Abstract

Learning is evolving rapidly in the 21st century, as evidenced by advancements in science and technology (IPTEK), including the use of comics as a medium for learning mathematics. The incorporation of ethnomathematics comics based on the architectural features of Masjid Al-Akbar Surabaya serves as an innovative learning tool to address issues such as unengaging media and students’ reluctance to learn mathematics. This study aims to: (1) examine the process of developing ethnomathematics comics about the Al-Akbar Mosque of Surabaya to help elementary school students recognize the names and characteristics of geometric structures; (2) assess the feasibility of these comics as a learning medium; and (3) analyze teachers' and students' responses to their implementation in the classroom. This study employs a research and development (R&D) approach using the ADDIE development model, which consists of four stages: analysis, design, development, and implementation. Data collection methods include documentation, surveys, observations, interviews, and literature reviews, while data analysis combines qualitative descriptive and quantitative techniques based on expert validation and Likert-scale responses. The results indicate that (1) the three initial stages of the research process—analysis, design, and development—were successfully carried out according to the established framework; (2) validation data from material experts, linguists, and learning media specialists rated the comics as "highly feasible"; and (3) responses from class II-A teachers, expert teachers, and four class II-A students also confirmed a "highly feasible" rating. These findings suggest that the developed ethnomathematics comics based on the Al-Akbar Mosque are effective and appropriate for elementary school students in learning about geometric structures. This research contributes to mathematics education by integrating ethnomathematics into instructional media, fostering cultural appreciation while enhancing students' understanding of geometric concepts. Additionally, it provides a structured framework for developing ethnomathematics-based learning resources that can be adapted to other cultural and architectural contexts.

Abstract

Literary works are written based on the author's experience. The author tries to reflect and analyze the events he experienced into his work. Such a process can be said to be an imaginative process. Besides imagination, writers also need special techniques so that the work presented is well and interesting. One technique that can be used is four mathematical thinking patterns. The four mathematical mindsets include a square mindset, cross mindset, similarity mindset, and difference mindset. This technique functions for regional awareness, conflict building, resolution building, and diction selection. This technique is used by PGSD Study Program students to create short stories. The method in this article uses a qualitative research design with exploratory research types to understand the text and context. Data analysis was carried out by comparing short stories with four mathematical thinking techniques. The results of the research show that PGSD Study Program students understand the rules of short story writing, and can implement the four mathematical thinking techniques for creating short stories.

Abstract

This study investigates the influence of mathematics anxiety on the critical thinking processes of primary school students when solving numeracy tasks. Using a qualitative case study design, data were collected through written responses and follow-up interviews with students categorized according to their levels of mathematics anxiety. Analysis focused on three indicators of critical thinking: clarification, strategy, and inference. The findings show that students with high mathematics anxiety typically demonstrated the ability to extract key information from problem statements and diagrams, demonstrating strength in clarification. However, their ability to formulate strategies and provide justified inferences was limited, as they often relied on rote recall, omitted calculation steps, and expressed uncertainty about their answers. These patterns show how anxiety specifically hampers the ability to perform calculations and make confident decisions, even when students demonstrate basic comprehension. The study underscores the need for pedagogical approaches that simultaneously develop numeracy skills and address affective barriers, thereby supporting students’ capacity to engage in reasoning and problem solving more effectively.

Abstract

Purpose: This study explores the effect of culturally responsive teaching (CRT) and learning motivation on numeracy achievement among elementary students in coastal West Papua, Indonesia. It investigates how integrating local cultural contexts into mathematics instruction and fostering student motivation can enhance learning outcomes. Method: A quantitative ex post facto design was applied, involving 30 third-grade students from SD Negeri 35 Kimindores. Data were gathered through a culturally responsive teaching scale, a learning motivation questionnaire, and a contextual numeracy test. Multiple regression analysis was used to assess the relationship between these factors. Finding: The analysis revealed that both culturally responsive teaching and learning motivation significantly impacted numeracy achievement, explaining 69% of the variance in students' performance. Students exposed to culturally relevant lessons showed greater motivation and improved numeracy skills. Significance: The study highlights the value of culturally responsive pedagogy in improving student engagement and achievement in mathematics. By aligning lessons with students' cultural contexts, educators can make learning more meaningful and inclusive. This research emphasizes the need for culturally grounded teaching strategies, particularly in remote areas, to ensure educational equity and foster deeper learning.

Abstract

Purpose: This study aims to understand how the cultural elements of Surabaya’s Tugu Pahlawan Monument can be used to introduce basic numeracy in primary school, especially concepts related to plane geometry. The goal is to show that cultural landmarks can offer real and relatable examples for young learners. Method: The research was conducted through a qualitative ethnographic approach. The researcher observed the monument directly, spoke with on-site guides and staff who were familiar with its history, and documented various architectural and visual features. All information gathered from notes, photographs, and short interviews was analyzed using the Miles and Huberman framework to identify patterns that relate to mathematical ideas. Findings: The study found that many parts of the monument display clear geometric forms. These include rectangles, squares, circles, triangles, trapezoids, rhombuses, and even a ten-sided figure. Such shapes appear in the floor patterns, plaques, murals, decorative ornaments, museum structures, and the wheels of military displays. Each of these elements can be directly connected to geometry topics taught in primary classrooms. Significance: The findings highlight the potential of local heritage as a meaningful resource for mathematics education. When students see that the shapes they learn in class appear in a monument tied to their own city’s history, mathematical concepts become easier to grasp and more engaging. This approach supports early numeracy while also helping learners build a stronger connection to their cultural environment.
