Effects of Calcularis Training | Part 2: Changes in Psychosocial Characteristics (Effekte des Calcularis-Trainings | Teil 2: Veränderungen psychosozialer Merkmale)

Effects of Calcularis Training | Part 1: Domain-Specific Changes (Effekte des Calcularis-Trainings | Teil 1: Domänen-spezifische Veränderungen)
This publication looked at the direct, longer-term effects of Calcularis. The children who participated in the study trained for 20 minutes five days per week over a period of six to eight weeks. It was concluded that Calcularis doesn’t simply lead to an improvement in the short term, but also enables learners to build on their progress over a longer period.
