ABACUS CALCULATION TYPE MENTAL ARITHMETIC LEARNING SUPPORT DEVICE ABACUS CALCULATION TYPE MENTAL ARITHMETIC LEARNING SUPPORT PROGRAM AND ABACUS CALCULATION TYPE MENTAL ARITHMETIC LEARNING SUPPORT METHOD

摘要

Provided is an abacus calculation type mental arithmetic learning support device etc. for supporting learning of abacus calculation type mental arithmetic by calculation exercises in which an abacus like screen is operated that is effective for strengthening the capacity for remembering positions of beads in addition to the capacity for operation of abacus beads and that is also suitable for measurement of capacity for abacus calculation type mental arithmetic. The constitution is such that an abacus like operating screen is output on a touch panel for a computer and calculation exercises similar to those of an abacus can be carried out by changing the state of beads on the basis of calculation rules for abacus calculations if the beads are selected by an operator. Display of changes in the state of the beads can be hidden in the calculation process and the computer is operated so as to display the state of beads after changes at a stage where a calculation completion operation has been received. In addition display of not only the changes in positions of the beads but also numbers forming answers at various stages in the calculation process is preferably hidden.
