以往关于学生证明能力的研究通常只探索一种形式(如口头或书面辩论)。本研究比较了八年级学生数学辩论的书面陈述和口头陈述,以确定这两种方式是否描述了相似的理解。我们使用不同的口头和书面论点的时间顺序和更大的样本量来复制Stylianides(2019)的分析。使用现有的证据评分方案,我们发现学生的书面和口头陈述的证据之间存在统计上的显著差异。学生们经常很难写出他们本来可以口头表达的论点,我们发现没有证据表明学生的书面论点比他们的口头论点更复杂。我们还分享了两个例证,反映了学生书面和口头辩论的差异。这项研究的结果表明,学生的证明能力可能并不像之前的研究所暗示的那样糟糕。
Previous research making claims about students’ proving capabilities usually only explored one modality (e.g. oral or written arguments). This study compares the written and oral representations of eighth-grade students’ mathematical arguments to determine whether the two modalities portray similar understandings. We replicate Stylianides’ (2019) analysis using a different temporal sequencing of oral and written arguments and a larger sample size. Using an existing proof scoring scheme, we found a statistically significant difference between students’ written and oral representations of proof. Students often struggled to write arguments they could otherwise represent orally, and we found no evidence that students’ written arguments were more sophisticated than their oral arguments. We also share two illustrative cases representing the disparity between students’ written and oral arguments. The findings of this study suggest that students’ proving capabilities might not be as dire as previous research implies.
