This study aims to enhance students' learning outcomes in Natural Science (IPA) through the demonstration method in fourth-grade students at SD Inpres Teas, Noebeba District, Timor Tengah Selatan Regency. The research was motivated by low science learning outcomes, with 60% of students failing to meet the Minimum Competency Criteria (KKM) of 70. Conventional teaching methods contributed to students' passivity and lack of engagement. This Classroom Action Research (CAR) follows the Kemmis and McTaggart model, consisting of two cycles with four stages: planning, implementation, observation, and reflection. The study involved 10 fourth-grade students, with data collected through learning outcome tests, observations, and teacher interviews. Descriptive quantitative analysis compared student performance before and after intervention. Results indicated that the demonstration method effectively improved science learning outcomes. Initially, students scored an average of 73.5, with a mastery rate of 40%. After applying the demonstration method in cycle I, the average increased to 84.1, with 70% mastery. In cycle II, refining teaching strategies led to an average score of 90.1, with 90% mastery. The method also enhanced student engagement, teamwork, and conceptual understanding. These findings suggest that the demonstration method is an effective strategy for improving science learning outcomes. Teachers are encouraged to incorporate demonstrations regularly, and schools should provide necessary resources to optimize learning experiences.

Science learning at school places greater emphasis on mastering basic scientific work abilities or science process skills, so that learning is more meaningful. However, based on observations made by researchers through field observations of the reality of science learning that takes place in class IV UPTD SD NEGERI 017973 KISARAN KOTA, it shows that there are still weaknesses in the science learning process which results in a decline in student learning outcomes. The weakness of science learning found in class IV UPTD SD NEGERI 017973 KISARAN KOTA is that this learning places more emphasis on mastering a number of facts and concepts, but does not facilitate students to obtain comprehensive and meaningful learning outcomes. The high percentage of students who have not been able to achieve the minimum completeness criteria, namely 36% indicated that the completeness of students' classical learning outcomes in this class was still not optimal so it needed to be improved. This research aims to improve the learning outcomes of class IV UPTD SD NEGERI 017973 KISARAN KOTA students by using the demonstration method in science learning.

This research aims to improve the science and science learning outcomes of class IV students at SDN 1 Pokak academic year 2023/2024. This research uses the Classroom Action Research (PTK) method which uses the Kemmis and Taggart model. The subjects of this research were class IV students at SDN 1 Pokak, totaling 14 participants educate. 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 mathematics learning outcomes for class IV students at SDN 1 Pokak. This increase was proven by the results of the pre-cycle test, the class average value was 72.5, then it increased in cycle I to 82.5 and increased again in cycle II to 85.7.    

This classroom action research was carried out to improve the learning process which was not yet optimal and the low learning outcomes in class V of SD Negeri Marga Cinta Kab. East Oku.  This research aims to evaluate the effect of applying the demonstration method on students' understanding and learning outcomes regarding science subjects regarding animal and human movement organs. Implementation of improvements was carried out in two cycles, namely Cycle I on 06 May 2022 and Cycle II on 08 May 2022. In Cycle I, there were several problems that arose during the learning process so that the expected goals were not achieved optimally. Only 63.6% of the student data obtained scores above the requirements for completeness or (KKM). However, in Cycle II, the learning process becomes more conducive and the expected goals can be achieved well. The demonstration method has succeeded in increasing students' enthusiasm, activeness and learning outcomes very satisfactorily, achieving a success percentage of 100%. This shows that the application of the demonstration method effectively increases students' understanding and learning outcomes in the science subject material on animal and human movement organs in class V of SD Negeri Marga Cinta Kab. East Oku. These results indicate that the demonstration method can be an effective alternative in improving student learning outcomes in animal and human movement organs.
