Abstract

Mathematical literacy and ethnomathematics are the two main approaches to understanding mathematics in everyday life. Research on the two aspects should be conducted in an integrated manner. It is expected to be a reference for the development of urban mathematics education based on the social requirements of mathematics and individuals' mathematical competence in a cultural group. The primary goal of this research is to describe the Sundanese people's mathematical literacy through an ethnomathematical perspective. The research is focused on living equipment systems and technology, which is one of the elements of the seven universal culture elements. The study employed phenomenographic and ethnomethodological approaches with a realist ethnographic design. Participant observations and interviews were chosen as data collection techniques, while content analysis, triangulation, and identification of patterns were chosen as data analysis techniques. Ethnomathematics in living equipment systems and technology consists of counting, measuring, explaining, discovering, designing, and explaining activities. The results show that the ethnomathematics of the Sundanese community are relevant to the aspects of mathematical literacy consisting of content, context, and mathematical processes. The study's results emphasize that mathematical literacy and ethnomathematics cannot be separated from daily life.

Abstract

Mathematical reasoning and resilience are essential skills that students need to master in the process of learning mathematics. Both of these skills can be cultivated through instructional models that stimulate students to construct their own knowledge by connecting learning to the real world. One instructional model characterized by these aspects is the Connected Mathematics Project (CMP). Consequently, the purpose of this study is to analyze the effectiveness of the CMP instructional model in enhancing mathematical reasoning and resilience abilities. This research employs a quantitative approach utilizing a quasi-experimental design, specifically the nonequivalent posttest-only control group design. The study was conducted in one vocational high school in Majalengka. Sample selection was carried out using the cluster random sampling technique, resulting in a total of 18 students in the experimental group and 18 students in the control group. The research instruments comprised a mathematical reasoning ability test consisting of three open-ended test items and a mathematical resilience questionnaire. The findings of this study indicate that: (1) students' mathematical reasoning abilities in the CMP instructional model are higher compared to those in conventional instruction; (2) the average percentage of students' resilience attitudes in the CMP instructional model is higher than those in conventional instruction; and (3) CMP instruction is effective in improving both mathematical reasoning and resilience abilities among vocational high school students.

Abstract

This study aims to understand how pre-service mathematics teachers conduct prospective analyses comprehensively. A qualitative research method with a case study design was used. The participant was Mrs N, a pre-service mathematics teacher who conducted research using DDR methodology in a grade 9 junior high school in Sindang, Majalengka, involving 48 students. Data were collected by analyzing empirical evidence from Mrs. N's prospective analysis process by uncovering the various stages of a prospective analysis. An iterative approach was used to analyze the data by refining the research questions through discussions and regular meetings with Mrs. N. The process ensured adaptability to new insights and understandings from the empirical data. Our findings reveal that the teacher draws upon fundamental philosophical principles from didactical design research, including hermeneutics, phenomenology, and ethnomethodology. By embracing these approaches, the teacher gains valuable insights into conducting research within an interpretive paradigm, allowing for a deeper exploration of the meaning of concepts, the purpose of learning, and the cultural influences that shape the educational process. Additionally, our study sheds light on the emergence of transpositional didactics theory as the prospective teacher delves into understanding the meaning of the geometrics transformation concept.

Abstract

In the rapidly changing global landscape, adaptability to new challenges is essential. Mathematics, recognized as a key contributor to problem-solving skills, holds significant importance in navigating unfamiliar situations. This study delves into the correlation between mathematics interest, reading comprehension, and mathematical problem-solving abilities among elementary school students. Employers and academic institutions increasingly emphasize the application of mathematical knowledge in diverse scenarios, prompting educational reforms prioritizing problem-solving skills.The investigation involved 76 elementary students in Majalengka Regency, Indonesia, exploring mathematics interest, reading comprehension, and problem-solving skills using questionnaires and tests. Findings unveiled a noteworthy positive correlation between reading comprehension and mathematical problem-solving, surpassing the correlation with mathematics interest. Regression analysis reinforced this, highlighting the collective substantial impact of mathematics interest and reading comprehension on students' problem-solving proficiency.This study underscores the crucial role of reading comprehension in interpreting narrative-based mathematical problems. Understanding textual content significantly influences problem-solving strategies. Moreover, affective abilities, particularly mathematics interest, contribute significantly to problem-solving skills. A heightened interest in mathematics enhances motivation, encourages deeper conceptual learning, and fosters creativity in problem-solving.These results underscore the necessity of a holistic approach to mathematics education. Addressing not only cognitive aspects but also affective and reading proficiency facets can substantially enhance students' mathematical problem-solving abilities. Understanding the interrelationship among mathematics interest, reading comprehension, and affective abilities can pave the way for more effective teaching methodologies and improved academic outcomes in mathematics.

Abstract

The aim of this study was to investigate the effect of science-based learning on improving mental intelligence in early childhood. A quasi-experimental method was used with two groups, an experimental group that participated in science-based learning and a control group that did not participate in the intervention. Data was collected by pre-testing and post-testing spiritual intelligence in both groups. The results showed that there was no significant difference in the mean pretest score between the two groups. However, after undergoing science-based learning, the experimental group showed a significant increase in the mean posttest score of spiritual intelligence compared to the control group. These findings suggest that science-based learning has the potential to enhance spiritual intelligence in early childhood. Therefore, it is recommended that educators and parents use this approach in early childhood education to strengthen the spiritual intelligence aspect. Although this study has limitations, the results provide insight into the relationship between science-based learning and the development of spiritual intelligence in early childhood.

Abstract

This study investigates elementary school students' 3D geometric thinking skills using the Van Hiele model. The research employed a grounded theory approach, utilizing tests, observations, and interviews to assess students' geometric thinking levels across two elementary schools in West Java and Central Java, Indonesia. A total of 6 test items were developed based on Van Hiele's theory, targeting the visualization, analysis, and informal deduction levels. Results showed varied performance between the two schools. Students from the Majalengka school demonstrated stronger visualization skills (77.14%), while those from the Surakarta school showed better performance in analysis (67.86%) and informal deduction (53.57%). Overall, students exhibited a good foundational understanding of 3D shapes, with most achieving the visualization and analysis levels. However, challenges emerged at the informal deduction level, where students often opted for simpler problem-solving methods over more systematic approaches. The study highlights the effectiveness of the Van Hiele model in assessing geometric thinking development and provides valuable insights for curriculum development and teaching strategies. It emphasizes the need to reinforce visualization and analysis skills while gradually introducing more abstract and systematic thinking in geometry education. The findings contribute to the understanding of elementary students' 3D geometric thinking skills and offer a basis for improving geometry instruction at the primary level.

Abstract

This study aims to improve the mathematical problem-solving ability of students at Vocational High School (VHS) through implementing Project Based Learning (PjBL). The research method used was a quasi-experiment with a matching-only pretest-posttest control group design, with a sample of 64 students divided into two classes, namely experimental and control classes, each consisting of 32 students. The sampling technique used was purposive sampling, where the sample was selected based on specific criteria relevant to the research objectives. Data were collected using tests of mathematical problem-solving ability administered before (pre-test) and after (post-test) the treatment. Data were analyzed using an independent sample t-test and a two-way ANOVA test with univariate general linear model (GLM) analysis. The results showed a difference between the experimental and control groups before the treatment. However, after the treatment, the experimental group had higher mathematical problem-solving ability than the control group, including the improvement and interaction between PjBL implementation and the Early Mathematics Skills (EMS) category.
