Today we live in a global community where individuals, schools and businesses want to communicate with other people all over the world quickly and easily.

(mouse click)Our first means of long distance communication was letter writing and telegrams. These forms of communication took time and meant that there was no possibility of direct long distance personal connection.

(mouse click)Then came telephones, a revolution in communication.

document.doc of 16



(mouse click)Then came the Internet. Communication via the Internet is instant and can be reciprocated in record time.

Since the invention of the Internet there have been many great advancements in how, when and where we can communicate.

Now that the Internet has become an integral part of our everyday lives, communication with other people has become easier and more convenient.

(mouse click)There are many ways to communicate online including email, instant messenger, chat rooms and, of course,

(mouse click)web conference.

With so many ways to communicate with people down the street or around the world, we are no longer separate communities or separate countries., and you all have a space within the digital world.

Web conferencing refers to a service that allows conferencing events to be shared with remote locations. In general the service is made possible by Internet technologies.

(mouse click)The service allows real-time point-to-point communications

(mouse click)as well as multicast communications from one sender to many receivers.

(mouse click)As well as video and voice chat you can also share communication via text-based messaging.

Activity: class – take part in discussion – My experience of…

Note to teacher: the aim of this short class discussion on their experience of web conferencing is to lead on to an activity of knowledge collection on: features of, use of, potential risks and keeping safe with web conferencing.What experience or applications of web conferencing have you been involved in?

Note to teacher: students’ experience will vary, therefore it is important to build upon their understanding from their starting point. If there is evidence of little

document.doc of 16



experience of web conferencing then it may be beneficial to set up a free or trial account to demonstrate. There is a free Skype service available at:

http://www.skype.com/intl/en-gb/home Webex offer a free basic account or 14 day trial of an advanced package

available at: http://signup.webex.co.uk/GB/buy/signup.html?TrackID=1021381)


Note to teacher: this slide is for you to collect the group’s thoughts. You can type / write straight into this whilst in presentation mode through a keyboard or Interactive White Board. Saving the PowerPoint will save the notes taken

Activity: class - contribute to knowledge collection (web conferencing features)

Note to teacher: ask the students to identify features of a web conferencing system. The following features are worth drawing attention to if not covered by the students.

Typical features of a web conference include: • Slide show presentations - where images are presented to the audience and

markup tools and a remote mouse pointer are used to engage the audience while the presenter discusses slide content

• Live or streaming video - where full motion webcam, digital video camera or multi-media files are pushed to the audience

• VoIP – real time audio communication through the computer via use of headphones and speakers

• Web tours - where URLs, data from forms, cookies, scripts and session data can be pushed to other participants enabling them to be pushed though web based logons, clicks, etc. This type of feature works well when demonstrating websites where users themselves can also participate

• Meeting recording - where presentation activity is recorded on the client side or server side for later viewing and/or distribution

• Whiteboard with annotation – allowing the presenter and/or attendees to highlight or mark items on the slide presentation. Or, simply make notes on a blank whiteboard

• Text chat - for live question and answer sessions, limited to the people document.doc of 16

http://www.skype.com/intl/en-gb/home



connected to the meeting. Text chat may be public (echoed to all participants) or private (between 2 participants)

• Polls and surveys – allows the presenter to conduct questions with multiple choice answers directed to the audience

• Screen sharing/desktop sharing/application sharing – where participants can view anything the presenter currently has shown on their screen. Some screen sharing applications allow for remote desktop control, allowing participants to manipulate the presenters screen, although this is not widely used



Activity: class – contribute to knowledge collection (use of web conferencing)

Note to teacher: ask the students to think about the features that have been identified of a web conferencing system, and ask them to consider the their uses e.g. the who, how, what

For an individual this technology enables you to keep in touch with all your loved ones. Phone calls are nice but over time they feel impersonal and distant. Live video and audio conferencing enables people to talk and carry on normal conversations. It provides a way for people to feel like they are in the same room and creates a way for the long distance relationship to feel less distant.

This technology is also a great way for school pupils to have interactions with other cultures. A teacher could arrange a video conference with a classroom of children from China, India, Japan, Russia, Australia or any other country in the world.Web conferencing is a great way to help businesses run more smoothly and effectively. Can you think of examples of businesses and organisations that might make use of it?

Note to teacher: possible examples:• Charity - non profit organisations• Professional services• Public sector• Retail• Financial services

document.doc of 16



• Healthcare• Manufacturing• Further and Higher Education

Web conferencing and online meetings offer a wide range of options for almost any business. How or for what do you think they would use the technology?

Note to teacher: possible examples:• Meetings• Training events• Lectures• short presentations• Hold a press conference• Demonstrate a product• Make a sales presentation• Conduct remote training• Collaborate on designs

Web conferencing offers a solution for anyone who wants to connect, collaborate, meet, or give presentations more effectively.



Activity: class - contribute to knowledge collection (risks of web conferencing)

This technology allows individuals, schools and businesses to stay in communication with the people or associates they find most important. It creates an environment where distance is no longer a problem, an environment where there is no distance, only good communication. As with all technologies there are associated risks - can you think of any in relation to web conferencing?

Note to teacher: the risks are pretty low and your students may not be able to think of any. The following risks are worth highlighting in light of the e-safety aspects that have recently been covered:

• There is a small risk of eavesdropping because VoIP works over public Internet connections. However, the risk is lower than that of using a conventional landline which can be easily snooped on

document.doc of 16



• If you are using VoIP for making calls between three or more people where the dialup and access details are pre-arranged, anybody who can access these details (for example by seeing the email) can also gain access to your call

• On systems such as Skype, fraudsters can request that you be their Skype

contact in order to:• Call or instant message you to conduct a scam or fraud, normally by

getting you to visit a fraudulent website or download a malicious file containing a virus or spyware

• Access personal details on your profile and use them dishonestly• Share files or direct you to websites containing inappropriate or

offensive content



Activity: class - contribute to knowledge collection (web conferencing – keeping safe)

Thinking about the risks, although fairly minimal, what would you suggest to Gump to help keep him and his friends safe when web conferencing?

Note to teacher: many of the e-safety aspects that have been covered should be drawn upon in relation to this. This is a good way to ensure the students are able to transfer the knowledge they are acquiring. Below are some examples to include in the discussion if not brought out by the students directly:Safe use of VoIP:

• Ensure you use strong passwords, and do not disclose them to anyone else

• If the service includes a public profile, don’t put any sensitive, private or confidential information in it

• When using systems like Skype, be wary about whom you accept contact requests from

• Set up your service to allow connections only from people you know

• Quickly block nuisance and fraudulent users from further contact with you and also report them for abuse

document.doc of 16



• Check regularly with the VoIP website for updates or patches

• Ensure you have effective and updated antivirus software

• Always log out of your VoIP service when you have finished your call. Simply closing the browser may not automatically finish the session

As we have discussed throughout the last few lessons, the Internet has had a profound effect on everybody's lives and its influence is increasing. No matter where you turn, people seem to be talking about

(mouse click)the cloud.

So what is cloud computing? Over the last few years clouds have become the buzzword in computing. But ask someone what cloud computing is and they’re likely to give you a very different answer to the person standing next to them.

Like clouds themselves, the definition of cloud computing is currently a little fuzzy.Cloud computing gets its name from the drawings typically used to describe the Internet. But what is a really simple explanation of what this ‘buzz’ word really means?

Activity: class – watch short video

Note to teacher: the image is hyperlinked to a short video of a humorous explanation (courtesy of Frank the dog!) The video explains the technology of ‘cloud’ computing in relation to storing a photograph of a dog - Frank. Image storage is probably something that students will be familiar with so this is a good starting point to explore more about web hosted storage and software application

Note to teacher: the use of drawings and narration being videoed is a quick and easy approach to presenting information. This approach could be encouraged for the students to use as part of the My Space User Guide on the wiki

Activity: class – take part in discussion on the wider uses of ‘cloud’ computing

Note to teacher: after watching the ‘Frank’ video (hyperlinked on the previous slide) ask the students about their experience of using ‘cloud’ computing. They may not be aware that they are actually using ‘cloud’ computing when they use Flickr, DropBox, etc. You may well need encourage and support them to draw out this information. This could be done initially by asking the students to consider the advantages of uploading images to online albums and allowing friends to access them rather than emailing them or placing them on a social networking site

Note to teacher: if you wish to explore more about personal cloud storage a good article for reference purposes is available at:

http://www.zdnet.com/blog/networking/the-six-best-personal-cloud-storage- choices-for-your-stuff/2198


You may think that the ‘cloud’ is just a technology solution to storing various types of data, but it has other benefits.

(mouse click)Today cloud computing covers anything that involves delivering hosted services over the Internet. These services are generally divided into three categories:

• Infrastructure-as-a-Service (IaaS)• Platform-as-a-Service (PaaS) and • Software-as-a-Service (SaaS)

Note to teacher: it is also important that students are made aware of the wider usage of ‘cloud’ computing within business, therefore below is additional reference information for you to draw upon to inform the students of the wider use in working practices.

• IaaS – As the name implies this is the infrastructure to run / execute your own software as it is needed. This is much like running a virtual server on your own equipment, except you are now running a virtual server on a virtual disk. This model is similar to a utility company model, as you pay for what you use. An example is Amazon Web Services at http://aws.amazon.com

• PaaS – In this model of cloud computing, the provider provides a platform for your use. In essence it is a way to rent hardware, operating systems, storage and network capacity over the Internet. The service delivery model allows the customer to rent virtualised servers and associated services for running existing applications or developing and testing new ones. Services provided by this model can also include website portals, or gateway software. An example of PaaS is GoogleApps.

• SaaS – This model is designed to provide everything and simply rent out the software to the user. The service is usually provided through some type of front end or web portal. While the end user is free to use the service from anywhere, there is a pay a per use fee. A few of the many offering this service are:• Salesforce (http://www.salesforce.com/uk/?ir=1)• 4Projects (http://www.4projects.com/)• Post my Files (http://www.postmyfiles.com/)

In today’s economy, companies are looking at any cost saving measures, and the bottom line is that cloud computing provides much greater flexibility than previous computing models.

The benefits of cloud computing are many. One is reduced cost for businesses, since they pay as they go. Other benefits are the portability of the applications: employees can work from home, work, or at other locations. This increased mobility means employees can access information anywhere they are.

The other side of the coin is the perspective of the commercial software producers. They have had to respond to the challenge of pricing with the advent of SaaS. Unlike

document.doc of 16

http://www.4projects.com/

http://www.salesforce.com/uk/?ir=1

http://aws.amazon.com/



traditional software which is conventionally sold as a perpetual license with an up-front cost and occasionally an optional on-going support fee, SaaS providers generally price applications using a subscription fee, most commonly a monthly fee or an annual fee. Consequently, the initial setup cost for SaaS is typically lower than the equivalent enterprise software for the individual or organisation but, there are obviously financial implications for the provider.

Potential extension activity: class debate

Note to teacher: consider further the theme of finances and ‘two sides to every story’ in the context of: open source versus closed source (proprietary) software. Advantages and disadvantages of each option with the main issues to the debate including cost, service and support, innovation, usability, and security, etc.


Clouds are owned by large companies. In the business world they are usually used by small to medium commercial businesses. These users normally pay the provider to use their computing resources.

As individuals we tend to choose the free cloud services, although some people get so used to using the cloud they then upgrade to a paid service.

All cloud services have three unique characteristics that distinguish them from traditional hosting:

• They are commercial and sold on demand to users.

• They are flexible - a user can have as little or as much of the service as they want at any time and can quickly outsource peaks of activity without long term commitment.

• They are fully managed by the cloud provider; the consumer requires only a computer and Internet access.

(mouse click)So if the name cloud computing came from the cloud symbol that is frequently used to represent the Internet in diagrams and all this data and applications are not in the sky, where are they?

Note to teacher: this could elicit a response but if not use it as a rhetorical question

document.doc of 16



(mouse click)The data and applications are stored in very large physical geographically distributed data centres, the locations of which are kept a closely guarded secret for security purposes.

(mouse click)Their distribution is global.

When you put your data into the cloud you’re handing it over to a provider who may have data centres in many different places, countries or even continents.While the great thing about the cloud is that you can access it from anywhere, the downside is you may never know exactly where your data is being stored.

This is bad news for people working with sensitive data such as health records, or governments wanting to store national records. If data is moved to a different country, a whole different set of legal rules could be in force. If you process data in the UK, store it on servers in the US and send it via France whose laws would you obey? Things can get messy very quickly.

Users can sign agreements with providers specifying which countries they would like data to be stored in, but as clouds are proprietary technologies it could be hard to check that this has been followed.

Governments and authorities are currently working on common laws to cover data. For example, in the EU, the Data Protection Directive requires data to either be stored in the European Economic Area (EEA) or in a territory that has equivalent legal privacy laws.

Note to teacher: ask the students to continue to work in their assigned groups for building the wiki pages. The activity of building the wiki will continue over a number of lessons, both in the class and as part of the students’ homework.

Your mission

(mouse click)To produce a guide to help Gump to become a ‘savvy’ user of his space in the digital world.

We have covered various features of web conferencing and web hosted data storage and software applications Activity: group – build a wikiYou should continue to populate the My Space User Guide (which you’re building in the wiki) in your assigned groups.

Remember to:• think about what you would like included in the wiki page – remember you

can include text, images and sound or video files• decide as a group who should be creating each element on the page – you

are working collaboratively• revisit some of the associated information that you have marked with ‘social

bookmarking’• read any blog that has been created on your page area

Note to teacher: explain that they will need to continue with this work as part of their homework so they need to agree how this will work as a group to ensure they all contribute and play an active part in this knowledge creation

document.doc of 16



Homework (30-60 min)


Homework:For your homework you should:(mouse click)

• continue your blog, covering the additional areas of ‘my space’ that have been covered

(mouse click)• read and feedback comments on

your ‘blog partner’s’ blog

(mouse click)• continue with the work you have

agreed with your group on the wiki

Note to teacher: ensure all the students are working collaboratively on the wiki build. Also that they all understand and know what the other members of the group expect from them

It is important that you continue to check that the students are stretching themselves in the knowledge creation and if they are appropriately displaying / communicating the knowledge to their given audience – new Year 7 student, Gump
