Being a Power Searcher
  • Finding stuff in cyberspace is not easy
  • The Internet, is an unorganised, unaccountable
    and unmanaged great steaming heap of information
    and knowledge.
  • Its great! As long as we know how to use it!!
  • Electronic spiders and robots are create subject
    gateways and databases.
  • There are other groups of people working together
    trying to organise links to books in the trying
    to record every title and send this information
    back to search engines.
  • There are also real people carefully looking for
    similar publications to pile into web portals
    (Wiki About).
  • So although cyberspace is a pretty messy place,
    if you know where to look you can find the right
    way, to find the right stuff. As long as you know
    where to look!

What is Net literacy?
  • Being Net literate
  • Too much browsing doesnt leave much time for
    reading. Too much cutting and pasting doesnt
    leave too much time for thinking. And too much
    reliance on Google doesnt leave too much time
    for getting it right. The secret is to use it
    when you need it, to use it the right way and to
    use it to get the best results for your needs.  
  • Getting the best results
  • So what can you do to get the best results, if
    you want to be Net literate how do you go about
    it? Here are few basic guidelines
  • Have sufficient tools (intellectual and
    technical) to be able to use the media
    effectively.
  • Know the right techniques to interrogate the
    medium
  • Understanding the different sources of
    information (online and the motivation behind
    publishing)
  • Develop a critical and informed approach to
    information searching

Why the net is good for learning
  • Good reasons for using the Internet
  • There are lots of good reasons for using the
    Internet for school and college work. Here are a
    few of them, (you may be able to think of more)
  • Its easy to access
  • It comes to you, you dont go to it.
  • Its contemporary and up to date.
  • It provides disintermediation (direct access to
    leading authorities)
  • The scale (Its huge)
  • It has great variety and allows access to
    alternative perspectives
  • Web browsers are easy to use
  • Search tools exist to help us.
  • When you look at this list there is one thing
    that stand out as important to all these
    characteristics and that is convenience, its
    easy to access and easy to use.

Why the net is bad for learning
  • Be cautious of information that you access online
  • There are a number of good reasons that you
    should be cautious of information that we access
    online. That is not to say that we cant use it,
    just that we have to consider a number of
    important issues before we do. The Internet can
    be bad for leaning for the following reasons
  • How do we know that the information that we find
    online is accurate
  • How do we know that the information that we find
    online is valid
  • How do we know that the information that we find
    online is complete.
  • How do you know who has published something
    online?
  • How do you know why they have published it?
  • If anyone can publish to the Internet how can we
    trust what we read?

Using the net and web
  • Something else to think about is how hard the
    Internet is to use.
  • Search engines seem simple, but are extremely
    complex technologies.
  • Web browsing is tiring and requires a lot of
    concentration. Web sites are often badly designed
    and leave users disorientated and confused.
  • Web pages themselves are often difficult to
    navigate and the temptation to simply cut n
    paste whatever we find leaves us open to
    plagiarism.
  • It is also hard to keep up to date with
    developments on the internet, so we can never be
    sure whether we are using the best information
    source or the best search technique.

7
Search skills
  • Searching skills are important because they
    enable you to
  • Adopt a systematic approach to finding what you
    want (This means you dont waste too much time
    retrieving references either from books or the
    web which are not related to your topic or
    project.)
  • Identify the general topic of the search and find
    out which are the important and current issues
    related to the subject
  • Identify key words for your search
  • Link these key words to produce a useful and
    relevant search
  • Broaden and narrow your search so you can focus
    on more specific aspects of your topic

8
Trusting online information
  • Objective techniques
  • When we start working out how to trust a web site
    what we can do is use a number of objective
    heuristic techniques to help us come to the best
    subjective conclusion we can. We can never be
    sure that we are 100 right, but the more we use
    then and the more we think about them the better
    we will do.
  • Authority and reputation
  • Do you know who wrote it and whether they have
    credibility?
  • Accuracy
  • Can you tell whether it is factually accurate?
  • Currency
  • Is it up to date?
  • Coverage
  • Is the source comprehensive or specialist?
  • Usability
  • Is the source easy to use?

How search engines work
  • Spiders, bots and crawlers
  • Are small computer programmes that visit every
    web page on the internet and sending the details
    of what they find back to the search engines that
    sent them.
  • These details could include the title of the web
    pages, the most frequent words on the web page,
    the content of the web page or the links on the
    web page.
  • Whatever is sent back becomes the raw information
    (or index) that the search engine uses to
    subsequently find a web page.
  • The thing to remember is that not every web page
    is crawled, not every crawler sends back the same
    information and not every search engine searches
    it the same way. Plus this is NOT a very
    sophisticated process it is about indexing the
    most pages, not the best pages.

10
Google me!
  • It is worth trying to understand why Google is
    seen by many people as the best search engine on
    the web.
  • Google tries to work out if one webpage is more
    relevant than an other one.
  • So that in a list of web pages on Google the most
    relevant is at the top the least relevant at
    the bottom.
  • They way that they have done this is to count the
    number of web pages that link to another web
    page. In that linking is one indication of the
    importance or relevance of the information in
    that page. Lots of links means very relevant. Few
    links means, little relevance.

Developing a search stratgey
  • 1. Before you start Think about search
    terms/expressions
  •  
  • 2. Turn this into one phrase e.g. David Beckham
    at Manchester United.
  • 3. Select your search tool (e.g. search engine)
    according to its suitability and start your
    search.
  • 4. Review the results from your initial search
    and see whether your search produced too many or
    too few results.
  •  
  • 5. Make appropriate changes to your search
    terms/expressions for example
  • Use different (but similar) words. Try a
    thesaurus if you have one.
  • Add or remove one of your concepts.
  • Try your phrase in quotation marks "David Beckham
    at Manchester United", this often makes a search
    very specific and can turn up good results when
    there are too many options.
  • Familiarise yourself with the advanced search
    features of search engine you are using
  • Try using Bollean operators a well established
    way of refining searches.

Web search checklist
  • Authority and reputation
  • Do you know who wrote it and whether they have
    credibility?
  • Is it an established organisation (e.g. BBC) or
    an established author (e.g. Stephen Hawking)
  • Accuracy
  • Can you tell whether it is factually accurate?
  • Is it biased? Does it represent one side of a
    story?
  • Can you cross check this information from
    another source
  • Currency
  • Is it up to date ?
  • Can you see a publication date on the source?
  • Should you be looking for a more recent source?
  • Coverage
  • Is the source comprehensive or specialist?
  • Is there a site map that shows the scale of the
    content?
  • Is it a credible source (see above - Authority
    and reputation)
  • Usability
  • Is the source easy to use?
  • Does it look well designed?
  • Can you easily see what information is available?
  • Can you easily navigate from page to page without
    being confused?
