Good study habits are an important factor in achieving success in elementary school learning. However, based on observations in class 3 of SDN 1 Bugel, it was found that students still show less disciplined behavior during the learning process, especially during group activities, such as talking without permission, not paying attention, and not following classroom rules. This study aims to improve students' study discipline in grade 3 of SDN 1 Bugel by using the Star Rewards system within the cooperative learning model called Numbered Heads Together (NHT). This study uses the Classroom Action Research (PTK) approach with a two-cycle design following the Kemmis and McTaggart model. The research subject is 17 third-grade students from SDN 1 Bugel. Data collection was done through observation, questionnaires, documentation, field notes, and interviews. Data analysis was done using both quantitative and qualitative descriptive techniques. The research results show that using the Star Rewards system in cooperative learning type NHT has significantly improved students' discipline in studying. The average score on the discipline questionnaire increased from 69.5 in cycle I to 85.5 in cycle II, showing an increase of 16.03 points. The minimum score for students has gone up from 50 to 75, showing that all students have improved in terms of discipline. Giving positive reinforcement through stars has been proven to motivate students to be more disciplined, focused, and responsible during learning. This finding suggests that combining the NHT model with the Star Rewards system can be an effective strategy for helping build discipline in elementary school students.

This study aims to describe Sundanese language learning discourse in the eleventh grade at SMA Negeri 8 Bandung city based on the components of learning discourse. The study employed a qualitative approach with a descriptive method. Data were collected through observation using the non-participatory observation method (SBLC) and recording techniques. The data consisted of recorded utterances during Sundanese language learning activities, which were then transcribed into written form. Data analysis was conducted using content analysis and hermeneutic techniques. The results showed that the learning process consisted of opening, core, and closing activities using the Cooperative Learning model. The components of learning discourse identified included opening and closing conversations, participant cooperation, speech acts, and the nature of utterance sequences. The interaction demonstrated the use of quantity and quality maxims, locutionary, illocutionary, and perlocutionary speech acts, as well as chained utterance sequences in the form of question-and-answer interactions between teacher and students. The findings also revealed that the learning process tended to be teacher-centered, as the teacher was more dominant in directing classroom interaction, although the communication remained interactive and supported the achievement of learning objectives.

This article examines the use of cooperative learning strategies in Christian Religious Education (CRE) as an instructional approach that emphasizes the strengthening of students’ faith and Christian character. The discussion covers the definition, objectives, conceptual foundations, principles, and operational procedures of cooperative learning, which are then connected to the theological goals of CRE. The study employs a qualitative approach using a library research method, analyzing pedagogical and theological literature to construct a conceptual framework for implementing cooperative learning within the context of CRE. The findings indicate that cooperative learning strategies are highly aligned with the essence of CRE, as they foster dialogical interaction, shared responsibility, empathy, and the internalization of Gospel values through collaborative learning processes. The effective implementation of this strategy can create a participatory, reflective, and formative learning community that enhances not only cognitive understanding but also students’ attitudes, spirituality, and Christian character. This research is significant in providing both theoretical and practical foundations for CRE educators in designing learning experiences that are relevant, relational, and transformative in accordance with the goals of faith formation.

Students’ low critical thinking skills in mathematics remain a persistent issue, largely due to teacher-centered instructional practices that limit student participation and hinder deep conceptual understanding. To address this problem, a more engaging learning approach is required, such as the Student Teams Achievement Divisions (STAD) cooperative learning model. This study aims to examine whether students taught using the STAD model demonstrate higher critical thinking abilities than those taught through direct instruction in social arithmetic topics. The research employed an experimental method with a quantitative approach, using a posttest-only control group design. The sample consisted of two classes: an experimental group and a control group. Data were collected through essay-based tests designed to measure students’ critical thinking skills. The analysis involved prerequisite testing and hypothesis testing using an independent sample t-test. The findings revealed that the calculated t-value (2.033) exceeded the t-table value (2.00958) at a 0.05 significance level, indicating a significant difference. Therefore, the STAD model proves more effective in enhancing students’ critical thinking skills.

Student cooperatives in Islamic boarding schools are no longer merely understood as business units providing daily necessities, but have developed into socio-economic spaces that shape independence, trust, and Islamic entrepreneurship education among students. This study is motivated by the limited number of studies examining pesantren cooperatives as socio-religious processes that cultivate values of trustworthiness, responsibility, transparency, and cooperation in students’ daily lives. The study aims to explain the empirical practices of student involvement in cooperative management, the social relations formed through economic activities in pesantren, and their implications for Islamic entrepreneurship education and the strengthening of pesantren economic independence. This research employed a qualitative approach with a field study method conducted at Pondok Pesantren Modern Elfira 2 Purwokerto. Data were collected through observation, interviews with cooperative administrators and student managers, and documentation of financial reports and cooperative operational activities. The findings reveal that students are directly involved in managing goods inventory, customer service, digital financial recording, and the distribution of daily necessities within the pesantren environment. These practices foster values of trustworthiness, transparency, responsibility, and cooperation through supervision systems, work shift arrangements, and daily evaluations. In addition to strengthening the pesantren’s economy, the cooperative also functions as a medium for experiential Islamic entrepreneurship learning. This article contributes to the sociology of Islamic education by demonstrating that student cooperatives function as socio-economic laboratories that shape students’ independence, social trust, and Islamic entrepreneurial ethics within the everyday life of pesantren communities.

The development of fine motor skills and collaborative character is an essential foundation during the golden age period to support children’s academic readiness and social development.

The study concludes that Straw Connectorsmedia is effective in improving visual-motor coordination, creativity, and collaborative skills while fostering social empathy through interdependent interaction among children during the learning process.

In multilingual English as a Foreign Language (EFL) classrooms, students often draw on multiple linguistic resources to support comprehension and interaction during collaborative learning activities. However, translanguaging practices within structured cooperative learning techniques, such as the Jigsaw method, remain underexplored in Indonesian higher education contexts. This study investigates how students employ translanguaging during Jigsaw-based collaborative activities and how they perceive its role in supporting their participation and understanding in an Indonesian EFL classroom. The study adopted a qualitative classroom-based case study design conducted at a pesantren-based university in East Java, Indonesia. Data were collected through semi-structured interviews with five fifth-semester students who participated in Jigsaw learning activities across different English-related courses. The data were analyzed using thematic analysis to identify patterns in students’ language practices and perceptions. The findings reveal that translanguaging played several important roles in facilitating collaborative learning. First, students used translanguaging to clarify complex concepts and ensure shared understanding during group discussions. Second, translanguaging functioned as peer scaffolding, enabling students to assist classmates by explaining ideas and translating unfamiliar terms. Third, the flexible use of multiple languages helped reduce anxiety and encouraged more active participation in group interaction. Finally, students expressed positive perceptions toward translanguaging, viewing it as a helpful strategy that supported comprehension while still maintaining the importance of English for academic communication. These findings suggest that integrating translanguaging into cooperative learning strategies such as the Jigsaw technique can create more inclusive and interactive learning environments in multilingual EFL classrooms.

Group-based learning in the classroom plays a vital role in enhancing social interaction, individual responsibility, as well as students' critical thinking and collaborative skills. However, its implementation often faces challenges such as the dominance of certain members, social loafing, low participation, and interpersonal conflicts that hinder group effectiveness. This study aims to comprehensively examine the dynamics of learning groups by integrating four key aspects: the concept of group dynamics based on the Tuckman model, the characteristics of effective groups in cooperative learning, group formation techniques, and conflict management strategies. The research utilizes a qualitative approach with a literature study method, analyzing 25 sources including nationally accredited journals, academic books, and theses published between 2020 and 2024. Data analysis was conducted through reduction, thematic classification, content analysis, and conceptual synthesis. The results indicate that effective group dynamics can be achieved through the Tuckman stages, the application of the five elements of cooperative learning, the selection of appropriate group formation techniques with risk mitigation, and the implementation of the Thomas-Kilmann conflict management styles.The scientific contribution of this research is the development of an integrative model based on these four aspects, which serves as a conceptual framework to strengthen collaborative learning practices in the classroom. Practical implications include the formation of ideal groups consisting of 4–5 students, the establishment of initial group contracts, the use of dual assessment rubrics (individual and group), and peer evaluation mechanisms to enhance accountability and reflection.

This study aims to analyze the strategies of multicultural Islamic Religious Education (PAI) learning in fostering students’ tolerance attitudes in the context of Indonesia’s diverse society. This research employs a qualitative approach using a library research method by examining various relevant scientific literatures, including journals, books, and policy documents. Data were analyzed through stages of data collection, reduction, thematic analysis, and synthesis. The findings indicate that there are three main strategies in implementing multicultural-based PAI learning: (1) enrichment of teaching materials with multicultural perspectives, (2) application of dialogic discussion and cooperative learning methods, and (3) creation of a democratic and inclusive school culture. These strategies are proven to significantly contribute to the development of students’ tolerance, inclusivity, and respect for diversity. However, several challenges are identified, such as limited teacher competence, lack of inclusive teaching materials, social pressures, and the influence of digital media. In conclusion, multicultural-based PAI learning plays a crucial role in shaping tolerant and inclusive students. Its successful implementation requires a holistic, adaptive, and collaborative approach involving curriculum development, teacher competence enhancement, and support from the broader educational ecosystem.

This study examines the pedagogical transformation of Islamic Religious Education (PAI) teachers in realizing gender-equitable and inclusive learning. Ideal PAI teacher pedagogy encompasses not only content mastery but also pedagogical competence and social sensitivity capable of responding fairly to learner diversity. This study identifies that traditional teacher-centered, rote-oriented pedagogy with minimal gender awareness constitutes a primary barrier to creating equitable learning environments. The required transformation includes developing cooperative learning strategies, eliminating gender bias in classroom interactions, differentiating instruction according to student needs, and using inclusive stereotype-free teaching materials. The theological foundation of Islam affirms that human dignity regardless of gender as emphasized in QS. Al-Hujurat: 13 aligns with inclusivity values in education, making this transformation an authentic manifestation of the rahmatan lil'alamin principle rather than a deviation from Islamic values. Despite ongoing challenges including entrenched patriarchal culture, limited gender literacy, insufficient inclusive teaching materials, and social resistance, this pedagogical transformation carries broad implications for improving learning quality, strengthening tolerance, and enhancing PAI teacher professionalism in Indonesia.

 Education in the 21st century demands a paradigm shift from passive learning to collaborative and student-centered learning, in line with the Merdeka Curriculum’s emphasis on the value of mutual cooperation. However, challenges arise due to the younger generation’s heavy reliance on technology, which tends to foster individualism. This study aims to examine the implementation of cooperative learning strategies as a solution to foster social interaction and student engagement. Cooperative learning strategies constitute a conceptual framework for a series of learning activities within heterogeneous small groups to achieve shared goals. Through a literature review, it was found that the implementation of these strategies involves systematic steps ranging from group formation, problem-solving discussions, to group recognition. The results of the analysis indicate that cooperative strategies have significant advantages in enhancing students’ self-confidence, independence, responsibility, and academic achievement. Although they have limitations regarding time management and the need for specific skills among educators, these strategies are considered highly relevant for fostering students’ character to be inclusive, tolerant, and capable of collaborating amidst differences.

The retention of customers in the retail banking sector is a critical economic imperative; however, predictive modeling is frequently hindered by severe class imbalance and the “Black Box” nature of complex algorithms. This study proposes a Heterogeneous Stacking Ensemble framework integrating XGBoost, CatBoost, and Random Forest base learners with a Logistic Regression meta-learner to forecast customer attrition. To overcome the pervasive “Majority Class Bias,” we introduce a “Dual-Imbalance Defense” that synergizes the Synthetic Minority Over-sampling Technique (SMOTE) with algorithmic cost-sensitive penalization. Furthermore, moving beyond standard accuracy metrics, the framework mathematically derives a dynamic classification threshold to guarantee a strict 0.90 recall rate, actively optimizing the capture of at-risk capital. Model opacity is addressed through the integration of a SHapley Additive exPlanations (SHAP) TreeExplainer. This cooperative game theory approach provides localized, patient-level “Reason Codes” for regulatory compliance and reveals global systemic vulnerabilities, including non-linear drivers such as the “Product Paradox.” Achieving a 0.90 recall rate and an AUC of 0.8654, this framework provides a statistically robust and operationally transparent tool for targeted customer retention.

This research aims to describe the application of the Jigsaw learning method in increasing students' interest in learning in Catholic Religious Education. This research is based on the fact that the application of monotonous teaching methods tends to result in low student engagement in the learning process, which in turn affects their interest in learning. In this context, the Jigsaw method is viewed as one of the cooperative learning alternatives that can encourage students learn actively, responsibly, and collaboratively in groups. In this study, a qualitative descriptive approach was used through a literature review. Data were obtained through the study various relevant bibliographic sources, and then analysed descriptively through the stages of collection, selection, classification, interpretation, and conclusion drawing. The research shows that the Jigsaw learning method can increase students' interest in learning, as this method encourages students to be more active in the learning process, more responsible in understanding and conveying the material, and more capable of collaborating with their peers. The Jigsaw method also contributes to the creation of a more dynamic, participatory, and meaningful learning atmosphere. Therefore, the Jigsaw learning method is a strategic alternative that should be implemented to improve the quality of Catholic Religious Education.

Learning media is a tool that can be used to help students learn better and more efficiently. The media used in SMP Negeri 23 Pekanbaru is a teacher-centered picture/poster media so that students quickly get bored, and because of the limited media from the school. Most students prefer learning that involves them directly such as the element of games. The learning models used are discovery, PBL, and lecture models, and student learning activities are still lacking or less active in science learning. The purpose of this study is to develop learning media in the form of a cooperative-based snakes and ladders game with the Teams Games Tournament (TGT) type which aims to train student learning activities. The research method used is Research and Development (R&D) by implementing the ADDIE model which consists of five stages, namely Analyze, Design, Development, Implement, and Evaluation. Based on the validation results obtained, media experts were 94% with very feasible criteria, material experts were 92% with very feasible criteria, teachers gave a practicality assessment of 95% with very practical criteria, and students' responses were 85% with very interested criteria. This shows that the snakes and ladders media based on Teams Games Tournament (TGT) is very reasonable, very practical to use, and very interesting for students during the learning process. The results of observations on all student learning activities showed that 79% got a good interpretation.
