EVALUATING WEB SITES

Page 2: Evaluating Web Sites

Introduction If you are like most students, you are

relying heavily on resources from the Web for your research. Not all Web resources are created equal. If fact, there are great variations in the quality of the resources you access. The rule of thumb is "when in doubt, doubt." When you carefully select your resources, when you understand their strengths and limits, you create better products.

Page 3: Evaluating Web Sites

Discussion:

Why do we need to know who the author of a website is?

What are the characteristics of a "good" website with credible and/or authoritative information?

What are the characteristics of a "bad" website with unreliable and/or untrue information?

We will practice filling out the evaluation worksheet using this website

Page 5: Evaluating Web Sites

The Task You will be working in groups of four to

evaluate a group of Web pages on the topic of tobacco and smoking, or cloning or another topic of your teacher's choice. Each of you will be examining sites from a different perspective. You will be ranking the sites and comparing your rankings with the rest of the class.

Page 6: Evaluating Web Sites

Resources You will each be responsible for

completing an evaluation chart, focusing on the perspective you assume within your group.

You will select five of the following Web sites from one of these two controversial areas for you to evaluate.

Page 11: Evaluating Web Sites

The Process Your group of 4 students will evaluate the

selected Web sites.

Divide your group into the following four specialties to cover ground more efficiently.

Page 12: Evaluating Web Sites

Job Titles 1. Content specialist

2. Authority/Credibility specialist

3. Bias/purpose specialist

4. Usability/design specialist

Page 13: Evaluating Web Sites

1. Content Specialist:

Does the site cover the topic comprehensively? Accurately? Can you understand what is being said? Is it written above or

below your level of understanding? What is unique about this site? Does it offer something

others do not? Are the links well-chosen? sufficient? Currency: Can you tell: the date the information was created?

the publication date? the date the material was last revised? Are these dates meaningful in terms of the subject matter?

Would you get better information in a book? an encyclopedia?

Would you include this site in your bibliography?

Page 14: Evaluating Web Sites

2. Authority/Credibility Specialist:

Who is responsible for this site? Who sponsors it? Hint: truncate each section of the URL back until you are able to find the sponsor.

What are his/her credentials? Have the authors of the site cited their own sources? Are the

sources documented appropriately? What is the domain name? Does it end

in .com, .gov, .edu, .org, .net? Is it a personal page? Is that a meaningful clue in evaluating the site? (You can't always

judge a web page by its suffix. Some commercial sites provide solid information. Some university sites offer less-than-serious personal pages to graduate students.)

Who else links to the site? (You can perform a link check in AltaVista or Google by entering "link:webaddress" in the search box. Is it linked to by reliable sites? What do other sites say about this one?

Would you include this site in your bibliography?

Page 15: Evaluating Web Sites

3. Bias/Purpose Specialist: Why was this site created? (to persuade, inform,

explain, sell, promote, parody, other?) Is it a personal, commercial, government or

organization site? Is there any bias? Is only one side of the

argument presented? Does it appear that any information is purposely omitted? Is there a hidden message? Is it trying to persuade you or change your opinion? Is the bias useful to you in some way?

Can you distinguish facts from opinion? Would you include this site in your bibliography?

Page 16: Evaluating Web Sites

4. Usability/Design Specialist:

Is the site easy to navigate (user-friendly)? Is there a well-labeled contents area? Do all the design elements (graphics, art,

buttons, etc.) enhance the message of the site? Is there consistency in the basic formats of each page?

Are there any errors in spelling or grammar? Do the pages appear clean, uncluttered? Do the links on the site work? Would you include this site in your

bibliography?

Page 17: Evaluating Web Sites

Group Responsibilities Each student in the group should complete his/her own

organizer through the perspective they are assigned. As you examine each site, record any relevant information in

your chart/organizer. Begin to rank the sites 1 through 5, with 1 being the best. It may be easier to think to yourself, "Which are the two best sites in the set; which are the two worst."

Each group should select a recorder to take notes on group discussion and a discussion leader, whose job it will be to make sure each member gets a chance to contribute and to lead the group toward reaching a consensus about the best and worst sites.

Be prepared to discuss/compare your group's findings and rankings with the rest of the class during the class discussion period.

Page 18: Evaluating Web Sites

Evaluation

You will be evaluated on your group work, your completed organizer, and your participation in large group discussion using this rubric. Make sure your group is able to defend its choices in the discussion ranking the sites.

Page 19: Evaluating Web Sites

Conclusion

You will find yourself using the Internet for information. The Internet is only one of a variety of information options. Remember that journals, books, videos and other sources are available as well. Evaluating information is a skill you will be using throughout your lifetime.
