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?

Educators routinely try to gather informationabout their students’ learning on the basis ofwhat students do in class. But for any questionposed in the classroom, only a few studentsrespond. Educators’ insight into what theremaining students do and do not understand isinformed only by selected students’ facialexpressions of interest, boredom, or puzzlement.To solve this problem, a number of groups areexploring the use of various technologies to―instrument‖ the classroom in an attempt to findout what students are thinking.
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 31
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
RQ#1) Are wikis created in non-poor schools used forgreater 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?

Fear, anxiety and worry about student exposure to the InternetBarbara: 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. Thats 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 dont 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 dont want that
Framework for Intervention:Cycle of Experiment and Experience Experiment Fear - Growth+ Review Plan (Experience) Institutional Capacity+
The atmosphere at our school in general is to cautiously open up to thepossibilities. So, we’re not being pushed to use technology. If we find our wayto it, and if we find obstacles that are there and we need things to change to getaccess to certain things, the administration generally will make that happen. Butthis, I think in terms of the environment, security is more important thanopenness in general and sometimes that leads us into a few obstacles….We havent gotten to the point where were making a lot of the stuff public yet.Is that possible down the road? I think with a little bit of experience, with alittle bit of, we improve the comfort level then, we can start to say, “Lets makea blog that invites other people throughout the world. Whoever wants to comevisit and check it out and be part of the conversation; lets figure how to dothat.” I dont think I should... Im not really in that place that right now. Im notsure what the response would be if I did. I think we all sort of need to build thatcomfort level piece first. But I also see that it could be pretty awesome to movein that direction.
Dear Justin,I am in the library right now and sat down to do some work onthe Wikispace to get it ready for next year. However, uponsitting down, I discovered that over the summer this websitehas been blocked by the City. I spoke to the librarian aboutappealing blocked content, but he says that they are notunblocking any sites at this time.Consequently, it does not look like we are going to be doingthis project this year. I will be trying to put togethersomething else for this unit, but at this point, I dont knowwhat we will be doing and doubt it will be appropriate foryour project because it will not be on wikispaces.com.I am very sorry; it was quite a surprise to me.
