This study aims to improve mathematics learning outcomes on addition and subtraction material through the use of elevator media in Grade 1 at SDN Pakahan in the 2024/2025 academic year. The problems encountered include low understanding of place value concepts, confusion in the borrowing and carrying process, and monotonous and less varied learning methods. The study employed a classroom action research approach conducted in two cycles, using both quantitative (pre-test and post-test) and qualitative (observation, interviews, and reflective journals) data collection techniques. The results showed an increase in the average student score from 72.2 initially, to 78.8 in the first cycle, and 88.4 in the second cycle, with a learning mastery rate reaching 100%. This improvement was influenced by the use of concrete learning media, increased student motivation, appropriate evaluation questions, and effective classroom management. Thus, the elevator media proved to be effective in enhancing students’ understanding and learning outcomes in basic arithmetic operations.

This research aims to improve the learning outcomes of grade 1 students at SD Negeri 2 Brangkal using the Discovery Learning learning model in the Pancasila Education subject. This research is divided into two images, where each cycle consists of four research stages, namely: 1) Planning, 2) Implementation, 3) Observation, and 4) Reflection. This research was conducted over a period of 3 months starting from February to April 2024. In this research the researcher acted as an observer by involving the class I Pancasila Education maple teacher as a colleague/collaborator. This Classroom Action Research (PTK) uses the Kemmis & Mc Taggart model. This research was carried out in two cycles where each cycle was held in one meeting. The subjects of this research were 18 grade 1 students at SD Negeri 2 Brangkal. Data collection techniques through evaluation tests, observation and documentation. The research results show that: (1) students become more active in learning activities. (2) there was an increase in Pancasila Education learning outcomes for grade 1 students at SD Negeri 2 Brangkal. This increase was proven by the results of the pre-cycle test, the average class score was 66.22, then it increased in cycle I to 82.5 and increased again in cycle II to 90.5. The percentage of completeness of learning outcomes in the pre-cycle was 40%, in cycle I was 75%, and in cycle II was 94% which achieved a KKTP ? 75. From the results of the above research it can be concluded that by implementing the Discovery Learning learning model it can improve learning outcomes in students.
