Educational supervision serves as a key instrument in improving educational quality; however, its implementation in elementary schools often faces systemic challenges that affect teacher performance and learning quality. This study aims to analyze the implementation of educational supervision by school principals to improve the performance of Catholic Religious Education (CRE) teachers in enhancing educational quality at Inpres Natarita Elementary School. The research employs a descriptive qualitative approach with the school principal and CRE teacher as research subjects. Data collection was conducted through in-depth interviews, participatory observation, and documentation. Data analysis used the interactive model of Miles and Huberman with stages of data reduction, data presentation, and conclusion drawing.The findings reveal significant disparities between the implementation of administrative supervision and academic supervision. Administrative supervision is consistently implemented but remains procedural-mechanistic in nature, while academic supervision experiences systematic deficits with minimal frequency (once per semester). This condition impacts the competence-performance gap phenomenon in CRE teacher performance, characterized by the dominance of lecture methods, limited learning innovation, and minimal professional initiative. Educational quality shows acceptable achievement in graduation rates but has not been optimal in potential realization and educational value-added.Educational supervision at SDI Natarita has not achieved optimal effectiveness due to a paradigm that remains compliance-oriented rather than development-oriented. A fundamental reorientation toward holistic and transformative supervision is needed to optimize teacher performance and educational quality.

 The instructional leadership of school principals is a strategic factor in improving the quality of education, particularly in shaping teacher performance and professionalism. In the context of modern educational challenges, school principals do not only act as administrative managers but also as educational leaders capable of guiding, mentoring, and developing teachers' capacities. This study aims to identify the influence of instructional leadership on teachers' performance and professionalism, as well as to uncover the dominant leadership strategies used in schools. The research questions addressed are: (1) How does instructional leadership influence teacher performance and professionalism? and (2) What are the dominant instructional leadership strategies in improving education quality? The study method uses a systematic literature review (SLR) approach by searching articles through Google Scholar and Publish or Perish (PoP) using the keyword ‘guided inquiry search.’ Out of a total of 50 articles, five main articles were analysed in depth. The findings indicate that instructional leadership significantly influences teachers' work motivation, self-efficacy, and professional development. The most dominant strategies include academic supervision, strengthening the school's vision, and fostering a collaborative work environment. This study underscores the urgency of strengthening the instructional role of school principals and recommends further studies based on meta-analysis and a cross-national contextual approach.

This study aimed to develop a competency-based performance evaluation model for mathematics teachers at the junior secondary level. Recognizing the crucial role of teacher quality in student achievement, the study focused on measurable aspects of performance, including content mastery, instructional management, and professional commitment.

This study aims to describe the dynamics of school leadership at a primary school affected by limited leadership experience and health-related constraints. Using a descriptive qualitative approach and in-depth interviews with several teachers, the findings reveal that the principal adopts a situational leadership style characterized by flexible and delegative practices. The principal places significant trust in senior teachers to carry out daily operational functions and decision-making processes. While this strategy fosters teacher autonomy and ensures the continuity of school activities, it also reveals weaknesses in supervision, quality control, and the symbolic presence of leadership. The lack of direct supervision results in unclear performance evaluations and weak program coordination. The study concludes that the effectiveness of situational leadership relies heavily on the strength of interpersonal relationships among staff and the existence of supportive internal systems. It is recommended that the principal strengthen the management team and establish a more structured communication system to sustain leadership quality and educational standards.

The world of education has undergone a major shift as a result of advances in information and communication technology. This study compares conventional and digital learning methods for distance learning (PJJ) across the board, with the aim of finding out what is effective, what is not effective, and how the two methods affect student learning outcomes and experiences. Conventional learning, which relies on direct interaction between teachers and students, emphasizes elements such as giving feedback, easy to do, structured, and routine. It has the advantage of being able to facilitate direct interpersonal communication, provide intensive supervision and guidance, and create a competitive learning environment. However, this method has some limitations, especially in terms of time and space flexibility. It is also not able to meet the learning needs of individuals in large groups. On the other hand, digital learning offers greater flexibility, access to a wide range of educational resources, and increased interactivity through the use of online collaboration tools, e-learning platforms, and video conferencing. The use of technology allows learning content to be presented in a systematic, structured and engaging manner, increasing student motivation and participation. In addition, it allows materials to be tailored to each student's learning style and conditions, and supports collaborative and independent learning. Challenges include the possibility of misuse of technology, limited access in some areas, lack of direct social interaction, and reliance on digital infrastructure and capabilities. The research results indicate that digital learning generally enhances student learning outcomes more significantly compared to conventional learning, especially in terms of distance learning (PJJ). Digital strategies such as structured instructional design, integration of practical experiences, motivational support, and time management have been shown to improve student interaction, understanding, and independence. However, digital and conventional learning methods can complement each other to achieve optimal effectiveness. The application of these strategies not only boosts students' academic performance but also equips them with the essential skills to tackle future challenges. 

Principal management plays a crucial role in the development of teachers, significantly influencing their professional competence and performance in carrying out educational responsibilities. This study aims to describe and analyze (1) principal management strategies in teacher development, (2) obstacles encountered during the implementation of these strategies, and (3) solutions to overcome the identified obstacles. The research was conducted at SMA Muhammadiyah 8 Palembang using a qualitative descriptive method. Data collection techniques included interviews with school leaders and teachers, direct observations of school activities, and document analysis related to teacher development programs. Data were analyzed using an interactive model consisting of data collection, data reduction, data presentation, and conclusion drawing. The findings show that principal management in teacher development involves structured planning, implementation of professional training, performance evaluation, mentoring programs, and the establishment of collaborative work teams aligned with the school's vision and mission. However, several obstacles were identified in the implementation process, such as limited human and financial resources, differences in teacher readiness and motivation, resistance to new policies or changes, and difficulties in maintaining consistent monitoring and supervision. To address these challenges, school leaders have adopted various strategies, including intensifying teacher training and mentoring, promoting teamwork among staff, utilizing digital technology to support learning and supervision, and building partnerships with external education stakeholders. Additionally, regular evaluations and feedback mechanisms are conducted to ensure that teacher development programs remain responsive to current needs. This research emphasizes the importance of effective leadership and adaptive strategies in fostering continuous professional growth for teachers within the school environment.

This study aims to analyze the contribution of academic supervision by the headmaster and professional teacher discipline to the professional performance of teachers at Madrasah Ibtidaiyah (MI) in Banjarmasin City. Optimal teacher performance is greatly influenced by both internal and external factors, one of which is academic supervision and work discipline. This research uses a quantitative method with a survey approach and descriptive analysis. Data were collected through questionnaires distributed to 100 teachers from various Madrasah Ibtidaiyah in Banjarmasin City, using random sampling techniques. The results show that academic supervision by the headmaster has a significant positive effect on improving teacher performance, where intensive and directed supervision can increase teachers' motivation and teaching competencies. In addition, professional teacher discipline also proves to have a significant contribution to improving teacher performance, where a high level of discipline correlates with an improvement in the quality of classroom learning. Overall, this study concludes that both academic supervision by the headmaster and professional teacher discipline simultaneously have a positive impact on the professional performance of teachers, which in turn contributes to the improvement of education quality in Madrasah Ibtidaiyah in Banjarmasin City. Therefore, improving the quality of supervision and teacher discipline should be a primary focus for the education management at Madrasah Ibtidaiyah.

The orientation of educational institutions is busy with exam scores, and academic grades are the main prerequisites for graduation. As a result, the product produced by students is how high the report card score is and discredits the values of character, life and morality. This causes students to lose focus on character education. For this reason, teachers as the main milestone in learning in the classroom are required to create a learning atmosphere with character based on DOOR (Diversity, Optimism, Option for The Poor, Respect). This is because the character based on DOOR is a guideline in the ministry at the Bethlehem Bandar Baru Foundation. The objectives of the study are: (1) To describe the management model of character education training based on DOOR; (2) Determine the feasibility of the character education training management model based on DOOR; and (3) Determine the effectiveness of the implementation of character education training management based on DOOR at the Bethlehem Bandar Baru Foundation. The research uses a research and development approach to develop a model to improve teacher performance at the Betlehem Bandar Baru Foundation. The research sample is 59 teachers at the Bethlehem Bandar Baru Foundation. The results of the study show: (1) The training model developed is feasible to be used in an effort to improve the performance of teachers of the Bethlehem Bandar Baru Foundation, through the following stages: planning, organizing, moving, and supervising; (2) The training model is effectively used to improve the performance of teachers of the Betlehem Bandar Baru Foundation. There was an increase in teacher performance in the following aspects: learning planning by 42.05%; the implementation of learning is 29.74%; and assessed learning outcomes by 59.49%; and (3) a character training model developed practically for improving teacher performance at the Bethlehem Bandar Baru Foundation, obtained N-Gain Score g = 0.76 > 0.7 (small group trial) and g = 0.79 > 0.7 (limited wide trial); The resulting products were 76.40% (small group trials) and 79.08% (limited wide trials) with the effective category. Based on the results of the study, it is suggested that the improvement of teacher performance at the Bethlehem Bandar Baru Foundation must be carried out with integrated planning, organization, implementation and supervision between the Archdiocesan Foundation, the Foundation's internal supervisors, principals, and teachers.
