Why Can't I use Wikipedia?
Transcript of Why Can't I use Wikipedia?
'Shopped! What our Students need to know References http://www.fourandsix.com/photo-tampering-history/category/2011 fourandsix The reality Those words aren't always true! Yep!Well a little. China’s state-run CCTV aired a news story describing air force training exercises. A portion of the video showing an exploding jet plane was taken from the movie “Top Gun”. Military Exercise fotage Campaign Website Photo Yes! Joe Flores featured this on his website on a “Supporters” page that said only “coming soon”. It was later revealed that the person handling the website graphics had digitally added the signs to a photo that he “just grabbed from a rally somewhere on the east coast.” Yes! Under the headline “Russia refuses to recognize Libya rebels as legitimate government, clashing with West”, Saudi-owned English news website Al-Arabiya published a photo into which fighter jets were digitally inserted. The original photo (by Marco Longari for AFP/Getty) shows Libyan rebel fighters near a checkpoint on the outskirts of Ras Lanuf. http://weburbanist.com/2009/05/17/faux-photoshop-15-incredible-images-that-look-altered-but-arent/ weburbanist Newspaper Photo Action Art by Li Wei NO! The artist uses props, wires and camera angles not photo editing. Rubber Duck Nope! The rubber duck was made by artist Florentijn Hofman it measured 85’ x 65’ x 105’. Questions we can teach students to ask:
Where did the photo come from?
What is the photo's purpose?
Is this art (fantasy) or news (fact/reality)
Who was this photo intended for?
Is the editing of this photo a problem
Does it change the story? http://www.fno.org/may97/digital.html fno.org Editing of photographs is not new.
There is evidence of photographs that were edited through-out history. What is new is how easily it can be done and students need to be taught to ask questions about what they seen as well as what they read. They also need to be taught to think before they edit photos themselves. To think about:
Everyone retouches photos
There are different reasons for doing this. Why retouch a photo?
When is it okay to retouch a photo?
How much can you change? Why Evaluate? There are no guidelines for posted content online.
No one is checking the facts - well almost no one.
Instant information doesn't mean accurate information.
"As Mark Twain noted, 'A lie can travel halfway around the world while the truth is putting on its shoes'." (Ubois, 2002)
Constantly changing media needs to be checked.
Information can be hard to find. The most popular story is not always the true story.
The information on the internet is often (alway?) bias. http://ed.uiuc.edu/wp/netfiles.uiuc.edu/alhiggin/www/credibilityindex.htm An Educator's Guide to Credibility and Web Evaluation The problem with Wikis http://piratepad.net/H4niDenqMZ http://piratepad.net/WMPfGepm2p http://piratepad.net/LN8td7P6UQ http://school.discoveryeducation.com/schrockguide/eval.html Kathy Schrock Guide to Educators http://bandhmo.org/ Authority Accuracy PUrpose Currency SCOPE Who Wrote it?
Why did they write it?
When was it written?
Is the information bias?
Is the information complete? About Wikipedia: http://lib.nmsu.edu/instruction/evalcrit.html Evaluation Criteria What our students need to know:
Wikipedia is not evil - it is a great place
to start when looking for information on a new
or unfamilar topic.
It is the start not the end of the research.
Look at articles and websites referenced on wiki for
more information and ideas of places to look.
As with any source confirm your information. https://docs.google.com/present/view?id=dfvwdtqp_2cmt22hfv A lesson from Google https://docs.google.com/View?id=dfvwdtqp_1c8x6bmd8&pli=1 A lesson from Google http://www.library.ualberta.ca/instruction/science/evalweb.pdf Evaluating Web Resources Checklist Common Sense! What Wikipedia has to say about wikipedia Wikipedia is written collaboratively by largely anonymous Internet volunteers who write without pay. Anyone with Internet access can write and make changes to Wikipedia articles (except in certain cases where editing is restricted to prevent disruption or vandalism). Users can contribute anonymously, under a pseudonym, or with their real identity, if they choose. 1 Wikipedia is written largely by amateurs. Those with expert credentials are given no additional weight. Some experts contend that expert credentials are given less weight than contributions by amateurs. Wikipedia is also not subject to any peer review for scientific or medical or engineering articles. 2 Users should be aware that not all articles are of encyclopedic quality from the start. Indeed, many articles start out by giving one—perhaps not particularly evenhanded—view of the subject, and it is after a long process of discussion, debate, and argument that they gradually take on a consensus form. 3 (on 12 August 2011) An article in The New York Times cites a Wikimedia Foundation study which found that fewer than 13% of contributors to Wikipedia are women. 4 Another tool for Students http://21cif.com/tools/evaluate/ Try it on this site: http://zapatopi.net/treeoctopus/ Reliability Rules Ask students: How can you find out if something is true? We do not expect you to trust us It is in the nature of an ever-changing work like Wikipedia that, while some articles are of the highest quality of scholarship, others are admittedly complete rubbish. We are fully aware of this. 5 Who is able to give the best information on a topic? Who do you trust? You hear a rumor your best friend likes Justin Bieber. You have a horrible cough that won't stop. You wonder how hot Venus is. Is how current a information is always important? Who am I? Who are you? What are we going to do today? Fact or opinion? Students often believe that what they read, what they see on TV, or what they find on the internet are all facts. It’s critical for them to know that difference between a fact and an opinion. The internet in particular is a breeding ground for opinions. Part of being a good evaluator is being able to sniff out the opinions from the facts. http://pbskids.org/arthur/games/factsopinions/ http://evaluatingwebsitesforteachers.wikispaces.com Activity: The Weather in Canada http://answers.yahoo.com/question/index?qid=20071003044107AAiFKUM http://www.climate.weatheroffice.gc.ca/Welcome_e.html http://en.wikipedia.org/wiki/Main_Page
