Wired for distraction

There is a very good feature article in the New York Times title Wired for Distraction that reasonably - without hysteria, outlines problems some students are experiencing in balancing their online lives. It describes how some students are almost obsessed with maintaining frequent contacts with friends via Twitter and Facebook or games to the point that they cannot focus on other tasks that are not so immediately fulfilling. Unlike many popular press articles on this topic, they point out that this only affects a minority of young people, but is nevertheless a significant issue. For those involved with secondary students in particular, it is a good read.

The answer, it seems, is that teachers (and parents) need to help students find balance and manage their priorities. Surprise! Who would have thunk it?

Google Apps in education: widespread, simple, powerful, cheap

Some indications of the take-up of Google Apps and other cloud computing services in education.
  • "10 million Apps users in education" Oct 2010 [source]
  • "New York City, today [1/11/10] announced that it's moving to "Google Apps for Education," providing cloud-based email and collaboration tools to the entire university community. This announcement comes just weeks after New York State created an initiative to bring Google Apps for Education to their K-12 schools. With students and faculty across New York now using Google Apps, it looks like the Empire State has fully embraced the cloud." [Source]
  • In Australia, a struggle is underway for university cloud computing between Microsoft's Live@edu and Gmail. Many universities have switched, with Live@edu ahead at this stage. Gmail has 1.5 million student users in NSW DET schools. [source]
Universities and schools are finding that the predictions in the Horizon Report that 2010 - 11 is the time when 'cloud' computing will have a major impact, is being borne out. One factor is cost. Another is that the cloud systems come with lots of very appealing ancillary tools, like the ability to collaboratively edit files from any location.

The occasional voices of paranoia that used to be heard are being overtaken by a more realistic perspective. The fear that the FBI can monitor email under the US Patriot Act is one of these. Why schools should fear this is not clear to me. Australian intelligence agencies have similar powers, as they do over intercepting mail or tapping phones. Universities which deal with serious issues of intellectual property and research have apparently been satisfied that their data is appropriately secure. Why a police agency would target student online projects or the staff meeting minutes escapes me.

Real threats to student and staff security are much closer to home. The most real threats are much more mundane: careless forwarding of private information, insecure passwords, contacting strangers and bullying.

Why schools don't need ICT

This is the title of a provocative, brief and, I think, sound argument here by Ian Yorston about the failure of ICT to improve learning. He says we are smothering the digital revolution with rules.

In his own words:

"If you had to spend a million pounds, you'd really hope to have something to show for it."

"schools have finished up at the wrong end of the ICT revolution."

"...no money has been saved whatsoever...."

"Nor have we seen any obvious gains in productivity."

"The real curiosity is that, even when the newest, fastest, coolest computers have been purchased, heads promptly sit down to draw up policy statements that effectively cripple the machines before they have even been booted up."

"Now that we have finally built the Library of Alexandria — now that, thanks to Google, our students really do have access to all the world's knowledge in a curated and useful context, why would we want to limit their access?"

"We block Facebook and Twitter and YouTube. We denigrate Wikipedia and HowStuffWorks. We ban mobile phones and digicams. We even make our students write by hand."

"Schools don't need ICT. It's coming through our doors every day. We just need to adopt and adapt a little bit.


I think he is being a little ironic in his use of the word 'little' in the last sentence.



Computers in mathematics teaching = more math thinking

There is a very good TED talk (17min) below by Conrad Wolfram who makes a very powerful argument about how Maths teaching can be enhanced with the aid of computers. But it is very sad to read the initial comments on the TED site from the quite smart people who use TED. Most of didn't hear much of what he said. If you view the video you find that

Wolfram was at pains to say that Maths is about thinking mathematically, and its declining status in schools and broad aversion by many people is because the calculating (computation) part of Maths dominates what happens in schools and the other aspects are neglected. He says more attention should be spent engaging students with the three other aspects listed here. But the critics of changing the way things are done in the classroom often do not value the end point of learning. They think it is important for students to put in the hard work of learning how to calculate, remember, perform base level skills in the expectation that one day they will get a chance to apply these skills on real world problems.

For those interested in just one example of how this can work in practice, the Alice programming language is a wonderful tool to use from mid primary to advanced programming levels.

One-to-one backup salvation

A number of schools that are providing Apple notebooks for individual students are using automatic backups to make radical changes to how they manage one-to-one computing.

The students are provided with a backup hard drive that stays at home. They are required to use the Time Machine software to automatically backup the entire computer on a regular basis - possibly daily. Time Machine saves everything - settings, files, profiles etc. The Time Machine name comes from the fact that the hard drive saves each backup in series until it runs out of space. So a typical student may have 5 or 10 or more backups according to date. So if a computer is having problems, is lost or damaged, it (or a replacement) can be connected to Time Machine and restore to the latest or whichever backup version is desired. (If the problem appears to be caused by some new software, for example, go back to the backup prior to the software being installed). Everything is re-installed, so the only cost to the student is the hour or so that the restoration takes. There are backup systems available for PCs, so this is not just an Apple opportunity. The major issue here for a school is not technical but attitudinal.

The implications are very significant.

Maintenance: technical support demands can be reduced. Rather than tech staff needing to spend long hours trying to detect a claimed fault in a computer, the student can simply be advised to restore the problem computer from the backup. The storage and backup responsibilities of the school are greatly reduced.

Student Responsibility: The system places the student firmly in control of their own computer, just as they are currently responsible for their own paper based aids. This is highly desirable if students are to become responsible student and adult computer users. An important implication of this system is that students must have administration rights to their computer. Some schools find this threatening. Others, who have tried it, do not, because they prefer to deal with misbehaving students individually rather than constrain and limit what all students can to. A major benefit of this open approach is that a significant number of students will explore new software and potential of their computer, and pass this knowledge back to the school for the benefit of all. Parents who understand the procedures and responsibilities are generally very supportive.

The savings in unnecessary school computer administration are very significant.
