Abstract

Literasi spasial merupakan komponen penting yang harus dikuasai siswa. Literasi spasial mendukung pemahaman siswa tentang geometri ruang yang erat kaitannya dengan dunia nyata. Namun, fakta di lapangan menunjukkan bahwa kemampuan literasi spasial siswa rendah. Oleh sebab itu, penelitian ini menyelidiki fenomena literasi spasial siswa pada pemecahan masalah geometri ruang. Desain penelitian ini menggunakan pendekatan kualitatif. Peneliti memberikan soal literasi spasial kepada 5 siswa kelas XII SMA dan meminta siswa menyelesaikannya. Kemudian, wawancara dilakukan kepada setiap siswa secara individu. Pada artikel ini, peneliti mendeskripsikan satu siswa yang memiliki kemampuan komunikasi tertulis dan lisan paling baik di antara keempat siswa lainnya. Hasil penelitian ini menunjukkan bahwa dari tiga domain literasi spasial, siswa hanya mampu mencapai semua indikator-indikator domain visualisasi dan penalaran. Sedangkan untuk indikator-indikator domain komunikasi, siswa hanya mencapai dua dari empat indikator.

Abstract

Linear algebra is an area of mathematics that is widely considered challenging. One of the subjects covered is the system of linear equations in two variables. During their first year of college, Pre-Service Teachers (PST) study this subject using increasingly sophisticated approaches and theories. The objective of this qualitative study is to classify and describe the Mathematical Thinking Trajectories (MTT) of PST in solving a system of linear equations in two variables problems. Thirty-three PST majoring in mathematics education who enrolled in the Errors and Misconceptions in Mathematics course participated in this study, which used written answers as research data. The Three Worlds of Mathematics theory framework is used in this study. Seven MTT classifications were identified by the research findings: (1) embodied, (2) symbolic, (3) embodied-symbolic, (4) symbolic-embodied, (5) formal, (6) embodied-symbolic-embodied, and (7) symbolic-embodied-symbolic. “Embodied” refers to how PST applies mathematical ideas that focus on actual objects, “symbolic” focuses on symbols, operations, and their properties, and “formal” focuses on definitions, theorems, and logical procedures. In learning practices, the results of this study can be applied to create learning that is meaningful and that fosters the growth of algebraic thinking abilities.

Abstract

Student positioning in discussion activities with group change patterns can be used to determine student positions when interacting with group members. Group changes are useful for deciding student positions in three meetings held. The purpose of this study was to describe how student positioning occurs in discussion activities with group change patterns. The research method used is descriptive qualitative research with a phenomenological type. The research instruments were group worksheets, student observation sheets, and documentation in pictures and recordings. Data analysis in this study was data reduction, data presentation, and conclusion. The results showed that with student positioning, students could determine their positions during interactions in discussion activities. The interaction resulted in group changes used to determine the differences in the positions of the four students at each meeting, as well as the consistency of student positioning to determine the extent to which the four students were consistent in providing ideas or suggestions.

Abstract

This research aims to explore students’ proportional reasoning at the early attempts at quantifying stage when students face proportional situations, especially mathematical literacy problems. This research uses a qualitative research approach involving grade 9 junior high school. Data was collected by providing mathematical literacy problems containing proportional situations and in-depth interviews with research subjects. The research results show that students in the early attempts at quantifying stage begin to identify important variables, recognize regularities, and develop plans to solve problems. Students apply inappropriate addition relationships in proportional situations, add or subtract numbers without understanding the concept of comparison, and have a sense of comparing sizes that are bigger and smaller, but students have limitations in understanding the concept of proportionality, especially in recognizing when comparison should be used, students try to identify comparative patterns, students have difficulty connecting patterns to multiplicative forms; able to conclude, but the conclusions are wrong due to limitations in understanding the concept of proportionality which results in inaccurate results. This study provides a novel contribution by specifically focusing on the “early attempts at quantifying” stage, a crucial yet underexamined phase in proportional reasoning development. The findings fill a gap in understanding how students transition from additive to multiplicative reasoning when faced with real-world mathematical problems. The implication is that assistance is needed in the form of exercises that increase students' understanding and sensitivity to multiplicative situations and relationships between variables in solving mathematical literacy problems.
