Abstract

Mathematical abstraction is an important aspect in mathematics learning, especially in helping students form and understand geometric concepts such as quadrilaterals. However, in practice, students' mathematical abstraction process does not always occur uniformly. This is due to differences in individual characteristics, one of which is learning style. Therefore, this study aims to describe the profile of students' mathematical abstraction in forming the concept of quadrilaterals in terms of learning style. This study uses a qualitative approach with a descriptive type. The research subjects consisted of three seventh-grade junior high school students with visual, auditory, and kinesthetic learning styles. Data were collected through a learning style questionnaire, mathematical abstraction tasks on quadrilaterals, and interviews. Data analysis used data condensation, data display, and conclusion drawing and verification. The results of the study showed that students' mathematical abstraction processes differed in each learning style. Visual students were able to go through all aspects of mathematical abstraction (recognizing, building-with, constructing, and consolidation) gradually by utilizing visual representations. Auditory students also achieved all aspects by relying on verbal understanding, although the constructing and consolidation aspects were not systematically arranged. Meanwhile, kinesthetic students rely more on concrete experiences and physical activity in recognizing and consolidating. Therefore, it can be concluded that learning styles determine how students carry out the mathematical abstraction process in forming the concept of quadrilaterals, so this needs to be taken into consideration when designing mathematics learning.

Abstract

This study aims to describe errors in the construction of mathematical concepts related to exponents in light of mathematics anxiety. This study employs a qualitative approach with two subjects, students with low and high levels of mathematics anxiety. Data analysis uses an iterative model consisting of data condensation, data presentation, and drawing conclusions. The results of the study show that students with low mathematics anxiety exhibit pseudo constructions “incorrect” that is, they provide incorrect answers but are able to correct them after reflection, construction holes in the form of correct answers that are not supported by a complete conceptual understanding, and illogical constructions involving reasoning that does not align with the concept of exponents. Meanwhile, students with high levels of mathematics anxiety exhibited conceptual construction holes because they were not yet able to fully grasp the concept of exponents. Mis-analogical construction involved the use of inappropriate analogies when applying the properties of exponents, while mis-logical construction involved flawed reasoning when solving problems involving exponents. The research findings indicate differences in the types of errors in mathematical concept construction based on students’ levels of mathematics anxiety

Abstract

This study aims to describe the problem-solving process for composition and inverse functions using Polya's stages, based on the mathematical abilities of students at SMA Negeri 1 Pamona Utara. The results show differences in problem-solving approaches according to students' mathematical proficiency. (1) Students with high mathematical ability can accurately identify given and required information, assess the sufficiency of the available data, and understand the relationships between different pieces of information. They can also determine additional necessary information, utilize all essential data, and systematically plan their problem-solving process. Moreover, they are skilled in answering accurately and verifying their solutions by identifying errors. (2) Students with moderate mathematical ability exhibit similar skills in understanding problems and planning solutions. However, in inverse function problems, they struggle to apply systematic steps and are less precise in their answers. (3) Students with low mathematical ability can identify given information and its connections but are unable to develop an effective problem-solving strategy. They still face difficulties in structuring systematic steps to arrive at the correct solution.

Penelitian deskriptif kualitatif ini bertujuan mengeksplorasi profil berpikir kritis siswa laki-laki (TL) dan perempuan (TP) berkemampuan matematika tinggi di SMP Negeri 2 Banawa dalam menyelesaikan masalah Teorema Pythagoras. Subjek penelitian dipilih berdasarkan hasil ujian semester gasal. Data dikumpulkan melalui tes tertulis dan wawancara semistruktur menggunakan instrumen yang telah divalidasi pakar. Hasil penelitian menunjukkan bahwa kedua subjek memenuhi enam indikator berpikir kritis menurut Ennis: Focus, Reason, Inference, Situation, Clarity, dan Overview. Pada indikator Focus, keduanya mampu mengidentifikasi informasi relevan secara logis. Untuk Reason, TL memberikan penalaran praktis, sementara TP lebih detail dan konseptual. Pada Inference, keduanya mampu menarik simpulan, meski TP lebih eksplisit. Dalam indikator Situation, TL menerapkan konsep secara langsung, sedangkan TP menunjukkan aplikasi yang lebih luas. Terkait Clarity, penjelasan TP lebih terstruktur dibandingkan TL yang ringkas namun logis. Pada Overview, TP melakukan tinjauan aktif dengan representasi visual, sementara TL memverifikasi melalui perhitungan langsung. Meskipun memiliki tingkat kemampuan matematika yang sama, ditemukan perbedaan proses berpikir kritis pada keduanya. Perbedaan tersebut terlihat pada strategi penyelesaian masalah, cara mengungkapkan penalaran, serta kejelasan tahapan solusi yang dihasilkan.

Abstract

This study aims to describe the profile of junior high school students' mathematical abstraction in forming the concept of triangles in terms of high, medium, and low levels of mathematical ability, based on the stages of RBC+C, namely recognizing, building-with, constructing, and consolidation. This study uses a descriptive qualitative approach with three seventh-grade students as subjects, one student each with high, medium, and low mathematical ability, selected based on the results of a mathematical ability test. Data were collected through triangle abstraction assignments and interviews, then analyzed using the Miles and Huberman model which includes data condensation, data presentation, and drawing and verifying conclusions. The results showed that students with high mathematical ability were able to pass all stages of RBC+C optimally, students with medium ability were able to reach all stages but not optimally, while students with low ability experienced limitations in almost all stages of mathematical abstraction, especially in the aspects of building-with, constructing, and consolidation. Thus, the level of students' mathematical ability significantly influences the quality of the mathematical abstraction process in forming the concept of triangles.

Abstract

Purpose: This study examined the relationship between whole-number sense and mathematics self-efficacy among Grade IV students in an Integrated Islamic Elementary School (Sekolah Dasar Islam Terpadu, SDIT). It addressed the limited evidence regarding whether students' confidence in mathematics is associated with their foundational numerical competence. Method: A quantitative correlational design was employed involving 126 Grade IV students selected through total sampling. Whole-number sense was measured using a researcher-developed test, while mathematics self-efficacy was assessed through a validated questionnaire. Data were analyzed using descriptive statistics and Spearman's rank-order correlation. Findings: The analysis revealed no statistically significant relationship between whole-number sense and mathematics self-efficacy. These findings indicate that students' confidence in solving mathematical problems was not directly associated with their conceptual understanding of whole numbers in the present sample. Significance: This study extends previous research by examining mathematics self-efficacy in relation to whole-number sense rather than general mathematics achievement. The findings contribute to a more nuanced understanding of the relationship between cognitive and affective dimensions of mathematics learning and suggest that conceptual numerical competence and mathematics self-efficacy should be fostered through complementary instructional approaches in elementary education.
