Why Filters? Which Filters?
Schools, governments and parents all around the world area currently talking about web filters. Why? They want to protect their children from exposure to inappropriate content that is all to easily popping up in internet browsers.
Current discussion suggests that governments should introduce free automatic filtering of the internet to block pornographic sites. Bailey writes that at the core of our technology infrastructure must be a strong set of access and filtering controls, detecting and preventing intrusion.
Leslie reports how Government tests have shown that often material that should be targeted will slip through, and much that should be allowed will be blocked. In addition to this, usually the better the filter is the more it slows down network performance (up to 86%). Miners writes that for this reason schools will need to look for ways to increase their bandwidth.
An article written by Wortham reports that Connecticut Attorney General Mr Blumenthal stated that almost 100, 000 convicted sex offenders (in America) are mixing with children on MySpace (shown by a subpoena), and for everyone of them, there may be hundreds of others using false names and ages. This scares me.
Bell discusses how some teachers strongly believe that some of the current filter systems block perfectly legitimate and valuable educational sources yet still allow inappropriate sites. She argues that teachers and principals are not given any power to unblock sites which causes stress for teachers who want to access them. This also restricts teachers ability to deal with cyber bullying issues as they arise since often teachers are unable to access sites such as MySpace to check out these incidents.
Bell suggests that children would be safer if schools reduced the strict filters and instead focused on teaching students good search skills and how to distinguish for themselves between good and bad sites. Bell also states that a current problem is students use the internet at school without having to think too much, they then go home where they are often unsupervised in their internet use, and suddenly become bombarded with spam and inappropriate sites.
Filters also provide a false sense of security for teachers and parents. Many sites manage to avoid becoming captured in filters and many guides are also easily available to give children step by step instructions on how to get around filter systems, E.g. Youtube clip.
In addition to this, teachers should teach children (and learn themselves) how to judge the reliability of sources of information found when surfing the net. Descy writes an article titled “Of course its true.. I found it on the web!” gives some attributes to look for when evaluating a site for accuracy of information, these are, authority of author, is the author/site biased?, credible references and is currency of information. Descy also suggests teachers give students many different examples of good and bad websites to help prepare them to critically evaluate information they see on the web.
As a teacher I realize the need to not only set up a filtering system that will help protect children from inappropriate internet sites, but also to teach children appropriate behavior and communication on the internet. Children need to be warned about people such as these, but more importantly children should be taught the skills to equip them with the knowledge of what to do incase they do become involved with such people or sites. I plan to always be alert when allowing children to use the internet, monitoring them and not leaving them alone. I think it is important to teach parents about the dangers of the internet, but also to equip them with the knowledge and skills to help set up a safe environment for their children to use the internet rather than to scare them into banning the internet in the home. It is disappointing that we live in a society that needs such filtering, however it is a reality and as a teacher I will do I all I can to protect the children whom I teach.
