摘要

数线被认为是理解分数的有效模型,但学生在解释数线上的分数时往往面临挑战。本研究通过调查学生在需要协调分数和数线知识的分数数线任务中的表现,为这一领域做出了贡献。为了探讨这个问题,我们开发了测试题目,122 名四年级学生参加了评估。对学生的书面答卷进行了三个阶段的分析:对学生整体表现的描述性概述、潜在特征分析以确定具有不同能力的亚组,以及对每个潜在特征的定性分析。研究结果表明,在所有任务中,学生的成绩都较低,这揭示了具有不同能力特征的三种不同的潜在特征:对数线上分数的直观理解、初步理解和高级理解。从这些发现中,我们推断出将数线作为分数模型的教学意义。

Profiles of young students’ understanding of fractions on number lines
Number lines are acknowledged as an effective model for understanding fractions, yet students often face challenges in interpreting fractions on number lines. This study contributes to the field by investigating students’ performance on fraction number line tasks that require the coordination of their fraction and number line knowledge. To explore this, test items were developed, and 122 fourth-grade students participated in the assessment. Students’ written responses underwent analysis in three phases: a descriptive overview of overall student performance, latent profile analysis to identify subgroups with different competencies, and a qualitative analysis of each latent profile. The findings indicated lower performance among students across the tasks, revealing three distinct latent profiles with different competency characteristics: intuitive, emergent, and advanced understanding of fractions on the number line. From these findings, instructional implications were extrapolated for using number lines as a model for fractions.
