Taking the Next Steps – the “Enhanced” Phase

This is the second in a series of articles that aim to help schooling systems develop their technology, the first being “Taking the First Steps“.

There are four distinct phases through which technology in schooling evolves. The first phase is characterized by access. In this phase, giving students and teachers access to computers to improve some aspects of lesson delivery and administration is the main focus. In the next phase, technology is used to enhance existing processes. It’s about providing content and tools to increase learning, organising communications and starting to manage data and information. The third phase is characterized by using technology strategically. No longer is technology considered a “bolt-on”, or “veneer” on top of existing processes – it now helps drive schooling towards strategic goals such as significantly improved learning and better return on investments. In the final phase, leading edge schools use ICT to transform their operations, using it to personalize learning, integrate deeply with the wider community, run extremely efficient administration systems and develop a culture of performance.

Four phases of ICT development in schooling

The “Enhanced” Phase

Goals

The goals of the Enhance Phase of ICT development are to:

  • Increase learning
  • Improve communications with parents
  • Manage data and information

Increasing Learning

In this phase, computers are available in several areas of the school, some in labs, and others scattered in classrooms and other learning spaces. These computers are connected together in a network and key resources, such as content, printers, scanners, and users are managed centrally.

Students use computers as a learning tool – e.g., using multimedia learning packages; solving maths problems; researching; reading from e-books; developing writing skills; learning languages; and developing 21st Century skills.

Curriculum Area Examples

Language
Hyperlinks allow more creativity in narrative construction
  • Word structure and spelling
    • A great example of how to help children remember how to spell individual words is the “Look Cover Write and Check” web application on the Ambleside School site   
  • Composing and presenting
  • Learning foreign languages
    • Bilingual audio books combine rich graphics with spoken word for foreign language learning. Award winning Mantra Lingua have combined traditional print media with a “talking pen”.    
Mathematics
Making visualisations easy in Mathematics
  • Learning from feedback
    • Word processing software now enables students to “word process” maths to clearly show complex formulae, along with 2d and 3d graphs, making it easier to communicate their thinking and get feedback on it. Check out the free Math add-in for Word and OneNote.
  • Creating patterns
    • Students can use Logo software to draw patterns students quickly learn the importance of expressing their commands unambiguously and in the correct order
  •  Seeing connections
    • A software Graphing Calculator can be a great tool for teaching maths when used with a data projector for whole class teaching, or better still when given to students to use.  A lesson can be built up and stored then each stage “replayed”. Check out the free Microsoft Math 4.0 
  • Exploring data
    • Students can design surveys, such as the heights of their peers and teachers, and enter the data into a spreadsheet to learn about averages and correlations.
Science
 
  • Assisting observation
    • Electronic telescopes enable pupils to collect images from different locations on Earth and at different times of the day. Telescope sites also provide learning resources and galleries of images.  
  • Recording and measuring
    • USB microscopes and data loggers can be used in the classroom to observe, record results, plot graphs and analyse data. E.g. see this data logging programme from Kent which explores topics such as: most effective sunglasses; which surface will slow down the car? Who has the hottest hands; where is the noisiest place in school?
  • Providing models or demonstrations
    • Simulating experiments can enable students to experiment with phenomena that may be too slow, too fast, too dangerous or too expensive to experience in school. Check out Crocodile Clips’ Yenka for example.

An essential consideration is accessibility for all. For students with some disabilities, technology can open up new windows of learning opportunities. For a full explanation go to: http://edutechassociates.net/2011/03/08/accessibility/

A fantastic resource exploring different ways in which ICT can be used across the curriculum can be found here: http://archive.naace.co.uk/direct2u/indexbysubject.html

Additionally, worksheets with practical examples and screenshots explaining how to use ICT in Primary Schools are available here

Other resources developed for classroom use by teachers, for teachers can be found in the Teachers Toolbox and here.   

Managing Learning Content

When ICT is implemented, lots of content gets created.  In order to get maximum efficiencies from ICT, this content needs to be organised and managed in a way that means that people don’t replicate one another’s work.

At school level, content can be managed through a file sharing system on a server on a network. For example, Windows Server 2008 enables files to be centrally shared and managed. The “Shared Folders” feature enables file-shares to be created and permissions set, which will allow students and teachers to store their work.

At a more advanced level, content can be better managed using a portal such as SharePoint Server 2010. Combining content management with collaboration tools and powerful search, SharePoint makes information easy to find, share, and use.

Beyond the school, regions or even whole countries are beginning to provide organised learning content, as explored in the articles on SULINET and managing learning content.

In Brazil, for example, Educopedia is a learning content portal run by the City of Rio. Users are presented with a list of all of the elementary and middle school grades and under each of these they can access all the school curricula for each discipline.

Educopedia - learning content access made easy

For example, a teacher can click on a subject area link, and see a content index consisting of the school year course plan which contains the lessons and related curriculum standards.

Educopedia - making it easy to select resources related to curriculum standards

From there, they can download lesson plans with suggestions on how to make the best use of the resource materials available; a list of the skills and competences addressed; a PowerPoint presentation for classroom use; and a quiz with questions about the class content.

Educopedia - access to learning tools made easy

Educopedia also provides users with communication and collaboration functions through live@edu, which provides a mechanism for user authentication.

Parent Connection

The usual way in which schools communicate directly with parents is via “parent evenings” – many parents end up seeing a teacher once or twice a year for 5 minutes. Hardly enough time to say “hello” and “goodbye”. 

Research demonstrates that active parental involvement in educational activities delivers a positive impact on attainment. Technology can be used to connect parents with information regarding the educational progress of their child, and a range of supplemental activities in which the parent can support the learning process. For example, ICT can be used to:

  • Enable parents and teachers to communicate more frequently with each other
  • Identify problems and issues at an early stage and involve parents in rectifying them
  • Give parents the tools to support learning activities at home
  • Provide parents with immediate news about the school and its activities.

At a basic level, ICT can contribute:

  • E-mail news bulletins
  • Digital learning resources to assist the student with homework
  • Educational resources for parents, such as behavioural management guidance
  • Alerts on critical issues such as lack of attendance, dropping attainment levels, behavioural issues, etc

Managing Data and Information

Teacher Administrative Tasks

ICT can really help with reducing the time spent on teacher’s basic administrative tasks including:

  • Lesson plans and materials
  • Producing class lists
  • Keeping and filing records
  • Analyses of attendance and results
  • Writing reports
  • Ordering supplies and equipment.
  • Producing formal minutes of meetings
  • Submitting bids 

In Latvia, the Ministry of Education were able to achieve time savings of 30% by deploying SharePoint Server across 100 schools. This allowed them to automate routine grading tasks and reporting, delivering significant time savings for teachers.

Managing Baseline Administrative Data and Information

Whilst different countries have different mandatory requirements for essential data that they expect schools provide, UNESCO (2003) has set out a recommended specification of essential data to collect at the national level from each education establishment.

Data on students Data on teachers and other categories of personnel
Distribution by grade, gender and age Distribution of teachers by level of qualification and certification, by grade and by gender
Distribution of repeaters by gender and grade Distribution of teachers by age and by gender
Number of learners attending double-shift classes by grade. Number of teachers working double shifts
Data on education establishments Number of teachers in multi-grade classes
Number of classrooms Number of non-teaching personnel by categories, age and gender.
Places available in schools Distribution of teachers by level of qualification and certification, by grade and by gender
Education expenditures Distribution of teachers by age and by gender
The budget as part of the overall State budget (budget voted and budget disbursed) broken down by level Number of teachers working double shifts
The expenditures at the local level, of private organizations by level Number of teachers in multi-grade classes

Student Information Systems (SIS)

Schools need to keep records on their students which should, at the very least, include: 

  • Personal – name; address; photo; family contacts
  • Performance – actual and predicted grades; teachers comments
  • Attendance – by day, by lesson, over time
  • Risk profile – learning, social, medical and demographic
  • Intervention history – what assistance and guidance has been given to the student
  • Timetable

Scenarios

Student Access

Providing students with their own laptops for use at home has proven learning impact

A study by the UK Institute of Fiscal Studies in 2009, shows that “learners who use a computer at home for schoolwork could get as much as ½ a grade to their General Certificate of Secondary Education (GCSE) examination results and as much as a term on to their GCSE learning”. No surprise then to see the explosion of national level projects for the wide-scale introduction of ‘personal learning devices’. However, many of these schemes wrongly focus on a ‘blanket’ approach of providing huge numbers of cheap portable PC’s. Unfortunately most of these projects have been driven by getting the most computers for the lowest price, rather than focusing on getting the right device for the learning that needs to be done.

To get the best return on investment a device for students should have the following features:

  • Provide a platform for use of the widest range of productivity, creativity, and communication and collaboration tools
  • Result in users acquiring relevant knowledge and employability skills  
  • Have a display of around 13 to 15 inches
  • Have software that makes learning accessible to all, including those with disabilities
  • Capable of being managed remotely and as part of a managed network
  • Sharable with other users  
  • Battery life should exceed 3 hours under full CPU load with full screen brightness
  • Appropriate ports to allow them to connect to other equipment
  • ·Wireless networking capability
  • Be self-contained and work without needing high levels of internet access once set up
  • Protected from viruses, spyware, and other malicious software
  • Hard Drive encryption for security

One of the advantages of giving students a PC – as opposed to lower specification devices – is that they can share them with family and friends, amplifying the effects of the investment. For example, Mouse Mischief enables students to share applications extending the use of the device.

Classroom

Ideally, students will be able to bring their laptops into the school and make use of them within a managed network, but this takes time, so a more likely scenario in the Enhanced phase is that students use shared computer resources at school. In this phase, there is likely to be an ICT suite with enough computers to take at least 30 children sharing a computer in pairs. Computers will also be found in other learning spaces in the school to support the kind of learning scenarios mentioned above. The computers that were originally used in the school can now be distributed throughout the school, some of which can be used as Thin Clients networked to the Server and/or Windows Multipoint Server.

Of course, computers aren’t the only hardware devices used in the classroom. Digital cameras; video cameras; voting devices; interactive whiteboard tools; robotic kits; digital microscopes; and projectors all have a role to play in the learning process in the Enhanced phase.

School

With ICT across the school, there is need for an organised network to manage ICT services. Learning content, devices, peripherals, access, administrative processes and users. Connecting with a local authority, state or national level learning content service is crucial, and this has to take place within a secured environment. The school will also need to connect to secure Local Authority services within a Wide Area Network.

An important question in this phase is how to manage e-mail. This can be done “on-premises” using server software such as Exchange Server; as a ‘rented’ service such as Exchange Online; or as a free “commodity” type service such as Office 365 for Education. The answer depends on the amount of resource available to manage the service, and the degree of control that a school wants to have over e-mail policy. Increasingly email – along with services such as calendaring and personal file storage – are commodity services that institutions are happy to see moving into the Cloud.

School managed network conceptual design

 Another useful document that considers the full range of devices that a school in the Enhanced phase could use is the Computer Sustainability Toolkit.

Local Authority – MoE

With a system in place for collecting baseline administrative data, there now needs to be a continuous flow of information between schools, the Local Authority and Ministry of Education with budget allocations flowing downwards and reporting on performance flowing upwards. This has to be achieved through a Wide Area Network to ensure the secure transfer of data. Several technologies are available for this including “Leased Line”, “Circuit Switching”, “Packet Switching” and “Virtual Private Networks”.

Wide Area Network between school and "upstream" authorities

As we saw above, the Local Education Authority of Rio City also provides learning content and collaboration services to schools. These can be delivered as a web service from a data centre.

Technical Requirements

The foundation on which the entire schooling architecture is built is called “Optimised Infrastructure”. This provides a scalable, secure platform which can be built on to provide a growing number of services.

Key capabilities of an Optimised Infrastructure are:

Security

The key component without which none of this will work is stringent security and networking protocols. This is needed to protect students and employees from unauthorised users, viruses and unsuitable content. Security systems should automatically identify threats and respond automatically.

Local Area Network (LAN)

Computers need to be connected to a LAN – wired and/or wireless – with a server that controls the network, stores files and enables printing. A classroom might have just a few computers that all the students take turns using, so it’s important that an educational computer be configured just the way the teacher wants.  The teacher shouldn’t have to waste valuable teaching time troubleshooting.  Each PC in a LAN needs to be “locked down” and reset easily. 

Data Protection and Recovery

As ICT becomes increasingly “mission critical”, it’s important to manage data so it can be rapidly recovered.  When infrastructure is fully optimised, recovering information should be as simple as browsing the network. Backup devices are now very cheap to buy and manage, and will automatically run in the background.

Identity and Access management

Identity and Access Management can help organisations centrally manage user information and access rights. It allows administrators to manage each student, teacher, administrator individually by setting their role, access and functional level.  This enables individual users to have information and software tools that are specific to their individual requirements – a personalised IT service.  A directory service holds each user account and its access functions and allows the user to access various systems using the same set of credentials. Authentication can be by various mechanisms such as logon credentials, smartcards, and biometrics.

Desktop, Server and Device management

In an optimised infrastructure, those responsible for the management of networks have the tools to control their IT infrastructure; easing operations; reducing troubleshooting time; controlling quota; password re-setting; provisioning users; improving planning capabilities; and managing mobile devices.   

Integration and Interoperability

A key goal of optimising infrastructure is to integrate different systems so they can exchange data. The advantage of this is that data only has to be inputted once, and then used by multiple systems saving time and money.  Ideally data in Student Information Systems, Teacher Administration and Accounting Packages will interoperate, saving teachers and administration staff from having to re-key in data every time they wanted to update records or produce reports. 

Database Services

Databases are the “engines” of information management. They are used to capture, store, analyse and interpret a wide variety of information, and deliver this information to a range of different applications and devices including servers, desktops and mobile systems. Data includes text, numbers, pictures, video streams, audio content, and geo-spatial information. Not only do databases store data but they interpret, index and enable it to be searched.  

Technical Support

Schooling system networks need to be reliable to encourage user confidence and to support learning and teaching, as well as school management and administration.  This requires access to technical support, which can come from technicians within the school, or from another provider, or sometimes from students themselves. In an optimised infrastructure, schooling systems need to move away from a reactive system in which incidents are dealt with only as they arise. Instead they need to create a more pro-active system where technical support prevents problems occurring and ensures that individual ICT systems are robust and reliable and available when required.

Architecture

Bringing all this together the overall architectural model for a school in the “Enhanced” phase looks like this:  

Schooling Technical Architecture - essential building blocks

Conclusion

It’s often harder to take the second step than the first. Indeed, moving from PCs in a single location to an integrated and managed network has many challenges. The advantages well outweigh the challenges because by developing the school’s technology in this way, students gain access to a wider range of learning opportunities, develop more skills and knowledge. Teachers can use ICT to engage better with students and their parents, and school administration can improve enabling more effective use of resources.

In the next article in this series, we will explore the next phase – moving from using ICT to enhance existing operations to using ICT to drive strategic change.   

Learning Analytics, Los Angeles, July 11-15th

On July 15th , I’m chairing a roundtable discussion on Learning Analytics at the Microsoft Worldwide Parnter Confernece in Los Angeles. I’ll be working with my good friend Chris Poole from lookred, and we’ll be focussing on:

  • Examples of how analytics can be used to drive effective learning and efficient operations at schooling system, municipality, state and national levels
  • Real examples of solutions making impacts in schools
  • How to use data, BI and management tools to improve quality and reduce costs
  • Engagement with education customers – how to focus on their challenges rather than just the technology
  • “Why BI in education”. BI is at the heart of not only modernising schooling but saving money in doing so
  • What does a data driven model of education look like to the key stakeholders

The context for the discussion will be:

  • The urgent need to modernise education
  • Growing pressure to ‘do more with less’ and be more accountable
  • The need to make informed decisions in the same way a business might do so
  • The need for tools to support greater productivity from teachers
  • Tools used to engage students

If you are a Microsoft partner attending WPC, you might find this roundtable worthwhile. I’m certainly looking forward to participating.

Chris and I will be available for the full week of 11th – 15th July to meet with people who are interested in this topic.

Cloud Watching #2 – How to Manage 30Bn Trees Worth of Data

Data is fundamental to operating schooling systems. Without data schooling systems would grind to a halt – teachers wouldn’t get paid; students wouldn’t get transported; taught and fed; and essential services would cease to operate.

As the value of good data for decision making is becoming more widely understood, the quantity of data in the world’s schooling systems is ballooning. But how much data are we talking about, how fast is it growing, and how can it be better managed.

To get a sense of how big the issue is, let’s start by looking at Charlotte Mecklenburg in the US – a School District that has paid a lot of attention to its data and information systems recently. According to David Fitzgerald, Vice President of the Education Group at Mariner, Charlotte Mecklenburg School District in the US plans to use 70 Terabytes for a system with 140,000 students – 524.3MB per student.

The US and Western Europe account for ~10% of the world’s school students population – 0.12Bn. So, assuming similar levels of consumption across these regions, we can estimate that in these areas alone there is 60,000TB of data in schooling systems. 1TB = 50k trees worth of paper and print, so we’re looking at 3bn trees worth of data. Imagine that every student on the planet used the same amount of data as Charlotte Mecklenburg – that would add up to 30bn trees.

Whilst it’s currently unlikely that the amount of data in schooling systems adds up to this amount yet, there are several factors pushing it hard in this direction.

For example, major countries such as Russia, Mexico and Brazil are developing and running massive student data operations, increasing both the quantities and sophistication of data used.

UNESCO (2003) state that most countries develop education databases, and they also specify the optimal datasets that should be maintained. Let’s suppose that this adds up to a minimum of 1/2 a typewritten page on each of the student population living outside the USA and Western Europe, roughly 1 Kilobytes each. Rounding-off, we can estimate that 1bn students x 1Kb = 954GB. It’s interesting to think that this could be kept on a single external hard drive no bigger than a paperback book. However, add other data, say a single low-resolution image per student, and that rises by a factor of 8. Add digital work produced by students and this number grows exponentially.  

Also, there is a sharp increase in the rate at which data is used in developed countries. Take New South Wales for example. Last year, New South Wales Department of Education and Training – which has 1.3m students – used 280TB of storage space – but this has been doubling every year for last five years!

The amount of data used in schooling can only increase as governments around the world recognise that it is core to improving effectiveness.

WHY IS MANAGING DATA CORE TO IMPROVING SCHOOLING EFFECTIVENESS?

Driven by the need for better accountability for how public funds are spent, and the widespread use of international benchmarks such as PISA, there is a sharp increase in the number of governments and private companies that are investing in solutions for data driven decision making. These investments aim to use data to:

  • Improve student performance: Give students, parents, teachers and administrators a clear picture of student performance at an individual or group level so they can adjust and personalise learning accordingly
  • Make better management decisions: Inform routine decisions and strategic planning across all enablers and disciplines with accurate, readily-available data
  • Increase accountability: Quickly and easily understand performance across organisations
  • Manage resources more effectively: Gain a better understanding of projected revenues and expenditures; keep track of financial health; compare costs against those of other organisations
  • Drive administrative efficiencies: Improve time and effort taken to report information. Improve quality and presentation of information.

SO WE HAVE TO TALK ABOUT DATABASES THEN?

Why is it that peoples’ eyes glaze over when you start talking about databases? Most web pages that you will experience – including this one – are driven by databases. For most people databases are “black boxes”, and few care about how they work or what they do. However, a basic understanding of databases and how they work is essential to understanding how ICT can make schooling more effective – so let’s take a quick database 101:

WHAT IS A DATABASE?

Databases arrange data as sets of records, and these records are arranged as rows. Each record consists of several fields which are arranged in columns. The rows and columns combine to form a table.

 

Most large scale databases are Relational, which means that they can connect data from two or more tables.

  • Forms are a main way to enter data into a database
  • Queries are used to get data out of a database.
  • Reports format and display data from the database.

Indexes improve the speed of data retrieval operations by querying a unique key which in turn uniquely identifies each row in a table. Metadata – data about data – can include tables of all tables, their names, sizes and number of rows in each table; or tables of columns, what tables they are used in, and the type of data stored in each column.

DATABASE ESSENTIALS

At the heart of a database is the Database Engine – software for storing, processing and securing data; providing controlled access and processing capabilities. The structure of the database is described in a Schema, and this is usually written in a language called “Structured Query Language” SQL. This language determines how data is inserted, queried, updated and deleted. Different database vendors have different extension to SQL – T-SQL is Microsoft’s extension to SQL.  

A Data Warehouse is a database that extracts data from operational systems for reporting. It can aggregate data from different sources, and ensure that the integrity of operational data isn’t compromised by the processes associated with analysing it.

Integration Services are the means by which data from various sources can be integrated, extracted, transformed, and loaded into data warehouses.

OLAP – or Online Analytical Processing – enables data to be manipulated and analysed from multiple perspectives. Eg a Longitudinal analysis could involve the study of student progress over time, and take advantage of an OLAP Cube to interrogate a number of different dimensions over a given period.

 

Analysis Services supports OLAP by allowing the design, creation, and management of multidimensional structures that contain data aggregated from a range of data sources, such as relational databases.

Data Mining – is about extracting patterns from large sets of data, to yield Business Intelligence (BI) for example, high achievement correlated with the number of books in the family home, or low reading ability impacting examination results. Data Mining Services enables the design, creation, and visualisation of data mining models.

Reporting Services – enabling reports to be published in various formats drawing on content from a variety of data sources. They also centrally manage security and subscriptions. Portal Integration – it’s crucial to for end-users to work with operational data – in ‘dashboard’ format ideally – through a portal site.

 

To be able to manage databases is crucial and several key tools are used for this. Master Data Services is the means by which all applications across the organization can rely on a central, accurate source of information.  Replication – copying and distributing data and database objects from one database to another, and synchronizing between databases to maintain consistency. Automated compression and backup are also key tools.

WHAT HAS THIS GOT TO DO WITH THE CLOUD?

With massive growth in the amount of data used in schooling comes questions about sustainability, cost and management. The Cloud offers some major advantages here:

1. Ubiquity

Having data in the cloud makes it easier for authorized users with internet access to access that data from almost anywhere.

2. Management

In an enterprise architecture where resources are distributed, organisations usually have a single SQL Server back-end with WAN links and/or multiple distributed SQL Server installations that replicate data with each other. Maintaining this kind of environment is time consuming and expensive. With the cloud, replication, backup, compression etc are all taken care of.

3. Pricing

As with other Cloud services, you only pay for what you use. During the peaks and troughs of schooling system operations, one can expect to see varying amounts of data storage requirements.

SQL AZURE

SQL Azure is Microsoft’s Cloud Database solution, and it offers the following benefits:

  • No physical administration required – software installation and patching is included, as SQL Azure is a platform as a service (PAAS)
  • High availability and fault tolerance are built in
  • Simple provisioning and deployment of multiple databases
  • Scale databases up or down based on business needs
  • Multitenant – i.e. a single database can provide services to multiple organisations
  • Integration with SQL Server and tooling including Visual Studio®
  • Support for T-SQL-based familiar relational database model
  • Option for pay-as-you-go pricing

The SQL Azure suit currently comprises of the following offerings, some currently on limited availability:

SQL Azure Database – a Platform as a Service (PaaS) relational database. Highly available and scalable .

SQL Azure Data Sync – allows organisations to extend their current sets of data into the Cloud. It provides synchronisation between an organisation’s current SQL on-premises databases and SQL Azure Databases in the Cloud.  Currently available in Community Technology Preview.

SQL Azure Reporting – a complete reporting infrastructure that enables users to see reports with visualizations such as maps, charts, gauges, sparklines etc. Currently available in Community Technology Preview. 

The Windows Azure Platform Appliance under limited trials, this will eventually enable organisations to deploy their own Cloud Services from within their own datacentres. The Windows Azure Platform Appliance consists of Windows Azure, SQL Azure and a Microsoft-specified configuration of network, storage and server hardware.

TAKING ADVANTAGE OF CLOUD DATABASE SERVICES

Taking full advantage of the Cloud is not something that is going to happen overnight. Besides careful analysis and planning for migrating existing services, Cloud computing opens up a whole set of questions around what new services could be offered. For example, the rise of virtual schooling across the world – as brilliantly analyzed in the US by Clayton Christensen in his book “Disrupting Class” – will be a major beneficiary of cheap, ubiquitous database services at massive scale.  

As pointed out in the Cloud Watching #1, moving to the Cloud is not without effort and risk. David Chappell, in his excellent paper “The Benefits and Risks of Cloud Platforms: A Guide for Business Leaders“ points out that storing data outside their organization makes people nervous. Many countries have regulations about where certain kinds of data can and can’t be stored, so before putting data into the Cloud platform, it’s important to ensure compliance.

A key question is to ask whether any given data centre is more secure than those of the major Cloud service providers. A significant data breach for a Cloud services provider is likely to mean a huge financial loss, so there’s a very strong incentive for them to keep the data they hold secure.

David Chappell also advises – “as with any new technology, starting small can be a good approach. Perhaps your first cloud application should be important, for instance, but not truly mission critical”. The same can be said for data.

CONCLUSION

Whilst its early days for Cloud based database services in Education, we’re beginning to see interest turning to into plans and action. For example, Curtin University in Perth, Australia, has started to move some of its services to the Cloud and intend to take advantage of SQL Azure. 

Educause Horizon Report 2010, includes an analysis of Cloud amongst other key and emerging technologies – http://wp.nmc.org/horizon2010/chapters/trends/ It states:

“The abundance of resources and relationships made easily accessible via the Internet is increasingly challenging us to revisit our roles as educators in sense-making, coaching, and credentialing”.

Cloud will no doubt change how data is gathered, manipulated and interrogated, and by making vast amounts of storage available at extremely low prices we can look forward to seeing innovative organisations build completely new services to reach growing numbers of learners in completely new ways.
