This article discusses the application of the Classroom Action Research (PTK) method with the Problem Based Learning (PBL) learning model to improve learning outcomes in measurement material in elementary schools. The PTK method is an effective approach in identifying learning problems, formulating solutions, and testing their effectiveness directly in the classroom. The PBL model, as a student-centered learning approach, has been proven effective in improving student learning outcomes in measurement material in elementary schools. In the context of measurement, the application of the PBL model is expected to strengthen students' understanding of basic measurement concepts, such as units of measurement, measuring tools, and their application in the context of everyday life. PBL offers a student-centered learning approach, which not only helps students understand mathematical concepts, but also encourages active involvement, problem solving, and the development of critical thinking skills.

The aim of this research is to find out the learning outcomes of students' Christian Religious Education and Character Education which are taught using the brainstorming method are higher than those taught using the problem solving method in class VII at SMP Negeri 1 Sipoholon in the 2023/2024 academic year. The method used in this research is true experimental design with posttest only control type. The population is all class VII students of SMP N 1 Sipoholon for the 2023/2024 academic year, totaling 189 people. The sample was determined using a purposive sampling technique of 62 people with conditions set in class VII-3 as the experimental class and class VII-4 as the control class. Data was collected with a test of 30 question items. The test data were analyzed using the separated variance t test formula according to the test analysis requirements, namely n1=n2 and the variance of the two sample groups was homogeneous. The results of hypothesis testing obtained a value of tcount = 11.13> ttable (α = 0.05; dk = n1+n2-2= 60) = ttable 1.671, so H₀ is rejected and H1 is accepted. Based on the research results, it can be seen that using the brainstorming method with an average learning achievement score of 8.26 is higher than using the problem solving method with an average score of 5.09 in class VII of SMP Negeri 1 Sipoholon for the 2023/2024 academic year.

Based on observations made by researchers in science learning in class VII of SMP Negeri 1 Simpang Teritip, there are still many weaknesses in the implementation of science learning. Teachers are less likely to involve students in the learning process, but teachers are more likely to use lectures that only require memory and memorization without developing insight into thinking and problem solving which allows students to learn more actively. The level of mastery of material by students is still low as evidenced by the learning results of 25 students with KKM (Material Completeness Criteria) > 75, there are 13 students or 55.56% of students who got a score below the KKM with a minimum score of 50. Based on the background that has been explained, then the problem formulation is obtained as follows. Can the use of the Discovery Learning model improve science learning outcomes regarding the interaction of living things with the environment for class VII students at SMP Negeri 1 Simpang Teritip? Implementation time for Strengthening Teaching Skills starts from March 28 2022 until 2022. June 5 2022 in the second semester of the 2021/2022 academic year. The results of Cycle 1 learning improvement showed the following results: 16 students got a score of less than 75, 11 students got a score greater than 75, and the student completion rate was 40.74%. In Cycle 2 there were 12 students who got a score less than 75, 15 students got a score greater than 75, and the student completion rate was 55.56%. In cycle 3, 2 students got a score less than 75, 25 students got a score greater than 75, and the student completion rate was 92.59%. The conclusion from writing this PTK is that the application of the recitation method using image media appropriately can improve learning outcomes.

The data analysis technique used is data analysis technique, namely data reduction, data display, and data verification. Based on student learning outcomes, it has not been achieved well. Judging from the data or student scores, it ranges from 75-79 with sufficient predicate, only a few students achieve 80-90, and from the data obtained by the school, 19 out of 33 students achieve sufficient predicate scores. with the average has not been reached to the maximum. Even then, the value of the learning outcomes has been assisted by carrying out remedial or repeat exams when student scores are problematic and assisted with plus values from the student's personality, therefore the authors conclude that PAI learning has not achieved maximum learning goals, so it needs stages or performance. maximum to improve learning outcomes so that learning is achieved properly. Then in terms of effective learning, some students have problems with interest or interest in PAI learning, therefore it has an impact on learning outcomes that are not achieved properly, and also has an impact on a child's attitude or behavior that is not good, such as behavior in daily life, such as every worship Zuhur students must be guided to carry out the worship not their own desires, then from a psychomotor point of view the children are still not well achieved that in the learning process there are some students with problem-solving skills such as not being active in discussions, not being fluent in reading Alqur'an skills and writing verses The Koran is blackboard.
