Résumé
This paper reports on an experiment investigating the effects of different kinds of computer-
based visualizations on the acquisition of problem-solving skills in the domain of
probability theory. Learners received either purely text-based worked examples, text plus
an instruction to mentally imagine the examples contents, or the possibility of retrieving
either static pictures or concrete animations that depicted the problem statement and the
problem states achieved by applying a specific solution-step. It could be shown that frequent
use of both static pictures and imagining the examples contents improved performance
on isomorphic problems. Frequent use of animations, in contrast, led to
substantial increases in learning time and a decrease in performance. Thus, the use of
concrete animations to visualize solution procedures was more harmful than helpful for
conveying problem-solving skills. Reasons for these outcomes are discussed in the light
of cognitive load theory.
