Abstract

The researcher investigated and explored a solution of non-directed or no hint of mathematics problems presented visually or algebraic, and to embed the empirical verification thinking. The tip is a way to solve, so the students can answer the questions based on their state of mind by observing their trajectories of thinking from the steps of the solution. That is conducted at the Mathematics Education Department of Tanjungpura University at West Borneo of Indonesia for two semesters. The problems are from Researcher Repertoire, test item of Teacher Profession Education of National Indonesia, and Flanders Mathematics Olympiad. Before the issues given to the students, the construct validity has calculated from intake participants using Cramer’ Test with C coefficient is equal to 0.83. We analyze the students’ empirical verification thinking of their solutions. The analysis is about the trend of the thinking, model of representation, and completeness of the logical steps. The results are: the pattern of thinking tends to linear model or of meta-pattern, the description tends to be non-linear or varies of the solution, and the logical steps tend to be a non-recognizable form of thinking. In general, the more visual representations, the less thinking models of the representations; the answers based on algebraic thinking; the visual illustrations are limited, where the algebraic without any manipulation and not need any hint; and the visual images used are part of it in solving the problems and no manipulation.

Abstract

This study aims to enhance students' understanding of mathematical proof through the etymology-based learning method. The research employs a descriptive approach to observe and analyze students' mathematical proof patterns in various contexts. Data were collected from 30 students enrolled in a master's degree program in mathematics education who demonstrated varying abilities in mathematical proof. The findings indicate that using action words or phrases during instruction can support students' ability to differentiate relevant terms and avoid misinterpretation of context. Furthermore, comparative understanding of source and target problems improves students' mathematical proof patterns in broader learning contexts. The implications of this study highlight the importance of integrating language-based and formal approaches in mathematics teaching to enhance students' mathematical proof abilities holistically.

Abstract

Background: Vocational schools in border areas face systemic challenges such as limited infrastructure and poor curriculum-context alignment, hindering effective mathematics instruction and student engagement.Aims: This study investigates how mathematics learning is organized and implemented in a vocational high school situated in the Entikong border area of West Borneo, Indonesia. The research seeks to identify instructional patterns, contextual challenges, and adaptive strategies used by educators under constrained conditions.Method: Using a qualitative case study design, data were gathered through direct classroom observation, semi-structured interviews with teachers and school leaders, and review of official teaching documents. Thematic analysis and data triangulation were employed to ensure rigor and credibility.Results: The analysis highlights a continued reliance on teacher-centered instruction, minimal use of contextual or vocationally integrated methods, and limited student engagement. Assessment practices predominantly measure cognitive outcomes, lacking elements that support student reflection or vocational competencies. Curriculum delivery is often disrupted by time limitations and infrastructural shortfalls.Conclusion: Improving mathematics instruction in border-based vocational schools necessitates flexible teaching models tailored to the local context. Strengthening professional development, embedding authentic assessments, and enhancing school-community collaboration are crucial steps toward addressing educational disparities in underserved regions.

Abstract

This research examines the transformation of educational supervision in improving school quality through the integration of transformative leadership, teacher professionalism, and a global-contextual perspective. The background of the study is based on the paradigm shift in supervision from an administrative approach towards reflective and collaborative coaching. The purpose of this study is to explore the dynamics of implementing supervision that emphasizes coaching, professional dialogue, and the adoption of international practices within a local context. The research approach used is descriptive qualitative with data collection techniques through interviews, observation, and documentation studies, which are then validated through a member check and triangulation process. The results of the research indicate that school principals play a crucial role as collaborative leaders in shaping a participatory and reflective supervision ecosystem. Teachers experienced an increase in pedagogical and vocational capacity through PLC (Professional Learning Community) forums and practice-based coaching. Supervision is also beginning to be used as part of the internal quality assurance system. Structural obstacles such as time constraints and resistance are still encountered but can be overcome through innovative supervision strategies. In conclusion, an adaptive and contextual transformation of supervision is capable of driving continuous improvement in the quality of education.

Abstract

The transformation of education in the digital era has created new challenges and opportunities in governance, leadership ethics, and technological integration. This study aims to examine educational management from a global research perspective by highlighting the dynamics of digitalization, ethical principles, and governance policies. A qualitative multidisciplinary approach was employed using a systematic literature review (SLR). Data were sourced from 40 high-reputation scientific publications, including Scopus, Web of Science (WoS), SINTA, and DOAJ indexed journals. The data were analyzed through thematic analysis and narrative synthesis. The findings reveal five main points: (1) global trends indicate a shift towards reflective and collaborative leadership; (2) digitalization is driving the adoption of AI-based learning systems and big data; (3) ethical principles are a key determinant of the credibility of educational governance; (4) educational policies require cross-cultural contextual adaptation; and (5) a gap persists between the integration of theory and practice. In conclusion, modern educational management needs to be developed through a multidisciplinary approach that combines digital innovation, ethical values, and sensitivity to the global context.
