Yeah one person watching porn in class will blow it for everyone. What's to stop someone from looking at status updates in class unfiltered? There are also ways to dodge the filter like proxies. Even if the filter blocks proxy sites, anyone can connect a VPN. Anyone can go on the play store and download a proxy. Plus there are still the unblocked sites.
A high school is a place for learning and not doing something that a student shouldn't be doing. When it comes to inappropriate websites, like adult websites, then yes those types of sites should be blocked off. However, anything else besides that should be just fine as long as the teacher says it is alright. Teachers are in charge of their students and they should decide what is fine to do and what is not fine to do.
High schools need to censor the Internet because students like to do goofy things, and look at inappropriate things to be funny. On top of that they will also use it as a means for social connections like getting on facebook, twitter, tumblr instead of actually doing their homework like they are supposed to.
Sure, there's stuff out in the world that kids REALLY don't need to see. I get that. But when you're trying to look up a Khan Academy video on YouTube, only to find it blocked, well, people are going to get upset. Even if you're trying to get on an educational website for research, if it has anything in the search that's suspicious, it'll shut you down immediately.
Some things might be O.K. To censor like porn sites, but often restricting some online sites because of key words can restrict the students ability to gain knowledge and grow. Censorship also intrudes on American rights like Freedom of Speech and Freedom of the Press. Finally, censorship can prevent research.
Honestly, parents are so pathetic it makes me laugh.. They want to protect their poor children from cyber-bullying or finding out what pornography is or any of that stuff. You should let them experience that when they are young so when they are older they know how to deal with it. Parents are ridiculous.
Yes, maybe schools should censor things like porn, but if the site has a sear word in it and you block it, that's just restricting what might be a really good site with good and useful information. Students need the freedom to hear other peoples views on the subjects they want to know about, but they can't if administrators think that all students are just goofing around and not doing their work ever. Which not every kid does.
