Personally, I think that filters on
school computers make sense, but they have to be done well. There
are, of course, some sites that students shouldn't have access to
during school hours or within the school building. Such sites would
include sexually explicit sites, those with criminal activity, or
even social media sites as they could distract from learning. On the
one hand, it's important to keep the learning environment focused on
learning. On the other hand, it's also important to keep in mind the
limitations that broad strokes filters place on learning. For
example, a broad stroke ban on the word “breast” in school
computers may, in theory, seem like a good way to keep sexually
explicit materials from students, but may in practice lead to
frustrated students trying to find information about breast cancer.
The easiest method to filter a
school's computer is to ban keywords, such as “breast” or “porn”
but the word ban is very simplistic and it doesn't discern the
difference between inappropriate sites and medical sites using the
word “breast”, or between explicit sites and a news article
mentioning “porn” which may still be appropriate for students,
especially older students. A truly simplistic word ban may also block an entire news site based on a banned keyword in one article. A high school student might write about a
child pornography case for a civics or journalism class, whereas the
same articles would be inappropriate in a setting with younger
students.
Consequently, a more fine tuned
approach is needed. While a blanket ban on words like “cocaine”
would work well in an elementary school setting, it might prevent
completely appropriate science or social studies related searches in
middle or high school classrooms. A parental controls app, such as Blocksi, that uses
a more complex vetting system would better fit the needs of a middle or high
school. Even then, there are always exceptions that will
come up in every school. The app may malfunction, or it might be
overly strict for the school. A certain assignment may present a
challenge to the block.
As far as social media sites, there
are still exceptions. Mainly, the exception should be made for
YouTube, which certainly has applications within the classroom. I
could also imagine a project for a civics or citizenship type class
about social media and the ways in which laws have to change to
accommodate the technology and its uses, including the unfortunate
side effect: cyber bullying. For the uses of that class, it would be
a good idea to temporarily unblock the social media websites so that
students could access these sites for observation.
There is also the issue of proxy
servers that will allow students to get around their schools' blocks.
These are usually only an issue in high schools and middle schools, as younger students usually don't know how to look for them. As such, the
schools need something more than a url block on each type of site.
The filtering system also needs to be on more than one browser, otherwise a student could use or download a different browser to completely circumvent the school filtering systems.
Generally, schools need these blocks
to maintain an education focused environment. Just as a teacher
would not allow a student to read comic books or pass notes in class,
the school needs to prevent as many distractions as they can. Given
the technology that now exists, and how necessary it is to students
and their education, these blocks need to be sophisticated. It would
be worthwhile for each school district, if not the individual
schools, to invest in at least one IT professional who can monitor
student computer activities in the school buildings. If the budget
allows it, each school should really have at least one IT manager.
Not only would having an IT tech on hand help to prevent students
from breaking through the schools' blocks, but they would be able to
catch any virus attacks on the school more quickly, and they would be
there to help students, teachers, and other staff with any technical
problems arising from the technology we now use in education.
