Grammatical Cohesion of Writing Section in English Text Books “English for Nusantara” in Kurikulum Merdeka

Yenny Teriana — 2025-11-18

This study examined the grammatical cohesions in writing sections of the English textbooks English for Nusantara, which are intended for seventh and eighth-grade students in Indonesia under the Kurikulum Merdeka. For seventh and eighth grade levels, the study finds and contrasts cohesive devices like conjunctions, ellipses, references, and substitutions using Halliday and Hasan's cohesion framework. A structured observation checklist was used to analyze textbook material using a descriptive qualitative technique. The results show that the seventh-grade textbook uses a wider range of cohesive devices, with references accounting for the majority (66.2%), followed by conjunctions (27.2%). On the other hand, the eighth-grade textbook has no examples of replacement, ellipsis, or lexical coherence and instead mostly uses references (53%) and conjunctions (47%). The eighth-grade text's lack of ellipsis and a narrow variety of coherent devices point to a decrease in linguistic complexity. These findings point to possible discrepancies in grade-level advancement of cohesion tactics and emphasize the necessity of curriculum modifications to improve writing coherence in English language instruction.

The Role of Educational Supervision in Enhancing School Quality: A Theoretical Perspective

Yuni Indrawati — 2025-11-18

Educational supervision has long been recognized as a crucial mechanism for improving school quality, yet its conceptual foundations and operational implications remain varied across educational systems. This article provides a theoretical exploration of how educational supervision contributes to the enhancement of school quality, focusing on supervisory functions, professional development, instructional improvement, and organizational effectiveness. Drawing from classical and contemporary literature, the paper synthesizes multiple perspectives to clarify the conceptual boundaries of supervision and its relationship to teaching-learning outcomes. The review highlights that effective supervision not only evaluates teacher performance but also promotes continuous professional learning, collaborative school culture, and data-driven decision-making. Moreover, the findings emphasize that the role of supervision has shifted from inspection-oriented practices to more developmental and supportive approaches aligned with modern educational quality standards. This theoretical analysis further identifies persistent gaps in the literature, including inconsistent definitions, limited models for contextualized implementation, and insufficient attention to supervisor competencies. The paper concludes by proposing an integrative framework that positions educational supervision as a multidimensional catalyst for school improvement. The framework underscores the importance of leadership capacity, supportive communication, and reflective practice. Overall, the study contributes a holistic understanding of supervision’s strategic role in elevating school quality and provides insights for policymakers, school leaders, and researchers seeking to strengthen supervisory practices.

The Effect of Metacognitive Learning on Improving Students' Critical Thinking Abilities in Learning Needs Identification Learning

Citra Dwi Palenti — 2025-11-18

This study aims to analyze the effect of implementing metacognitive learning on improving students' critical thinking skills in the Identification of Learning Needs course in the Non-Formal Education Study Program, University of Bengkulu. The study used a quasi-experimental method with two groups, namely the experimental group that received metacognitive learning treatment and the control group that used conventional learning. The research subjects consisted of 60 fifth-semester students, with 30 students in each group. Data were collected through a critical thinking ability test that covered aspects of interpretation, analysis, evaluation, inference, explanation, and self-regulation. The results showed that metacognitive learning had a significant effect on improving students' critical thinking skills. The average critical thinking ability score of the experimental group (81.7) was higher than that of the control group (64.5) by 17.2 points. The self-regulation aspect experienced the highest increase, indicating that awareness and control of the thinking process are key to successful learning. Thus, the integration of metacognitive strategies is important to implement in learning design in higher education to foster independence, reflection, and higher-order thinking skills that support lifelong learning.

Integrating Literary Theory into Literature Instruction: A Case Study in the “Literature for Educational Purposes” in English Education Students, University of Bengkulu

Indah Damayanti — 2025-11-18

There has been a continuous debate among university lecturers in Indonesia regarding the proper literary theory integrated into literature subjects for undergraduate English education majors. The lecturers argue that literary theory, distinguished by its theoretical density and highly specialized jargon, is immensely daunting for undergraduate students and thus more applicable to be taught at the graduate level of literary studies. As a result, the conventional literary classroom system should be shifted into the classroom with an ability to understand, to overcome the problems, and to implement the knowledge into the skills that are useful for contributing to students' success in the current condition. Therefore, implementing PBL in integrating literary theory into teaching English literature is essential to address the limitations outlined earlier. A qualitative research approach was employed in this study, utilizing a case study design to investigate a complex phenomenon or event within its natural context. After conducting a case study with the application integrating theoretical frameworks into literary analysis in Literature for Educational Purposes, a more comprehensible understanding of the significant academic value that literary theories contribute to the undergraduate literature classroom was gained. Students are trained to evaluate, analyze, and give value to the text they have read. The application of literary theories into literature classroom instruction has been proven be able to allow students to develop their literary comprehension.
