  1. 1. This Presentation is Based on Alan November’s Book Web Literacy for Educators<br />Presented by : Tricia Campbell<br />
  2. 2. Topics to Address<br />Definition of Internet, Link, and Homepage<br />How the Internet Works<br />The Components of a Domain Name<br />Matching Domain Extensions<br />What is Truncating?<br />How to Truncate a Web Address<br />What are Search Engines?<br />Take Careful Note<br />What is REAL<br />Read the URL<br />Examine the Content<br />Ask About the Author and Owner<br />Look at the Links<br />The Link: Command<br />Targeting Back Links<br />What Should My Students Be Aware of When Searching the Web<br />
  3. 3. Important Definitions<br />Internet : a network of many different computers all over the world that are connected<br />Link : connects you to another Web page instantly<br />When placing your cursor over a link, your cursor turns into a hand and the URL (www.) appears in the lower left of your screen <br />Homepage : acts like the front cover of a book or magazine, the starting point of a Web site<br />
  4. 4. How Does the Internet Work?<br />The Internet works by allowing Web Browsers to call up Internet Protocol (IP) addresses. <br />IP addresses have domain names so they are easier to remember and navigate.<br />Example : In the IP address http://www.cnn.com/ (cnn.com) is the domain name<br />
  5. 5. What Are the Components of a Domain Name?<br />Domain Names have two or three components, and are designed by companies to attract individuals to their site<br />Component 1 :is created by the site’s owner. No one can create a name if someone has been assigned to it already.<br />Example : The domain name cnn.com was purchased by CNN. No one else may use this domain unless CNN no longer purchases rights.<br />Component 2 : is called the TLD (Top Level Domain). It is designated for special groups or categories. <br />Example: .com, .edu, .gov<br />If a site is hosted by another country, a country code will be used in the extension.<br />Example : http://www.kiwirecovery.org.nz<br />Component 3 : called the Subdomain – always has a dot separating it from other components.<br />Example http://support.microsoft.com<br />
  6. 6. Match These Common Domain Extensions<br />Commercial <br />Educational Organization (most U.S. colleges)<br />Any Organization<br />Schools in the U.S. (not all schools use this)<br />Network<br />Government Agency<br />Military Institution (U.S.)<br />Academic Institution (not used in the U.S.)<br />a) .k12 b) .edu c) .ac d) .com e) .org f) .gov g) .net h) .mil<br />Answers: 1. d 2. b 3. e 4. a 5. g 6. f 7. h 8. c<br />
  7. 7. What is Truncating?<br />Truncating a Web address is a method for validating information on a Web site<br />Helps you navigate a Web site<br />Allows you to find the site’s homepage<br />Helps you locate more information about the site<br />
  8. 8. How Do I Truncate a Web Address?<br />Click at the end of a Web address<br />Delete all characters up to the left slash<br />Delete right to left until you end up with only the “domain name” (in most cases, the “homepage”)<br />Ex: http://www.sandiegozoo.org/teachers/classroom_activities.html<br />http://www.sandiegozoo.org/teachers/<br />http://www.sandiegozoo.org/<br />
  9. 9. What Are Search Engines?<br />Search Engines : use programs called robots or spiders to collect information about the World Wide Web. They are automated browsers that roam the web collecting text, titles, and meta-tags (words used by web authors to describe their page)<br />Search Engines<br />Provide “links” coming into a Web site<br />Give the title of the Web site<br />Give the URL (www.) of the Web site<br />Google : is the most popular search engine used today<br />
  10. 10. Take Careful Note<br />When using a Search Engine, search results may begin with “sponsored listings” (people pay to have their listing at the top of your results)<br />Either to:<br /> 1. Have their site be at the top of your results list<br /> 2. For business purposes<br />*When conducting searches, most students will click the first few results that appear on their screen<br /> This information may<br /> 1. be biased<br /> 2. be trying to sell you something<br /> 3. not have the best information<br />Therefore, students need to validate Web materials by using a four step program called REAL.<br />
  11. 11. What is REAL?<br />Read The URL<br />Examine The Content<br />Ask About The Author and Owner<br />Look At The Links<br />
  12. 12. Reading the URL<br />3 Important Questions to Ask When Reading a URL<br />Do you recognize the domain name? (look for clues about what a site is about or the quality of the site)<br />What is the extension in the domain name? (look for what type of establishment owns the domain name)<br />Are you on a personal page? <br /> look for: a name, <br /> Tilde sign (~)<br /> Percent sign (%)<br /> The words users, people, or members<br />
  13. 13. Examine the Content<br />Ask These Questions About Web Site Content<br />Is the information useful to your topic?<br />Are links provided? Do they work?<br />Is the site current? When was it updated?<br />Does the information appear accurate?<br />Does the information match information you found elsewhere?<br />
  14. 14. Ask About the Author and Owner<br />Questions to ask when viewing a Web site<br />1. Is the author’s name provided?<br />2. Is their a contact person or address?<br />Is the author’s biographical information provided?<br />Is the author an expert in this field?<br />What results appear when doing a “search” on the author’s name?<br />
  15. 15. Look at The Links<br />There are 2 types of Links<br /> 1. Forward Links : the name given to a link from your Web site to a page that is on someone else’s Web site.<br />Investigating forward links helps determine if a Web site has quality or false information.<br />Ask the following about forward links<br />What are the URL’s? (does every link contain the same domain?)<br />Do the domain names change? (Does the same person write all of the reference material?)<br />
  16. 16. Look at the Links<br />There are 2 types of links<br />2. Back Links: the name given to a link from someone else’s Web site to a page on your Web site.<br /> Investigating back links helps determine the quality of information on a Web site.<br />Ask the following about back links<br />Who is linked to the Web site? (schools? Commercial sites?)<br />Why are they linked? (why have they chosen to link to this site?)<br />3. What do other sites say about the material on this site?<br />
  17. 17. The Link: Command<br />To generate a list of back links:<br />Go to AltaVista (http://www.altavista.com/)<br />In the search box type link:and the web address<br /> Example : link:http://www.martinlutherking.org/<br /> (No spaces before or after the colon)<br />Click the Find button to see a list of sites linked to this site<br />Then ask the questions you need to gain perspective.<br />(If your AltaVista search produces no results, try truncating the Web address first)<br />
  18. 18. Targeting Back Links<br />Targeting a back link provides you with more specific information about a Web address.<br />To target a list of higher education sites that are linked to the Martin Luther King site:<br />Go to AltaVista (http://www.altavista.com/)<br />Click “Advanced Search” (to the right of the red “Find” button)<br />In the “all of these words box” Type “Martin Luther King”<br />Under “Site/Domain” click “Only .edu domains”<br />This list should allow you to see what higher education authors think about the Martin Luther King Web site.<br />
  19. 19. What should my students be aware of when conducting a search on the Web?<br />Almost anyone can publish something on the Web<br />Information on the Web may not be true<br />Links can lead to distracting or misleading information<br />Anyone with a credit card can purchase a “ .org (organization)” extension<br />Blogs are personal accounts and should not be used for academic research<br />A domain name may hide the real content of a site<br />A tilde (~) and a percent sign (%) in a Web address are signs that it is a personal account<br />Google uses a mathematical algorithm to produce search results, which means that results may not have anything to do with quality.<br />Ask “Why did these search results pop up?” instead of clicking on the first few results.<br />November,Alan.Web Literacy for Educators.California:Corwin Press,2008.<br />
