Abstract

This study examines the effectiveness of Realistic Mathematics Education, also supported by a website based on ethnomathematics, on the understanding of math concepts among junior high school students. The research method used in this study is quantitative research with a pre-experimental design, one-group pretest-posttest. The sample in the study was 29 students, which was taken from the 8th-grade students of a junior high school in Yogyakarta, picked through cluster random sampling. This study’s instruments were essay tests, which had been validated and proven reliable. The data from the research were analysed by descriptive and inferential statistics, where the inferential statistics included the Normality Shapiro-Wilk test and the One-Sample T-Test. The results indicated a significant improvement in students' understanding of math concepts after using RME through ethnomathematics-based website reach a significant change. This is evidenced by the posttest average value of 82.228, which is far more significant than the Minimum Mastery Criteria value of 75, and 79.31% of the students achieved and exceeded it. These results suggest that including local cultural contexts, batik motifs, and the Borobudur Temple structures in students’ learning process can enhance the students’ conceptual achievement level by strengthening the relationship with the learning process in their daily lives.

Abstract

The shift in learning paradigm from passive to active requires prospective teachers to design meaningful learning experiences, one of which is through a technology-assisted inductive approach. This study aims to analyze the content of lesson plans developed by prospective mathematics teachers to implement technology-supported inductive learning. Using a qualitative content analysis method, this study involved 15 prospective mathematics teacher students from the State Islamic University of Salatiga who had taken courses related to lesson planning. The data sources for this study were lesson plan documents based on inductive learning, including Problem-Based Learning and Discovery Learning. Data were analyzed using thematic analysis to identify hidden patterns and themes. The results show that prospective teachers have integrated technology into each indicator of inductive learning, where the learning stages clearly begin from specific cases or problems to the generalization of concepts. This study contributes to providing an in-depth understanding of how prospective mathematics teachers translate inductive learning theory into lesson planning practices in the digital era, while also identifying aspects that need improvement in teacher training. Future research should investigate the relationship between the quality of lesson plan design and classroom teaching performance. Furthermore, comparative studies involving different technology platforms are needed to identify which tools best facilitate the conceptual discovery phase of inductive learning.

Abstract

The concept of ratio is a fairly important mathematical concept, but it remains a persistent challenge for students. Therefore, this study aimed to optimize 3D representation skills and learning drive by developing epistemic learning patterns integrated with STEAM+X. X referred to aspects of history, culture, and architecture. The research design used was design-based research. Participants in this study consisted of 21 stakeholders in the field of education (teachers, school principals, and academics). The instruments used were a phenomenological questionnaire to explore the causes of students experiencing problems and an integrated STEAM+X ELP module to optimize student competence. The data were analyzed using a combination of thematic analysis and qualitative data analysis. The results revealed that there were five factors that caused low levels of both competencies, namely identity and orientation crisis, spatial experience deficit, motivation and engagement crisis, pedagogical mismatch, and ecosystem limitations. The solutions offered were a student-centered approach, technology and innovation, active and experiential learning, and ecosystem support. All of these components were represented in the form of an integrated STEAM+X ELP module, with the main activity referring to the Subak Lingsar miniature project. Subak Lingsar was chosen because it could support student learning of ratios, such as scale and the rate of change of water flow, as well as comparisons of value and inverse value. This study recommended that the module be implemented in the context of ratio learning by testing its impact on students’ 3D representation abilities and learning drive in schools.

Abstract

Spatial literacy is a vital math skill for students to learn during their three-dimensional geometry education. The two skills remain essential, yet most fifth-grade students struggle with spatial tasks. This challenge restricts their conceptual growth. The research examines fifth-grade students’ spatial literacy abilities and their error patterns to provide evidence for developing a Local Instructional Theory (LIT) on three-dimensional geometry. The research included 118 fifth-grade students (aged 10-11 years) from two public primary schools in Palembang who participated in a descriptive quantitative study with error analysis. The research data came from student performance on the spatial literacy diagnostic test and their error analysis records. The researchers applied descriptive statistics to determine average scores and establish performance levels for visualisation, reasoning, and communication skills. The researchers categorised student mistakes into four categories: procedural errors, conceptual errors, representational errors and communicative errors. The students produced results indicating significant differences in their performances. Students failed to perform basic procedural tasks, including spatial form comparison and application of formal notation, while they struggled with complex visualisation and the development of multiple-step spatial thinking and conceptual understanding. Students’ learning difficulties manifest as systematic errors, indicating that their challenges stem from complex, interconnected issues rather than random mistakes. The research results demonstrate that students need instruction which teaches them to develop their visualisation abilities, their reasoning skills, and explanatory competencies. The designs serve as an essential tool for uniting procedural fluency with conceptual understanding, leading to better spatial literacy in early geometry education.

Abstract

This study investigated the integration of Pancasila values into ethnomathematics-based learning through a project-based learning approach to enhance students’ problem-solving skills. A quasi-experimental design with a pretest–posttest non-equivalent control group was conducted at SMAN 8 Muaro Jambi, involving 62 grade XI students. The instruments consisted of a mathematical problem-solving test, observation sheets, and rubrics for assessing Pancasila values during learning activities. Data were analyzed using paired and independent sample t-tests, normalized gain (N-Gain), and effect size. The findings revealed that the posttest mean score of the experimental class, taught by using the PjBL integrated with ethnomathematics contexts including weaving patterns and local architectuaral designs,was significantly higher than that of the control one (78.94 compared to 69.48). The N-gain of the experimental group (0.61) belonged to medium-high, while that of the control group was only 0.32. Cohen’s d for effect size was 0.82, which was classified as a large effect. Qualitative results also described that collaboration, tolerance, and responsibility in the experimental class were higher, which indicated the implementation of Pancasila values in project activities. The results of this study show that an integration of ethnomathematics and Pancasila values in PjBL can enhance the both student’s problem-solving skills and character.
