Filtering

The Internet allows access to a vast amount of information. This includes some information that is deemed unsafe and inappropriate. Should filters be utilized to minimize access to this type of information on school computers? How does this impact on intellectual freedom?

There are a variety of filters currently on the market, all of which use computer automation to prevent access to information. These filters use “five basic approaches to controlling and suppressing expressive content on the Internet: “bad word”, “bad phrase”, and even “bad syllable” stoplists, “bad site” lists, “bad topic” lists, site content rating systems, and “bad service” lists” (Schrader, 1999). The use of these approaches results in appropriate sites also being blocked because they may contain a word that is on the stoplist. Computers are not able to determine the context in which a word is used and are therefore unable to determine the actual appropriateness of a site. “No one disputes the need to protect kids from the harm that lurks online. What’s at issue is whether or not mandated internet filters are the best way to achieve these safeguards – or whether the filters aren’t up to the task and are actually interfering with the educational mission by obstructing use of important Web 2.0 tools.” (Villano, 2008)

The use of filters in my school district was not an issue I had previously considered. I have been fortunate in that any technology that I needed to access was readily available or was easily made available by contacting our technology support person. In other words, I lacked any knowledge of the negative impact of the use of filters and viewed filters as a means of keeping our network safe from the threat of viruses. It came as quite a surprise to read and take part in discussions that listed blogs, wikis, and other Web 2.0 tools as being blocked in other districts within the country and in other countries. I was curious then to find out what filters our district uses and if this has resulted in a loss of accessibility to sites. Our information technology person was able to supply me with the answers I sought. In our district, all school computers are filtered by Websense through the PLNet as mandated by the Ministry of Education. The purpose of using this filter as stated in a bulletin by PLNet is “to ensure students can use the Internet safely, with a reduced risk of visiting sites that contain inappropriate or harmful content” (PLNet, 2002). PLNet also recommends “that teachers and facilitators remain diligent in monitoring students use of the Internet” and explains the procedure when an inappropriate site is accessed through the filter or if an appropriate site is not able to be accessed (2002). As well as this filter, students are not able to download from the Internet (teachers are able to though) and individual sites are able to be blocked by our information technology staff. A site is blocked if a teacher or administrator requests it and is able to explain the negative impact this site is having on the education of our students. YouTube was recently blocked at one of our schools due to incidences of its misuse in the form of bullying. It is, however, still accessible at other schools in our district, as are all other Web 2.0 tools. As for student access to the Internet, our district requires that students and parents sign an “Acceptable Use Policy” and it is then left for individual teachers to monitor the use of the Internet within the classroom environment. Parents and guardians are also notified and permission requested when students take part in online activities such as class blogs or wikis.

How is intellectual freedom impacted by using filters to block information on the Internet? As a colleague of mine stated, it would be naïve to insist that filters should not be used at all. It is important to remember that one of the uses of filters is as protection against viruses which would wreck havoc with the network resulting in the inability to utilize the computers. However, when deciding on the use of filters “fear and misinformation should not triumph over logic and an agenda for learning” (Abram, 2007). The key components to using the Internet safely are education and communication, not censorship through the use of filters. Students have a right to access information. “Internet filters are an illusion. They impose a simplistic set of values on a complex and highly variable world of personal tastes, individualized family values, highly variable perceptions of age appropriateness, and widely varying thresholds of social tolerance” (Schrader, 1999). Overly restrictive filters do more damage than good. Educators and parents need to be responsible for teaching students about the Internet instead of relying on filters or blocking sites. “Educating students to make wise decisions and to evaluate the source and quality of information and communications they receive will provide them with a set of skills to use information efficiently and successfully” (McDonald, 2007). Educators have other options available to them besides filters when it comes to protecting students online while students are learning about the safe use of the Internet. With younger students, the uses of databases or pre-selected websites (trailfires and pathfinders) are methods to prevent their exposure to inappropriate sites. I have always had a twinge of doubt when I request that students do not access certain sites. Instead of restricting access, I would rather teach students responsibility and the ethical use of the Internet. In a span of six years with daily monitoring of student use on the Internet, I have only had a few incidences of misuse and have dealt with them directly. I am concerned about decisions then such as a school-wide blockage of YouTube which affects all students and teachers regardless of whether or not they had acted irresponsibly.

Filtering is important with regards to protection against viruses but its impact on student learning and intellectual freedom must be kept at a minimum. Students, teachers, and parents need to communicate openly about Internet use and learn to use it in a responsible, ethical manner.
