Web-Filtering Software: Censorship
or Good Sense?
What's the Policy?
As more and more schools provide
students with access to the World Wide Web, parents and teachers have become
concerned about how to protect students from exposure to inappropriate web
sites. As a result, many schools are adopting
acceptable-use policies (AUPs),*
which are signed by teachers, students, and administrators and state the guidelines
for the responsible use of computer technology.
Even with a strong acceptable use policy, some schools and school districts
may not wish rely on students alone to behave responsibly. These administrators
may choose to also use web-filtering software.† This software disables access
to web addresses that are known to be inappropriate, such as pornographic or
hate sites. The software updates the filters daily by searching the Web for
new inappropriate sites. Although not foolproof, web-filtering software is one
way to monitor the burgeoning amount of information on the Web and to protect
students from harmful information.
How Does It Affect Teachers?
When teachers assign students
research projects using the Web, they need to realize that when web-filtering
software is being used at school, the students may be unable to access certain
sites that would be relevant to their research. On a day-to-day basis, teachers
must be aware of the parameters set for the web-filtering software their schools
use. Suppose, for example, that you are teaching a unit on AIDS and you have
designed an activity in which students use the Web to search several sites
to find up-to-date scientific research. All the sites work when you develop
the idea at home, but at school, none of your students can access them. The
reason is that your assignment is incompatible with the web-filtering software
in use at your school. On the other hand, if your school does not use web-filtering
software, and you assign your students to do a search on AIDS in class, they
may come across inappropriate and/or dangerous information.
What Are the Pros of Web-Filtering
Software?
From pornography to hate literature
to directions on how to make a bomb, the Web is an unknown and unmonitored
entity with the potential to cause extreme damage. The global nature and design
of the Web make it almost impossible to enforce any code of moral or academic
ethics.
Another problem is
accuracy. No registry is required to publish a web page; anyone with access
can create his or her own home page, and the information it contains is not
necessarily subject to accountability. Students are quick to search, find,
cut and paste without bothering to evaluate the source and the content. This
lack of quality control concerns many teachers and makes them hesitant to
use the Web without "safety nets," such as web-filtering software, in place.
One additional consideration
must be the school's liability. Some teachers and administrators worry that
if a child encounters dangerous information and then uses that information
to act unlawfully, the school could be held responsible. They prefer a restrictive
web-filtering software and an AUP that errs on the side of restraint to protect
the school from liability as opposed to the risks of allowing unrestricted
access to all the information available.
What Are the Cons?
Some
schools see problems with relying on web-filtering software: the filtering
technology is not perfect, and schools that rely on it are more vulnerable
if it fails. The use of filtering software also brings up censorship and First
Amendment rights (see the
chapter entitled "What Are the Ethical and Legal Issues Facing Teachers?" for more on this subject).
Some teachers believe that even though the Web contains a great deal of inappropriate
information, students should have unlimited access but be closely monitored.
Teachers need to instruct their students in ways to evaluate the authority
of web sources‡, monitor students when they use technology, and enforce acceptable
and responsible use. This strategy models trust and teaches proper researching
skills instead of relying on an imperfect filter and withholding valuable
information.
What Do You Think?
- In this scenario, if your school were reviewing its decision to use web-filtering
software, how would you vote? Explain.
- Would your decision on web-filtering software change if you knew that the
software collected data on students' web-use habits for the company that created
it?
- How would you answer a parent who complains that her child came across
pornographic information while researching the project you assigned?
- How would you modify your lesson about online searching if a parent refused
to sign his child's permission slip to use the Web at school?

to screen content and prevent unsupervised browsing.

For Further Reflection:
- Which method or methods for helping students avoid undesirable web material
appeals to you most: educating students about web safety, requiring students
to agree to acceptable use policies, providing guidance through hot lists,
using web-filtering software, or whacking sites from the web entirely? Why?
- What would you do if you came across some students who were purposely looking
for inappropriate material on the school's computer?
