Legitimate Peripheral Participation

Lave & Wenger

Situated learning: Legitimate peripheral participation. Cambridge University Press, 1991.

How do newcomers enter communities of practice? "Community of Practice"?

slide-10
SLIDE 10

Legitimate Peripheral Participation

  • A group of people

with a specific skill.

  • Newcomers seek to

gain skills and enter community

slide-11

Legitimate Peripheral Participation

Newcomer Community of people doing a thing

Legitimate Peripheral Participation

Newcomer Community of people doing a thing

Newcomer evaluates community. Community evaluates newcomer.

Becoming Wikipedian - Bryant, Forte & Bruckman, GROUP'05

At the periphery of Wikipedia, novice users contribute by reading articles out of interest, noting mistakes or

  • missions, and correcting them.
slide-17
SLIDE 17

Wikipedia's changed since 2005

Newcomers' first edits

  • More complex
  • Higher risk of failure
slide-18
SLIDE 18

Difficulty of first edit increasing.

Overview of Results

Quantity Quality Editors' concerns Readers' concerns

RQ1: How does the request affect the quantity and quality of feedback?

slide-34
SLIDE 34

Overview of Results

  • 1. "Did you find what you were looking for?"

○ Boost contribution rate by 45% over asking for rating ○ No loss in usefulness

Overview of Results

RQ3: How does the presence of the feedback form effect new editor conversion?

  • could cannibalize primary contributions (edits)
  • could be a stepping stone
slide-38
SLIDE 38

Overview of Results

  • 3. Invitation to edit after feedback submission

○ Boost new editor conversions by 151% ○ 20% drop in productivity*

Conclusions

  • No tradeoff between quantity and quality of

participation

Conclusions

  • No tradeoff between quantity and quality of

participation

Rick Wash and Cliff Lampe. “The Power of the Ask in Social Media” Proceedings of the ACM Conference on Computer Supported Cooperative Work (CSCW). Seattle, WA. February 2012.

  • Inviting readers to covert

○ Increases the rate of new editors ○ But at a lower success rate ○ Anti-vandalism tools negated cost to community

  • Inviting readers to covert

○ Increases the rate of new editors ○ But at a lower success rate ○ Anti-vandalism tools negated cost to community

Now everyone look at Dario

WE WANT YOU... FOR SCIENCE

  • Machine learning --> feedback moderation
  • Predictive models --> new editors
  • Cultural and language barriers to

participation
