Wikipedia:FAQ/Schools - Wikipedia, the free encyclopedia - 0 views

  • Students should never use information in Wikipedia (or any other online encyclopedia) for formal purposes (such as school essays) until they have verified and evaluated the information based on external sources. For this reason, Wikipedia, like any encyclopedia, is a great starting place for research but not always a great ending place.
  • It is possible for a given Wikipedia article to be biased, outdated, or factually incorrect. This is true of any resource. One should always double-check the accuracy of important facts, regardless of the source. In general, popular Wikipedia articles are more accurate than ones that receive little traffic, because they are read more often and therefore any errors are corrected in a more timely fashion. Wikipedia articles may also suffer from issues such as Western bias, but hopefully this will also improve with time. For more information
  • Although the majority of edits attempt to improve the encyclopedia, vandalism is frequent.

  • If an anonymous or relatively new user changes a statistic or date by even a little bit, without justifying their edit, they are particularly likely to raise a red flag. If an individual continues to vandalize after being warned, then they may even be blocked from further editing.
  • keeps a full history of every change to every article
  • It is for this reason that readers must be particularly diligent in verifying Wikipedia against its external sources, as discussed above. It is also a good idea, if you feel uncomfortable about an article, to check its history for recent "bad-faith" edits. If you find a piece of uncorrected vandalism, you might even decide to help future users by correcting it yourself. That's a great feature of Wikipedia.
  • Wikipedia can be an excellent starting place for further research.
  • Students can compare information in Wikipedia with information in other encyclopedias or books in the library. As a general rule, contributors to Wikipedia are encouraged to cite their sources, but, of course, not all do. For the sake of verifiability, it is advisable to cite an article that has listed its sources. Most of our better articles have sections such as "References," "Sources," "Notes," "Further reading," or "External links," which generally contain such information.
  • The 2008/9 Wikipedia Selection for Schools is a selection of 5,500 articles deemed suitable for school children and has been checked and edited for this audience and protected against editing or vandalism. It contains about the equivalent content to a 20 volume encyclopaedia organized around school curriculum subjects, and is available online and as a free download for use by schools.
  • Educators can use Wikipedia as a way of teaching students to develop hierarchies of credibility that are essential for navigating and conducting research on the Internet.
  • Wikipedia's objective is to become a compendium of published knowledge about notable subjects.

5 Reasons Why Origami Improves Students' Skills | Edutopia - 59 views

  • origami
  • This art form engages students and sneakily enhances their skills -- including improved spatial perception and logical and sequential thinking.
  • Here are some ways that origami can be used in your classroom to improve a range of skills:

  • Geometry
  • According to the National Center for Education Statistics in 2003, geometry was one area of weakness among American students.
  • Origami has been found to strengthen an understanding of geometric concepts, formulas, and labels, making them come alive.
  • Thinking Skills
  • Origami excites other modalities of learning. It has been shown to improve spatial visualization skills using hands-on learning.
  • Fractions
  • Folding paper can demonstrate the fractions in a tactile way.
  • Problem Solving
  • Often in assignments, there is one set answer and one way to get there. Origami provides children an opportunity to solve something that isn't prescribed and gives them a chance to make friends with failure (i.e. trial and error).
  • Origami is a fun way to explain physics concepts. A thin piece of paper is not very strong, but if you fold it like an accordion it will be.
  • Researchers have found that students who use origami in math perform better.
  • STEAM
  • While schools are still catching up to the idea of origami as a STEAM engine (the merging of these disciplines), origami is already being used to solve tough problems in technology.
  • Additionally, the National Science Foundation, one of the government's largest funding agencies, has supported a few programs that link engineers with artists to use origami in designs. The ideas range from medical forceps to foldable plastic solar panels.
  •  
    Origami, the ancient art of paper folding, has applications in the modern-day classroom for teaching geometry, thinking skills, fractions, problem solving, and fun science.

FAQ For Librarians - Outreach Wiki - 51 views

  •  
    How common are mistakes on Wikipedia? Because Wikipedia is editable by anyone we can't guarantee you won't stumble across a mistake. But mistakes are fairly rare. External studies have suggested they occur at about the same rate they do in traditional encyclopedias. One thing that is great about Wikipedia is that it allows anyone to correct a mistake. A printed encyclopedia will need to wait for its next edition for a mistake to be fixed. On Wikipedia a mistake can be, and often is, fixed instantly.

      Where does this statistic come from?
  • Twitter is a rare case: it has arranged to archive all of its tweets at the Library of Congress.
  • Sometimes when you try to visit a Web page what you see is an error message: “Page Not Found.” This is known as “link rot,”
  • ...14 more annotations...
  • Or maybe the page has been moved and something else is where it used to be. This is known as “content drift,”
  • For the law and for the courts, link rot and content drift, which are collectively known as “reference rot,” have been disastrous.
  • According to a 2014 study conducted at Harvard Law School, “more than 70% of the URLs within the Harvard Law Review and other journals, and 50% of the URLs within United States Supreme Court opinions, do not link to the originally cited information.”
  • one in five links provided in the notes suffers from reference rot
  • 1961, in Cambridge, J. C. R. Licklider, a scientist at the technology firm Bolt, Beranek and Newman, began a two-year study on the future of the library, funded by the Ford Foundation and aided by a team of researchers that included Marvin Minsky, at M.I.T.
  • Licklider envisioned a library in which computers would replace books and form a “network in which every element of the fund of knowledge is connected to every other element.”
  • Licklider’s two-hundred-page Ford Foundation report, “Libraries of the Future,” was published in 1965.
  • Kahle enrolled at M.I.T. in 1978. He studied computer science and engineering with Minsky.
  • Vint Cerf, who worked on ARPAnet in the seventies, and now holds the title of Chief Internet Evangelist at Google, has started talking about what he sees as a need for “digital vellum”: long-term storage. “I worry that the twenty-first century will become an informational black hole,” Cerf e-mailed me. But Kahle has been worried about this problem all along.
  • The Internet Archive is also stocked with Web pages that are chosen by librarians, specialists like Anatol Shmelev, collecting in subject areas, through a service called Archive It, at archive-it.org, which also allows individuals and institutions to build their own archives.
  • Illien told me that, when faced with Kahle’s proposal, “national libraries decided they could not rely on a third party,” even a nonprofit, “for such a fundamental heritage and preservation mission.”
  • screenshots from Web archives have held up in court, repeatedly.
  • Perma.cc has already been adopted by law reviews and state courts; it’s only a matter of time before it’s universally adopted as the standard in legal, scientific, and scholarly citation.
  • It’s not possible to go back in time and rewrite the HTTP protocol, but Van de Sompel’s work involves adding to it. He and Michael Nelson are part of the team behind Memento, a protocol that you can use on Google Chrome as a Web extension, so that you can navigate from site to site, and from time to time. He told me, “Memento allows you to say, ‘I don’t want to see this link where it points me to today; I want to see it around the time that this page was written, for example.’ ”
