Evaluating Internet-based Information:
David Warlick is a former history teacher and is
|This kind of scenario has many educators concerned about
using of the Internet as a reliable resource for academic information. The fact is that
almost anyone can now publish on the Internet, while only a few years ago, nearly
everything that you read was filtered by editors and presented based at least on its
economic value if not for its scholarly worth. Today, anyone with an axe to grind can do
so over the Internet and with a look of authority. At the same time the Internet is
increasingly becoming the first and preferred source of information for many of us.
In response to this concern and the scenario above, I believe that the presence of inaccurate and biased information on the Internet is not our primary problem. The information and points of view have not really changed, it is the tools that have changed. Today, our students use professional and sophisticated information tools and global electronic networks to complete their assignments while most of us used pencil and paper and the information resources that existed in our school library. While we did our work with what could be compared to a $12 box of Lincoln Logs, students today have at their disposal professional tools and virtually limitless materials, as if they have an entire Builder's Supply warehouse to work from. While we assembled our reports with children's building blocks, today's students can craft their information products with word processors, enrich them with multimedia mined from the Internet, and empower them with hypertext. Their work can be compelling and it can be published to a global community.
The real problem with the scenario above is the assignment. The problem is that we are still, by and large, giving Lincoln Log assignments -- "Write a report about the Holocaust." These advanced and powerful capabilities that are increasingly available to our students beg for a different kind of assignment. Writing a report about something has as its goal the demonstration of gained knowledge. Yet gaining knowledge becomes only a small part of what students should be learning to prepare them for a world where knowledge changes and information grows at dizzying speeds. In fact, in the information world, their jobs will be to help in growing knowledge by becoming information builders.
From the perspective of the builder, our students have aisles of information processing tools to choose from and an Internet warehouse from which to choose building materials. The difference is that the builder, in the middle of Builder's Supply, has a task or project in mind, something that he or she plans to build for the enjoyment and convenience of others. Our builder has a goal behind his or her selections of tools, lumber, and nails.
Goals-based projects have a variety of benefits:
|Goals-Based Evaluation||What do goals-based assignments have to do with evaluating
Internet resources? Let's return to the builder's analogy. One of the many things that my
father taught me is that when you are building something in the workshop, the number one
key to success is using the appropriate tools and materials. Walk into any "Builder's
Supply," and you have a virtual Internet of tools and building materials available to
you. As you examine them individually, they are not judged as good or bad, but simply
appropriate or inappropriate for specific building projects. Our task, as the shopper, is
to select the tools and materials that are appropriate to our goals.
Traditionally, Internet resources have been evaluated from the perspective of the information itself and it's source. This usually involves some type of checklist that puts all Internet information through the same sieve, evaluating each based on the same criteria. Here is part of a checklist that I developed several months ago after reviewing some of the many evaluation forms available on the Internet.
It is implied that if you end up with a sufficient number of "Yes" checks, then the information is good and you use it. If not, then the information is bad and you never use it. Some of these evaluation forms can be quite long and picky, asking researchers to check spelling and grammar. But the result is the same. The resource is either stamped "Good" or "Bad," and this approval has little to do with the work that the student is doing.
As students' information products should be based on teacher or student established goals, evaluating the material that they consider using in their products should also be goals-oriented. Rather than judging the material based solely on itself via an examination instrument that has nothing to do with the students work, it should be judged from the perspective of what the student wants to accomplish.
From this standpoint, we would not ask, "Is the author qualified?", but, "What aspects of the author's background help me accomplish my goal?" Under certain circumstances, a web page published by a neo-nazi organization might actually be appropriate for an assignment, while other resources, produced by people with credential would not. It depends on what the student wants to accomplish.
This approach actually serves three interesting purposes.
|Information about the Information||The second benefit is of particular interest as
Internet-based information meets with increasing suspicion. In the print-based world, it
is only necessary to mention the author's name and a vague reference to the source.
"John Robinson said in his book, Acres of Sound, that
". This plus a
standard citation placed at the bottom of the page or in the bibliography alone is
sufficient to render the information fact.
This will not be enough justification for information gathered from the wild Internet. Other rationale will be needed which might read like this:
This more elaborate explanation of the information's source lends it credibility when a mere URL would not. Therefore, part of the evaluation process should be to identify and collect this sort of supporting information about the information, as justification.
|Internet Evaluation Form||The form below has been created to help students evaluate Internet
resources based on the goal(s) of their work. It begins with a statement of the student's
goals, and then follows through with the collection of specific information with
explanations of how the information supports the resource in terms of the student's goals.
Another assumption provides an additional basis for this form. As students are researching the Internet, we might safely assume that they are using a computer. Therefore, they should also be using a computer-based form for their evaluation and collection of information. This form is designed to be used as a computer file. The student will come to the computer with a disk, and will complete the form by typing their information into the appropriate spaces or by copying and pasting the information with the Edit menu.
The form that follows is available in three formats, Microsoft Word97 for Windows, Rich Text Format (RTF) for importing into other word processors and operating systems, and text for computers will limited memory where only NotePad or SimpleText can be run along with the browser.
This form is available for download as a zip archive (.zip) file with this evaluation form. It can be decompressed with WinZip for windows computers and the latest version of Stuffit Expander for Mac OS. The file decompresses into three version of the above form. The Microsoft Word version (.doc) is for Word97 on Windows 95. The rich text format (.RTF) version can be opened into most other word processors, either Windows or Mac OS. The text (.txt) version is for computers with limited memory. This file can be opened into NotePad, WordPad, or SimpleText.
|Description of the Form Sections||Project Name:
The project name labels the evaluated resource assigning it to a specific project. Asking students to assign a project name can also help them to think through their goals and to apply an identity to the project based on those goals.
What is the goal of your project?
Here the students will enter the goal(s) of their project in words that make it easy to associate other information resources to the goal(s) at hand. Again, the goals should be behavioral. For instance, how do you want to effect:
This is the name of the web site, ftp file, picture, graph, or map file.
Enter the URL or electronic address of the Internet resource being evaluated and retrieved so that it can be revisited at a later date.
Find the name of the person who authored or compiled the information. This is not always the web master of the page, and it may be necessary from time to time to ask for the author's name from the web master via e-mail. Another piece of information that might be valuable here is the author's home page URL. In many instances it is also good to have the name and e-mail address of the site's web master. He or she is usually the first contact point for the information being published.
This is the organization that maintains the web or ftp site, or who sponsored the publishing of the information. In many cases the publishing organization and the author are the same. Again, the URL for the organization's home page might also be included in this space.
What aspect(s) of the author's or publishing organization's background helps you accomplish your goal?
This will be information about the author and the publishing organization that relates to the generation and publishing of the Information and that relates to the student's goals. This might also include special research in which the author is engaged or previous projects. Another example might be the mission statement of the publishing organization. It could also involve the research that lead to the information and other studies being conducted by the author. Students should examine this information and pull out aspects that are relevant to the topic and that lend credence to the information and its relationship to the student's information product goals.
Date of Publishing:
Enter the date that the information was originally published. If it was published separately in print and this information is available on the web site, include this date as well.
Date of Last revision:
This information is not always available. In some cases information web resources are not updated, just published. This information will, however, be important for time sensitive data.
How does the date of the information's publishing or latest revision help you accomplish your goal?
In many cases the most recent the information is, the more valuable it is. However, this is not always the case. Sometimes, depending on the goals of the information product, information generated in 1942 or 1066 may lend it more valuable to the goal(s). In this section fill in any information about the date of generation, publishing, or revision that enhances the information product in relation to its goal(s).
Information Format (text, columnar, picture, movie):
Enter the format of the information here.
How does the format of the information help you accomplish your goal?
Information format is of greater importance than most people believe. In information rich environments, it is essential that information communicate itself as effectively as possible -- and this involves format. Some types of information deliver themselves into the understanding of readers by being displayed in columns and rows of text or numbers. Others communicate better as graphs, and others as paragraphs of text. Another consideration in this section is the transfer of information from the Internet from one format to another. The information may come as tabular data, but you need to convert it to graph to more effectively communicate the information. All of these notes should be entered in this section of the evaluation form.
One of the advantages of retrieving digital information from the Internet is the fact that it can conceivably be accessed, manipulated, included in the information product, and published without ever being printed to paper. Data can easily be copied from a web page or other Internet tool and then pasted into this section. If you are using MSWord or other more sophisticated word processor (especially if you are using a Macintosh), even pictures can be copied from the web and pasted into the evaluation.
How does the content of the Information help you accomplish your goal?
Why is this information important to accomplishing your goals? This is perhaps the most important part of your evaluation and should apply directly to the goals of the student's information product. Consider that this may be included in the product itself as supporting information about the information.
MLA-Style Citation Template:
You want to get all of the information about your resource that you can at one time, so that you don't have to return to locate specifics for your citation or for other reasons. This section provides a template for a standard MLA-style citation. Simply highlight each element (last name, first name, title of the article, date published, etc) and then replace it with the appropriate information from the web page. When you are assembling your information product, all you have to do is copy this citation from your evaluation form and paste it into your product.
|Conclusion||The Industrial Age has resulted in a glut of manufactured
products that find their way onto our store shelves, mail order catalogs, and into our
homes. We see them and purchase them because they have value to us in some way. When I
took shop in 1966, we learned the skill of producing items of wood and steel, but the
items that we produced had value to us or to family members. They were built to be used.
In the Information Age, information will be the commodity. Our world will be rich with it,
and information will compete with other information to be used in ways not dissimilar to
the competition among automobiles and washing machines.
Therefore, in the same way that the chess boards, and book shelves that we built in shop had goals of value that created context for the skills we were learning, the information products that students create today should also have goals of value and lend context to their learning.
Assignments should include:
