This activity and accompanying worksheet (see appendix) serve as scaffolding
for students' first Internet search. It is meant to foster the meta-cognitive
skills necessary for their subsequent searches. Please note that it assumes
at least a casual understanding of search engines on the part of the teacher.
Awareness, Attitude, and Skill
The Internet has been referred to as "the largest library in the
world." There are, of course, a number of differences between the Internet
and a library. These differences, while they might seem obvious to teachers
with Internet experience, are new concepts to most students. When students
do an Internet search they expect to turn up a few well-written sources
similar to those they might find at a library. What they instead turn up
is a large number of sources mostly unrelated to their topic. Related material
is often written by laypeople and contains more graphics then text. To make
more fruitful use of their time, students need to be made explicitly aware
of the differences between a library and an Internet search (as well as
gain the attitude and skills necessary to cope with the differences).
Awareness
Library material is searchable by author, subject, and title. Web pages,
on the other hand, are searchable by words contained within the text. With
this in mind, students need to spend more time considering key words for
their search. Is the spelling correct? Are any of them homonyms that might
pull up unrelated pages? I illustrate the importance of these pre-questions
by typing a student's topic (e.g., dolphins) into the search engine. I first
type the word with incorrect spelling so students see that it produces no
search results. I then type it correctly and point out a.) the sheer number
of results and b.) the number of results relating to the Miami Dolphins
(the American football team). Finally, I elicit two more key words to narrow
the results, and show how to restrict a search to avoid homonyms (in the
case of Yahoo, by typing "-football").
Attitude
Libraries contain material from "reputable" sources (e.g.,
authors and professors) that have been edited. A page on the Internet may
have been written by a scholar or an elementary school student. With this
in mind, students need to quickly scan a site to determine who designed
it and whether the caliber of the material is appropriate for their research.
To illustrate these points I search ahead of time for two sites per-taining
to a student's topic. I try to find a scholarly site and a noticeable opposite
(e.g., a professor's paper about dolphins' sensory abilities and a student's
book report about dolphins). I point out the obvious clues (e.g., the ".edu"
or ".ac" in the URL) as well as the more subjective differences
(e.g., ratio of text to graphics and use of color). The point here is not
to denigrate one site or the other, but to foster a healthy skepticism regarding
the research value of a site.
Skill
Libraries contain limited types of material (e.g., books and journals).
The Internet contains these as well as many new, often less informative
types of sources (e.g., link pages and graphic pages). With this in mind,
students need to quickly scan a site to determine whether it contains the
specific information they are looking for (as opposed to the more common
response of saving everything they find). To foster this more critical approach,
I first ask a student to scan a site pertaining to their topic. If the information
they are seeking is not immediately apparent, I demonstrate the use of Netscape's
"Find" feature. I type in the student's second and then third
key word, and ask them to determine whether the designer (of the Web site)
uses the words in the sense that they (the student) had intended.
One clear advantage of this activity is that students spend a fruitful
ninety minutes on the Internet and, for the most part, walk away with resources
that they might not otherwise have found. It is worth noting, however, that
the advantages are much more far reaching. "Narrowing the Topic"
and "Writing a Thesis Statement" are ho stages of the research
process with which my students have difficulty. The same meta-cognitive
skills that help facilitate the Internet search assist in these stages as
well. I have found that students are better able to articulate their narrowed
topics and thesis statements through working with Internet search engines.
Appendix: Accompanying Worksheet
Introduction to Search Engines
The Internet
- What kinds of material are available on the Internet (e.g., text, pictures)?
Who puts it there?
- What kind of material are you looking for? Be specific. For example,
information on Princess Diana's childhood and whether she went to college.
Your Search
- What three key words will you use?
a. Are you sure of the spelling?
b. Do any of these words have multiple meanings? For example, the word
"police" will also find "The Police" (the British rock
group from the 1980's-Sting was the lead singer).
c. If so, how will you avoid this? For example, by typing "+police
-sting"
- If you can't think of any key words, look at the list of categories
(and sub-categories) on Yahoo's index page. Which ones can you search under?
The Process
- Scan a site. Who designed it? Is it appropriate for your research?
- Does the site contain what you are looking for (see #2)?
a. Scan the site for the information. If you don't find it quickly...
b. Click "Find" to search for your key words. Are they used in
the way that you wanted?
- If you can answer "yes" to Numbers 5 and 6, save the pages
as text (remember to paste the URLs at the top of the text pages). If you
can't, click "Back" and return to your search.
