    • Evaluating Sources and Information
      by Sue Heraper
      Teacher Librarian
      Newbury Park High School
    • Things to think about as you decide whether or not a source is reliable…
    • How current is the material?
      What experience does the author have?
      Who published the material?
    • Who?
    • Authority is being an expert on a particular subject.
    • What?
    • Coverage is the extent of the subject matter.
    • Why?
    • Objectivity is a lack of bias or prejudice.
    • When?
    • Currency means contemporary, up-to-date
    • How?
    • Accuracy
      correctness
      in every detail, precision and exactness
    • Should you ever cite Wikipedia in a paper for class?
    • Should you ever cite Wikipedia in a paper for class?
    • Wait, wait! Wikipedia can still help you in your research!
    • Background information
    • Keywords
    • Links
    • References
    • Consider these scenarios
    • 1.You are researching the rain forest.
    • Which sentence demonstrates the author’s opinion about the topic rather than fact?
      1. People around the world have become more aware of rain forest destruction.
      2. Species are becoming endangered due to habitat destruction in the rain forest.
      3. People should be willing to give money to help save the rain forests.
      4. Deforestation hurts the environment
    • “People should be willing to give money to help save the rain forests” is an opinion, not a fact.
    • 2. You have located websites on the negative effects of drugs on teenagers.
    • Which site would best meet your information need?
      1. addictionscare.com -- A 24-hour addiction hotline in your community

      3. teenscenezeen.org -- Explains how to say “no” to drugs at a party

    • 3. You need
      to find information
      for a school project and one source must be a
      Web page.
    • Which question will NOT help you evaluate the sites?
      1. Who is the author of the information?
      2. How many people use the site?
      3. When was the site last updated?
      4. Is the author an expert on the subject?
