The Use and Capture of Images for Computer-Based Learning II - Section 1:

"Alesandrini (1984) in a survey of American commercial educational courseware found a low rate of use of graphics. There may be several reasons for this: a low level of understanding of the use of pictures among designers; designers may see graphics as an added extra and not central to the design and learning process; overemphasis on the word as the primary vehicle of information; resources of suitable images in computer useable form may be unavailable or have copyright restrictions or in the case of computer-based courseware graphic displays may not have been capable of achieving the results needed.
