Abstract

This research aims to develop an instrument to improve conceptual understanding of number operation materials owned by prospective teachers at IKIP PGRI Pontianak. This research is a development research. The subjects in this study are students in the third semester of the Mathematics Education Study Program, Faculty of Education, Mathematics and Technology, as many as 20 students who were randomly selected. The main instrument is the researcher himself, while the supporting instruments are the task of number operation problems and interview guidelines. Data analysis is carried out descriptively on all data obtained. The results of the analysis show that the form and type of learning instrument that is suitable for improving students' conceptual ability, especially in the interpretation ability in number operation material, is a multiple-choice sample problem unit. Students' interpretation skills in number operations material are not good because they still have the opportunity to understand and apply the concept of operations on numbers. Learning instruments in the form of units of multiple-choice questions of the second type are practical to be applied with the aim of improving students' conceptual abilities, especially interpretation skills in number operation materials

Abstract

This study aims to analyze the distribution of zakat in Indonesia, focusing on the portion of zakat distribution to each asnaf in 2023. Zakat, as one of the pillars of Islamic economics, has an important role in reducing social inequality and improving people's welfare. The distribution of zakat in Indonesia is managed by various zakat institutions, one of which is Baitulmaal Munzalan Indonesia. This study uses a descriptive qualitative approach with content analysis to describe the distribution of zakat to five asnaf, namely fakir, poor, fi sabilillah, muallaf, and ibn sabil. The data used was obtained from 35 branches of Baitulmaal Munzalan throughout Indonesia in 2023. Data analysis was carried out qualitatively with the stages of data reduction, data presentation, and conclusion drawn. The results of the study show that the allocation of zakat is more given to the poor and Fi Sabilillah, while the Fakir, Muallaf, and Ibn Sabil get a lower allocation. This study also identifies various factors that affect the imbalance in zakat distribution, such as limited data collection, priority of zakat institutions, and socio-economic factors. Recommendations are given to increase the equitable distribution of zakat in the future

Abstract

Background: Spatial reasoning is a fundamental component of geometry learning, particularly in translating between two-dimensional nets and three-dimensional geometric shapes. For prospective mathematics teachers, the ability to perform such spatial translations is essential because it influences conceptual understanding and future instructional practices. However, correct answers in spatial tasks do not always indicate genuine conceptual understanding. Aims: This study aims to explore and describe the thinking processes of prospective mathematics teachers when translating spatial representations, specifically from nets to geometric shapes and from geometric shapes to nets. The scope focuses on identifying qualitative characteristics of their thinking processes in spatial translation tasks. Methods: This research employed a qualitative approach involving 12 prospective mathematics teachers enrolled in the Mathematics Education Study Program, Faculty of Mathematics, Natural Sciences, and Technology, Universitas PGRI Pontianak. Participants were selected using purposive sampling. Data were collected through spatial translation tasks followed by semi-structured interviews. Interview data were audio-recorded, transcribed verbatim, and analyzed qualitatively to identify patterns in participants’ thinking processes. Result: The findings revealed five distinct characteristics of thinking processes: (1) correct and understanding the concept, (2) correct but not understanding the concept, (3) correct through reflection, (4) wrong but understanding the concept, and (5) wrong and not understanding the concept. The results indicate that answer correctness does not necessarily reflect conceptual understanding, and that reflection plays a crucial role in reconstructing spatial concepts. Conclusion: This study emphasizes the importance of conceptual understanding and reflective thinking in geometry instruction and provides insights for mathematics teacher education programs in designing learning experiences that develop prospective teachers’ spatial reasoning skills.

Abstract

Penelitian ini dimaksudkan untuk mengkaji penguasaan siswa terhadap mengalihkan bentuk representasi guna menyelesaikan masalah kovariasional pada materi statistika. Latar belakang penelitian menunjukkan bahwa siswa sering mengalami kesulitan dalam memahami soal matematika yang disajikan dalam berbagai bentuk representasi seperti tabel, grafik, verbal, dan simbol. Penelitian ini dikonstruksi menggunakan paradigma deskriptif-kualitatif dengan strategi studi kasus sebagai landasan eksplorasi data. Subjek penelitian terdiri dari sembilan siswa kelas VIII SMP Negeri 10 Sungai Kakap yang dipilih berdasarkan hasil tes kemampuan translasi representasi. Instrumen yang digunakan adalah tes tertulis dan wawancara semi terstruktur. Data dianalisis berdasarkan empat indikator kemampuan translasi representasi, yaitu membongkar sumber, koordinasi awal, mengonstruksi target, dan menentukan kesetaraan. Hasil penelitian menunjukkan bahwa siswa dengan kemampuan tinggi mampu melakukan seluruh proses translasi representasi dengan baik dan akurat. Siswa dengan kemampuan sedang mampu menyelesaikan proses translasi dengan beberapa kesalahan pada tahap koordinasi atau kesetaraan. Sedangkan siswa dengan kemampuan rendah mengalami kesulitan hampir di semua indikator, terutama pada tahap mengonstruksi target dan menentukan kesetaraan. Temuan ini menunjukkan pentingnya pembelajaran yang mengintegrasikan berbagai bentuk representasi dalam meningkatkan kemampuan pemecahan masalah siswa.

Abstract

This research aims to describe the learning obstacles experienced by tenth-grade students of SMA Negeri 1 Batu Ampar in solving problems related to statistical material. This study employs a qualitative approach within the form of a case study. The research subjects were selected using purposive sampling, consisting of six students categorized by high, medium, and low ability levels. The data were collected through diagnostic tests, interviews, and documentation, and then analyzed through several stages, including data processing, data classification, data analysis, and drawing conclusions. The validity of the data was tested using source triangulation. The findings indicate that students still experience difficulties in understanding statistical concepts, particularly in determining the mean, median, and mode, selecting appropriate problem-solving steps, and interpreting data. These learning obstacles manifest in the form of calculation errors, procedural mistakes, and the inability to apply concepts to different problem contexts. Furthermore, the results show that students’ learning challenges are influenced by several factors, including: (1) Internal factors, such as low conceptual understanding, lack of mastery of prerequisite material, low learning motivation, and the tendency to memorize formulas without understanding their meaning; (2) External factors, including instructional methods that remain procedural and provide limited gradual practice; and (3) Learning material factors, particularly limited variations of example problems and lack of contextual presentation. These findings indicate that the learning process still requires reinforcement in conceptual understanding, diverse practice exercises, and more contextual learning strategies in order to minimize learning obstacles among students.Keywords: Diagnostic test, Learning Obstacle, Material understanding, Statistic.
