Website Evaluation Website Evaluation Presentation Transcript

  • Access, Evaluate, Use How to Research Effectively Using the Internet EVALUATING WEBSITES By: Mrs. Unangst, Your Information Specialist
  • What makes a web page useful for research? Web page
  • Which URLs should I choose?
      • URLs ( U niform R esource L ocators) have a specific structure. Knowing it will help in evaluating which sites to use.
    • This is the format of the URL:
    • protocol://host/path/filename
    • For example, this is a URL on the home page of the House Committee on Agriculture of the U.S. House of Representatives:
    • http://www.house.gov/agriculture/schedule.htm
    • Structure of this URL:
      • Protocol: http
      • Host computer name: www
      • Second-level domain name: house
      • Top-level domain name: gov (this is your clue!!!!)
      • Directory name: agrictulture
      • File name: schedule.htm
  • Several top-level domains (TLDs) common in the USA:
      • .k12 –schools- CAUTION- Could be a class project
      • .com –commercial enterprise- CAUTION-advertising ahead
      • .edu –colleges- CAUTION- the ~ means a personal site within the college domain (i.e. college student)
      • .gov –government- Most reliable
      • .mil –military- Reliable
      • .net –network access provider- CAUTION-Check for bias
      • .org –usually nonprofit organization- Reliable but check for bias
  • New domain names were approved in November 2000 by the Internet Corporation for Assigned Names and Numbers (ICANN): .biz, .museum, .info, .pro (for professionals) .name (for individuals), .aero (for the aerospace industry), and .coop (for cooperatives). These domain names are beginning to become available. .co is being used by Overstock.com now in commercials
  • Country Codes: (the site may not be in English)
    • EXAMPLES:
      • us = USA
      • uk = United Kingdom
      • gb = Great Britain
      • au = Australia
      • fr = France
      • es = Spain
  • I hyper-linked to a site – how do I know it’s a good one?
    • The 5 W’s of Evaluating Internet Sites:
      • Who is the author or sponsor? Is he/she an expert? Can he/she be contacted?
      • What information is included on the web site?
      • When was the site created or updated?
      • Where is the source of the information? Is there a bibliography?
      • Why was the info written? What is the site’s purpose? Is it fact or opinion?
  • Questions To Think About -
      • Does this site address the topic you are researching? Was the page worth visiting?
      • Do you have good reason to believe that the information on the site is accurate? Do authors provide any supportive evidence for their conclusions?
      • Who are the authors of the Web page? What gives them their authority or expertise to write? Who is responsible for the site? Is this a commercial, governmental, personal, or academic Web site?
  • More Questions to Ponder -
      • What is the purpose of the site? Is the main purpose to inform, to persuade, or to sell you something? Do you understand what is being said? What do you think has not been said that should be addressed?
      • Is the site well organized? Are there misspelled words or examples of poor grammar? Do the links work and are they evaluated or annotated? Do they send you beyond the site to other reliable sources of information? Does the site offer anything unique or does it tell you little more than you could find in an encyclopedia? Are the graphics on the page clear and helpful or distracting and confusing?

  • When to Use the Evaluation Sheets
      • When evaluating pages on the Web
      • Let’s take a look at West Fargo School District’s Library Web Resources (go to the link below, choose “Library” and then “Search Model” for handouts):
    • http://www.west-fargo.k12.nd.us/schools/wfhigh/library/searchmodel/
  • Suggestions for Successful Internet Assignments
    •   Most students prefer using the Internet for research and recreation. They will spend countless hours searching and surfing. However, they may not completely understand the Internet's strengths and weaknesses as both a research tool and as a general source of information. Here are some suggestions to help you design effective and successful Internet learning experiences.
      • Provide Guidance If you know the URL, provide it. This way students should have no trouble getting to the web site.
  • Suggestions for Successful Internet Assignments
      • Plan Ahead Check to make sure that the site is still working a few days before giving the assignment. Web pages have a strange way of vanishing without any warning. Alternately, provide several different sites to visit just in case one or two disappear.
      • Request a Hard (Backup) Copy Have students make a print copy of the web site (Netscape automatically prints the date and time of access) or else ask them to note the date and time they used the site. This should help clear up any problems if the information changes all of a sudden, leaving some students with out-of-date material.
  • Avoid Busywork Ask students to do more than just fetch something off the Internet. Require them to visit one or more sites or search by topic. You might have them compare or evaluate several similar sites. Give them a list of criteria to follow for their comparison or evaluation. If assigning a research project that either wholly or partially includes internet sources, ask student to include their search strategy as a component of the research project. Request that they analyse methods they used to refine their search and what made the search more and less successful. Suggestions for Successful Internet Assignments
  • Draw on Their Knowledge When assigning students to create a bibliography of web sites (webliography) Ask students to come up with their own method of evaluating and assessing web sources. They could list the criteria they feel is most important in site selection and inclusion. Suggestions for Successful Internet Assignments
      • Don't Assume Student Expertise Often students cannot always differentiate between advertising and information on a web page, especially undergraduates and those unfamiliar with the web. Often students accept any information found on the web at face value. As above, provide them with the tools to evaluate the web sites they do find.
    Suggestions for Successful Internet Assignments
      • Use Established, Trustworthy Web Guides/Directories You might want to use the library's Internet Resources as either a starting point for students or else as a link from your class web page. Other invaluable web directories include: Librarians Index to the Internet at http://www.lii.org http://www.lii.org
