Images
Jump to:
Images can be used in a great many ways and they are very easy to source. Cheap digital cameras, built in cameras in phones, Google imagesTM, interactive whiteboard images and screenshots clipped from a computer screen all offer quick and simple ways to provide images. However easy it is to source an image then to use it effectively in teaching and learning is a different matter.
The accessibility of an image depends on technical factors (colourless, contrast, sharpness) as well as pedagogical factors (how effectively it is labelled, how well it is described, how it is integrated into a text / audio narrative).
With a little time and practice you will soon be able to effectively use images in an imaginative way to the benefit all users.
