Wiki Opportunities for Students to Develop
            21st Century Skills
• Expert thinking:
   – Do students use academic content knowledge in wiki activities?
   – Do students reflect on the process/product?
• Collaboration:
   – Do students concatenate text on pages?
   – Do they substantively edit each others work and co-create
     pages?
• New Media Literacy:              Wiki Quality Instrument
   – Do students use formatting?        25 Questions
   – Do they hyperlink?
   – Do they embed multimedia?

Data
Educators routinely try to gather information
about their students’ learning on the basis of
what students do in class. But for any question
posed in the classroom, only a few students
respond. Educators’ insight into what the
remaining students do and do not understand is
informed only by selected students’ facial
expressions of interest, boredom, or puzzlement.
To solve this problem, a number of groups are
exploring the use of various technologies to
―instrument‖ the classroom in an attempt to find
out what students are thinking.
Back Deck
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?
                                                     25
Open Education Resources
• Twin Hopes for OER
  – (Excellence) Teachers will use free, online
    tools and resources to create student-
    centered learning environments that prepare
    students for 21st century life
  – (Equity) Since these materials are free, poor
    students will disproportionately benefit.

How can we operationalize usage?
Usage as persistence
• Wiki lifetime: number of days of activity of
  a wiki community
  – Birth: Creation of wiki subdomain (e.g.
    ReichWorldHistory.pbworks.com)
  – Death: Final wiki edit
     • After a 90 day observational period



                                                 30
How can we operationalize usage?
Usage as opportunities to develop 21st
  century skills
• Participation
• Expert Thinking
• Complex Communication
• New Media Literacy

What are our research questions?
RQ #1) Persistence: Are wikis created in
 schools serving affluent students used for
 greater lengths of time than wikis created
 in poor schools?
RQ#2) Participation: Do wikis created in
 schools serving affluent students provide
 more opportunities for students to develop
 21st century skills
                                          33
Which wikis are in my sample?
• Dataset
  – All179,853 publicly-viewable education-related wikis
    started on the PBworks platform between June 2005
    and August of 2008.
  – Does not include ―private‖ wikis (~70,000)
• Sample
  – Randomly sampled 1,799 wikis (1%)
  – Coded to identify 259 U.S. based, K-12 wikis from
    specific public schools
     • Detailed usage statistics provided by PBworks.com
     • Demographic school level data from the Common Core of Data
       (National Center for Education Statistics, 2007-2008)        34
What are our data analytic
       strategies?
RQ#1) Are wikis created in non-poor schools used for
greater lengths of time than wikis created in poor schools?

 • Estimate survival functions of wiki groups by Title I status
   using Kaplan-Meier estimation; use Wilcoxon’s test to
   test for differences



     where
 S(ti) is the estimated survival probability in any of t time
     periods, which are delineated by instances of wiki death
 ni is the number of wikis still active at the beginning of time
     period ti;
 di is the number of wikis that become inert during time
     period ti.
RQ#2) Do wikis created in non-poor schools exhibit
   more evidence of collaboration and student
 involvement than wikis created in poor schools?
     Estimate wiki quality trajectories using the multilevel
     model for change.

Discussion
• Participatory behavior is rare across all wikis, but
  both student involvement and collaboration can
  be found in wikis from both poor and non-poor
  schools
• Wikis from non-poor schools persist longer than
  wikis from poor schools.
• The Open Education Resources strategy of
  promoting free online tools and resources may,
  counter-intuitively, expand the second digital
  divide—in the absence of targeted interventions.
                                                    48
How can we begin to explain
       these patterns?
• What might explain our empirical findings?
  – What obstacles do poor schools have in using wikis?


• Qualitative Research
  – Interviews with 50+ wiki-using teachers, many drawn
    at random from our PBworks samples.
  – 35+ focus groups with students
  – Classroom observations in 12 schools in
    MA, CT, ME, NH, CA, GA, VA
What obstacles exist for wiki use in
           poor schools?

• Differences in resources?
• Differences in school culture?

  you want but I never want us on the frontpage with some

  interesting. That's why he told our technology committee.
  Our main goal is to not make the frontpage with the bad

The atmosphere at our school in general is to cautiously open up to the
possibilities. So, we’re not being pushed to use technology. If we find our way
to it, and if we find obstacles that are there and we need things to change to get
access to certain things, the administration generally will make that happen. But
this, I think in terms of the environment, security is more important than
openness in general and sometimes that leads us into a few obstacles….

We haven't gotten to the point where we're making a lot of the stuff public yet.
Is that possible down the road? I think with a little bit of experience, with a
little bit of, we improve the comfort level then, we can start to say, “Let's make
a blog that invites other people throughout the world. Whoever wants to come
visit and check it out and be part of the conversation; let's figure how to do
that.” I don't think I should... I'm not really in that place that right now. I'm not
sure what the response would be if I did. I think we all sort of need to build that
comfort level piece first. But I also see that it could be pretty awesome to move
in that direction.
Dear Justin,

I am in the library right now and sat down to do some work on
the Wikispace to get it ready for next year. However, upon
sitting down, I discovered that over the summer this website
has been blocked by the City. I spoke to the librarian about
appealing blocked content, but he says that they are not
unblocking any sites at this time.

Consequently, it does not look like we are going to be doing
this project this year. I will be trying to put together
something else for this unit, but at this point, I don't know
what we will be doing and doubt it will be appropriate for
your project because it will not be on wikispaces.com.

I am very sorry; it was quite a surprise to me.

  • 23. Educators routinely try to gather information about their students’ learning on the basis of what students do in class. But for any question posed in the classroom, only a few students respond. Educators’ insight into what the remaining students do and do not understand is informed only by selected students’ facial expressions of interest, boredom, or puzzlement. To solve this problem, a number of groups are exploring the use of various technologies to ―instrument‖ the classroom in an attempt to find out what students are thinking.
  • 25. 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? 25
  • 26. Open Education Resources • Twin Hopes for OER – (Excellence) Teachers will use free, online tools and resources to create student- centered learning environments that prepare students for 21st century life – (Equity) Since these materials are free, poor students will disproportionately benefit.

  • 48. Discussion • Participatory behavior is rare across all wikis, but both student involvement and collaboration can be found in wikis from both poor and non-poor schools • Wikis from non-poor schools persist longer than wikis from poor schools. • The Open Education Resources strategy of promoting free online tools and resources may, counter-intuitively, expand the second digital divide—in the absence of targeted interventions. 48
  • 49. How can we begin to explain these patterns? • What might explain our empirical findings? – What obstacles do poor schools have in using wikis? • Qualitative Research – Interviews with 50+ wiki-using teachers, many drawn at random from our PBworks samples. – 35+ focus groups with students – Classroom observations in 12 schools in MA, CT, ME, NH, CA, GA, VA
  • 50. What obstacles exist for wiki use in poor schools? • Differences in resources? • Differences in school culture?

  • 52. Fear, anxiety and worry about student exposure to the Internet Barbara: There was - the superintendent said, "Do want you want but I never want us on the frontpage with some bad headline" [chuckle]. I thought those are kind of interesting. That's why he told our technology committee. Our main goal is to not make the frontpage with the bad headline attached. Jim: And as far as I know but I don't want to be the person to be in the newspaper for... Look at what this kid was doing on the internet in a school. I don't want that

  • 54. The atmosphere at our school in general is to cautiously open up to the possibilities. So, we’re not being pushed to use technology. If we find our way to it, and if we find obstacles that are there and we need things to change to get access to certain things, the administration generally will make that happen. But this, I think in terms of the environment, security is more important than openness in general and sometimes that leads us into a few obstacles…. We haven't gotten to the point where we're making a lot of the stuff public yet. Is that possible down the road? I think with a little bit of experience, with a little bit of, we improve the comfort level then, we can start to say, “Let's make a blog that invites other people throughout the world. Whoever wants to come visit and check it out and be part of the conversation; let's figure how to do that.” I don't think I should... I'm not really in that place that right now. I'm not sure what the response would be if I did. I think we all sort of need to build that comfort level piece first. But I also see that it could be pretty awesome to move in that direction.
  • 55. Dear Justin, I am in the library right now and sat down to do some work on the Wikispace to get it ready for next year. However, upon sitting down, I discovered that over the summer this website has been blocked by the City. I spoke to the librarian about appealing blocked content, but he says that they are not unblocking any sites at this time. Consequently, it does not look like we are going to be doing this project this year. I will be trying to put together something else for this unit, but at this point, I don't know what we will be doing and doubt it will be appropriate for your project because it will not be on wikispaces.com. I am very sorry; it was quite a surprise to me.
