Introduction
We live in an information rich society. Today, many work roles are dependent on the ability to access and retrieve data to answer a query, gain a performance overview or analyse trends over time. In preparing our children to become economically active in the society of the future, we need to provide opportunities to handle data to support research in a variety of curriculum contexts. Teaching in ICT must develop the understanding, skills and strategies that pupils need to retrieve relevant, accurate, unbiased information from electronic sources. Pupils need to understand the advantages of storing, searching, sorting and displaying
electronic data in electronic formats. They need to appreciate the limitations imposed by poor database design, and the risks presented by inaccurate, biased data.
Data handling, is essentially a sorting and classifying activity, appears in various guises throughout the primary school:
The nursery class child sorting Compare Bears into sets according to colour or size for example
The reception class child may use PB Bear to sort the birthday presents according to the shape of the package
and the Year 6 pupil using a key to identify a rock pool animal, are all examples of sorting and classifying activities which are undertaken across the primary range both at and away from the computer
.At Key Stage 2, pupils are learning what questions they can ask and which tools to use to find answers. They are beginning to develop the process skills of enquiry: they can plan and carry out an investigation, knowing that they can only ask about the data stored in the file, shaping their questions around the record/field structure. They can predict likely outcomes, and use their prediction to check the validity of results. It is vitally important that pupils develop a good understanding of the link between naturally-expressed questions and appropriate retrieval tools. If we ask “Which was the hottest day?” do pupils know that the quickest way to find out is to sort the ‘temperature’ column, with highest first?
