Coram Mundo : Jurnal Teologi dan Pendidikan Agama Kristen 2026 Sekolah Tinggi Teologi Injili Arastamar (SETIA) Ngabang

This study aims to explore how the inquiry approach functions as a pedagogical strategy in Christian Religious Education to enhance students’ spiritual discernment. The background of this research arises from the tendency of learning practices that remain predominantly focused on cognitive aspects, thereby not fully cultivating spiritual sensitivity in life decision-making. This study employs a qualitative method with a descriptive-analytical approach through a review of theological and pedagogical literature, conceptual analysis, and reflection on classroom learning practices. The analysis focuses on the relationship between the core elements of inquiry questioning, investigating, dialoguing, and reflecting on knowledge and the process of developing the ability to discern God’s will in the real-life contexts of students. The findings indicate that inquiry effectively creates a reflective learning experience that integrates cognitive, affective, and behavioral dimensions, enabling students not only to understand faith teachings theoretically but also to consider Christian values in concrete situations. This approach encourages active participation, constructive and critical dialogue, and fosters habits of faith reflection, moral sensitivity, and personal responsibility. Thus, inquiry is proven to be a relevant pedagogical method for achieving the theological goal of Christian Religious Education, namely the formation of spiritual discernment that guides students’ attitudes, decisions, and actions in daily life.

Python programming has become a fundamental competence in the digital era, yet students often struggle to transform algorithmic logic into functional code. This gap between conceptual understanding and practical implementation skills requires a thorough investigation into learning challenges within the Industrial Informatics Engineering Technology (TRIN) program at Politeknik Manufaktur Bandung. Grounded in Bloom's Revised Taxonomy and Cognitive Load Theory, this descriptive quantitative study utilized a Likert-scale questionnaire and an objective comprehension test administered to 87 third-year students. Data were analyzed using descriptive statistics to map performance across three aspects: conceptual understanding, syntactic comprehension, and implementation ability. Results indicate the conceptual aspect achieved the highest average of 4.15, followed by syntax at 3.56 and implementation at 3.54, with objective test accuracy rates of 76.09%, 65.52%, and 67.36%, respectively. Major obstacles identified include difficulties with looping, debugging, and comparison operators. Therefore, enhanced structured practice and Project-Based Learning approaches are recommended to strengthen students' implementation competencies.

Sleep duration and sleep quality are essential physiological needs that play a significant role in the emotional and behavioral development of children aged 3–6 years. Adequate sleep supports brain development, cognitive functioning, emotional regulation, and social interaction skills in early childhood. Conversely, poor sleep duration and low sleep quality may negatively affect children’s attention, mood stability, and ability to interact socially with peers and caregivers. This article is a literature review using a systematic review approach that analyzes 10 scientific articles published between 2016–2026 to evaluate the relationship between sleep duration and sleep quality with emotional and behavioral problems in preschool children. The article selection process followed the PRISMA flow diagram, with articles sourced from Google Scholar, PubMed, and ScienceDirect databases. The findings consistently indicate that inadequate sleep duration and poor sleep quality are associated with increased emotional and behavioral problems, including hyperactivity, anxiety, emotional dysregulation, and difficulties in social interaction among children. Furthermore, sleep disturbances were found to negatively influence children’s emotional self-regulation abilities, which are crucial for adaptive behavior. Therefore, ensuring adequate sleep duration and improving sleep quality are important strategies to support optimal emotional and behavioral development in preschool-aged children.

This study addresses the limited integration of environmental education, Islamic values, and creative learning practices in existing pedagogical models. It proposes an eco-friendly Islamic calligraphy approach as an innovative medium for recycling-based learning that promotes both ecological awareness and spiritual development. The study adopts a Participatory Action Research (PAR) design involving 22 students from diverse educational levels at Sanggar Bimbingan Bintang Sembilan. Data were collected through structured observations, semi-structured interviews, and documentation, and analyzed using an iterative qualitative framework to identify changes in students’ cognitive, affective, and behavioral domains. The findings indicate that students initially exhibited low environmental awareness, minimal engagement, and limited ability to utilize recyclable materials creatively. Following the intervention, there was a substantial increase in active participation, creative output, and conceptual understanding of environmental sustainability. Students also demonstrated observable behavioral shifts, particularly in waste reuse practices and environmental responsibility. In addition, the incorporation of Islamic values reinforced ethical awareness and strengthened students’ sense of stewardship toward the environment. This study contributes to the advancement of interdisciplinary learning by offering a contextual and practice-oriented model that integrates environmental education, religious values, and art-based pedagogy. The proposed approach not only enhances student engagement but also fosters holistic learning outcomes, making it a viable alternative to conventional instructional methods in sustainability education.

This study aims to describe the strategies of Islamic Religious Education (PAI) teachers in increasing the learning participation of low-ability students at SDN 008 Tebing Karimun. Learning participation is an important indicator of learning success, but in reality there is still low student involvement in the learning process. Inhibiting factors come from internal aspects such as low confidence and limited cognitive abilities, as well as external aspects in the form of less varied learning strategies and less supportive classroom environments. This study uses a qualitative approach with a descriptive type, involving PAI teachers as the main informants and students as supporting informants. Data was collected through observation, interviews, and documentation, then analyzed with an interactive model that included data reduction, data presentation, and conclusion drawn, and tested for validity through triangulation. The results of the study showed that teachers' strategies include active learning, group discussions, individual approaches, and the use of learning media. The obstacles faced include low student confidence, cognitive limitations, and lack of variety of methods. The solutions carried out by teachers are in the form of providing motivation, applying innovative methods, and creating a conducive learning environment. This study concludes that PAI teachers' strategies play an important role in increasing the learning participation of low-ability students through innovative, interactive, and student-centered learning.

This literature study examines the process of self-regulation in transforming compliance with school rules originating from external pressure into behavioral regularity emerging from personal awareness, and its impact on the effectiveness of student learning outcomes. Using a qualitative approach with content analysis method, this study synthesizes relevant literature to build a theoretical framework on how self-regulation facilitates the internalization of disciplinary values. The findings reveal that self-regulation occurs through a series of interconnected stages including goal setting, strategy planning, self-monitoring, evaluation, and adjustment. The success of this process is determined by internal motivation, appropriate environmental support, positive direct experiences, and healthy emotional management. Strong self-regulation directly impacts learning outcome effectiveness through improved cognitive strategies, strengthened intrinsic motivation, enhanced time and environment management, and developed capacity to constructively cope with failure. Learning outcomes achieved through self-regulation processes are characterized by lasting understanding, knowledge transfer ability, and the formation of lifelong learning dispositions. Schools and teachers play strategic roles in strengthening self-regulation through curriculum design that supports autonomy, formative feedback, role modeling, and collaboration with parents. This study contributes theoretically by positioning self-regulation as the central mechanism bridging external influences and internal disposition formation.

Arabic language learning is influenced not only by cognitive ability but also by students’ learning characteristics, including affective, social, and physiological dimensions, particularly the phenomenon of language anxiety that often hinders language performance. This study aims to analyze the relationship between students’ learning characteristics and the emergence of language anxiety in Arabic language learning, as well as to formulate its implications for instructional strategies. This research employs a qualitative approach through a conceptual study based on relevant literature concerning learning characteristics and language anxiety. The findings indicate that variations in students’ characteristics contribute to different levels of anxiety across the four language skills: listening, speaking, reading, and writing. Language anxiety is multidimensional and affects students’ participation, motivation, and academic performance. Therefore, Arabic language instruction should be designed using differentiated, communicative, and student-centered approaches while fostering a supportive learning environment. The study highlights the importance of the teacher’s role as a facilitator who understands students’ cognitive and affective dynamics in order to create more effective, humanistic, and responsive Arabic language learning.

The development of digital technology has driven significant changes in modern learning methods by integrating various multimedia media. However, multimedia's ability to facilitate learning depends largely on the extent to which its presentation aligns with the principles of learning psychology, particularly those outlined in the Cognitive Theory of Multimedia Learning (CTML). This study aims to examine the role and effectiveness of multimedia in transforming modern learning methods by combining the results of recent empirical research from 2020 to 2024. This study used the Systematic Literature Review (SLR) method by analyzing 22 journal articles obtained from several databases such as Scopus, Web of Science, ScienceDirect, Google Scholar, and Sinta. Research shows that the use of interactive multimedia helps increase student enthusiasm for learning, participation, understanding of concepts, and the ability to remember course material. However, disorganized multimedia design can add unnecessary mental burden, thereby reducing learning effectiveness. These findings suggest that the successful use of multimedia depends not only on the level of technological advancement but also on the quality of learning design that applies cognitive theory. This study provides a comprehensive summary of the latest research and provides tangible benefits for educators in creating effective digital learning content.

Personal hygiene is an essential factor in maintaining the health and quality of life of the elderly, as aging is often accompanied by a decline in physical strength, mobility, and cognitive function that can reduce the ability to maintain personal cleanliness independently. Limited understanding of the importance of personal hygiene may increase the risk of infections, skin disorders, and other health complications, making education and awareness crucial for promoting better hygiene behavior. This study used a descriptive correlational design with a cross-sectional approach involving 204 elderly individuals residing at the Pucang Gading Elderly Social Service Home in Semarang and Wening Wardoyo Ungaran, with 135 respondents selected using a non-probability sampling technique. Data were collected using validated and reliable questionnaires measuring the level of understanding and personal hygiene practices and were analyzed using the Somers’d statistical test. The results showed that most respondents were female (60%) and aged between 70–79 years (48.9%). The level of understanding of personal hygiene among the elderly was predominantly in the moderate category (72.6%), and their personal hygiene practices were also mostly categorized as moderate (72.6%). Statistical analysis revealed a p-value of 0.000 (<0.05) with a correlation coefficient (r) of 0.472, indicating a positive and significant relationship between the level of understanding and personal hygiene practices. These findings suggest that improving knowledge through continuous education and guidance from health workers is necessary to enhance awareness, independence, and hygiene behavior among the elderly.

Expressive feelings therapy is a form of mental health nursing modality therapy that aims to help individuals express their thoughts and emotions openly without violating the rights of others. This study aims to explore the effectiveness of cognitive therapy focused on “expressing feelings” in improving emotional expression abilities among female patients in the recovery phase at the Anggrek Ward of the Aceh Government Mental Hospital. This descriptive qualitative study was conducted through group therapy activities with structured stages, using media such as emotion expression picture cards and a spin-the-bottle game as interaction stimuli. The population consisted of 18 patient in the Anggrek ward, with a sample of 12 patients who were cooperative, psychologically stable, able to communicate bidirectionally, and willing to participate in group therapy. The results showed that participants experienced an improvement in their ability to express emotions such as happiness, sadness, anger, and anxiety more openly, accompanied by increased social interaction and reduced emotional tension. The therapy also encouraged greater self-confidence and a sense of emotional relief. These findings support that expressive feelings therapy can be incorporated as part of routine nursing interventions for patients who experience difficulties in emotional regulation. It is recommended that further research be conducted over a longer duration and with a broader scope to strengthen the validity of the findings.

Science lessons in primary school significantly contribute to the early development of logical, scientific and systematic reasoning skills.   However, learning science can be challenging, especially when it comes to understanding abstract concepts and cause-and-effect interactions.   This is due to the fact that, as per Piaget's theory, primary school students are still in the concrete operational stage and have limited cognitive growth. Data regarding abstraction ability and causal reasoning in the context of science education were collected from various scientific sources using the literature review research methodology.  According to the research findings, STEAM integration, project-based learning strategies such as Project Based Learning (PBL), and the use of real and visual aids can help lower learning barriers. Successful learning is also influenced by the teacher's role as facilitator, which involves presenting the material in a relevant and contextualized way and fostering a positive learning environment. Real-world examples and exceptional examples, such as the use of worksheets based on cause-and-effect relationships and basic experiments, demonstrate how useful these strategies are for improving abstract thinking and understanding of cause-and-effect relationships. Developing innovative teaching methods based on practical, exploratory and integrative experiments is essential for maximizing the scientific understanding of primary school students.

Senior high school students represent a strategic age group transitioning into adulthood and are expected to become future leaders of the nation. In the context of achieving Indonesia’s Vision 2045, threats to national resilience are no longer dominated by military aggression, but rather by non-military challenges in the form of cognitive warfare. One prominent manifestation of this threat is the massive exposure of students to low-value digital content, commonly referred to as brain rot, on social media platforms. Such content has the potential to reduce attention span, critical thinking ability, and national awareness among adolescents. Consequently, senior high school students have become a vulnerable group in the spread of misinformation, disinformation, and ideologies that contradict Pancasila values. This community service activity aims to provide training and strengthen national defense character (bela negara) among senior high school students in Jakarta through an educational and participatory approach. The methods employed include the delivery of conceptual materials on national defense awareness and digital literacy, as well as national defense debate simulations designed to enhance students’ critical, argumentative, and ethical thinking skills. The results indicate an improvement in participants’ understanding of national defense values and their ability to express logical and responsible arguments. This activity is expected to contribute to the development of a resilient, critical, and nationally-minded young generation capable of facing contemporary challenges in the digital era.
