However, previous studies have shown that students' spatial abilities in geometry are still low. This is due to teachers' lack of appropriate teaching models and the insufficient utilization of technological learning media. The primary objective of this study is to determine the difference in spatial abilities between students who received the Contextual Teaching and Learning (CTL) model assisted by Math City Maps and those who received conventional learning. The research method used in this study is quantitative, with a quasi-experimental method. The design employed is a pretest-posttest control group design. The study results indicate a significant improvement in students' spatial abilities. This is evident from the calculation results, where the t-test results show a Sig. (2-tailed) value of 0.000 < 0.05, leading to the conclusion that the Contextual Teaching and Learning model assisted by Math City Maps has an impact on students' spatial abilities.

Abstract

The conceptual understanding of comparative mathematics remains a significant challenge in elementary education, as students rely heavily on formulaic approaches rather than developing deeper comprehension. This condition highlights the importance of the role of teachers in assisting with learning methods such as scaffolding. This study aims to analyze the efficiency of the scaffolding method in improving students' cognitive aspects. Scaffolding can help students improve mathematics learning outcomes and mathematical problem-solving skills and improve the cognitive aspect applied to grade V students in one of the state elementary schools in the Pondok Kacang area. This study uses a descriptive qualitative approach with data collection through observation, interviews, and documentation with data sources of a teacher and 3 grade V students in one of the State Elementary Schools in the Pondok Kacang area. The results of the study on the application of the scaffolding method to improving cognitive aspects in students in the context of learning mathematics ratio materials show that the application of the scaffolding method is efficient and effective; this can be seen from the improvement of students' cognitive aspects through assisting children in the early stages of their development, applying a multi-level approach, and efforts to follow the characteristics of scaffolding when there is an argument between students and teachers. The scaffolding method improves students' cognitive aspects by using motivational strategies and associating students' interests with learning assignments. Therefore, the scaffolding method plays a role in developing students' cognitive skills, especially in mathematics

Abstract

The current mathematics learning process has not fully succeeded in incorporating project-based modules. The Independent Curriculum emphasizes the use of Project-Based Learning (PjBL), where students engage in real-world projects to solve problems or answer specific questions. This approach aims to foster critical thinking, collaboration, and creativity among students. This study focuses on implementing a project-based statistical spatial module tailored for elementary school students. The research utilized qualitative methods, involving a population of 15 fifth-grade students from an Islamic Elementary School in South Jakarta. Data collection techniques included observation and testing. The application of PjBL made mathematics learning more engaging and meaningful. The projects designed not only enhanced students' curiosity but also provided opportunities to develop their creativity, critical thinking, and teamwork skills. Through this approach, students not only gain mathematical knowledge but also cultivate essential skills for their present and future lives.
