Abstract

Mathematics and culture cannot be separated from each other in everyday life, because culture and mathematics are a whole unit and are used to solve everyday problems. The relationship between culture and mathematics is called ethnomathematics. The purpose of the research is to reveal the mathematical concepts contained, while the target is the shape of flat and spatial shapes. This research uses a qualitative method with an ethnographic approach. Data were obtained through direct observation, documentation, and image analysis. The identification of geometric shapes is done by analyzing the shape of buildings, such as flat and spatial shapes, to understand the mathematical concepts contained in the temple design. This study found that the design of Klaten Untoroyono Temple contains elements of geometry such as square, triangle, trapezoid, cube, block, and pyramid. These findings support ethnomathematics as an innovative and fun learning method to understand math concepts through culture.

Abstract

This article presents a community engagement-based research initiative aimed at enhancing numeracy competence among senior high school teachers in Indonesia through a cybernetic pedagogy framework. Conducted at SMA Negeri 1 Nguter, the program combined theoretical workshops, digital tool integration, and cross-disciplinary lesson design to empower teachers in embedding numeracy across various subjects. A mixed-methods approach—comprising pre- and post-tests, structured mentoring, classroom observations, and reflective journals—revealed significant improvements in teachers' conceptual understanding, pedagogical confidence, and instructional practices. The findings demonstrate that cybernetic-based teaching fosters interactive, data-driven learning environments and supports numeracy as a transversal 21st-century skill. This study contributes empirical insights into scalable, cross-national professional development models that can be adapted in resource-constrained educational contexts

Abstract

This study aims to understand the students’ computational thinking skills in statistics. The type of research is descriptive with a qualitative approach. The data collection techniques in this study include 1) Tests; 2) Interviews; 3) Documentation; and 4) Validation Sheets. The data analysis in this study involves: 1) Data condensation; 2) Data presentation; 3) Verification; and 4) Conclusion drawing. The validity of the data in this study is ensured using the technique of triangulation. Subjects were selected using purposive sampling. The instruments used were two statistical problem-solving questions. The results showed that in solving the first and second questions, the respondents could address the problems using the components of Computational Thinking, starting with decomposition, abstraction, and algorithm tasks. However, the pattern recognition component was not evident in the problem-solving process, even though some respondents gave incorrect answers. This was because the respondents did not fully understand the questions. They only read the questions once or twice, so the information was not fully comprehended. Additionally, the respondents only considered the simplest path and overlooked more complex paths in solving the second question. Students can carry out abstraction and algorithmic tasks, but they still struggle with decomposition and pattern recognition.

Abstract

The purpose of the study was to find out whether there is an influence of basic integral learning video media on learning outcomes for Class XI MIPA students at SMA Negeri 1 Polokarto, Sukoharjo Regency, in the 2022/2023 academic year. This study uses a type of experimental research with a quantitative approach. With a population of all class XI MIPA students at SMA N 1 Polokarto for the 2022/2023 academic year, Sukoharjo Regency, there are 142 students and 4 classes. In this study using purposive sampling technique. This consideration was taken based on the number of students between the two classes being the same and the standard deviation values being relatively the same. The two classes that became the experimental and control classes were XI MIPA 1 and XI MIPA 2 with basic integral discussion material. Learning outcomes can be seen in the hypothesis test, it is known that the value of the independent sample t-test, with H0 is accepted if tcount ? ttable and H0 is rejected if tcount < ttable by determining dk = n1 + n2 - 2 with a significant level of ? = 5%. It can be seen that tcount = -5.151 and ttable = 1.994. Then the calculation results can be seen that tcount < ttable, namely -5.151 <1.994 means that H0 is rejected., and the results of observations of student activity during activities on basic integral material the average value of the percentage of observations in the experimental and control classes , showing the results of student activity in the experimental class was higher than the control class. This can be seen from the percentage of the average value of the two observers who were carried out in the experimental class by 95% while in the control class by 83.3%. Based on the results of research data analysis, seen from the results of learning to test the hypothesis and the percentage of the average value of observations, it can be concluded that there is an influence of learning video media in helping to understand Basic Integral material on student learning outcomes in class XI MIPA SMA Negeri 1 Polokarto, Sukoharjo Regency, Academic Year 2022/2023 .

Abstract

The aim of this research to describe the learning difficulties of Mathematic Student on Real Analysis with an Online System. The results of this study expected to be considered making policies to overcome learning difficulties. This research used a descriptive method with a qualitative approach. The researcher used questioner and interview to collect the data. The result of this research showed that the learning difficulties of Mathematic Student on Real Analysis with an Online System were influenced by two factors, they are an internal factor (from the students themselves) and an external factor (from outside of students). The first internal factor that causes learning difficulties is the interesting aspect with a percentage of 64.05% in quite hinder category, and this is because the student chooses real analysis learning, which is actually done face to face. The second internal factor is the motivation aspect, with a percentage of 70.71% in quite hinder category. This is because the student lacks the effort to learn real analysis. The third and fourth internal factors are the talent aspect with a percentage of 50.71% in a hinder category and the philosophical aspect with a percentage of 53.21% in a hinder category. This is because the student assumes that real analysis difficult subjects because the material is in the form of theorems and proofs. The first external factor that caused the learning difficulties is the infrastructure from the family, with a percentage of 64.64% in quite hinder category. This is because students don't have the complete infrastructure to support online learning. The second external factor is the lecturer quality aspect, with a percentage of 71.43% in quite hinder category. This is caused by the speed lecturer delivering learning material. The third external factor is the lecturers' learning method aspect, with a percentage of 58.92% in the hinder category. This is because, in learning, lecturers only use WhatsApp. The fourth external factor is the university facilities aspect, with a percentage of 59.29% in the hinder category. This is because subsidy pulse/quota given to students only a hundred thousand and must be used for 4-5 months of online learning.
