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.

Abstract

Interactive learning multimedia is needed to improve students’ numeracy literacy skills. Based on this, this study aims to analyze the validity, practicality, and effectiveness of interactive learning multimedia assisted by Scratch to improve students’ numeracy literacy skills. Based on this, this study aims to develop and evaluate interactive multimedia learning assisted by Scratch to improve students' numeracy literacy skills. This study used a Research and Development (R&D) method based on the ADDIE model. In this study, the sample comprised 32 students from class VII A at SMP Negeri 2 Temanggung. The Sampling technique used was cluster random sampling. Data collection techniques used questionnaires, interviews, completing test questions, and observations. The novelty of this research lies in the development of interactive multimedia using Scratch, a tool that has not previously been used to improve numeracy literacy skills. The multimedia developed was categorized as very valid, with material validity of 85.64% and media validity of 85.78%. Its practicality was also rated very high, as indicated by student responses of 85.94% and teacher responses of 90%.  The multimedia also proved effective in improving numeracy literacy skills, as indicated by the N-Gain score of 0.5550 (moderate category) and significant differences between pretest and posttest results (t = 9.554, df = 31, p < 0.05). Interactive multimedia learning assisted by Scratch was also found to be very practical, with 85.94% of students responding positively in the student response questionnaire and 90% in the teacher response questionnaire. Thus, it can be concluded that interactive multimedia developed using Scratch is valid, practical, and effective in improving students’ numeracy literacy skills. Keywords: numeracy literacy, interactive multimedia, scratch.

Abstract

Dynamic thinking is a crucial cognitive skill that enables students to solve complex problems in geometry effectively. This study investigates the characteristics of dynamic thinking among prospective mathematics teachers, focusing on the four key aspects: technique, conceptualization, monitoring, and perception. While previous research has identified these aspects, the specific problem-solving characteristics of dynamic thinking in mathematical contexts remain unexplored. This qualitative study was conducted at Tidar University, involving 54 prospective mathematics teachers identified as dynamic thinkers. Data were collected through a two-stage problem-solving test, structured observations, and in-depth interviews. The research instruments underwent a validation process to ensure reliability. Data analysis followed a systematic approach involving reduction, presentation, and verification to extract patterns of dynamic thinking among proficient problem solvers. The results indicate that students who exhibit proficient dynamic thinking demonstrate completeness and consistency in all four aspects. They effectively integrate multiple strategies, adapt their approaches in response to challenges, and maintain a reflective understanding of their problem-solving processes. Additionally, proficient dynamic thinkers show a higher degree of flexibility and spatial reasoning in geometry problems. This study contributes to the existing body of knowledge by identifying and describing the specific characteristics of dynamic thinking in mathematical problem-solving. The findings provide valuable insights for teacher education programs, emphasizing the need to cultivate dynamic thinking skills among prospective math educators. Future research can explore dynamic thinking across different mathematical domains and cognitive frameworks.

Abstract

The existence of a Student Worksheet (LKPD) is able to improve the ability to understand students' concepts. This research aims to develop LKPD based on ethnomathematics of batik motifs typical of Magelang in terms of the ability to understand concepts based on validity, practicality, and effectiveness in geometric transformation materials. The type of research used is research and development (R&D) with a 4D model, namely the defining stage, the design stage, the development stage, and the deployment stage. This study was conducted at SMP Negeri 1 Tegalrejo with a sample of 31 students in class IX B. The results showed that an LKPD based on ethnomathematics of batik motifs typical of Magelang was produced to increase understanding of the concept of geometric transformation that is valid or feasible in terms of the validity value of LKPD by material expert validators and teaching material expert validators, which is 86.31% with a very valid category. Judging from the practicality value of LKPD by the response of students, which is 89.61% with a very practical category. The results of the standard gain increased concept understanding ability were obtained by 5 low classification learners, 10 medium classification students, and 16 high classification students. Increasing understanding of the concept of geometric transformation using LKPD based on ethnomathematics of batik motifs typical of Magelang in terms of the effectiveness value of the pretest and posttest results calculated using the standard gain formula <g> , which is 0.62 with a moderate category, so that LKPD is said to be effective.

Abstract

As many as 7.03% of people with disabilities in Indonesia are deaf people. The problem for deaf students is the lack of mathematics learning resources during learning and the low mathematical communication skills of deaf students. The purpose of this study is to analyze the development of sign language learning videos to improve mathematical communication of deaf students of fractional material in terms of validity, practicality, and effectiveness. The method used is the R&D method with a 4D model. The results showed that the validity of the media resulted in a very valid category by sign language experts with a score of 85% and material experts with a score of 83% and categories valid by media experts with a score of 78.5%. The results of media practicality of 100% for teacher and student responses and learning implementation questionnaires are said to be very practical. The results of the control class pretest and the experiment resulted in a sig value. > 0.05, then the data is normal. Homogeneity test with (6,14) <  (19) on pretest questions and (4,68) <  (19) on posttest questions then homogeneous data. Student scores resulted in a difference in the average student learning outcomes between the experimental class and the control class indicated by the T test results with the sig value. (0.001) < 0.05. The average value of the N Gain of the experimental class is greater than that of the control class, which is 0.9721 with a high category. so that the media is said to be valid, practical, and effective.
