The results showed that the Team Games Tournament type cooperative learning model assisted by quizizz could improve student learning outcomes on the material of power numbers in class VIII SMP Negeri 21 Palu, by following the steps of the Team Games Tournament type cooperative learning model, namely: (1) class presentation, (2) learning in groups, (3) games, (4) tournament, and (5) team recognition. The results of the end-of-action test showed that in cycle I it was seen that students were still difficult in solving the problems given so that there were some students who could not solve the problem and there were students who still had difficulty in determining negative power numbers. Whereas in cycle II students had a better understanding of how to work on power numbers in determining the properties of power numbers. Based on the percentage of Classical Learning Completeness (KBK) in cycle I, it shows that students have difficulty in solving negative power number problems. This can be seen from the number of students who completed, namely out of 22 students who took the final test, there were only 14 students who got a complete score or got a score that reached the KKM of 75, so the percentage in cycle I only reached 63.63%. Whereas in cycle II shows that of the 17 students who took the final test, 16 students obtained a complete score or reached the KKM which is 75, so the percentage results in cycle II reached 93.11%. In addition, the results of observations of teacher activities in managing learning and student activities in participating in learning show an increase in each cycle. Based on the data from the research results, it can be concluded that the cooperative learning model of Team Games Tournament type assisted by quizizz can improve student learning outcomes on rank number material in class VIII SMP Negeri 21 Palu.

Differentiated learning is one of the learning approaches in the implementation of the Independent Curriculum (IKM). Discussions with the principal of SD Inpres 1 Tondo during the guidance of the 8th Batch of Teaching Campus Students (August-December 2024) revealed that most elementary school teachers in the Tondo sub-district were unable to develop differentiated teaching modules. This community service activity was held on September 1, 2025, at SD Inpres 1 Tondo. The training participants consisted of teachers from SD Inpres 1 Tondo, SD Inpres 2 Tondo, SD LIK Layana, and SD Alkhairat Tondo, with a total of 30 participants. This community service activity aimed to provide understanding and practical knowledge to the participants so they could design differentiated teaching modules. The training methods used were presentations, discussions, and mentoring. Data was collected by giving individual assignments to create differentiated teaching modules for a topic to be taught. The collected data was analyzed using percentage analysis. Observations and Q&A sessions during the training indicated that participants were highly enthusiastic about participating, and all participants understood how to develop differentiated teaching modules. Data analysis revealed that the average participant's ability to develop differentiated teaching modules was very good, with a score of 86.67.

This study aims to determine the level of students' ability in solving integer multiplication operations using the Lattice method at SMPN 6 Palu in grade VII. The type of research used in this study is descriptive research with a qualitative approach. The research data was collected through tests, observations, and interviews. The results of the study after using the Lattice method showed a difference in students' scores before and after using the Lattice method. Before using the lattice method, the average score of all students was only 62.3, but after using the lattice method, the average score of all students increased to 75.0. However, the increase was not significant, meaning not all students experienced it. It can be said that almost all students experienced difficulties in solving problems with varying error locations, such as students being less careful or considering the problem easy, students not understanding the concept of the problem, students not mastering multiplication operations or not memorizing multiplication, and finally, the lack of carefulness in students when working on problems.

This qualitative descriptive research aims to describe the mathematical connections of 9th-grade students at SMP Negeri 4 Sigi regarding spatial shapes based on their mathematical ability levels. Data were collected through written tests and interviews to explore students' understanding in depth. The results indicate that students with high mathematical ability are capable of connecting surface area with the area of a rectangle, converting diameter to radius in volume calculations, and systematically linking the concepts of area and volume. They can effectively apply mathematics to other disciplines and real-life contexts. Students with moderate ability demonstrate similar skills in connecting surface area, volume, and daily applications, yet they tend to be less specific in identifying interdisciplinary connections, such as with economics. Meanwhile, students with low ability are able to determine surface area and provide real-life examples, but they encounter difficulties in relating surface area to the concept of a rectangle's area and are unable to identify interdisciplinary relationships in written tests. Overall, there are significant differences in the depth of mathematical connections and systematic procedural abilities among the three groups of students in solving spatial shape problems.
