  1. Unit 2 Surfing the Web How to use the internet safely, effectively, responsibly and resourcefully…

  2. Why should students learn how to use the Internet? There are three essential skills students gain by learning to use the Internet: 1. Communicating 2. Researching 3. Problem-solving These skills can be taught without the Internet, but most businesses apply these skills through telecommunication systems like the Internet. When students use technology, they show positive gains in achievement on researcher constructed tests, standardized tests, and national tests (Milken Exchange on Educational Technology)

  3. 7 things you should know before using the internet: • All students (and parents) must sign an AUP (Acceptable Use Policy). The AUP spells out exactly what Internet activities are allowed. 2. Students should never be left alone when using the Internet at school. Supervision is required. 3. Students should alert the teacher or librarian immediately if they encounter an inappropriate site. Encountering an inappropriate site can happen; problems arise if a student lingers at the site without alerting the teacher.

  4. Continued… 4. Students are not allowed to download large files, such as MP3's. It reduces the bandwidth for everyone trying to use the Internet. 5. Students should never give out their personal information on the Internet. 6. Students are not allowed to enter chat rooms or participate in online game playing. 7. Internet use is a privilege, not a right. The privilege can be taken away for inappropriate use.

  7. The 5 Important Elements of Electronic Information Sources: • Authority • Objectivity • Accuracy • Currency • Value

  8. Authority • Who is the author? • Is the author an expert? • Who is sponsoring the site? Is the sponsor reputable? • Are you led to additional information about the author or sponsors?

  9. Why??? • Anyone can publish anything on the web… • Hard to determine web pages’ authorship… • Even if signed, qualifications are given… • Sponsorship is usually not indicated…

  10. Objectivity • Why is the page on the web? Is it to inform, give the facts or data? • Is the page actually an ad disguised as information? • Is the page designed to sway opinion? • What are the intentions behind the page?

  11. Why??? • Goals of the sponsors/authors aren’t clearly stated… • Web often serves as a “soapbox”

  12. Accuracy • Where did the author get the information? • Is the information reliable and error free? • If there are links to other sources, are they reliable? • Is there a list of resources or a bibliography?

  13. Why??? • Anyone can publish anything on the Web… • Web resources are rarely fact checked… • No web standards currently exist to ensure accuracy…

  14. Currency • Is the page dated? • Is it current enough? • Undated information is no better than anonymous information.

  15. Coverage • What does this page offer that is not found elsewhere? • How in-depth is the material? • Is this resource comprehensive or selective? • Why is the information useful?

  16. Apply the 5 W’s prior to using a webpage as a resource: • Who wrote the page and are they an expert? • Where does the information come from? • What is the purpose of the site? • When was the site created or updated? • Why is the information useful to their research?

  17. Anatomy of a URL(Uniform Resource Locator)http://www.nasa.gov • anatomy of a URL • http:// HyperText Transfer Protocol (Internet address) • www: World Wide Web - most but not all addresses contain this; • Next part of the address is the name of the computer or the “server” (the Big Kahuna at Erwin!)

  18. org = organization gov =government k12._.us = public schools mil = military agency com = business edu = university net = network aus = australia http://www.nasa.govDomain Designator tells what type of group owns the server, for example:
