Several studies have shown that the number line can be a useful tool to support early numeracy development. Here, we conducted a school-based training study to evaluate the effectiveness of the software "The Number Line" ("La Linea Dei Numeri"; Tressoldi and Peroni, 2013) in improving children's mathematical skills. We randomly allocated 10 classes of first, second and third graders (N=183) to one of three experimental groups: one group played with The Number Line; the second group played with Labyrinth, a computerized game designed to train attention skills; the third group had no intervention (business-as-usual). At the end of the first training phase, children in The Number Line group completed another training phase playing with Labyrinth, whereas the other two groups played with The Number Line. After playing with The Number Line, all groups displayed more accuracy when placing numbers in the number line task. However, we observed no evident improvement in other mathematical skills. These results suggest that specific training effects emerge even in the school context, although transfer to other numerical skills may be harder to achieve.
多项研究表明，数轴可以成为支持早期数学发展的有用工具。在这里，我们进行了一项基于学校的培训研究，以评估软件“数字线”（“La Linea Dei Numeri”；Tressoldi 和 Peroni，2013）在提高儿童数学技能方面的有效性。我们随机将 10 个一年级、二年级和三年级的班级（N=183）分配到三个实验组中的一个：一组玩数字线；第二组玩电脑游戏“迷宫”，旨在训练注意力技能；第三组没有干预（照常营业）。在第一阶段培训结束时，数字线组的孩子在玩完“迷宫”后完成了另一阶段的培训，而其他两组则玩数字线。在玩数字线后，所有组在将数字放置在线性任务中的准确性都有所提高。然而，我们没有观察到其他数学技能有明显的提高。这些结果表明，即使在学校环境中，也会出现特定的培训效果，尽管向其他数字技能的转移可能更难实现。
