Abstract

The research aims to examine the effectiveness of the STEM-based approach in 21st-century mathematics learning. The STEM-based approach integrates four main disciplines science, technology, engineering, and mathematics into the learning process to enhance critical thinking and problem-solving skills. The STEM approach is highly relevant to developing 21st-century competencies in mathematics education as both focus on the skills required to address complex and dynamic global challenges, such as critical thinking, problem-solving, creativity, communication, collaboration, and digital literacy. The research method employed is a literature review, analyzing relevant theories and previous studies on the topic. The results indicate that the STEM approach can improve the effectiveness of 21st-century mathematics learning, such as enhancing students' technological development skills, analytical abilities, creativity, innovation, and the ability to express ideas and formulate problems. The STEM approach also stimulates students to meet the demands of 21st-century mathematics learning, which emphasizes critical and problem-solving skills leading to critical, creative, lateral, and systemic thinking abilities.

Abstract

Ethnomathematics studies how mathematics interacts with culture, traditions, and customs of society. With ulos as its identity, this study will investigate one of the Indonesian tribes through its art, namely Ulos art by the Batak tribe of North Sumatra. The form of the Batak ulos variety can be associated with geometric mathematics, so that mathematics can be studied culturally in ethnomathematics studies by integrating the introduction and instillation of culture in the mathematical concepts taught. This research was collected from literature or libraries using a qualitative approach. This study aims to study the concept of geometry in the patterns of North Sumatran ulos cloth from an ethnomathematics perspective. Research shows that science and culture cannot be separated. Batak ulos is not just a traditional cloth; it is also a representation of the hierarchy of cultural values ​​maintained by the Batak people.

Abstract

This research aims to analyze the types of errors made by fifth grade elementary school students in solving mathematical problems. This research uses a qualitative descriptive method with a case study approach. The research subjects were 25 students who were selected based on the criteria of various academic abilities and difficulties in problem solving. Data was collected through mathematical problem solving tests, semi-structured interviews, and observations. The research results showed that students' errors in solving mathematical problems were divided into three types, namely: conceptual errors (44%), procedural errors (36%), and calculation errors (20%). Conceptual errors occur due to students' lack of understanding of basic mathematical principles, such as fractional number operations. Procedural errors are caused by students' ignorance in determining systematic steps to solve problems. Meanwhile, calculation errors arise due to students' low accuracy and concentration. This research recommends using a problem-based learning approach and interactive media to increase students' understanding of concepts. Apart from that, providing varied practice questions and feedback can help students correct their mistakes. Thus, students' mathematical problem solving abilities are expected to increase significantly.

Abstract

Learning the concepts of Greatest Common Factor (GCF) and Least Common Multiple (LCM) at the elementary school level faces significant challenges due to their abstract and complex nature. This study aims to develop and evaluate the effectiveness of innovative learning strategies using the congklak game in enhancing students' understanding of GCF and LCM concepts. The research employed a Research and Development (R&D) methodology with the ADDIE model, involving 14 fifth-grade students from SDS Nahdlatul Ulama Medan as research subjects. The congklak game was developed as an interactive learning tool that integrates traditional game elements with mathematical concepts. Implementation was conducted through structured phases including needs analysis, media design, prototype development, learning implementation, and outcome evaluation. Research findings demonstrate significant improvements in students' conceptual understanding and learning outcomes. The use of congklak media successfully created contextual learning experiences that enabled students to visualize abstract GCF and LCM concepts through manipulation of congklak seeds. This strategy also increased active student engagement, promoted collaborative learning, and created an enjoyable learning atmosphere. Data analysis showed improved average student scores and higher learning mastery rates compared to conventional teaching methods. This study provides practical contributions to the development of mathematics teaching strategies at the elementary school level, particularly in teaching GCF and LCM concepts. The research findings recommend the use of congklak media as an effective alternative for enhancing the quality of meaningful mathematics learning oriented toward conceptual understanding.

Abstract

Exploration of ethnomathematics in the context of flat geometry, especially triangles, in traditional Batak Toba clothing, is an interesting and important study. This study aims to reveal the relationship between mathematical concepts and local culture, and how geometric elements can be found in the design of Sortopi traditional clothing. This research method uses a qualitative approach with data sources, namely library studies, from several literature reviews according to the topic and purpose of the study. The results of the study show that Sortopi is a complement to traditional Batak clothing used by men as a crown or headband. The shape of Sortopi contains elements of isosceles triangle flat geometry, thus showing that cultural elements are inseparable from mathematics.

Abstract

This study aims to examine the application of mathematical concepts, such as proportion, and symmetry, in traditional Batak house architecture through an ethnomathematics approach. The method used is a literature study, where data is obtained from various written sources, such as books, scientific journals, and related articles. The analysis was carried out by content analysis, namely by identifying and categorizing the main themes that appear in the literature, then synthesized to understand how Batak local wisdom reflects the application of mathematical concepts in the design and construction of traditional houses, especially Bolon houses. The results of the study indicate that the Batak people traditionally apply mathematical principles in creating strong, aesthetic, and symbolic building structures, and are relevant to their cultural values. This study reveals that the concept of ethnomathematics plays an important role in understanding the relationship between mathematics and local culture.

Abstract

This article, deep learning-based mathematics learning combined with interactive media is discussed to improve students' critical thinking skills in grade III. A systematic literature review (SLR) approach was applied to twenty scientific articles published between 2020 and 2020. The results showed that implementing deep learning encourages students to actively participate in the process of solving contextual problems, think critically, and understand concepts thoroughly. The use of interactive media such as digital simulations and educational games encourage students to be more engaged in learning and improve their understanding of complex mathematical concepts. However, major issues such as infrastructure shortages and teachers' lack of technological capabilities hinder implementation. This study found that cross-stakeholder collaboration and adaptive education system support are necessary for the success of this approach.

Abstract

This study discusses how to apply a deep learning approach to support mathematics learning in elementary schools. Where this study uses a qualitative method. This study obtains data from literature reviews, researchers examine various relevant national scientific sources to identify the benefits, challenges, and opportunities for integrating deep learning technology in mathematics learning. The results of the study show that the application of deep learning to mathematics studies has a positive impact on student understanding. This method encourages active student involvement through various interactive activities, such as simulations and experiments, so that the learning process becomes more meaningful and enjoyable. However, the application of this method is also faced with a number of challenges, such as limited time to complete the curriculum and unequal access to technology among students.
