USB Microscope

There are many different types of cameras on the market, and a fair few USB cameras out there.

At Gloucestershire College we have just invested in some new USB cameras, however these are not standard USB cameras, these are USB Microscope cameras.

Install the software, connect the USB microscope and then place whatever you need under it. Once in focus and or zoomed in you can then take an image or capture a video.

You also have the possibility of a live preview, therefore showing what is happening live under the microscope through a data projector, even to an interactive whiteboard.

This is an eyebrow.

There are many uses for this in various curriculum areas.

The obvious choice is Biology to look at biological specimens under the microscope.

Hairdressing and Beauty Therapy have many uses for looking at hair and skin in much more detail.

Computing can stick the microscope into a PC or over a circuit board to see it in more detail.

Engineering can use it to look at issues with components or engine parts.

There are a wealth of uses, what would you use it for?

To block or not to block

Very often in education it is decided that the best way to “protect” learners is to block as much of the internet as possible. This is more often than not the policy in schools, nearly just as much in Further Education, and even in Universities.

I have for many years that technological solutions such as blocking are a blinkered approach to e-safety and that educating and training learners in how to use the internet safely and to be aware of the issues relating to digital identify was a much better and superior answer. If you block and lock down the internet, it can result in a false sense of security, this could result in learners not been fully protected.

It would appear that this viewpoint has been echoed in a recent Ofsted report on e-safety.

There was this interesting article from BBC News on this report:

Pupils given a greater degree of freedom to surf the internet at school are less vulnerable to online dangers in the long-term, inspectors say.

“Managed” online systems were more successful than “locked” ones at safeguarding pupils’ safety, they said.

The article continues…

The five schools judged outstanding for online safety all used managed systems to help pupils become responsible users of technology.

So what was the difference?

…while the 13 schools using locked down systems kept pupils safe while in school, these systems were less effective in helping them learn how to use technology safely.

Now this is interesting. You decide that the best way to protect learners is to lock down your system, the end result is that they are less protected.

One of the key reasons that this happens is that as the teachers and management perceive that the network is locked down and thus safe, they don’t need to worry about informing the learners about e-safety and digital identity. Of course once that learner goes home to their unlocked home internet, their smartphone, their 3G dongle, a friend’s computer… they have no concept of how to act responsibly and safely online and as a result put themselves at risk.

I would suspect that those schools that lock down their systems, have no real idea themselves about the issues and potential dangers of the internet for their learners; and feel that their responsibility only lies with their own computers… let the children fend for themselves outside school….

Whereas those schools which manage their systems, allow learners greater freedoms, have a much better awareness of e-safety and have ensured that it is part of the curriculum or tutorial programme.

If your institution is serious about e-safety and safeguarding, it will know that technological solutions are in fact not solutions at all, merely simple aids in supporting a coherent, robust practical strategy and policy based on education and training.

So what type of institution is yours?

Who helps your learners “become responsible users of technology”?

Screenr

I’ve realised that I have not mentioned Screenr before except as one of my top ten web tools that didn’t quite make the top ten!

So what is Screenr?

It’s a web service that allows you to make screencasts quickly and easily, then have them posted to the web.

Once on the web, you can either share the URL, put it in an e-mail for example, or on Twitter.

You can embed the video into a webpage on a website or on a VLE. This is in the Flash format. What about if you have a smartphone or an iPhone, well Screenr ensures that the video is available in an MP4 format which will play on the iPhone, other smartphones and internet capable video devices.

Screenr also allows you to share your video on YouTube.

Finally one useful aspect is that you can download the video as an MP4 file. This can then be embedded into a PowerPoint presentation. You can also import this video file into iMovie and edit it, add titles, other video, to create a new video. If you have the appropriate MP4 codec on your Windows PC you can import it into Windows Movie Maker and do something similar.

What I like about Screenr over other similar tools (like Jing) is that it doesn’t require you to download an application or install anything. Go to the website, click create screencast and then everything is simple after that.

For example this video on the new Mac eBook Reader software was created using Screenr.

One note though is that the service works basically with a Twitter account. You don’t need to use the Twitter account, but just thought I would point it out.

NVIDIA Tablet Chipset

NVIDIA made a major announcement on Thursday introducing their latest Tegra 2 mobile chipset.

The Tegra 2 chipset incorporates 8 independent processors to handle web browsing, HD video encoding/decoding as well as mobile gaming. It also accomplishes all this with a very low power consumption. In part, this is accomplished by the use of the ARM Cortex A9 dual core processor. The ARM Cortex A9 is the same processor that has been rumored to be utilized in Apple’s future tablet.

NVIDIA’s Tegra 2 powered Tablets boasts the following features:

– Over 16 hours of HD video or 140 hours of music on a single charge
– Adobe Flash Player 10.1
– 10x faster than processors used in smartphones today
– Playback 1080p video

The TabletNetBook is Alive!

Last week on this blog I posted a blog entry about how the Netbook is Dead.

This week is CES and a few things that have been announced have (in my opinion) helped to reinforce that blog post.

Leonovo have announced their “netbook”. The ThinkPad X100e is an 11.6-inch notebook that starts at a consumer-friendly price of $449. Hardly a cheap micro-laptop? Whilst Samsung have announced a range of netbooks, all models offer the standard 10.1″ LED backlit display. Hardly the small netbook form factor that the Asus EeePC fermented as the netbook form factor? These are not netbooks, they are cheap laptops. Welcome as they are they are hardly revolutionary!

Then on Engadget we see this.

So what is it?

It’s a tabletnetbook or as they call it a smartbook.

Freescale Semiconductor is helping to kick this year’s CES off with a bang, as its latest reference smartbook design actually has somewhat of a sexy flair to it. Currently, the model is little more than a great idea, but the company is hoping to have it available for partner evaluation starting next month. In theory, at least, this “smartbook tablet” would boast an ultrathin form factor, weigh around 0.8 pounds and get powered by a 1GHz i.MX515 processor. Other specs would include 512MB of DDR2 RAM, a 1,024 x 600 touch panel, 4GB to 64GB of internal storage, a microSD expansion slot, optional 3G WWAN module, 802.11b/g/n WiFi, Bluetooth 2.1, GPS, a USB 2.0 socket, audio in / out, 3 megapixel camera, inbuilt 3-axis accelerometer, an ambient light sensor and a 1,900mAh battery. We aren’t quite sure what kind of bulk discounts Freescale is counting on, but it’s hoping that this design will “enable a second generation of smartbook products with prices less than $200.”

For less than $200 (which in tech currency conversion means less that £200) this could be a device to certainly give all those e-Book Readers a run for their money, but also is a potential netbook replacement.

Effecting change

So it’s day two of Ascilite 2009.

I walked slightly late into the opening session, which was a presentation from Blackboard (who are the Premier Sponsor of Ascilite 2009). Despite chuckling at a few things that the presenter said (there is no way whatsoever that Blackboard can be described as an open platform). There were some interesting developments from Blackboard on how they are integrating Web 2.0 services into Blackboard. Those of you who have read my recent posts on the VLE is Dead debate will know that I wrote then that the VLE can be a tool to enhance and enrich learning and be a portal to a world of Web 2.0 tools and services. Now when I wrote this I was in the main referring to Moodle, the open source VLE. It would appear that either customers have been asking, or that Blackboard is fearful of the open VLE or Web 2.0 and are now making their product more open to plugging in services and tools that are available on the Web.

After that we had the ever excellent Professor Gráinne Conole, who delivered her keynote, entitled: Pushing the boundaries into the unknown, trajectories of user behaviour in new frontiers.

I enjoyed her presentation, and I was also attempting to live blog her keynote on Cloudworks; not sure if I made a success of that. Live blogging is an art, and not one I think I have mastered yet. Maybe it’s because I am more of a reflective person. This blog article for example is been written at 6.30pm, quite a few hours after Gráinne delivered her keynote.

Cloudworks is really starting to grow on me as a collective tool. The resources on the VLE is Dead debate for example have made it much easier to direct people to the superb collection of blog articles on the subject. Gráinne’s overview of the site and the ways in which it can be used was very illuminating.

After Gráinne came Peter Mellow who very cleverly used the two projectors to deliver two linked presentations. Though first we were all made to stand up.

He made some really interesting points on how we have been doing exactly the same thing for the last two thousand years in education…

Over the rest of the day I attended a variety of sessions, some good, some excellent and some, well some not so good.

Tonight is the conference dinner in the SkyTower, should be fun and a great chance to discuss and continue the conversation.

Small interventions, fundamental shifts

This morning I was at one of the Symposia at Ascilite 2009, Cascading Change: The role of social software and social media in educational intervention and transformation.

In recent years social media and social software tools and practices have been applied in numerous implementation and pilot studies in higher. Some have been driven by explicit educational goals, while others seem to have been inspired by the attractive, technical flexibility of an emerging decentralized landscape of loosely-coupled, networked tools and services and its alleged potential for changing the dominant patterns of institutional provision of ICT in education. This symposium brings together a diverse and international group of researchers to explore the problems and limitations of using social media as a leverage point for second-order change in higher education. It aims to engage contributors and the audience in theoretical and empirical reflection on possible directions for further conceptual and methodological development in that area.

This was an interesting debate and as is usually the case there wasn’t sufficient time for a lot of discussion. I was hoping with the Twitterfall screen up that we could have an online debate, however Twitter decided to have a big fail. Ah well.

One of the questions that came up was why with all these “interventions” why is change so slow or not happening.

My opinion is that these changes or interventions we make that we report at these conferences are always small and tiny and therefore can’t make a huge differences. We need to make major interventions at a institutional or even at a societal level if we are to effect fundamental change.

I also wonder if the culture of how we work is also a barrier to systematic change. In HE especially with a focus on research and publication, there is less incentive to effect change and more incentive to carry on researching and attending conferences and getting papers published.

People with the power to effect change do not (in the main) attend such conferences and therefore such changes do not happen at an institutional level.

Of course change does happen at an institutional level, but often with administrative systems rather than teaching and learning. For example does your institution use e-mail or MIS ?

As with the MIT OpenCourseWare and other similar initiatives in this area we can see that sometimes there can be fundamental shifts in the ways institutions work.

So how do we move things along…

Ascilite Day #1

So here we are with the official start of the Ascilite 2009 Conference. As I write this it’s late Monday morning in Auckland, but late Sunday evening back home in the UK. It feels weird blogging and tweeting about the conference, whilst people I know back in the UK are getting ready to go to sleep.

With a traditional Māori welcome we then launched into the traditional conference openings from the great and the good.

The first keynote of the conference was form Dr Scott Diener of the University of Auckland. He is an advocate of Second Life and described how he saw how Second Life was going to change education. He was very passionate about Second Life and its use in education. He demonstrated his island live to the audience.

Now I have talked about Second Life before and as you may know I don’t really “get it”.

I either seem to be the technology luddite with the red flag walking in front of the Second Life car, or maybe Second Life is not this life changing and social changing technology that many think it is.

Now it may be just me, for example I can see some real potential and benefits of Augmented Reality technologies, but don’t see similar opportunities with Second Life.

Of course this doesn’t mean I am right, but what do you think?
