摘要

这项研究的基础是中学生数学推理能力低下。学生在学习空间几何材料时遇到困难。这项研究的目的是了解高中生在几何空间问题上的数学推理能力。本研究方法是一种描述性的定性方法,通过分析学生对仪器的推理能力。本研究的工具以5个题目的笔试形式出现。根据YPI高中的研究结果,Palembang学生的数学推理能力平均为66.11分。总的来说,学生掌握的数学推理能力的一个重要指标是用图片和文字来呈现数学推理能力的一个指标,而学生掌握不足的数学推理能力的一个指标是从一个陈述中得出结论。这项研究是由低数学学生在数学方面的能力所激发的。学习太空几何材料的学生体验不同。这个研究可以描述高中学生在太空几何中的能力。本研究的方法是分析学生的理性能力。这个研究的工具是书面提出的五个问题。基于研究的结果在所有这些方面,由许多学生控制的数学意义的本质是用形象和写作来陈述数学陈述,而由学生策划而不被证实的行为的特征。

Analisis Kemampuan Penalaran Matematika Siswa SMA Pada Materi Geometri Ruang
Penelitian ini dilatarbelakangi oleh rendahnya kemampuan penalaran matematika siswa Sekolah Menengah Atas (SMA) dalam matematika. Siswa mengalami kesulitan dalam pembelajaran materi geometri ruang. Penelitian ini bertujuan untuk mengetahui gambaran kemampuan penalaran matematika siswa SMA pada materi geometri ruang. Metode penelitian ini adalah kualitatif deskriptif dengan menganalisis kemampuan penalaran siswa dari instrumen yang diberikan. Instrumen dalam penelitian ini berbentuk tes tertulis yang berjumlah 5 soal. Berdasarkan hasil penelitian penelitian di SMA YPI Tunas Bangsa Palembang diperoleh nilai rata-rata kemampuan penalaran matematika siswa sebesar 66,11 yang tergolong cukup. Secara keseluruhan, indikator kemampuan penalaran matematika yang banyak dikuasai siswa adalah menyajikan pernyataan matematika dengan gambar dan tulisan, sedangkan indikator kemampuan penalaran matematika yang kurang dikuasai siswa adalah menarik kesimpulan dari suatu pernyataan. This research is motivated by the low mathematical reasoning abilities of high school students in mathematics. Students experience difficulties in learning space geometry material. This study aims to describe the mathematical reasoning abilities of high school students in space geometry. The method of this research is descriptive qualitative by analyzing the students' reasoning abilities of the given instrument. The instruments in this study were in the form of written tests totaling 5 questions. Based on the results of research at Tunas Bangsa Palembang YPI High School, the average mathematical reasoning ability of students of 66.11 was obtained as an average. Overall, the indicator of mathematical reasoning abilities that are controlled by many students is presenting mathematical statements with images and writing, while indicators of mathematical reasoning abilities that are less mastered by students are drawing conclusions from a statement.
