摘要

本研究旨在找出小学生在提出区域问题时的类比特征。在本研究中使用的方法是描述性定性使用案例研究方法。在区域问题的提交中,类比的特点可以分为三个方面:(1)相同的重新表述是在不改变问题本质的情况下重新安排问题结构中的元素。(2)同-异-重构是对初始问题中形式的某些元素进行修改和保持,使最终问题看起来略有不同。(3)异仿是对原问题中不存在的形状元素进行改变和添加,从而产生不同的问题。研究结果表明,学生最常见的特征是模仿,即产生的问题与最初给出的问题不同。因此,最常出现的不同模仿特征对应的是替代特征,即通过改变问题的背景,即改变蛋糕片的形状,在初始问题或源问题的基础上提出产品问题。

KARAKTERISTIK ANALOGI SISWA SEKOLAH DASAR DALAM PENGAJUAN MASALAH LUAS DAERAH
This study aims to identify the characteristics of elementary school students' analogies in proposing area problems. The method used in this research is descriptive qualitative using a case study approach. The characteristics of analogy in the submission of area problems can be categorized into three: (1) Identical-reformulation is rearranging the elements in the problem structure in ways that do not change the nature of the problem. (2) Identical-different-reconstruction is modifying and maintaining some elements of the form in the initial problem so that the resulting problem looks slightly different. (3) Different-imitation is changing and adding new shape elements that are not in the initial problem to produce a different problem. The results of the research showed that the characteristic most often found in students is imitation, where the problem produced is different from the initial problem given. So the different imitation characteristics that appear most often correspond to replacement characteristics, namely the problem posing product based on the initial problem or source problem by changing the context of the problem, namely changing the shape of the cake slice.
