Section Title Primary information Description and Notes Suggested resources
Lesson Length The expected lesson length will be approximately one hour

Some variation possible.

Assessment Level 1

 
Students The lesson is suitable for KS3 and KS4 students Since this is a new specification, the lesson is suitable for Year 7 to 9 students and differentiated by outcome  
Overall Focus This lesson will look at how search engines use logical operators and practise those elements

 

Lesson Links: 1, 2, 3, 4, 5, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39

Key words logic, statements, These words need to be reinforced throughout the series of lessons  
Assessment include AND, NOT and OR in information searches

Evidence here will be student's own work and assessor observations.

 
Key Questions Some questions to get learners thinking about the topics Some questions about how to improve the effectiveness and efficiency of searching for information. What techniques can we use with our understanding of logical operators to make search engines even more effective?
Learning Objectives
  • To understand logical operators in relation to search engines
  • To explore and explain the application of logic for search improvements
  • To understand how and when to use logical operators for efficiency

Students need to understand how and when to use the different types of logic and be able to explain with examples how they improve the way computers retrieve information.

If you are using the Learning Machine learning system, students can add their comments and material to this site as evidence of their growing understanding.  The site, if used consistently, will show progression via charts of activity and outcomes.
Teaching and Learning Elements
  • Teacher led discussion on information searches
  • Groups working on search techniques
  • Summarize the key findings

 

Mosaic browser icon

The above image was for the first real browser on computers called MOSAIC.  Things have changed on the Internet beyond recognition since this first appeared, but have the ways that searches work in browsers changed that much?

Information icon Compare and contrast the results from different browsers and then use logical operators to see how much refinement can be achieved.  Do they help, are they worth knowing, how can you evaluate their usefulness?

Lesson Structure Possible structure
  1. introduction to the history of the internet and searches
  2. discuss with students how searches work and why logic helps
  3. groups work on their own search logic to test
  4. check they can apply logic effectively
  5. write-up ideas
  6. intro to next session

Computer Hope logoThe above site has some useful tips on how to use search engines effectively, including some of the logical operators that can be deployed.

Try some of these tips and tricks on different search engines.  Is there a difference in the information found?  Do operators give the same results, regardless of search engine?  If so, why might that be?

Homework Come up with a search game for younger children to show them the power of logical operators. Students can vary their homework depending on their level of understanding Students can continue to document their experience on their portfolio system for assessment
