This research is classroom action research that aims to improve learning outcomes in Natural and Social Sciences (IPAS). The topic is changing forms of energy in class IV-B students, SDN Pakis 01 Surabaya. The number of students in the class consists of 25. The data collection method used consists of observation, tests, and documentation. The learning model applied is problem-based learning (PBL). The research results show that the learning model Problem-Based Learning (PBL) can significantly improve student learning outcomes in science subjects. The pre-cycle results showed a completion rate of 32%; in cycle 1, it increased to 56%, and then in cycle 2, it increased to 80%. Implementation of learning models (problem-based learning) has succeeded in achieving the expected targets and can effectively improve student learning outcomes, especially in class IV-B at SDN Pakis 1 Surabaya in the 2024-2025 academic year. The learning model of problem-based learning (PBL) is also known for its effectiveness in building students' critical thinking skills so that it can help make the learning process easier.
 
 

Students often have difficulty understanding the concepts of Natural and Social Sciences (IPAS), especially at the elementary school level. This difficulty is caused by the lack of variety of learning methods that are capable and attract students to actively participate in learning activities. The aim of this research is to determine the improvement in learning outcomes of class IV C students in the elastic movement material in science and science lessons. This research applies the Project Based Learning (PjBL) learning model which uses Mystery Box media. This research uses the Classroom Action Research (PTK) method which consists of two cycles. The instruments used include pretest and posttest as well as observation sheets. The data was analyzed descriptively quantitatively to measure the increase in learning outcomes from one cycle to the next. The research results show that implementing PjBL with Mystery Box media improves student learning outcomes. In the first cycle, there was significant improvement, although some students had not reached the target. In the second cycle, learning outcomes continued to improve, with the majority of students reaching or exceeding the KKM. The percentage obtained from the pretest and posttest results was from 56.73% to 74.62%.
 

This research aims to improve students' learning experience in Pancasila education through interactive video media at SDN 1 Pakis Surabaya. The research used a spiral-based PTK method with a total of 25 students, with a focus on planning, action, observation and reflection. The research results show a significant increase in,  student learning outcomes after video interactivity. This research shows that the use of interactive videos in the Pancasila education program at SDN 1 Pakis Surabaya significantly improves student learning outcomes. Based on the data collected, it appears that the use of interactive videos can improve students' understanding of the material, especially on teacher-led learning topics that prioritize good behavior in the surrounding environment. The increase in learning outcomes as seen from the average student score from 68 to 75 shows that this media is effective in helping students meet the Minimum Completion Criteria (KKM) that have been set. with a percentage in the initial condition of 41%, in cycle I which was proven to be 83%, and the percentage in cycle II was 100%. In addition, every student succeeded in achieving the learning objectives in cycle II, with a statistically significant average increase. Observations also showed that student activity and motivation increased, indicating that interactive videos had a positive impact on both academic performance and behavior.
 
 

The purpose of this classroom action research is to use the problem-based learning paradigm to improve the skills of twenty-four fourth-grade students at SDN Pakis 1 Surabaya in producing transitive and intransitive sentences. Methods such as observation, testing, and documentation were used to collect data. Two phases formed this investigation. Students of class IV A improved their learning outcomes for the formation of transitive and intransitive sentences according to the classroom action research. In cycle I, the average score was 72, or 45%, or 11 students. In cycle II, it jumped to 80, or 83%, or 20 students. This study found that in the 2024-2025 academic year, students in class IV A at SDN Pakis 1 Surabaya were able to improve their capacity to create transitive and intransitive sentences by using the problem-based learning paradigm. Problem-Based Learning is known as a learning method that involves identifying a problem and then assigning students to solve it, thus making students more active and able to understand the material during the learning process.
