Gordin and Pea (1995) argued that some of the main advantages of the use of computers for instruction are the possibility to represent phenomena as a sequence of animation, adding a temporal component; the possibility to manipulate data sets, and to test the impact of the manipulation (Windschitl 1998), and increasing students’ motivation. Matray and Proulx (1995) claimed that animated software can illustrate and elucidate biological concepts more clearly and effectively than more traditional means—lecture, discussion or even conventional laboratory activities.
