Abstract

We evaluate an educational system, "SoroTouch" developed for the acquisition of abacus based mental calculation skills efficiently. SoroTouch is an iPad app with a unique interface called "Invisible mode", where the beads are not displayed, and the student is required to visualize and operate the beads mentally to solve the problem. Furthermore, SoroTouch helps to train fast accurate management of the beads, while providing students with features to facilitate continuous learning. The analysis of user learning data revealed that in 2017 and 2018, 54% and 62% of withdrawing students successfully acquired mental calculation abilities by the time of their withdrawal, respectively. Time spent on SoroTouch for skill acquisition was verified to fall between 7 and 26 months. This time period is defined from the student's start of learning, until the student's demonstration of mental calculation abilities.
用隐形算盘评价心算教育体系
我们评估了一个教育系统,“SoroTouch”开发的基础上的算盘心算技能有效地获取。SoroTouch是一款iPad应用程序,它有一个独特的界面,叫做“隐形模式”,在这种模式下,珠子不会显示出来,学生需要在脑海中想象和操作珠子来解决问题。此外,SoroTouch有助于训练珠子的快速准确管理,同时为学生提供方便持续学习的功能。对用户学习数据的分析显示,2017年和2018年,分别有54%和62%的退学学生在退学时成功获得了心算能力。在SoroTouch上获得技能的时间在7到26个月之间。这个时间段定义为从学生开始学习到学生表现出心算能力为止。
