    Lesson 8 Evaluating Websites Lesson 8 Evaluating Websites Presentation Transcript

    • Lesson 8 – Evaluating Websites I’m Wilf . I will tell you “ w hat I ’ m l ooking f or” in this unit. This means I want to know if you can do what I am looking for by the end! I’m Walt . I will tell you what we will be learning, after all: w e a re l earning t o…work well in Meldrum Academy!
      • Walt says: “In this unit we are learning :
        • What to look out for when evaluating a resource
        • How to judge whether a resource is useful for your investigation.”
      • Wilf says: “What I’m looking for is that by the end of this unit you should be able to say:
      • ‘ I can…
        • Identify where a piece of information ‘comes from’
        • Judge how accurate a resource is likely to be
        • Recognise differences between fact and opinion
        • Spot bias and misinformation in a resource
        • Judge how useful a resource is for my investigation’.”
    • Evaluating information? You’re already doing it!
      • Weather forecast
      • Newspaper reports
      “ Tomorrow will be warm and sunny throughout Aberdeenshire …” “ New research published today suggests that most pupils enjoy exams”.
    • All day, every day!
      • Television
      • Advertising
      “ Heavy industry is destroying our planet!” “ Our jeans will make you irresistible and everyone will fall in love with you!”
    • Online information Anyone can publish on the Internet, whatever their intentions …… To inform … To sell you something … To persuade …. To fool you! For fame ….
    • So, is it Great or Garbage?
      • Evaluation criteria:
      • Who wrote it?
      • Is it accurate?
      • Is it biased?
      • Is it useful?
    • Who wrote it?
      • What organisation or individual is responsible for the resource?
      • Look for clues in the url (.com .gov .org, etc)
      • Are they a recognised expert in their field?
      • Is there an ‘about us’ or ‘contact us’ section on the website?
      • If in doubt, Google the author to see what else they’ve written
    • Is it accurate?
      • Does the information ‘fit’ with what you already know?
      • How up to date is the material?
      • Do the ‘facts’ check out?
    • Think about Wikipedia
      • Wikipedia allows anyone to contribute an article
      • Wikipedia welcomes amateur contributors
      • No formal training is needed for posting an entry
      • Wikipedia entries do not list authors’ full or even real names
    • Is it biased?
      • Few sources of information are purely factual – these are mainly encyclopaedias, dictionaries, reference works
      • Most sources contain an element of opinion or bias – some more than others!
      • Newspapers, television broadcasts, political statements, scientific research – all represent different points of view
    • Points of view
      • Take the issue of animal testing, for example. How many different points of view are there?
        • Drug companies
        • Animal rights groups
        • Medical professionals
        • Political groups
      • Can you think of any other examples?
    • Clues about bias
      • Bias can be useful in an investigation, but it can also be misleading. Here are some points to look out for:
        • What sort of ‘language’ or tone does the author use?
        • What other sites does the resource link to?
        • Is there any advertising on the page?
    • Is it useful for my investigation?
      • When you are doing an investigation, ask yourself:
      • Is the information relevant or related to your topic?
      • Is the site well organised and easy to navigate?
      • Is the material written at the right level?
    • Summary …
      • Remember:
        • Who wrote it?
        • Is it accurate?
        • Is it biased?
        • Is it useful?
