MARKING SCHEME

ICT AS/Advanced
SUMMER 2008

INTRODUCTION The marking schemes which follow were those used by WJEC for the Summer 2008 examination in GCE ICT. They were finalised after detailed discussion at examiners' conferences by all the examiners involved in the assessment. The conferences were held shortly after the papers were taken so that reference could be made to the full range of candidates' responses, with photocopied scripts forming the basis of discussion. The aim of the conferences was to ensure that the marking schemes were interpreted and applied in the same way by all examiners. It is hoped that this information will be of assistance to centres but it is recognised at the same time that, without the benefit of participation in the examiners' conferences, teachers may have different views on certain matters of detail or interpretation. WJEC regrets that it cannot enter into any discussion or correspondence about these marking schemes.

ICT UNIT 1
1. Information consists of processed data or data with a context. Knowledge is derived from information by applying rules to it. Appropriate example covering both parts. For example, information could be 1.03, 1.07, 1.15 minutes, time in a swimming race. Knowledge would be that the swimmer with the time of 1.03 has won because the rule is that the person who completes the swim in the shortest time is the winner. Two other costs: time human resources Appropriate example, such as: the time consuming nature and the specialist staff requirements Accept also, time to re-train (could come under time or HR issues) time to analyse the data 1 1 2

Two appropriate examples (one for each) such as: (complete) An address on a letter without a postcode will delay delivery. An incomplete order may result in non delivery of some items. (up to date) Letters sent to deceased people causing great heartache. Accurate data is correct/ truthful/ has no errors 1 mark for clear explanation of the difference It would pass any range or format checks but it would not be accurate 1 mark for specific example Example: a customer completes a form with DOB which is correct e.g. 12/10/84 A data entry clerk makes a transcription error and types in the numbers the wrong way around 10/12/84 A good example clearly showing the differences is worth two marks Any two of (written in a sentence) (just 2 factors named - 1 mark) Correctly targeted, e.g. if asking for information about motorbikes there is no point asking car drivers. Understandable, e.g. if the information is in a very complicated format then it will waste time and people could draw the wrong conclusions from it. Relevant, there is no point using information about babies from people whose children are in their late teens. Accept, but not condone:Timely if applies to one of the points above Reliable if it relates to the source of information 1 mark for process 1 mark for example NOT aiding the decision making process Process: Monitor progress Example: Information obtained by market research and sales figures can help achieve this. Process: Can target reasoning and strategy making Example: Buy more of a certain commodity because sales are good. Advertising and marketing a product should be aimed at people likely to buy it otherwise it is a waste of time. Process: Gain advantage over competitors Example: Information can identify gaps in a particular market which can then, on the basis of sound information be filled. Process: Spot trends Example: Analyse sales data and realise when something is out of fashion e.g. sales of tape recorders or if one region buys more of something than another.
