摘要

在解决数学问题时,如果能使用与心理表征相匹配的手势,幼儿的表现会更好。然而,尽管这种手势在教育环境中越来越普遍,却很少有研究探讨这种手势在触摸屏互动中的效果。因此,我们研究了在进行连续数列估算任务时,在触摸屏设备上拖动(使用与数字变化一致的连续手势)和点击(使用不一致的离散手势)对幼儿表现的影响。通过研究数字线估算的集合大小和位置差异,我们还能够探索一致手势优势效应的边界条件。我们采用了 2(手势类型:拖动或点击)×2(集合大小:集合 0-10 或集合 0-20)×2(位置:中点左侧或中点右侧)混合设计。我们共招募了 70 名 5 至 6 岁的儿童(33 名女孩),并将他们随机分配到拖动组或点击组。我们发现,在使用触摸屏时,一致手势(拖动)通常有助于提高成绩,但有边界条件。在完成难度较大的估算时(大集合中的右侧),拖动组比敲击组更准确,对刺激的反应更快,花费的操作时间更多。这些研究结果表明,当儿童需要明确的支架时,一致的触摸屏手势有助于释放心理资源进行策略调整,降低数字估算的难度,并支持构建心理表征。

Dragging but not tapping promotes preschoolers’ numerical estimating with touchscreens

When solving mathematical problems, young children will perform better when they can use gestures that match mental representations. However, despite their increasing prevalence in educational settings, few studies have explored this effect in touchscreen-based interactions. Thus, we investigated the impact on young children’s performance of dragging (where a continuous gesture is performed that is congruent with the change in number) and tapping (involving a discrete gesture that is incongruent) on a touchscreen device when engaged in a continuous number line estimation task. By examining differences in the set size and position of the number line estimation, we were also able to explore the boundary conditions for the superiority effect of congruent gestures. We used a 2 (Gesture Type: drag or tap) × 2 (Set Size: Set 0–10 or Set 0–20) × 2 (Position: left of midpoint or right of midpoint) mixed design. A total of 70 children aged 5 and 6 years (33 girls) were recruited and randomly assigned to either the Drag or Tap group. We found that the congruent gesture (drag) generally facilitated better performance with the touchscreen but with boundary conditions. When completing difficult estimations (right side in the large set size), the Drag group was more accurate, responded to the stimulus faster, and spent more time manipulating than the Tap group. These findings suggest that when children require explicit scaffolding, congruent touchscreen gestures help to release mental resources for strategic adjustments, decrease the difficulty of numerical estimation, and support constructing mental representations.
