Why and How?


Figuur 1: The principle of parallelism. The mean attention area: a working-, doing- or problem solving environment (A); the instruction, information or reference area (B); and the distance between them (x). The research question is: "What is the optimum of x?"


the dual-code theory (of Paivio, 1990)

the split-attention theory (of Chandler & Sweller, 1991)

the cognitive load theory (of Sweller, 1990 - 1994)

the multimedia learning theory (of Mayer, 1995)

the parallel instruction theory (of Min, 1992 - 1994)

Parallelism and 'virtual parallelism'

in a browser on a web-page:

Figuur 2: the surface of a web-page is bigger than the surface of the screen: so a web-page has a lot of virtual parallelism. That is a fantastic advantage compared with cd-rom and cd-i stuff
