ICT at key stage 3    (Year 7)

Unit 2: Information and presentation
Section 2: Activity 2

QCA

Objectives
Children should learn:
  • to use different methods for searching within sources
  • to find information using contents, indexes and key words and to use the results to modify a search strategy

Activities

Outcomes
Children:
  • Discuss the different type of search mechanisms provided on CD-ROMs and within internet sites, eg the hierarchical structure of a contents facility, site or content 'maps', key word searches, indexes, free-text and Boolean searches. Ask the pupils to define the questions they would like to answer through their research.
  • Ask the pupils to investigate their chosen sources and to use the different facilities to find suitable information to answer their questions.
  • While the pupils are searching their sources, discuss the approach they have adopted to refine free-text searches and how they can use alternative words to find relevant information. Ask them to continue to search for material from the chosen sources, for their project, saving useful pieces of text and graphics.
  • use a range of search mechanisms associated with sources and identify some of the advantages and disadvantages of the facilities
  • use AND or OR in their Boolean searches
  • modify searches after checking the relevance of material found

Points to note
  • Selection of resources is important to ensure a suitable range of search facilities is available for investigation. Web-based sources should be limited to preselected sites at this stage.
  • Pupils will need to question carefully what they find, before making an assumption about the success of their investigation.
  • Some pupils will need support when using Boolean search operators.
  • Homework could include an investigation of other ways of searching materials found in the home or library.
  • The activity could be extended to include using search engines to find further sources of information. Unit 10 'Information: reliability, validity and bias' addresses these techniques in greater detail.
