A while back I wrote about filters and the way that they have been used in schools. I ended my rant with a comment about how maybe the whole filter things might be becoming irrelevant anyway. Today gave me an example of that. A colleague of mine had to forward some information to a group of students before he talked to them about it, so he forwarded it to their e-mail accounts. Within a short while (less than 15 minutes) he went to talk to them only to discover that most of them had already read the e-mail on their phones. No need to access the school’s network to get that information. Seems to me that if we don’t get these students more access through our systems soon they’ll just go around it and that leaves me wondering how some people are going to deal with that.  If you really want to see great insight into this idea you should go to David Truss’ presentation on PODs in the classroom that he did for BLC 09.  It’s one of my favourites.

Sometimes it’s just too much

The last couple of weeks have been really rough, busy beyond belief, not to mention sick, so I haven’t been following up much on much on my posts, which is too bad but something that could not be avoided. My mind has continued to work even if my body has not always been capable so there have been many things that I have been thinking about, but today I think I’ll just concentrate on a couple of things that are updates of a kind of my previous posts.

I had an interesting conversation with a student about a week and a half a go regarding a couple of e-mails she received. To me they were quite obviously phishing messages masquerading as e-mails from her ‘bank’. It was interesting that she didn’t really check much before clicking on them, and in this one case, I will say at least the filter was there to block her access. When she asked me about them I was able to point out some of the obvious clues that made it obvious that it was a phishing message. I even showed her how to look at the url address that the link was pointed to and show that it was definitely not her bank’s website.  It was an interesting discussion with a student who was encountering these things just as she was about to finish grade 12.  Hopefully the advice I gave her will stay with her, but I did find it interesting that if not for the filter she might very well have gone on those phishing sites before she would have come to me with her questions.

The other thing I was going to talk about was what I was playing with to get this photo uploaded.  It’s called TagGalaxy, which I’ve mentioned previously but I am now more skilled at actually using and posting pictures.  What I really like about it is the fact that it is all visual.

When you reach the front page you can enter pretty much anything and as long as it shows up as a tag in Flickr you will be taken to a wonderful galaxy that shows your search in the centre and a galaxy of associated tags that look like planets, each one of which you can use to further refine your search.

When you have clicked down as far as you want to go click on the planet in the centre of the galaxy and it will zoom you into a planet that it populates with pictures.

TagGalaxy is a really useful way to collect pictures for all sorts of projects.  It also represents an opportunity to teach students about creative commons licensing and what it means to properly cite a source.  I have used it in my Social Studies class where I had the students send me the links of the pictures that they found that met the requirements of one of my projects.  It was fairly successful, although every time I use it I find out something new about how it its used.  The only disappointment I have had so far is that I have not found an easy way to search for creative commons photos without putting it in as the first tag which makes searching your real interest much more difficult.  Visual tools like this are what makes the Internet and web 2.0 so incredibly powerful.

Filters and other annoyances (well actually only filters)

This idea has been rolling around in my head for the last few weeks.  I have been trying to figure out how to write this with a feeling of anything less than sheer and utter frustration.  It is mainly because my friend Cynthia wrote me an e-mail on Friday asking me to describe what our filtering system is like that I’ve been provoked into action.  Clearly filters are an issue about which many of us in the blogosphere have written long and sometimes distressing entries.  I have no intention of rehashing that although I think that you should visit the following blogs from David Truss’ entries here and here to get an idea, although there are many more!  Beyond the fact that they are a reactive approach to controlling students web activities, rather than a proactive approach to the problem, I’m frustrated because ours really don’t seem to work all that well, and if we’re going to use them (as some educational directors resolutely maintain), shouldn’t they actually work?

They’re not very accurate.

First off let me say that I do understand that sometime and for some things there is a need to put in some form of restriction.  What I can’t figure out is why we don’t think about the sites that we block.  Maybe there should be some considered thought put into the reasons why something gets blocked rather than why they should be unblocked.

One reason why I would argue this is because I have seen a few sites blocked by the masters of the filters (whomever these people are) that simply have no reason being blocked.  Earlier this year one of my colleagues was doing a project that he had been doing for a couple of years on the topic of dictatorships.  He had his students use a website ‘the Dictator of the Month‘ which suddenly and inexplicably this year came up as inaccessible.  When I looked into it, it said that it was because it was obscene/tasteless.  What I would like to know is who decided this?  I mean I understand that it isn’t exactly the greatest website (in fact it has not been updated recently), but really obscene/tasteless?  I was able to get it unblocked, but when I asked why it was blocked, I was told that it was probably because of a mathematical algorithm.  I really didn’t get it, and still while I sit here looking at it I don’t get it.  It is my shining example of why the people who are doing the filtering are not doing the right job.  Some might say that this is a rare occurrence but I can remember a couple of times in the past few years where I had students working on World War II projects and the sites would come up inexplicably blocked.

Another reason why our particular filter bothers me is the fact that it has a strange aversion to feeds.  I have been trying to use Edmodo for my social studies class, but one of the things that I wanted to do was build up a collection of feeds, but whenever I have set one up I have found them blocked.  There is a note about advertising/banner ads, but I’m not sure how that applies to my feed.

I have been told by some colleagues that teach mathematics that the filters have an itchy trigger finger for sites even remotely related to probability, apparently they are freaked out by gambling.  Is this a good thing for our students?

Exactly how much time we have spent trying to correct this idiocies is not clear, but it makes me wonder if these are good value for the money.

Students get around them too easily

If they were effective students wouldn’t be able to get around them.  Only they do on a very regular basis.  I have seen all sorts of students on websites that they shouldn’t be.  Students shouldn’t be on Facebook (that’s a debate for another entry), but there they are.  They shouldn’t be on shooter games, yet I found one student playing a game called ‘Sniper Assassin’ apparently without even having to bother with trying to find a proxy to bypass the filter.  They also shouldn’t be on proxies but they are there as well.  I don’t know how many people in schools that have 3G phones, but I would say a lot of students do.  How effective is a filter at blocking 3G cell phone towers?  If I tell a student they can’t do something on one of the school computers, well that’s why they have a mini-computer in their pocket that doubles as a phone.

What’s worse is that these often block the teachers from accessing the most up-to-date or most useful information.  I had a colleague who was regaling me with how the filters ‘worked’ at his school, finally one day after expressing this frustration to a class, a student volunteered to help him access what he wanted.  This one time he agreed, and the student leaped over the filter and had the information inside of ten seconds.  While I may question the speed reported in the story, I have no doubt as to its general validity.  Again how is it that filters are supposed to work again?

Lastly I would point out that the Chinese government has tried desperately to erect an Internet filter, and with all the resources of the state behind it, it apparently doesn’t work well.

A final rant

This whole rant leaves aside the most important problems with filters that they are the wrong approach to the problem.  I guess what I have been dealing with is the fact that if you are a supporter of filters then they should work and work properly.  But the fact is they don’t, and that as technology marches forward they will become increasingly useless (there’s that 3G or 4G or whatever).  What frustrates me probably more than anything is the fact that no one in a position of power seems willing to have a frank and open discussion about this.  This last week the Calgary Board of Education announced that students would be able to use their cell phones in class, but they said that they would still control the websites the students had access to (make sure to read the corrections at the bottom).  Seems a trifle over-optimistic if you ask me.
