In this unit pupils investigate the large-scale use of data by commercial organisations. The unit is based around the use of ICT in the retail industry and pupils find out about electronic stock control systems, including the use of bar codes and electronic point of sale (EPOS) systems, and loyalty cards. The social implications of loyalty cards and EPOS cards are emphasised.
The unit also introduces pupils to the ways in which other organisations collect data, the Data Protection Act, and the different ways data can be protected from misuse or damage.
This unit involves extensive class discussion and will need to be managed so it gives pupils the chance to deduce answers from the facts presented. It can be taught without direct contact with computers, although the use of the internet is encouraged.
Although many of the activities are based around the retail industry other contexts could be used.
This unit is expected to take approximately 3 hours.
