abstract     : This article presents the design and a first pilot evaluation of the computer-based training program Calcularis for children with developmental dyscalculia (DD) or difficulties in
learningmathematics. The program has been designed according to insights on the typical
and atypical development of mathematical abilities. The learning process is supported
through multimodal cues, which encode different properties of numbers. To offer optimal
learning conditions, a user model completes the program and allows flexible adaptation
to a child’s individual learning and knowledge profile. 32 children with difficulties in
learning mathematics completed the 6–12-weeks computer training. The children played
the game for 20 min per day for 5 days a week. The training effects were evaluated
using neuropsychological tests. Generally, children benefited significantly from the training
regarding number representation and arithmetic operations. Furthermore, children liked to
play with the program and reported that the training improved their mathematical abilities.
