AgendaI. Explore Nested Structure of Web 2.0
Data
II. Schema of Web 2.0 Research Methods
III. Prospectus for Researching Classroom Wikis
I. Efficacy: How do we make them good?
II. Equity: Do only certain kids get the good ones?
IV. Dip in to the data2
What are wikis and why should we study them?
• DEFINITION: Wikis are Web sites where any one can edit any page at any time
• GROWING IMPORT: Use of Web 2.0 tools and networks (blogs, wikis, social networks, discussion forums) is growing exponentially in education, and transforming our society
• STUDENT-CENTERED: A democratic, citizen-centered ideology is “baked into” wiki architecture making them promising platforms for teaching 21st century skills
• ***NESTED, RETROSPECTIVE CORPUS***: Wikis preserve their entire history of activity in a nested data structure that allows research of infinitely variable granularity (like Google Earth) 3

Classroom Wiki Research Questions
• How do we make them good?– What best practices, attitudes and resources
produce wiki learning environments that promote and nurture 21st century skills?
• Do only certain kids get the good ones?– What is the distribution of high quality wikis across
schools serving different student populations?

Path Diagram of Wiki Research
Excellence:How does wiki quality vary by
teacher attitudes, practices, and resources?
Are good wikis born or made?
Equity:How does wiki quality vary by
school SES variables like %FRPL, Per Pupil Expenditure, Title I status, or measures of racial
composition
