  • Take a stab at what this is?
  • Here are some scenarios……imagine if you will that you live in this place…….
  • Or this place…….
  • Or this place……and you dreamed of a better life. You dreamed of water. You dreamed of fish…..and you dreamed of getting them together in your new vocation as an aquaculturalist – just like Peter.
  • Peter is an aquaculture lecturer at Urrbrae TAFE
  • This is the kind of work that Peter does. He manages fish tanks, and in particular, he manages this one, which houses Guido the Silver Perch. By the way, this is what it actually does look like in an aquaculture tank.
  • And this is what Guido will look like when he grows up. Right now Guido is only just a mere fingerling – the size of….well…the size of a finger.
  • And imagine a bit further if you will….imagine you are this guy who also dreams of a different life – a life where the water runs clean
  • Like it does at this place…..most of the time. But all of these environments need active management to keep them healthy and functioning well.
  • We have the facilities to do this.
  • Toilets reuse rain water.
  • Urrbrae campus + geo-locating.
  • Remote students.
  • Foot print in the sky. Networks external to tafe.
  • Tools and services.
  • There has been a lot of buzz about the term “cloud computing” in recent months. The reality is that it has been around since the 1960’s and it takes its name from the “cloud” shape that is often used to depict the internet.   The cloud is basically a bank of computers networked together. It can be hundreds of small computers, or a couple of bigger ones. The cloud is the internet, and it equates to data and applications being stored on the internet as opposed to on your personal computer. When you need to do some work, you connect to the internet to access your data and software.
  • AUDIENCE PARTICIPATION Pros Less outlay for hosting, soft ware, hardware. Improved performance – if your website suddenly gets a spike in visitors the cloud will allocate more space allowing your website to grow or shrink to match demand which negates overloading or heavy traffic issues. Lower maintenance costs – as the IT experts manage the tricky bits. Instant software updates – available for free next time you log on. Accessibility – internet connection provides access to everything – you could be up a mountain yet still access your data. Greater mobility of work force. Less expensive – as it is cheaper to create space for backing up data on the cloud on virtual servers. Better collaboration – allows for joint access and editing rights to the same version of the document – no more worry about what is the latest version. Only pay for what is used – don’t pay for services and space that you don’t use. Security issues addressed through access to quicker upgrades and patches which is managed by professionals – there will be nothing to “infect” on the personal computer New Computers- If computers no longer need to store their own software and data, this makes way for a new light weight, less expensive computer.   Cons   Who owns the data? Because cloud computing does not allow users to physically possess their data (the exception being the possibility that data can be backed up to a USB or CD) it does leave responsibility of data storage in the hands of the provider. Dependence on a remote service provider who can lock your data down, unless you build your own bubble (thus, The London Times newspaper compares cloud computing to centralized systems of the 1950s and 60s, by which users connect through "dumb" terminals to mainframe computers). Security - users sacrifice their privacy and personal data to a third party Internet connection – what about a global power failure?
  • An educational mashup occurs when data is collected from two or more sources and reused (or repurposed) for education. This approach is not new, and occurs commonly in artistic fields such as music, art, video – or even in my grandma’s kitchen when she wants to create new and exciting ways with vegetables!  
  • Data blogging is the ability to blog about something in a structured way – so the data in the blog can be tracked and used in mashups. Most data blogs include geo-blogging which records location.
  • And that is exactly what we are doing in the Guido project – grabbing data from a range of sources, mixing it up and presenting it in a new format. We believe the educational experience will be more meaningful as the learning content is presented to students in an engaging and interactive manner in a do or die project. If the students don’t take it seriously – fish could die! There is a real sense of urgency and realism in this e-learning project.
  • This is a flow diagram how the system work. If we start up at the top with Data Collection – this data is then blogged and stored in the cloud. On the way into the cloud, the data can be checked for extremes or errors and an automatically generated message will be sent to the team if any action is required. Students can collaborate and problem solve by using a range of networking tools (eg twitter, sms, forum, online chat). One option is that data from the cloud can be mashed up and sent to Moodle where learning content for the relevant units is already stored. So students use the real time data from Guido’s tank along with the learning content to make decisions about how the tank will be managed. Students then collaborate to make decisions about what to do. Each student submits their recommendations back to their lecturer Peter Preece, and Peter collates student responses, assesses them and provides feedback and takes action if required. The cycle can then start again – which could be daily, weekly, or involve other forms of data collection. What is happening is that the students are actively involved with the day to day management of Guido – even if they are 000’s of km away.
  • Stop new nukes – an educational project which aims to raise awareness about the impact of nuclear weapons and utilises Google maps and Flickr to locate, depict and describe nuclear disasters that have occurred in the past.   Job market maps - which uses Google maps and data from various employment agencies to visually display where job vacancies occur in real time, sorted by sector and salary range and location.   Uni of Minnesota - MIIM project focussing on teaching geography and GIS through simulations and easy tools (not the full version of expensive software, but a “come and try version”.   Uni Massachusetts - teaching cultural history by marking up Google Maps and integrating historical and current knowledge.   Harvard University - investigating a social mashup with the class timetables and Facebook friends integrated so that the students can more easily weave their social desires in with study needs.
