Numeracy is an important skill that elementary school students must have, but in reality it is still relatively low because learning tends to be conventional and less contextual. Numeracy does not only include the ability to count, but also the ability to understand, use, and interpret numbers and data in various daily life contexts. One of the causes of low student numeracy is a learning approach that is less interesting and not related to real situations. This study aims to test the effectiveness of the contextual learning model (Contextual Teaching and Learning/CTL) in improving students' mathematical numeracy skills. The research design used was a one-group pretest-posttest experiment with 23 fifth-grade students of SDN 002 Teluk Bintan as subjects. The instrument in the form of a numeracy test was given before and after the implementation of CTL, then the data were analyzed using prerequisite tests (normality and homogeneity) followed by a paired sample t-test. The results showed a significant increase in students' numeracy skills. The average pretest score of 24.78 increased to 73.91 in the posttest with a significance value of 0.000 <0.05. This increase proves that CTL is effective in helping students master numeracy through a learning process that links mathematical concepts with real experiences. Thus, the contextual learning model can be an alternative learning strategy that is relevant for increasing elementary school students' numeracy, while emphasizing the importance of implementing a more applicable approach in mathematics learning.

This study explores the alignment between science learning practices and children’s cognitive development stages based on Jean Piaget’s theory. Ten academic publications were systematically reviewed to examine how Piaget’s framework can be applied in science education. The findings highlight that integrating cognitive development theory is highly relevant for improving the quality of teaching and learning in schools. At the concrete operational stage (approximately 7–11 years), children learn best through direct experiences, manipulation of real objects, contextual media, and experiments that connect concepts with daily life. These methods help foster curiosity and reinforce conceptual understanding. As learners progress to the formal operational stage (around 11 years and above), they begin to think abstractly, reason logically, and analyze critically. At this level, student-centered approaches, inquiry-based methods, and constructivist learning become more effective in enhancing problem-solving, creativity, and higher-order thinking skills. The review also indicates that adapting instruction to developmental stages supports more meaningful and sustainable learning outcomes. In the Indonesian educational context, this approach can address challenges such as limited classroom facilities, diverse student learning styles, and a curriculum that is often overloaded. By applying Piaget’s insights, teachers can design learning strategies that bridge abstract concepts with concrete understanding, thus increasing student motivation and engagement. In conclusion, aligning science education with Piaget’s cognitive stages is an effective way to improve student performance and ensure long-term academic growth. The study provides valuable input for teachers, researchers, and policymakers in developing innovative, student-centered science and mathematics education.

This research is a development study that aims to create a product in the form of a learning aid, namely audio-visual media through the GeoGebra Classic application, which is used for 3-dimensional geometric shapes lessons in grade V of YPNU Elementary School Medan. This research was conducted because teachers still do not utilize technology optimally in teaching, especially in mathematics subjects related to spatial shapes. The lack of engaging and interactive teaching methods for complex topics like 3D geometric shapes often leads to reduced student interest and understanding. To improve the mathematics learning process on the topic of spatial shapes, audio-visual media was created with the help of the GeoGebra Classic 5 application. The goal is to provide variations in mathematics learning media and increase student interest in the lesson. The development of this media allows students to visualize 3D geometric shapes more clearly and interactively. The instrument used to collect data was a questionnaire that included questions to assess the effectiveness of the media from the perspective of educators and students. The results of the evaluation revealed that learning using this media received 93% responses from teachers and 87% from students, which indicates that the media is very effective. The positive feedback from both groups suggests that this audio-visual tool can enhance students' understanding of spatial geometry concepts and improve the overall learning experience. This study offers an innovative approach to teaching mathematics and highlights the importance of integrating technology into the classroom to foster better engagement and learning outcomes.

Mathematics is a universal science that underlies the development of modern science and technology, and has an important role in the development of human thinking. Mathematics is a subject that is based on logical, rational, critical, and systematic thinking patterns. Religion and rationality are two perspectives that have a strong influence. Humans view religious values ​​and rational values ​​as different entities, causing a dichotomy paradigm, especially in the realm of education. In the perspective of the epistemology of science in Islam, Islam and science are complementary and interdependent entities. The mathematical approach used here does not mean that Islamic values ​​are low, but only to increase the belief of Muslims that all knowledge is valuable and can lead to true goodness and increase faith and closeness to Allah SWT.To examine how Islamic values ​​are applied in mathematics learning, To identify and develop effective strategies or methods in integrating Islamic values ​​in mathematics learning materials, To measure the extent of the application of Islamic values ​​in mathematics learning.This study uses a qualitative approach, while the type of research used by the researcher is descriptive research.Mathematics as a logical and systematic science, has a meeting point with Islamic teachings that emphasize truth, justice, and balance. For example, the concept of monotheism can be associated with the order of the universe expressed through mathematical formulas, fostering a sense of gratitude and obedience. The implementation of Islamic values ​​that are rahmatan lil 'alamin (blessing for all nature) in mathematics learning, especially to form honest and fair characters in students.
