Abstract

Playful fraction picture books, together with math instructional content called “back matter,” may promote fraction learning, which is crucial because fractions are difficult and often disliked content. However, open questions remain regarding how different types of back matter may affect caregivers’ ability to use fraction picture books as a teaching tool. The current study offers a novel investigation into how back matter affects caregivers’ (N = 160) fraction understanding (i.e., equivalence and arithmetic) and subjective beliefs about math using a pretest/posttest design. We contrasted existing back matter text with research-informed back matter text crossed with either circle area or number line visual displays. Caregivers’ performance improved from pretest to posttest in the Researcher-Generated + Circles condition (fraction equivalence) and in the Existing + Circles, Researcher-Generated + Circles, and Researcher-Generated + Number Lines conditions (fraction arithmetic). In addition, caregivers were aware of their learning; they predicted improvements in their fraction arithmetic performance over time. These findings suggest that brief interventions, such as back matter in children’s picture books, may improve adults’ fraction understanding.

数线和圆圈视觉展示对保育员理解分数的影响。

寓教于乐的分数图画书，加上被称为 "背景材料 "的数学教学内容，可以促进分数的学习，这一点至关重要，因为分数是很难学习的内容，而且往往不喜欢。然而，关于不同类型的背景材料会如何影响照顾者使用分数图画书作为教学工具的能力，仍然存在未决问题。本研究采用前测/后测设计，对背景材料如何影响保育员（160 人）对分数的理解（即等价和算术）以及对数学的主观信念进行了新颖的调查。我们将现有的背景材料文字与经过研究的背景材料文字以及圆圈区域或数字线视觉显示进行了对比。在 "研究者生成+圆圈 "条件下（分数等量关系），以及在 "现有+圆圈"、"研究者生成+圆圈 "和 "研究者生成+数字线 "条件下（分数运算），照顾者的成绩在前测和后测之间都有所提高。此外，保育员也意识到了自己的学习情况；他们预测自己的分数运算成绩会随着时间的推移而提高。这些研究结果表明，简短的干预措施（如儿童图画书的背面内容）可以提高成人对分数的理解。
