Abstract

This study aims to describe the learning obstacles faced by students in the operation of integers. The research method used is a qualitative method with a case study design. The data was taken from 16 students in grade 7, a junior high school in Batang Hari, Jambi. The data collection technique used was triangulation data. There are written tests, interviews with both students and the teacher, and document analysis. The data collection instrument used was a test of integer operations, interview guidelines, and documents (lesson plan and textbook). The results of the research showed that there are learning obstacles in the operations of integers, namely, ontogenic obstacles (difference in knowledge between natural number operations and integer operations), epistemological obstacles (limited understanding), and didactical obstacles (obstacles that come from the didactic system). Other researchers can create lesson plans based on the obstacles found in this research.

Abstract

The gap between the concept image and the concept definition will greatly affect a persons understanding of the concept. This study aims to reveal the gap between the concept image and the concept definition, and the causes of the emergence of the gap. The research subjects were 16 first-year mathematics students at one of the universities in Aceh, Indonesia. Data were obtained from the results of written tests and in-depth interviews. This qualitative research with a phenomenological study approach was analyzed descriptively. The results showed that the gap that occurs in the concept includes: the division of a non-zero number by zero yields infinity, the concept of dividing zero by zero is zero, the concept of dividing a number by zero is the same as the concept of the limit, e.g., , and the concept of the left-hand limit as means that the satisfied value of x is all negative numbers such that . The emergence of these concept images results from the subject's learning experience at school and a calculus course. This finding provides insights and considerations for educators to comprehensively introduce students to the concept of infinity to avoid misunderstandings in limit and next materials.

Abstract

Penelitian ini bertujuan untuk menganalisis kemampuan Computational Thinking (CT) siswa SMP dalam menyelesaikan soal matematika pada materi deret aritmetika ditinjau dari Kemampuan Awal Matematis (KAM). Penelitian ini menggunakan pendekatan deskriptif kualitatif dengan subjek siswa kelas VIII yang dipilih berdasarkan kategori KAM tinggi, sedang, dan rendah. Instrumen penelitian terdiri dari tes uraian dan pedoman wawancara. Hasil penelitian menunjukkan bahwa siswa dengan KAM tinggi mampu memenuhi seluruh indikator CT, yaitu decomposition, pattern recognition, abstraCTion, dan algorithm. Siswa dengan KAM sedang hanya mampu memenuhi sebagian indikator, sedangkan siswa dengan KAM rendah cenderung hanya memenuhi dua indikator awal. Temuan ini diperkuat oleh hasil wawancara yang menunjukkan bahwa siswa dengan KAM rendah mengalami kesulitan dalam menyusun strategi penyelesaian yang sistematis. Penelitian ini menyimpulkan bahwa KAM berperan penting dalam mendukung kemampuan CT siswa, sehingga diperlukan pendekatan pembelajaran yang adaptif dan kontekstual.   This study aims to analyze the Computational Thinking (CT) skills of junior high school students in solving arithmetic sequence problems based on their prior mathematical ability (KAM). A descriptive qualitative approach was employed, involving grade VIII students categorized into high, medium, and low KAM levels. Research instruments included problem-solving tests and interview guidelines. The findings indicate that students with high KAM were able to meet all CT indicators: decomposition, pattern recognition, abstraction, and algorithm. Students with medium KAM demonstrated partial mastery, while those with low KAM mostly fulfilled only the first two indicators. Interview results confirmed that low-KAM students had difficulty constructing systematic problem-solving strategies. The study concludes that prior mathematical ability plays a significant role in supporting students' CT skills, thus emphasizing the need for adaptive and contextual learning approaches.

Abstract

The differences in the characteristics of field dependent and field independent students in applying their mathematical literacy affect the results of students' work in solving mathematical problems. This study aims to identify students' mathematical literacy abilities viewed from cognitive style especially field dependent and field independent students in solving mathematical problems. This study uses a case study method with a qualitative approach which was carried out in one of the junior high schools in North Bengkulu Regency, Bengkulu Province, involving 32 students of class VIII in the 2022/2023 academic year who had studied number pattern material as participants. The subjects in this study were selected purposively, namely 3 students with a Field Dependent (FD) cognitive style. Data in the study were collected using the Group Embedded Figure Test (GEFT), mathematical literacy tests, and interviews. The research findings show that the majority of students have a cognitive style FI compared to FD. Most students achieved mathematical literacy skills at level 3. In terms of cognitive style, from the five levels of questions given, level 1-level 5, FD subjects with low, medium, and high initial mathematical abilities (KAM) achieved mathematical literacy up to level 3. The students met the formulate, employ and interpret indicators but still had difficulty writing mathematical symbols.
