5 Ss now exchange information orally and complete all sections of the notes. Make sure Ss do not simply show each other their notes. Ask them to suggest questions for each part of the note-taking frame or use the questions suggested in the book.

Instructions/complex instructions
GPASS is a program used by UK general practitioners. Ask the class to read the instructions for finding specific patients so that they can tell you how to do this. Elicit and note on the board simple numbered instructions:
Click on the appropriate tab.
Enter the search criteria.
Select the Defaults button.
Click on the Find button.
Then ask questions firstly to elicit explanations. Use the explanation to make the instructions on the board more complex. For example, Why click on the appropriate tab?
To find patients. Click on the appropriate tab to find patients.
Illustrate the other structures in the same way. Note that if the explanation is put first in the instruction, it should be followed by a comma. For example, To find patients, click on the appropriate tab.
Explain that the word order depends on what information you wish to make important. Putting the explanation first emphasises the explanation.
Finally, show how the numbers can be replaced by sequence words and how sequence can also be shown by Having doneX, and Once X has been done as in the book examples.
6 and 7 Do these individually, then compare in pairs. As a follow-up, you can ask Ss to write instructions for any computing activity they are familiar with. The best test of instructions is for others to attempt to follow them. If you can set this up using a computer lab, this can lead to a very lively lesson with each group preparing instructions for others to follow to the letter. Weaknesses in production and comprehension are soon shown up if the planned outcome from following the instructions is not achieved.

9 This is an information exchange activity. The texts may be a little difficult as they are in informal journalistic style. However, this is common in computer magazines and these form an important means for students and professionals to keep up with the subject. If Ss evince an interest in computer games, which account for large sales of software, as follow-up you could ask them to find out the top five games for the class.
