Today I’d like students to spend time on data as IMAGES. Using my delicious, look at the video and internet resources (dated 22nd October) on pixels and bitmaps, rastor and vector images, and jpegs. Review the section from your textbook, (Mott, Leeming & Williams) pages 111-113. Here is a set of notes on data.
This week we’re moving to a new topic; Data and Information. We will
- Define data.
- State how data can arise.
- Study different forms of Data including text, still and moving images, numbers and sound.
- Discuss the need to code data on collection to enable effective processing.
- Explore the need to encode data on input to an ICT system.
The Teach-ICT website is a good place to start on this section.
We’ll round off this week by looking at and discussing some video material (BBC purchased clips) on ICT Systems and the Social Effects of ICT. We’ve been given the go ahead to visit shops and banks in central Wolves to see ICT as it is used in business and commerce every day. This short visit will precede the in-depth study we’ll be doing in Paris in February. I’ve included a short worksheet covering this section. Please complete it by Tuesday next week.
This week we’ll be looking at the following topics:
What is ICT? (The use of technology for the input, storage, processing and transfer of data and the output of information.)
What is a system? (Any system involves input, processing and output.)
What is an ICT system? (ICT systems are those where the output from the system goes directly to a human being or into another ICT system.)
Any ICT system is made up of components. The components are: • people • data • procedures • software • hardware • information. > Notes and an activity to summarise are available here.
As the online business world competition hots up, so too does the design of websites. Have a look at some of the latest examples showing what is current on the web for businesses. A variety of websites are shown every month on .net magazine in their showcase gallery. The websites also indicate how ICT has enabled scope for new business; music technicians, designers and graphic artists are doing well out of work on e-commerce sites.

We’re going to start off the lesson by booking a weekend trip to Paris. Using the websites: tripadvisor, lastminute.com, and flybe, we’re going to get the best flight deal and stay in a good hotel. The aim is to show how ICT has assisted people in getting the best, personalised holiday. Consider:
- Lastminute.com has a reputation of cheap last minute deals. Is this really the case? Look carefully at the times of the flights offered.
- Is there a ‘sting in the tail’ with flybe’s initial prices quoted on a flight? How many extras are added on by the time one gets to the check out?
- What makes a site like Tripadvisor useful? (Ratings of hotels, pictures, videos, reviews, forums.)
- Compare this experience to booking a holiday through a travel agent.
- What advantages and disadvantages are there for both of the above ways of booking a holiday?
Just a quick comment on your paragraphs on, “The consequences of the use of ICT for the aged and the disabled”; students must be aware that citing ‘teleworking‘ is not enough in your answer. Examples of how teleworking would be of assistance are necessary. e.g. It allows them to work at times of the day when they feel more productive and energetic, and to work from home without the worry of having to consider the difficulties of using public transport, or the high travel costs of commuting. Be aware that answers shouldn’t only consider the positive aspects – negatives should be considered as well. e.g. It might increase the risk of isolation for people who may already need more contact with peers and colleagues.
Here are notes on the cultural, economic, environmental, ethical, legal and social impact of ICT.
On Wednesday, students will do a task on e-commerce. This task will increase your understanding of online retail experiences, as well as enable you to see some of its advantages and disadvantages. Have a look at the two videos on my delicious which cover social_effects_ict_ecommerce as well. The fact sheet is due for completion and checking on Friday and the e-commerce task is due in on Monday.
P.S. Congratulations to Shoma! I’ve reproduced his factsheet, with a few tweaks, on ‘The Consequences of the use of ICT in Society’.
Work for Tuesday will be to complete a paragraph on “The consequences of the Use of ICT for the disabled and the aged”. This will count for a total of 8 marks. Email the document to me at the end of the lesson. Students must also begin to construct a fact sheet on the “Consequences of ICT for Society”. We’ll use the table from the previous lesson as an example. Students should cover ICT in: tourism, medicine, retailing, education, travel, communications and entertainment. Short video clips on social_effects_ are to be found by looking though my delicious tags. Watch the ones on medicine, they’re pretty good. The fact sheet task must be completed by Friday.
