 3
Contributed ~3% to course assessment 21
Implementation
22
We were deliberately hands off.
• No moderation • No corrections • No interventions at all
But we did observe…..
23
Implementation
P1A in-course assessment (N=200)
350 user-contributed questions in total
~3500 answers ~2000 comments

Generally, students did:
• Participate beyond minimum requirements
• Genuinely surprise us with the quality of submissions, creating problems not exercises
• Engage in community learning, correcting errors
• Provide positive feedback on using PeerWise 30
Findings
Generally, students did not:
• Contribute trivial / irrelevant questions
• Submit questions with ‘bad physics’
• Let mistakes or errors persist
• Use it much beyond the assessment periods
31
Findings
Does degree of PeerWise activity correlate with end of course performance?
Yes, for the majority of students
32
Findings
Defining activity:
• Combined measure of number of questions, answers, comments and days of activity (Q,A,C & D)
• Divide student score on each of 4 individual measures into deciles and award score 0 10
33
Findings
Defining activity:
• CM scores from 0 40
• Median split of cohort on the basis of CM scores into ‘HPA’ and ‘LPA’.

Summary
• Pilot use of PeerWise in two successive intro Physics courses
• Clear evidence of student engagement, with high quality submissions and discussions
• Use of system correlated with course outcome, and not just for the best students
