Economics education plays a crucial role in building students' understanding of managing limited resources, both on an individual and societal scale. However, isolated approaches to economics education often make it difficult for students to connect economic concepts with real life. This study aims to evaluate the effectiveness of integrating economics education with other subjects, such as mathematics, geography, and history, to create relevant and meaningful learning experiences. This approach aligns with the principles of the Kurikulum Merdeka, which emphasizes student-centered and life-relevant learning. This research employs the literature review method, involving the collection, analysis, and synthesis of information from various relevant sources, including books, journals, and scholarly articles. The findings indicate that integrating economics education can enhance students' conceptual understanding, analytical skills, and learning motivation. Moreover, this approach encourages students to recognize interdisciplinary connections, resulting in holistic comprehension. However, the implementation of such integration faces several challenges, including teacher readiness, time constraints, and limited supporting learning resources. Therefore, this study recommends the development of a more flexible curriculum, teacher training, and the creation of relevant teaching materials. The results are expected to provide insights for the development of innovative and holistic teaching methods in secondary education.

Computational ability is one of the basic skills that is very important for students in learning mathematics.

This study is founded on the issues identified, specifically the dearth of learning resources, the LKPD's lack of training in mathematical critical thinking, and the fact that the LKPD that is currently available was created by educators who did not follow a scientific methodology, which has led to students' low levels of mathematical critical thinking. In order to educate mathematical critical thinking skills in class VIII MTsS Asy-Syarif Koto Laweh for the 2023–2024 academic year, this project intends to produce LKPD based on a scientific approach that satisfies the requirements of validity, practicality, and effectiveness. Using Sugiyono's development paradigm, this study is called research and development, or R&D. Student answer surveys, mathematical critical thinking ability assessments, and validation sheets are the equipment. The techniques for data analysis that are employed are validity analysis, practicality analysis, analysis of effectiveness. Based on development study conducted, LKPD is obtained with a validity level of 84.2%, of which 82.33% are on extremely practical criteria, 78.94% are on effective criteria, and 82.33% are on highly valid criteria for the level of practicality. We may conclude that the LKPD Asy-Syarif Koto Laweh created, which is based on the Scientific Approach to Train Mathematical Critical Thinking Skills in Class VIII MTsS, satisfies the requirements of being valid, practical, and efficient.

This study aims to improve mathematics learning outcomes on probability material through the application of rotating wheel media in class 6A UPT SDN Kutorejo 1. Probability material is considered difficult by students because it is abstract and requires logical thinking skills. This study uses the PTK method with two cycles involving 29 students.

The learning process is the implementation of the curriculum in educational institutions to influence students to achieve predetermined goals. Lack of student enthusiasm in the learning process results in learning outcomes that are not optimal. The purpose of the study was to analyze the influencing factors and teacher strategies in improving the learning outcomes of fifth grade students in Mathematics at Al-Muhajirin Islamic Elementary School. The method used is qualitative. Data collection techniques with observation, interviews and documentation. The research findings show that student learning outcomes at Al-Muhajirin Islamic Elementary School are classified as good, but there are still students with low learning outcomes. This can be seen from the average score of the midterm exam which although it is quite satisfying, but there are students who have not reached the standard of completeness. The research conclusions include the supporting and inhibiting factors for student learning outcomes. Internal supporting factors include motivation and attitude, while external supporting factors come from relationships with parents, teachers and the environment. Meanwhile, internal inhibiting factors are motivation, intelligence, interest and talent, self-confidence, and discipline. External inhibiting factors include family, school and peer environment. The teacher's strategy in improving student learning outcomes is to provide motivation, use varied learning strategies, provide learning methods that are in accordance with the situation and conditions of students and use interesting learning media in accordance with learning materials.

Mathematical representative ability is a person's ability to express mathematical ideas, objects, and relationships in various forms of representation, both visually, symbolically, verbally, and contextually. This study aims to analyze the mathematical representative ability of students through counting operations in grade III elementary school in the form of story problems. The method used was descriptive qualitative research with written test instruments to assess cognitive abilities and observation to assess psychomotor skills. The research subjects consisted of five grade III elementary school students, by giving test questions on mathematical reasoning skills, observing students directly in solving and understanding story problems, conducting documentation to obtain accurate data when in the field by classifying students' mathematical representative abilities based on math scores. The results showed that most learners had a very good level of cognitive ability in completing arithmetic operations, but there were some learners who were still lacking in understanding story problems. This finding confirms that the importance of appropriate learning strategies so that learners are not only able to solve problems in the form of operations but also able to understand problems in the form of story problems that are applied in real life.
