This study aims to implement the Cooperative Integrated Reading and Composition (CIRC) learning model to improve collaboration skills and learning outcomes among phase E students in class X-3 at SMA Katolik 2 Kabanjahe in Catholic Religious Education. This research employed Classroom Action Research conducted in two cycles, consisting of planning, implementation, observation, and reflection stages. Data were collected through observation sheets, learning outcome tests, and documentation, then analyzed using descriptive qualitative analysis supported by process and learning achievement indicators. The findings showed that the implementation of the CIRC learning model improved across learning stages, including orientation from 87% to 95%, organization from 90% to 97%, concept introduction from 87% to 92%, publication from 93% to 98%, and reflection and reinforcement from 87% to 98%. Students’ collaboration skills also increased in each indicator, namely working productively from 75% to 88%, actively participating in problem solving from 82% to 88%, maintaining a balance between listening and speaking from 76% to 86%, appreciating group members’ contributions from 73% to 87%, and demonstrating responsibility as group members from 77% to 93%. Learning outcomes also improved, as shown by the increase in the proficient category from 27% to 77%, while the basic and developing categories decreased to 0% in cycle II. These results indicate that CIRC effectively enhances students’ active participation, collaboration, responsibility, and learning achievement. Therefore, CIRC is recommended as an alternative collaborative learning model for Catholic Religious Education, particularly in strengthening cooperative interaction and meaningful understanding of religious learning materials in classroom practice.

This study aims to improve students’ learning outcomes through the implementation of the cooperative learning model of Student Teams Achievement Division (STAD) in the Pancasila Education subject for class VIII A at SMP Muhammadiyah Singaraja. This research employed a Classroom Action Research (CAR) design conducted in two cycles. Each cycle consisted of four stages: planning, action, observation, and reflection. The research subjects were 29 students of class VIII A. Data were collected using learning achievement tests and observation sheets. The collected data were analyzed using descriptive quantitative techniques to evaluate students’ academic progress during each cycle. The findings indicate that the implementation of the STAD learning model contributed positively to improving students’ learning outcomes, participation, and engagement in classroom activities. Therefore, the STAD cooperative learning model can be considered an effective instructional strategy for enhancing learning achievement in Pancasila Education.

This study focuses on examining the effect of using the cooperative learning model type Teams Games Tournament (TGT) assisted by Kahoot in optimizing students’ problem-solving skills. The research method applied was Classroom Action Research (CAR), conducted through several cycles with stages including planning, action implementation, observation, and reflection. The subjects of this study were students of class X.B at SMA Negeri 2 Singaraja. The results of the study indicate a significant improvement in students’ problem-solving abilities after the implementation of the TGT model assisted by Kahoot. In cycle II, the students’ average score reached 88.15, with a learning mastery level of 84.21%. Therefore, it can be concluded that the majority of students had met the minimum learning mastery indicators. In addition, the learning process became more active, interactive, and enjoyable, which increased student engagement in the classroom. In conclusion, the cooperative learning model Teams Games Tournament (TGT) assisted by the Kahoot application has a positive impact on improving students’ problem-solving abilities. Therefore, the use of game-based digital learning models and media is recommended to enhance the quality of both the learning process and learning outcomes.

The current research examines the effect of the Student Teams Achievement Division (STAD) cooperative learning model on Indonesian language outcomes among sixth-grade students at SD Negeri 106805 Manunggal. Operating within a quantitative framework, this quasi-experimental research utilized a non-equivalent control group design. The sample comprised 50 students, classified into a control group (23 students) and an experimental group (27 students). Data collection involved observations, documentation, alongside pretest and posttest scores. The 10-item essayThe instrument achieved a high level of reliability, with Cronbach’s Alpha coefficients of 0.700 on the pretest and 0.807 on the posttest. Diagnostic tests confirmed the data were normal and homogeneous. The experimental group achieved a substantial learning improvement of 42.04, significantly outperforming the control group's gain of 17.39. The independent sample t-test yielded a critical significance value of 0.000 < 0.05, confirming that the STAD model exerts a significant and positive influence on student’s indonesian language achievement.

This study aims to determine the effectiveness of the implementation of cooperative learning methods on learning outcomes and students' understanding of Islamic Religious Education (IRE) subjects for Class VIII at MT Hubbul Wathon Sangatta Selatan. This study uses a quantitative method with a quasi-experimental research type using a non-equivalent control group design. The study population was 48 students of class VIII A and VIII B, with a sample size of 44 students, each class consisting of 22 students from the experimental class and the control class. Data collection techniques were carried out through tests (pre- and post-tests), observation, and recording. Data analysis used descriptive statistics, normality tests, homogeneity tests, N-Gain tests, and hypothesis tests (t-tests). The results showed that the average learning outcomes of students in the experimental class increased from 61.14% in the previous class to 84.09% in the next class, while in the control class increased from 63.41% to 77.73%. The results of the normality test showed that the data were normally distributed and the homogeneity test showed that the variances of the two groups were identical. The t-test results showed a significance value of 0.000 < 0.05, so it can be concluded that there is a significant difference between the experimental class and the control class. Thus, the cooperative learning method has a positive and effective effect in improving student learning outcomes and understanding in the Islamic Religious Education subject for Class VIII MT Hubbul Wathon Sangatta Selatan.

This classroom action research investigates the effectiveness of the Round Robin cooperative learning model in improving the motivation and creativity of learning science among Grade IV students at UPT SDN Unjuruiya No. 45, Selayar Islands. The study was conducted to address students’ low engagement, limited participation, and insufficient creative expression during IPAS lessons. The research involved 12 students (6 male and 6 female) and was implemented in two cycles, each consisting of three meetings—two for instructional activities and one for assessing learning creativity. Data were collected through observation, learning motivation assessments, and creativity evaluations. Findings indicate a significant improvement in student learning outcomes following the implementation of the Round Robin model. In Cycle I, only 5 students (42%) achieved the creative category, while 7 students (58%) remained in the non-creative category. However, after refinement and continued application in Cycle II, the number of students achieving the creative category increased substantially to 11 students (92%), leaving only 1 student (8%) in the non-creative category. These results demonstrate that the Round Robin model effectively enhances student motivation, encourages active participation, and supports the development of creativity in science learning. Overall, the study concludes that cooperative learning through Round Robin provides a meaningful and engaging instructional alternative capable of improving both motivational and creative learning aspects in elementary science classrooms.
