Students' activity in understanding the concept of ratio increased from 60.00% in cycle I to 90.00% in cycle II, while learning satisfaction based on questionnaires increased from 72.50% to 92.50%. The teacher's ability to implement PBL also developed from a fairly good category with a score of 1.9 to very good with a score of 3.24 in the first cycle and 3.9 in the second cycle. The final evaluation showed an increase in student learning completeness from 35.00% in the initial condition to 60.00% in the first cycle and 95.00% in the second cycle, with the average class increasing from 57.50 to 70.00 in the first cycle and 81.75 in the second cycle. These findings indicate that the PBL approach effectively improves student engagement and learning outcomes in understanding the concept of ratios.

This study aims to systematically examine various mathematics learning strategies based on deep learning approaches that can enhance elementary school students’ motivation and academic achievement. In the context of education, deep learning refers to learning processes that emphasize conceptual understanding, interrelated knowledge, and the development of critical and reflective thinking skills. Using the Systematic Literature Review (SLR) method, this research analyzes 20 relevant scholarly articles published between 2015 and 2024, sourced from leading databases such as Google Scholar. The review findings indicate that strategies such as problem-based learning (PBL), project-based learning (PJBL), metacognitive strategies, and the use of interactive learning technologies consistently improve student engagement, foster intrinsic motivation, and enhance mathematics learning outcomes. These findings suggest that integrating deep learning-based instructional strategies is highly relevant for elementary mathematics education, aiming to create more meaningful, student-centered learning experiences.

This study investigates the use of MATLAK (Mathematics Through Congklak) media in improving mathematics learning for class 5C students at SDN 067240 Medan Tembung. The objectives are to: (1) describe the application of MATLAK in the classroom, (2) determine its impact on students' mathematics learning outcomes, (3) analyze its effect on student motivation and engagement, and (4) assess the effectiveness of the traditional congklak game as a learning tool. Conducted as Classroom Action Research (CAR), this study aims to address classroom learning challenges through reflective cycles that enhance both teaching processes and student outcomes. The findings reveal that the integration of the Problem-Based Learning (PBL) model with MATLAK media, rooted in constructivist principles, significantly increased student activity and understanding, especially when problems presented were closely related to daily life. Students were encouraged to collaborate, think critically, and articulate their ideas during discussions. Additionally, student responses toward the use of MATLAK media were overwhelmingly positive, demonstrating increased motivation and active participation. Teacher observations also showed improvement in classroom engagement and implementation effectiveness from cycle I to cycle II. Overall, the study concludes that using the traditional congklak game as a mathematics learning medium when combined with the PBL model effectively enhances learning outcomes and student involvement in class 5C.

Education in elementary schools has the aim of helping students understand problems in everyday life. The national education system states that education aims to develop the potential of students to become human beings who have faith, noble character, health, knowledge and responsibility. In the context of mathematics education, the PMRI (Indonesian Realistic Mathematics Education) approach is used to help students understand mathematical concepts through real experiences and the context of everyday life. The data grouping learning trajectory using the PMRI approach aims to help grade 1 elementary school students understand the concept of data grouping. The use of sorting and choosing props can also improve the learning outcomes of low grade students in sorting and selecting certain objects or concepts. The aim of this research is that it is hoped that students can learn more effectively through direct experience, visualization and physical movements involved in the sorting and choosing process. Data was collected through interviews and tests. Based on the results and discussion of the research that has been conducted, it can be concluded that the design of a data grouping learning trajectory for elementary school students using an Indonesian realistic mathematics education approach is theoretically able to provide a deeper understanding of data grouping for grade I elementary school students. With the principles in PMRI, students are given the opportunity to develop a conceptual understanding of data grouping with the help of the images provided.
