在珠算教学过程中,一个较为突出的问题是学生的指法常常出错,三指配合不协调。这在一定程度上与长期以来使用毛算盘作教具有关。因为在毛算盘上拨珠不便,常常使教师本身“三指分工”不落实,示范作用受到限制。此外,使用毛算盘作教具在教学上还有诸多不便。 In the process of abacus teaching, one of the more prominent problems is that students’ fingerings often make mistakes and the three fingers cooperate with each other in an uncoordinated manner. To a certain extent, this is related to the long history of using abacus as a teaching aid. Because of the inconvenience of dialing beads on the wool abacus, teachers are often not allowed to implement the “three-finger division of labor” and the role of demonstration is limited. In addition, the use of gross abacus as a teaching aids in teaching there are still many inconveniences.
