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

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

Difficulty of first edit increasing.

Sampled all new editors Feedback quality: Hand-coders: 20 Wikipedians

  • Categorized feedback
  • Rated for usefulness

New editor productivity:

  • Inferred from reverts

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

RQ2: How does prominence affect the quality and quantity of feedback?

slide-37
SLIDE 37

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

participation

  • 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
