The use of Search-Based Software Engineering (SBSE) for optimizing software architecture has evolved from fully automated to interactive approaches, integrating human expertise. However, current interactive tools face limitations: they typically support only single decision-makers, confine architects to passive roles, and induce significant cognitive fatigue from repetitive evaluations. These issues disconnect them from modern, team-based software development, where collaboration and consensus are crucial. To address these shortcomings, we propose "ArchEvolve," a novel framework designed to facilitate collaborative, multi-architect decision-making. ArchEvolve employs a cooperative coevolutionary model that concurrently evolves a population of candidate architectures and distinct populations representing each architect's unique preferences. This structure guides the search towards high-quality consensus solutions that accommodate diverse, often conflicting, stakeholder viewpoints. An integrated Artificial Neural Network (ANN) serves as a preference learning module, trained on explicit team feedback to act as a surrogate evaluator. This active learning cycle substantially reduces the number of required human interactions and alleviates user fatigue. Empirical evaluation on two industrial case studies (E-Commerce System and Healthcare Management System) compared ArchEvolve to a state-of-the-art interactive baseline. Results indicate that ArchEvolve achieves statistically significant improvements in both solution quality and consensus-building. The preference learning module demonstrated over 90% accuracy in predicting team ratings and reduced human evaluations by up to 46% without compromising final solution quality. ArchEvolve provides a practical, scalable framework supporting collaborative, consensus-driven architectural design, making interactive optimization a more viable and efficient tool for real-world software engineering teams by intelligently integrating cooperative coevolutionary search with a preference learning surrogate.

The purpose of this classroom action research is to improve students' ability to apply Indonesian language learning knowledge on short stories by implementing the Cooperative Integrated Reading and Composition model in grade IV of SDN 2 Manembo. The number of students in grade IV is 14 people. This research uses a classroom action research (CAR) method based on the inquiry learning method according to Kemmis and McTaggart (Aqib Zainal, 2016:64) and is implemented in two cycles. Each cycle consists of four stages, namely planning, action implementation, observation, and reflection. Qualitative data collection techniques are carried out through observation of learning activities, while quantitative data are collected from the results of LKPD. The data analysis technique uses the formula (Trianto, 2019:41) KB = T/Tt × 100%. Student learning outcomes in cycle I reached an average value of 70% with incomplete criteria, but increased in cycle II to 92% with complete criteria. In addition to improving learning abilities, students also feel more enthusiastic and active in participating in learning by implementing the Cooperative Integrated Reading and Composition model. It can be concluded that the implementation of the Cooperative Integrated Reading and Composition (CIRC) model can improve the reading comprehension skills of fourth-grade elementary school students.

This study aims to improve students' understanding of figurative language material through the application of the Bus Stop cooperative learning model combined with the Frayer Diagram media. The subjects of the study were sixth-grade students of Muhammadiyah 1 Bontang Elementary School. The method used was descriptive qualitative with observation, interview, and documentation techniques. The results of the study showed that the Bus Stop strategy encouraged active interaction between students, allowing them to discuss and provide feedback to each other. Meanwhile, the Frayer Diagram helped students map the concept of figurative language visually and systematically, thus facilitating their understanding of the four types of figurative language taught, namely personification, metaphor, hyperbole, and simile. The combination of these two methods proved effective, with 90% of students showing an increase in their ability to identify and construct figurative sentences. Based on these results, the study recommends the use of cooperative strategies combined with visual media as a more meaningful and enjoyable approach to learning Indonesian, and able to increase student engagement and understanding of figurative language material.

Education is a comprehensive process aimed at developing human quality, in which the success of learning largely depends on the implementation of appropriate instructional strategies. Learning strategies serve as a guide for educators in managing the interaction between teachers, learners, materials, and the learning environment to achieve educational goals effectively and efficiently. This study aims to describe the objectives of learning strategies in improving learning quality and to explain how relevant learning models can be applied based on students’ characteristics and learning contexts. This research employs a qualitative approach using a literature review method by analyzing various theories and previous studies related to learning strategies and educational quality improvement. The findings indicate that learning strategies play a central role in creating active, creative, and meaningful learning processes. The application of several models such as cooperative learning, inquiry learning, contextual teaching and learning, project-based learning, and discovery learning has been proven to enhance students’ motivation, engagement, and learning outcomes in cognitive, affective, and psychomotor domains. Therefore, systematically designed and adaptive learning strategies that focus on students’ potential are the key to improving learning quality and achieving comprehensive educational objectives.

This research addresses the low student learning outcomes and the lack of facilitation of 4C competencies (Critical Thinking, Collaboration, Communication, and Creativity) in the Industrial Machine Electrical Systems (SKMI) subject for Grade XI TMI 1 students at SMK Negeri 1 Pariaman. The teacher-centered learning approach has led to passive student participation, low critical thinking, varying academic abilities, and difficulty in connecting theoretical concepts to real-life applications. The aim of this study is to improve students' 4C competencies and learning outcomes through the implementation of the Team Assisted Individualization (TAI) cooperative learning model. Using Classroom Action Research (CAR) based on the Kemmis and McTaggart model, the study was conducted in three cycles: planning, implementation, observation, and reflection. The subjects were 30 students from Grade XI TMI 1. Data collection included learning outcome tests and 4C competency observation sheets, with descriptive and quantitative data analysis. The results showed significant improvements: classical mastery increased from 27% to 90%, average learning scores rose from 67 to 81, and 4C competency mastery improved from 34% (low) to 82% (high). The study concludes that the TAI model effectively enhances both 4C competencies and learning outcomes in SKMI at SMK Negeri 1 Pariaman.

This study aims to describe the characteristics of SMK Al-Azami students in emulating the morals of the Prophet Muhammad (peace be upon him) as part of character development based on Islamic values within vocational education. The background of this research lies in the urgency of character education that not only emphasizes academic competence and technical skills but also focuses on moral formation and professional ethics. This research employed a qualitative approach using a library research method by analyzing relevant classical and modern Islamic literature, supported by documentation of school activities. The results reveal that the moral values of the Prophet Muhammad have been well internalized in students’ daily behavior, which includes four core dimensions: Shidq (honesty), Amanah (trustworthiness), Istiqamah (discipline), and Rahmah (compassion). The value of Shidq is reflected in students’ honesty during vocational practice and in reporting work results; Amanah is demonstrated through responsibility for tools and group tasks; Istiqamah appears in punctuality, consistency, and work discipline; and Rahmah is shown through respectful, empathetic, and cooperative social interactions. The findings indicate that Islamic character education effectively shapes students with integrity, discipline, and social awareness, serving as a model for moral development in vocational schools. Furthermore, this research highlights the importance of strengthening teacher exemplarity, religious habituation, and curriculum integration of Islamic moral values in vocational learning to ensure sustainable character development.

The era of globalization is an era of quality competition, where only thosebwith high competence will be able to compete in the free market. Therefore, developing high-quality human resources is something that cannot be compromised. Education that supports development in this era is education that can foster students’ potential’ enabling them toface and overcome life’s challenges. Thus, in the learning process, teachers should not only serve as models or sources of knowledge but also act as learning managers. As learning managers, teachers play an important role in creating a learning environment that allows students to learn confortably and effectively. Based on observations at SMA Negeri 2 Taniwel, it was found that students in class X-2 have low learning outcomes in sociology. The writer’s observation in class indicated that sociology learning was dominated by lecture methods, resulting in students being less active during the learning process. According to research conducted by Al Muchtar (1991), learning in social studies education does not sufficiently simulate students to be actively involved in the learning process. Furthermore, the teaching and learning process of social studies carried out bye teachers has not been able to faster a learning culture among students, wich in turn significantly affects their learning achievement and outcomes. To support active learning strategies, teachers can apply various relevant learning models. Therefore, the learning process will become more varied, innovative, and constructive, creating interaction between teachers and students, among students themselves, and between students and other learning resources.

This study aims to determine the effect of applying the Jigsaw cooperative learning model on students’ literacy skills in the Indonesian language subject for sixth-grade students at SDN 76 Tarowang. The research employed a Quasi-Experimental Design with a Pretest–Posttest Design. The sample consisted of 17 students who participated in the learning process using the Jigsaw model. Data were collected through literacy skill tests administered before and after the treatment.The results showed that the average pretest score of 28.47 increased to 56.41 in the posttest, indicating an improvement of 27.94 points. The Shapiro–Wilk normality test confirmed that the data were normally distributed (pretest Sig. = 0.513; posttest Sig. = 0.336). Furthermore, the Paired Sample t-test revealed a t-value of 7.180 with a significance level (Sig. 2-tailed) = 0.000 (< 0.05), indicating a significant difference between pretest and posttest scores. These findings demonstrate that the implementation of the Jigsaw cooperative learning model has a significant positive effect on students’ literacy skills. This model effectively engages students in reading comprehension, summarizing information, and communicating ideas collaboratively.

This research is motivated by the low cognitive abilities of students in science learning in elementary schools, which is largely caused by conventional teaching methods that do not actively involve students. To overcome this problem, the Team Assisted Individually (TAI) learning model is used, which combines a cooperative approach and individual learning to improve the understanding of science concepts more effectively. The purpose of this study is to determine the effect of the TAI model on the cognitive abilities of fifth-grade students of SD Islam Baitul Salam Ciledug on natural phenomena material. This study uses a quantitative approach with a quasi-experimental design and a pretest-posttest control group design technique. The sample consists of two classes, namely the experimental class that uses the TAI model and the control class that uses conventional learning methods. The results of the study show that there is a significant increase in the cognitive learning outcomes of students who participate in learning with the TAI model compared to the conventional method. Therefore, this study is expected to provide an alternative effective learning model for teachers, as well as improve the quality of the process and student learning outcomes, especially in science learning.  

This study aims to examine the implementation of the cooperative learning model Think Pair Share (TPS) in improving students’ learning outcomes in Arabic language learning at Pesantren Paqusatta, as well as to identify the supporting and inhibiting factors in its application. This research employs a qualitative descriptive method and is categorized as field research. Data were collected through observation, interviews, and document studies using a descriptive technique. The findings reveal that the implementation of the Think Pair Share model in Arabic language learning is effective in enhancing students’ learning outcomes and engagement. Students became more active and confident through the three main stages of the Think Pair Share model: first, providing a question or problem for students to think about individually (think); second, asking them to discuss in pairs (pair) to share answers and refine their understanding; and third, selecting several pairs to present their discussion results in front of the class (share), followed by correction and feedback. The supporting factors include providing opportunities for students to think independently, encouraging peer discussion, presenting ideas in front of the class, fostering collaboration among students, accelerating comprehension of learning materials, and helping improve Arabic speaking skills. Meanwhile, the inhibiting factors consist of limited vocabulary, difficulties in constructing sentences, students’ shyness or lack of confidence and fear of making mistakes when speaking, the need for more time in discussion and presentation, and limited facilities.

Therefore, this model can be a useful alternative for educators in increasing student engagement and learning outcomes in grade IV.  

Creative thinking skills are fundamental competencies to be nurtured in 21st-century learning, especially within science education. One promising approach to developing these skills is the use of an Etno-STEM integrated E-Module implemented through the Project-Based Learning (PjBL) model. The Etno-STEM integration seeks to link local wisdom and culture with the domains of science, technology, engineering, and mathematics, thereby creating meaningful, contextualized learning experiences. This study aims to investigate the impact of implementing an Etno-STEM integrated E-Module through PjBL on students’ creative thinking skills. The research employed a quasi-experimental design with two classes: an experimental group using the Etno-STEM integrated E-Module and a control group using cooperative learning strategies. Research instruments comprised both test and non-test tools. The test instrument included objective-reasoned questions aligned with four creative thinking indicators—fluency, flexibility, originality, and elaboration—while the non-test instrument involved structured observation sheets to monitor learning implementation. Data analysis demonstrated that the Etno-STEM integrated E-Module using the PjBL model significantly improved students’ creative thinking skills compared to conventional approaches. This finding highlights the potential of combining local wisdom with innovative instructional models as an effective and culturally responsive strategy for advancing science learning aligned with 21st-century educational demands.

This community service activity was implemented using a service learning approach through a business planning and public communication training program for the Merah Putih Village Cooperative in Huta Baringin.

The implementation method was carried out through the stages of needs identification, formulation of training materials, simulation practices, and intensive mentoring. The results of the activity showed an increase in cooperative members' understanding in developing business plans based on local potential and improved public communication skills, both within the organizational context and externally to strategic partners. This program not only strengthens the cooperative's independence but also demonstrates the relevance of the service learning model in connecting the roles of academics, students, and the community collaboratively. Thus, this training contributes to local economic empowerment and strengthening institutional communication capacity at the village level.

This study aims to describe the implementation of discipline values and the obstacles faced at MI Darul Hikmah Agung Jaya. Using a descriptive qualitative approach, data were collected from teachers, students, and parents through interviews, observations, and documentation, then analyzed through data reduction, display, and conclusion drawing. Data validity was ensured by triangulation of techniques and sources. The findings show that teachers instill discipline values through two main techniques. First, external control, in which teachers give warnings, threats, or punishment to undisciplined students and provide rewards or praise to those who obey the rules. For example, students who consistently complete homework may receive additional grades or verbal appreciation. Second, teachers also become role models, demonstrating punctuality, neat appearance, polite language, and respectful attitudes, thereby fostering discipline by example. Furthermore, teachers apply cooperative control, emphasizing collaboration and agreements between teachers and students. This approach promotes tolerance, respect, and responsibility by involving students in creating and maintaining classroom rules. However, some obstacles were identified. Teachers were sometimes less assertive in enforcing discipline, and limited variation in teaching methods led to student boredom. In addition, inadequate attention, motivation, and parental support negatively influenced students’ discipline, resulting in lateness, incomplete assignments, and other undisciplined behaviors.

This research was conducted on fourth-grade students of SD Negeri 01 Dagen Karanganyar with the aim of identifying the improvement of critical thinking skills in IPAS learning by applying the Cooperative Learning Model of the Teams Games Tournament (TGT) type during the 2024/2025 academic year. The study involved 25 students, consisting of 16 male students and 9 female students. This research belongs to quantitative research with a One-Group Pre-Test Post-Test Design. The research procedure began with administering a tryout test to determine the number of valid items to be used. The validity test results showed that 20 items met the validity criteria during the tryout. Data analysis was conducted using the One-Sample Shapiro-Wilk test for normality and the Paired Sample T-Test for hypothesis testing. Based on the analysis, the results showed a significance value of < 0.000 with a significance probability of < 0.05. Therefore, the findings are consistent with the hypothesis, namely: “There is an effect of using the Teams Games Tournament (TGT) Learning Model in IPAS learning on the critical thinking skills of fourth-grade students at SD Negeri 01 Dagen Karanganyar in the 2024/2025 academic year.” This indicates that the TGT model can enhance students’ ability to think critically, helping them develop essential skills in problem-solving, analysis, and decision-making, which are crucial for their academic success and future learning processes.

This research is a Classroom Action Research (CAR) conducted in two cycles. The subjects were 24 students of class XII TM 2 of the Mechanical Engineering Expertise Program at Semen Padang Vocational School in the odd semester of the 2025/2026 academic year. Data collection was carried out through learning activity observation sheets, practical assessment sheets, and multiple-choice tests to measure students' cognitive learning outcomes. The implementation of Creative Products and Entrepreneurship learning at Semen Padang Vocational School was previously teacher-centered. Students tended to be passive listeners during the learning process, which led to low participation, minimal interaction, and a lack of understanding of the material. As a result, most students were unable to achieve the Minimum Completion Standards (SKM). Based on this, the Jigsaw Cooperative learning model is considered suitable for application in Creative Products and Entrepreneurship learning, because it is able to create a student-centered learning atmosphere and encourage active involvement and cooperation between students. The results of the study prove that the application of the Jigsaw Cooperative learning model is effective in improving student learning outcomes. This is based on the average student learning outcomes in cycle 1 of 75.2, where 17 students were declared complete. In cycle II, the average student learning outcomes were 85.2 with 21 students declared complete. The significant improvement in cycle II indicates that the Jigsaw Cooperative Learning model is not only effective in improving cognitive learning outcomes but also able to improve the quality of interactions between students in the learning process. Students become more active in discussions, disseminating information, and are responsible for understanding the material they are learning and sharing with their groups.

This study aims to determine: 1) whether there are differences in social skills before and after the implementation of the Team Games Tournament (TGT) cooperative learning model and the direct learning model in the science subject for fourth-grade students of SDN X; and 2) how much influence the use of the TGT cooperative learning model has on students' social skills. The background of this study is based on the importance of developing social skills from an early age, especially through a collaborative learning approach that encourages active interaction between students. Social skills are considered essential for students to build collaboration, responsibility, and tolerance in classroom settings. The method used in this study is a quantitative approach with a quasi-experimental design. The research sample consisted of fourth-grade students who were divided into two groups, namely the experimental class that implemented the TGT model and the control class that used direct learning. The research instrument was a social skills test sheet with four main indicators, namely cooperation, communication, responsibility, and tolerance. The cooperative learning model provides opportunities for students to learn not only academically but also socially through structured interaction. The results of the study showed a significant difference in the improvement of social skills between the experimental and control groups. Students in the experimental group experienced greater improvement in social skills, particularly in cooperation and communication. The TGT model has been proven to create a fun learning atmosphere, foster healthy competition, and encourage students to be more active in discussions and group activities. This finding confirms that TGT can be an effective strategy to improve students' social competence in elementary schools. Therefore, it can be concluded that the TGT cooperative learning model has a positive influence on improving students' social skills. This study recommends implementing TGT as an alternative effective learning strategy in science subjects in elementary schools.

This study aims to analyze the potential and challenges in implementing Fellowship-Based Cooperative Learning in D.I Edutainment, especially for Generation Z. The method used in this qualitative research is a case study, with data collection conducted through semi-structured interviews, participant observation, and documents. The unit includes the analysis of Gen Z participation, and involves facilitators, namely D.I Edutainment managers as informants. D.I Edutainment shows significant potential in implementing fellowship-based cooperative learning. Thanks to the interactive edutainment concept, small programs, and adequate human resource support. However, this study also identified challenges such as Generation Z's relatively short attention span, preference for digital media, variations in self-confidence levels, and the need for structure and motivation for ongoing collaboration. It is recommended that D.I Edutainment utilize, develop interactive and collaborative vehicles, train facilitators, design interesting project groups, and optimize community courage. From an academic perspective, further research is needed on the impact of cooperative learning, the role of technology, Generation Z's perceptions, and their social skills measurement models.

This study aims to analyze the correlation between learning models and student achievement at SMA Negeri 1 Kuala by applying the Apriori algorithm in data mining, using Rapid Miner software as the primary tool for analysis. The research is motivated by the shift in educational approaches from conventional teacher-centered methods toward more innovative strategies such as project-based learning and cooperative learning, which are expected to foster higher levels of student engagement and improve academic outcomes. In many schools, particularly at the secondary level, the choice of learning model, availability of facilities, and attendance rates are crucial factors that shape learning effectiveness and student performance. The data collected in this study include student grades, the types of learning models implemented, school facility conditions, and attendance rates for the 2023/2024 academic year, covering a total of 680 students. The Apriori algorithm was employed to discover hidden patterns and associations among these variables, enabling the identification of relationships between learning factors and academic achievement. By applying Rapid Miner software, the research systematically generated association rules that reflect meaningful correlations in the dataset. The results indicated that the use of the Indonesian language subject in combination with a cooperative learning model, adequate and complete school facilities, and good student attendance was strongly associated with the attainment of an A grade. This finding was supported by a support level of 53.33% and a confidence level of 100%, suggesting a robust and reliable relationship between these factors. The implementation of data mining techniques through Rapid Miner not only allowed for efficient data processing but also provided practical recommendations for educators and school administrators in designing effective instructional strategies.
