Choosing keywords for searches
Situation: You are writing an article about teaching,
where you want to find information about what sorts of principles should govern how teachers give feedback in the classroom.
What keywords will you use?

Principles for choosing keywords
Where set phrases are generally accepted, use them
If you get too many returns, add more keywords
Play with different ways of expressing the same concept
![Page 11: Effective search techniques](https://reader036.fdocuments.net/reader036/viewer/2022062310/56815cc0550346895dcac51f/html5/thumbnails/11.jpg)
Advanced searching
If you get too many hits, restrict your search using Advanced Search
If you get too many hits focusing on one irrelevant topic, restrict your search by deleting that irrelevant topic

Dealing with results 1
Don’t automatically click on the first result Read through the summaries Look at the URLs (especially domains) You may need to look through the first 3 or
4 pages of results
![Page 25: Effective search techniques](https://reader036.fdocuments.net/reader036/viewer/2022062310/56815cc0550346895dcac51f/html5/thumbnails/25.jpg)
Dealing with results 2
When you have lots of possible relevant websites, use the right mouse button to “Open in new window”
Keep an eye on the taskbar at the bottom of the screen (or the tabs at the top of the screen)
Work through the pages you have selected after finishing with Google
![Page 26: Effective search techniques](https://reader036.fdocuments.net/reader036/viewer/2022062310/56815cc0550346895dcac51f/html5/thumbnails/26.jpg)
An example of dealing with results
You want to find 10 examples of funny headlines to put in the lifts (or to give to Ajarn Harvey to put in the lifts)
You search for: “amusing headlines”

Searching for pictures
Using Google, choose ‘Images’ Use the same searching strategies as when sea
rching for information With results, left-clicking allows you to see th

Finding background information
For a topic where you would like to gain a general overview, searching can produce results that are too specific
Use an alternative, such as Wikipedia: http://en.wikipedia.org/wiki/Main_Page
![Page 38: Effective search techniques](https://reader036.fdocuments.net/reader036/viewer/2022062310/56815cc0550346895dcac51f/html5/thumbnails/38.jpg)

Task
Think of some piece of information you would like to know (don’t make it too straightforward)
Will you use a search engine or a directory? What keywords/phrases will you use? Will you use advanced searching? How will you deal with the results? TRY IT!
