The Selecting Search Activity has been rated 5 stars

RESOURCE OVERVIEW:

In this activity pupils learn about the basics of how search engines use web crawlers to index the world wide web (WWW). Pupils act like web crawlers themselves, indexing a very small portion of the WWW, and they then use this index to respond to search queries.

PUPIL OBJECTIVES:

  • I can explain how search engines select results.

TEACHING ASSESSMENT OPPORTUNITIES:

  • Informal teacher assessment of pupils during main task and plenary. Focus on key understanding of how a search engine’s select results, e.g:
    • Search engines have an index of the WWW. These are created by web crawlers.
    • Web crawlers move between web pages via links. They build up a search engine’s index by taking copies of the pages they visit.
    • When we make a search, a search engine looks up our keyword in its index to determine what pages to return in the results.
  • Assessment of pupils’ search engines’ indexes.
