It is common for classes to make special arrangements so that individuals and/or groups can have access to computers. 

Such arrangements include

• scheduling groups to ICT on particular days to ensure equity of access
• sequencing students to use the computers as the preceding students complete their tasks
• sending off groups to resource teachers or aides (when the resource teacher or aide is available)
• placing students with visitors as the opportunity arises, eg, parents or senior students are available to assist

Consider the following in-class situation...

While the class does aerobics...

'William' has his turn on the computer!!

    The prime reasons for special arrangements include

• access to limited ICT resources (eg, only 2 or 3 computers)
• access to support 
• a desire to maximise students experience of using and operating ICT (typically 2-4% of class time for most students)
• not enough opportunities (occasions)

Thus the use of ICT can place children 'outside the class' and often does and is disruptive to their participation in the class program.
