Mastery of science and technology is a must in facing the era of globalization. This requires various parties to be able to develop capabilities related to the development of capabilities in the field of technology. In the field of education, one of the educational breakthroughs in Indonesia that seeks to develop humans who can create a science and technology-based economy is STEAM (Science, Technology, Engineering, Arts, and Mathematics) learning. This study aims to describe STEAM as an alternative to learning mathematics in SD in the 21st century. This study uses a literature review method. The library study method is a critical study of the discussion of a topic that has been written by researchers or scientists in various sources in the form of books, journals, ebooks, or other scientific articles. The results of this study indicate that it is very important to use learning methods and media in the world of education to support teaching and learning activities, especially at the SD level. STEAM is one of the methods that can be used in learning but it is undeniable that this method cannot be applied in all school circles. Schools that have been able to use this method are those that are well-coordinated. Therefore, we really hope that this STEAM method can be implemented in all school circles which also indicates that our education is developing to be better every day.

This study aims to improve the understanding of the concept of plane figures in grade 2 elementary school students through a cognitive and psychomotor evaluation approach. The problem faced is the low understanding of students towards the characteristics and forms of plane figures, which has an impact on mathematics learning outcomes. The method used in this study is classroom action research (CAR) with two cycles, each consisting of planning, implementation, observation, and reflection. Cognitive evaluation is carried out through a written test that measures students' conceptual understanding, while psychomotor evaluation involves practical activities such as drawing and forming plane figures using simple tools. The results of the study showed a significant increase in students' understanding after intervention through both types of evaluation. Students became more active, enthusiastic, and able to connect abstract concepts with concrete activities. Thus, cognitive and psychomotor evaluations have proven effective in improving the understanding of plane figures in grade 2 elementary school students.    

Mathematical connection ability is a crucial competence that should be developed from the elementary level, as it helps students understand the interrelationships between mathematical concepts and their applications in daily life. This study aims to analyze the mathematical connection abilities of first-grade elementary school students in learning flat shapes. The research employed a descriptive quantitative method using cognitive and psychomotor assessment instruments. The cognitive test consisted of multiple-choice and essay questions measuring students' ability to recognize, understand, classify, and apply flat shapes. The psychomotor test involved tasks such as assembling flat shapes into meaningful objects and classifying shapes by type. The results showed that students were fairly capable of identifying and grouping flat shapes, but had difficulty explaining classification reasons or relating shapes to real-life objects. The psychomotor results also indicated that fine motor skills and the ability to make real-world connections need improvement. These findings highlight the importance of contextual learning approaches and the use of concrete media to strengthen students’ mathematical connections from an early age.    

Mathematics plays a crucial role in everyday life, as it enhances students' abilities to absorb lessons more effectively and develop rational, critical, logical, analytical, and systematic thinking. This study employs the literature review method, which involves gathering relevant information from various sources to support the research topic. The author collects references from articles and journals using Google Scholar, an open-access database that simplifies the process of locating topic-specific materials. Difficulties faced by students in learning mathematics are not always due to a lack of mathematical knowledge. They may stem from other issues such as memory problems, difficulty in recalling mathematical problems, weak calculation skills, confusion with operational signs, or reversing numbers. Students with learning disabilities may particularly struggle with both mathematical reasoning and basic computation. Furthermore, mathematical learning difficulties are also associated with cognitive challenges, such as solving complex word problems and understanding numerical concepts. These learning difficulties often result from internal and external factors that hinder the brain’s ability to process, analyze, and retain mathematical information effectively.

This study aims to analyze students' learning difficulties in solving mathematical story problems reviewed from the learning outcomes of fourth-grade students of SDN 117858 Teluk Binjai. This study uses a qualitative approach with a descriptive method. Data were collected through tests, interviews, and documentation involving teachers and students. The results of the study indicate that the main difficulties faced by students in solving mathematical story problems are low understanding of mathematical concepts, difficulty in interpreting information from story problems, and lack of ability to convert verbal information into mathematical forms. In addition, psychological factors such as anxiety and low self-confidence also affect students' performance in solving problems. Based on learning outcomes, students with lower grades tend to have more difficulty in understanding problems and applying solving strategies. These findings indicate the need for deeper pedagogical interventions to improve students' understanding of mathematical concepts and mathematical literacy skills, as well as emotional support to reduce anxiety related to mathematics.
