Instilling the value of unity from an early age is essential in shaping a young generation with tolerance and the ability to live harmoniously in diversity. However, the teaching of Pancasila in elementary schools is still largely carried out through conventional approaches that inadequately address students’ affective development. Instruction often remains teacher-centered and lacks interaction, making it difficult for students to internalize national values in their daily lives. This study aims to examine the effectiveness of implementing the Think Pair Share (TPS) model in enhancing students’ understanding of the value of unity in sixth-grade Pancasila education. The research employed a qualitative approach using a literature review method. Data were collected from scholarly journals, books, and relevant studies published between 2020 and 2025. The data were analyzed using content analysis techniques to explore the patterns of TPS implementation and its impact on students’ comprehension of unity. The findings reveal that the TPS model fosters a collaborative, inclusive, and participatory learning environment, enabling students to grasp and internalize the value of unity more deeply. The stages of TPS—thinking, pairing, and sharing—provide students with opportunities to express opinions, listen to others' perspectives, and reach shared understanding. In addition to improving academic outcomes, this model also significantly contributes to the development of character and social attitudes. In conclusion, the TPS model is an effective and relevant teaching strategy for instilling Pancasila values, particularly unity, within the context of 21st-century learning and the Merdeka Curriculum, which emphasizes active, contextual, and character-based education.

This study aims to analyze the impact of the Problem Based Learning (PBL) model on the learning outcomes of intellectually disabled 11th-grade students at SLB Negeri Sukapura, Kiaracondong District, Bandung City, in science subjects. The study involved two students with IQ ranges between 40-67. A collaborative approach was used, involving researchers and teachers to observe students' activities during problem-based learning sessions. Data were collected through observations, interviews, and learning outcome tests. The results indicated that implementing PBL positively influenced students' engagement and understanding, particularly among students with higher IQs. However, challenges persisted for students with lower IQs, requiring adjusted teaching methods for greater effectiveness. The application of PBL demonstrated an average improvement in learning outcomes, although some students did not meet the minimum mastery criteria. This study suggests further enhancements in the implementation of PBL to optimize learning experiences for intellectually disabled students.

Learning the concepts of Greatest Common Factor (GCF) and Least Common Multiple (LCM) at the elementary school level faces significant challenges due to their abstract and complex nature. This study aims to develop and evaluate the effectiveness of innovative learning strategies using the congklak game in enhancing students' understanding of GCF and LCM concepts. The research employed a Research and Development (R&D) methodology with the ADDIE model, involving 14 fifth-grade students from SDS Nahdlatul Ulama Medan as research subjects. The congklak game was developed as an interactive learning tool that integrates traditional game elements with mathematical concepts. Implementation was conducted through structured phases including needs analysis, media design, prototype development, learning implementation, and outcome evaluation. Research findings demonstrate significant improvements in students' conceptual understanding and learning outcomes. The use of congklak media successfully created contextual learning experiences that enabled students to visualize abstract GCF and LCM concepts through manipulation of congklak seeds. This strategy also increased active student engagement, promoted collaborative learning, and created an enjoyable learning atmosphere. Data analysis showed improved average student scores and higher learning mastery rates compared to conventional teaching methods. This study provides practical contributions to the development of mathematics teaching strategies at the elementary school level, particularly in teaching GCF and LCM concepts. The research findings recommend the use of congklak media as an effective alternative for enhancing the quality of meaningful mathematics learning oriented toward conceptual understanding.

This study aims to improve the learning outcomes of students in class IV-A in IPAS subjects, especially on the material of friction and muscle force, by using the Problem Based Learning (PBL) Learning Model at SDN Pakis 1 Surabaya. This research is a Classroom Action Research (PTK) conducted in two cycles, each of which consists of planning, implementation, observation, and reflection stages. The subjects of this study were 28 students of class IV-A. The instruments used include learning outcome tests to measure students' understanding of the material taught. The results showed a significant increase in student learning outcomes. At the pre-cycle stage, only 39% of students achieved mastery, while 61% of students were not yet complete. After the implementation of PBL, in cycle 1 student completeness increased to 71%, and in cycle 2 all students reached completeness with a percentage of 100%. PBL proved to be effective in improving students' understanding of the concepts of friction and muscle force through problem solving that is relevant to everyday life. Thus, the application of Problem Based Learning (PBL) can significantly improve student learning outcomes in IPAS subjects, especially in understanding abstract concepts such as force. This method is also effective in developing students' critical and collaborative thinking skills.  

This Classroom Action Research aimed to enhance the mathematics learning outcomes of fourth-grade students at SDN Pakis 01 Surabaya in understanding the multiplication of whole numbers up to 100. The study involved 27 students. Data was collected through observation, tests, and documentation. The cooperative learning model, Teams Games Tournament (TGT), was implemented. Results indicated a significant improvement in students' mathematics achievement, particularly in multiplication, following the implementation of TGT. The percentage of students achieving mastery increased from 37.04% in the pre-cycle to 85.19% in Cycle II. This substantial improvement suggests that TGT effectively created an active, collaborative, and engaging learning environment, motivating students to participate more actively in the learning process. Furthermore, there was a notable increase in the class average across cycles. The implementation of TGT successfully achieved the research objective of enhancing students' understanding of the multiplication concept. Therefore, it is recommended that the TGT model be considered as an alternative to improve the quality of mathematics education in elementary schools.    

The Think Pair Share cooperative learning technique is highly effective in fostering diverse discussion patterns. The purpose of Think Pair Share learning is to shape student interaction habits. The Think Pair Share instructional approach provides students with extended opportunities for reflection, articulation, and collaborative assistance. The objective of this study is to enhance the academic performance of students in class X viral material at SMA Negeri 2 Tondano by applying the Think Pair Share instructional approach. The research methodology employed is known as Classroom Action Research (PTK), which is conducted in two cycles, with each cycle comprising four distinct stages: preparation, implementation/action, observation, and reflection. The research findings indicate that the implementation of the Think Pair Share (TPS) instructional approach has resulted in a significant enhancement of student learning outcomes in class 86.66% during cycle II. This indicates that the research findings have met the success criterion, specifically, that at least 75% of students have successfully finished.
