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 The focus for this session will be to go over some of the techniques used to improve searches, such as the use of wildcards This lesson will look at some additional techniques to help with better searching

Lesson Links: 1, 2, 3, 4, 5, 6, 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 algorithm, search, sort, logic, efficiency, effectiveness, Internet, search engine, value, wildcards These words need to be reinforced throughout the series of lessons  
Assessment

use search techniques to improve efficiency of finding information

Evidence here will be student's own work and assessor observations  
Key Questions Some questions to get learners thinking about the topics Students need to show that they can use additional search techniques to improve their activities What is a wildcard?  How does it help your searching?  What ways an you use wildcards?  Where can you use wildcards?  What other techniques can you use?
Learning Objectives
  • To understand and show the way searches can be refined with " " and wildcards.
  • To describe and explain, with examples how searches are modified and improved
  • To practise as a class some techniques to be effective searchers and assessors of content

Students need to apply their understanding of the Internet to practise and write about what they understand, particularly in relation to using search modifiers.

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
  • More examples of how searching can be modified
  • Students can break into groups and work on exploring the aspects of searching
  • Class discussion and examples of their findings
  • Group or individual work on developing their own work

Searching for the information you need can be improved by using search techniques.  If you are looking for specific files on the network you can use file wildcards and the file extension you need, for example *.mpg to find all videos. On the Internet, the use of inverted commas helps to restrict what you are looking for, such as "internet search engines"

Use some of the student's ideas and examples to flesh out a solid understanding before progressing

Question students about how and why they did what they did.  Check for understanding.

Students need to start thinking about Information compared to data.  How can we determine value when applied to data?  How do students evaluate the data or information they find.

Can they show what algorithms might be used in the searches that they design?

Lesson Structure Possible structure an existing one.
  1. introduce some of the key ways that searches are modified and why
  2. take a detailed look at search engine modifiers and look at the impact
  3. group work to work on some of their own ideas
  4. discuss what they have learned and what they can apply
  5. volunteers to share their work and explain how they came to their opinions
  6. highlight next week's focus and issue homework

As previously, there is also lots of good examples on the BBC logo bitesize pages.

GoogleYahoo!Ask.comForestle and Bing are popular search-engine websites. Some older services include WebcrawlerLycos, and Alta Vista.

There are various sites which list search improvement techniques, such as this one.

Homework Get students to write a list of their 5 favourite software applications. Students can vary their homework depending on their level of understanding Get students to document their experience on their portfolio system for assessment
