Abstract

Extended Reality (XR) which includes AR, VR, MR, has become one of the important innovations in the development of mathematics learning media, especially in the field of geometry. This review aims to analyze the impact, implementation challenges, and future development directions of XR in geometry learning. A PRISMA-based systematic review was conducted with thematic analysis of literature from reputable international journals. The results of the study show that XR improves the effectiveness of learning and spatial thinking skills, student engagement, and learning motivation through interactive visualization and immersive learning experiences. However, negative impacts that need to be considered, include the dependence on technology, physiological and cognitive disorders, and heightened distraction that affects performance. Implementation challenges include limited infrastructure, teacher readiness, device access, costs, appropriate pedagogical design, and curriculum support for optimal XR integration.  Future developments suggest that XR holds strong transformative potential through integration with artificial intelligence (AI), adaptive learning systems, and educational metaverse environments. This study highlights the need for structured XR integration strategies and further research on long-term effectiveness and appropriate XR-based pedagogical design in mathematics learning, particularly geometry.

Abstract

The development of communication and collaboration skills constitutes a critical demand in 21st-century learning. However, classroom practices remain predominantly teacher-centered, limiting students’ opportunities to actively engage in scientific investigation and collaborative work. This study aims to examine the effectiveness of the Investigation-Based Scientific Collaborative (IBSC) learning model in enhancing students’ communication and collaboration skills.This research employed a quasi-experimental design involving students as research participants. The experimental group received instruction using the IBSC model, while the control group was taught using conventional methods. Data were collected through assessment instruments measuring communication and collaboration skills, observation sheets, and supporting documentation. Data analysis was conducted using descriptive and inferential statistics to determine differences between the two groups.The findings indicate that students taught using the IBSC model demonstrate significantly higher communication and collaboration skills compared to those taught through conventional learning. The IBSC model promotes active student engagement in investigative activities, scientific discussions, and collaborative problem-solving, thereby positively influencing their ability to communicate and work effectively in teams.This study concludes that the Investigation-Based Scientific Collaborative (IBSC) learning model is effective as an alternative instructional approach for developing students’ communication and collaboration skills.

Abstract

The purpose of this study was to find out whether the use of graphic organizers integrated with Islamic values can improve students’ ability to comprehend descriptive texts.  Since the true education requires a balance of cognitive development and character development or moral fortitude as the world becomes far from religious path, therefore, this study carried Islamic values as part of classroom English. The subject of this research was grade eight of SMPIT Al-Fauzi Medan of 2023/2024 academic year which consists of 25 students.  Classroom action research was implemented following Kurt Lewin's model with action research procedures, namely planning, implementation, observation, and reflection. This research was conducted in two cycles in each cycle consists of two meetings. Data collection techniques in this study used the following instruments: interviews, field notes, questionnaires, and tests. The results of this study integration of media GO with Islamic values showed significant improvement on students' comprehension on descriptive texts. Students achieve expected grades which is higher than the minimum criteria 70 gradually at the end of the cycle. The average score of the students on the initial test was 51.25.  The average value of students in the first cycle is 58.75.  The average value of students in the second cycle is 72.80. Hence, there are positive responses from students and English teachers regarding to the use of media graphic organizers integrated with Islamic values to improve students’ comprehension on descriptive text.

Abstract

This study examines Differential Item Functioning (DIF) in an instrument developed to measure preservice mathematics teachers’ ethnomathematical knowledge in Jambi. Anchored in the Rasch measurement framework, this study employs a quantitative ex post facto design to evaluate item‑level measurement invariance of an ethnomathematics assessment instrument. Rasch‑based procedures: item and person parameter estimation, fit statistics, and DIF analyses were employed to assess item equivalence across gender, educational background, and teaching experience, and to quantify the magnitude of any detected DIF. Data from 150 preservice teachers were analyzed using Rasch estimation and Mantel–Haenszel DIF on a culturally contextualized ethnomathematics instrument. Descriptive analyses indicated strong psychometric properties of the instrument, with person reliability = 0.81, item reliability = 0.97, and fit statistics falling within acceptable ranges. DIF analyses revealed several items with statistically significant DIF predominantly across gender, while the majority of items demonstrated stable functioning across the examined participant subgroups. Graphical DIF plots revealed heterogeneous item‑response patterns in the ethnomathematics instrument, highlighting the need for culturally responsive item revision to reduce bias. Findings demonstrate the Rasch model’s effectiveness in detecting item‑level bias in instruments measuring preservice teachers’ ethnomathematical knowledge and substantiate targeted refinement of measurement instruments.

Abstract

Determining the molar volume of a real gas requires solving the nonlinear Van der Waals equation. This study aims to compare the efficiency and accuracy of the Newton-Raphson method and the Secant method in solving the Van der Waals equation using the Python programming language. The case study examines the determination of the molar volume of methane gas at a pressure of 56 atm and a temperature of 450 K. The comparison parameters used are the number of iterations and the speed of convergence with an error tolerance of 10⁻⁷. The results show that the Newton-Raphson method requires fewer iterations, namely 4, with a computational time of 0.00012 s. In contrast, the Secant method requires more iterations, namely 6, and a computational time of 0.00015 s. The Newton-Raphson method is less practical because it necessitates the calculation of the derivative of the function, whereas the Secant method is more practical for application in Python scripts as it only requires the calculation of the Van ders Waals equation function.

Abstract

Banyak siswa sekolah dasar mengalami kesulitan dalam mengukur keliling dan luas bangun datar. Pemecahan ini terkait dengan kesalahpahaman, penekanan pada menghafal rumus, dan pengalaman belajar yang bermakna terbatas di berbagai ranah kognitif, afektif, dan psikomotor. Studi ini bertujuan untuk menganalisis kebutuhan pengembangan lembar kerja elektronik siswa tentang keliling dan luas untuk siswa sekolah dasar. Penelitian ini menggunakan tahap analisis dari model pengembangan ADDIE. Data dikumpulkan melalui wawancara guru dan analisis dokumen, termasuk dokumen kurikulum dan lembar kerja elektronik yang ada. Temuan menunjukkan bahwa lembar kerja elektronik saat ini memberikan peluang untuk meningkatkan motivasi dan pemahaman konsepisasi; namun, lembar kerja tersebut belum secara sistematis mengintegrasikan nilai-nilai karakter seperti kejujuran, disiplin, dan kerja sama. Hasil penelitian menyoroti urgensi pengembangan lembar kerja elektronik siswa yang lebih konstruktif yang mengintegrasikan konsep pengukuran matematika dengan pengembangan karakter. Analisis kebutuhan ini memberikan landasan teoritis dan praktis untuk tahap desain dan pengembangan selanjutnya.

Abstract

This study aims to develop a mathematical model based on Integer Linear Programming (ILP) to map unmastered mathematical topics among senior high school students according to the cognitive domains of Bloom's Taxonomy, namely Knowledge (C1), Comprehension (C2), and Application (C3). The research method employed a quantitative approach, utilizing test result data from a 48-item instrument covering 16 mathematical subtopics, administered to 147 twelfth-grade students in the Natural Science program. The data were analyzed using LINDO 6.1 software to generate a profile of student mastery for each subtopic and cognitive domain. The results indicate that student mastery was generally higher in the Knowledge (C1) domain, with eight subtopics achieved, compared to the Comprehension (C2) domain with six subtopics and the Application (C3) domain with five subtopics. Out of the total 48 test items, only 19 items (39.6%) were mastered by the students, while 29 items (60.4%) were not. The Equations and Inequalities (X2) subtopic was the only material not mastered across all three domains. These findings suggest the need for learning strategies that place greater emphasis on strengthening conceptual understanding and contextual application. The application of the ILP model in this study proves effective as a diagnostic tool for identifying student weaknesses in a detailed and objective manner, thereby serving as a reference for teachers in designing targeted remedial programs. Furthermore, this model has the potential to be replicated in other schools to continuously monitor the development of student proficiency.

Abstract

Studi ini bertujuan untuk mengembangkan dan mengevaluasi modul elektronik berbasis etnomatematika yang mengintegrasikan warisan kuliner tradisional Lombok untuk meningkatkan pemahaman siswa sekolah dasar tentang geometri tiga dimensi dalam konteks Kurikulum Merdeka. Dengan menggunakan desain penelitian dan pengembangan (RD) dengan model ADDIE, studi ini melibatkan analisis kebutuhan melalui wawancara dengan guru, kepala sekolah, dan siswa; desain dan pengembangan modul elektronik digital interaktif yang diperkaya dengan unsur budaya dan realitas tertambah; implementasi melalui uji coba terbatas yang melibatkan enam siswa dan uji lapangan dengan dua puluh satu siswa; dan evaluasi melalui validasi ahli dan analisis N-gain. Hasil validasi menunjukkan bahwa modul elektronik tersebut memenuhi kriteria kelayakan, dengan penilaian ahli menghasilkan skor 83% untuk validitas materi, 88% untuk validitas media, dan 80% untuk validitas bahasa. Uji coba terbatas menghasilkan skor N-gain berkisar antara 0,34 hingga 0,92 (rata-rata = 0,69), sedangkan pengujian lapangan menghasilkan nilai N-gain antara 0,00 dan 0,84 (rata-rata = 0,47), yang dikategorikan sebagai peningkatan moderat. Temuan ini menunjukkan bahwa e-modul efektif dalam memperkuat pemahaman konseptual siswa, meskipun peningkatan pembelajaran bervariasi sesuai dengan kemampuan awal dan literasi digital siswa. Studi ini menyiratkan bahwa mengintegrasikan etnomatematika dengan media pembelajaran digital dapat menciptakan pengajaran matematika yang bermakna dan relevan secara budaya.
