Inclusion
How will you make your lesson inclusive?
|
Start with a class discussion about what learners already know. What computer systems do they know about and where are they used? Write ideas on the whiteboard and expand with more examples.
History of computing website: www.computerhistory.org/timeline/?category=cmptr
Show a video of computer systems from the early days to modern-day devices so that learners can see the difference e.g. in size, application of computer science and portability (History of computers video lasts about five minutes).

Ask learners to work in pairs to identify as many parts of a computer system that they can write up on board and then add to that list.
Develop this list into categories by brainstorming:
input devices (keyboard, mouse, touch screens, scanners, etc.)
processing devices (from large and power-hungry in supercomputers to small, low power consumption in smart phones and microcontrollers)
storage devices (internal memory (RAM), backing storage such as HDD and DVD, etc.)
output devices (printers, screens, plotters, etc.).

BBC Bite size contains notes, activities, tests, etc.: www.bbc.co.uk/schools/gcsebitesize/ict/system/0ictsystemsrev1.shtml
Teacher provides quiz or card sets, each set comprising the range of devices listed in the syllabus and their associated functions.
