This study aims to comprehensively investigate students' learning approach in identifying, predicting, and generalizing object and number configuration. A qualitative method was applied with as many as 28 participants from eighth-grade students in Bandung, Indonesia. Students’ ability to recognize, predict, and generalize the configuration of objects and numbers was assessed. At the same time, the approaches employed in the process were analyzed. The research showed that students used different approaches to figure out the pattern of objects and number configuration. These approaches were: descriptive, operational, visual-descriptive, visual-operational, and descriptive-visual-operational. Keywords were typically employed in the descriptive approach to predict unknown objects or numbers. However, the descriptive approach could not accurately predict specific patterns. Therefore, students employed other approaches, including operational, visual-descriptive, visual-operational, and descriptive-visual-operational approaches. Unfortunately, all approaches have proven inadequate for formulating generalizations (general rules) independently. These results showed that when teaching students how numbers and objects are configured, they should be encouraged to try different ways of seeing patterns, such as descriptive, visual, operational, or a combination of the three.

This study aims to determine the effect of Kometika, a board game, on media and numeracy literacy, as well as its impact on the learning outcomes of students whose scope is limited to Madrasah Tsanawiyah. There are some problems related to numeracy literacy learning in Islamic schools (madrasahs), some of which are the result of Asesmen Kompetensi Madrasah Indonesia (AKMI) and the low interest in numeracy literacy, which affects the low learning output. The research method employed was a quantitative experiment utilizing treatment-by-level designs. The findings showed that the average scores of students who studied using the Kometika board game media were higher than those of students without the Kometika board game media. The numeracy literacy interest of students who studied using the Kometika board game media was higher than that of those who studied without it. There was an interaction effect between the use of Kometika board game media and students' interest in numeracy literacy in relation to the learning outcomes. This means that Kometika board game media and numeracy literacy interest are interdependent and affect learning outcomes; therefore, support from related stakeholders, such as the head of the madrasah and teachers, is urgently needed. This study makes a significant contribution to the field of educational media and numeracy literacy, particularly within the context of Islamic education institutions. The research expands current pedagogical strategies aimed at improving numeracy skills among Madrasah Tsanawiyah students.

Pythagorean's theorem is a fundamental concept in mathematics that is widely used in various fields, including geometry, physics, and engineering. The ability to understand and apply these theorems is important in solving geometric problems and calculating distances or angles in real contexts. However, there are learning obstacles and difficulties for students in solving the problems of the Pythagorean theorem. This study aims to describe the learning obstacles and difficulties of students in solving Pythagorean theorem material through Systemic Literature Review (SLR). The article search strategy applies inclusion and exclusion criteria. The selection process was 19 selected articles using CASP checklist with articles coming from Google Scholar, Scopus, Springer Link, IEEE Explore, and PubMed databases. Based on the results of the study, it was obtained that students' learning obstacles came from epistemological obstacles, ontogenic obstacles, and didactical obstacles. The students' difficulties are dominated by conceptual difficulties. Learning obstacles cause learning difficulties. Studying students' learning obstacles and difficulties can assist a teacher identify student learning problems. Keywords: learning difficulties, learning obstacles, pythagorean theorem, systematic literature review.DOI: http://dx.doi.org/10.23960/jpmipa/v25i4.pp1939-1960

Kemampuan untuk memahami dan mengaplikasikan konsep-konsep aljabar menjadi kunci dalam pengembangan kemampuan berpikir analitis dan pemecahan masalah yang kompleks. Oleh karena itu, kompetensi guru dalam mengajar aljabar, seperti menyusun instrumen, sangat penting untuk memastikan bahwa siswa dapat memahami dan menguasai materi ini dengan baik. Metode yang digunakan dalam kegiatan pengabdian kepada masyarakat ini adalah pelatihan (workshop) yang memadukan pendekatan daring dan luring. Workshop ini bertujuan untuk mengasah kemampuan guru matematika Madrasah Tsanawiyah (MTs) se-Kota Bandung dalam menyusun Instrumen Numerasi Konten Aljabar Tipe AKM (Asesmen Kompetensi Minimum). Hasil dari workshop telah berhasil mengembangkan 10 instrumen konten aljabar tipe AKM yang valid. Selanjutnya soal diujicobakan kepada 30 siswa. Hasil analisis soal menunjukkan bahwa 18 siswa (60%) berada dalam kategori rendah, sementara 6 siswa (20%) berada dalam kategori sedang, dan 6 siswa (20%) lainnya berada dalam kategori tinggi. Oleh karena itu, diperlukan perbaikan dalam proses pembelajaran.

Learning the Pythagorean theorem is a significant challenge at the junior high school level because students often struggle to understand concepts, connect geometric and algebraic representations, and solve contextual problems. Based on previous studies, students' difficulties indicate the presence of learning obstacles. Existing research has addressed students' difficulties, errors, and epistemological obstacles in solving Pythagorean theorem problems and has presented applications of the Pythagorean theorem. Therefore, this study aims to analyze students' didactic learning obstacles to the Pythagorean theorem topic. To achieve this goal, a qualitative case study was conducted. Data was collected through data triangulation: written tests, interviews, and document studies. At the data-collection stage, 30 students and two teachers participated. Based on the written test results, the answers exhibit various characteristics. At the analysis stage, it is performed using ATLAS.ti software. The results show that there is a form of didactic learning obstacles consisting of visual orientation obstacles and formula procedural obstacles. The Visual orientation obstacles include students' lack of understanding of triangle concepts. The procedural obstacles include students' incomprehension of algebraic representations, understanding of problem-solving, understanding of procedures beyond integers, and application of Puythagos' theorem formulas. Visual orientation obstacles cause formula procedural obstacles. The didactic factor that creates obstacles is the way the topic is presented and the teacher's approach to designing learning. Didactic obstacles analysis is an important step in formulating a hypothesis about how a concept should be taught. By knowing the didactic obstacles, teachers or researchers can develop a more accurate Hypothetical Learning Trajectory (HLT). This will lead to the design of learning activities that anticipate common mistakes and misconceptions. Keywords: didactical obstacle, learning obstacle, topic presentation analysis, textbooks, pythagorean theorem.
