Abstract

This study aims to investigate the effectiveness of implementing differentiated instruction in improving student learning outcomes in Informatics for Grade X students at a vocational high school. Employing a classroom action research design over two cycles, data were collected through learning outcome tests, student attitude observations, and documentation. Both qualitative and quantitative approaches were utilized in data analysis. The findings reveal that the implementation of differentiated instruction was moderately effective, with an average N-Gain score of 75.6%. There was a significant improvement in student learning outcomes following the application of differentiated instructional methods. Quantitative analysis supported the effectiveness of this approach, as evidenced by a t-test value of 6.256 with 66 degrees of freedom and a significance level of < 0.001, thereby rejecting the null hypothesis (H₀). These results indicate that differentiated instruction can significantly enhance student engagement and academic performance, particularly in subjects such as Informatics that require logical and rapid thinking skills. The study underscores the crucial role of instructional innovation and teacher management strategies in addressing diverse student needs and optimizing learning outcomes. It recommends the broader application of differentiated instruction to enhance teaching quality and student achievement in vocational education contexts

Abstract

This study aims to analyze the strategic role of the principal as an educational supervisor in improving the sustainable quality of teaching and learning at Tabgha Mulia School, Batam. The main focus is on implementing academic supervision through a collaborative and reflective leadership style. The study method used is a descriptive qualitative approach. Data were collected through in-depth interviews, direct observations, and document analysis. The data analysis technique used is the Miles and Huberman model, which consists of data reduction, data display, and conclusion drawing. The results show that the principal’s leadership, which emphasizes collaboration, reflection, and mentoring, positively contributes to improving teacher professionalism, particularly in lesson planning, reflective thinking, and participation in quality development programs. However, several challenges were identified, including the lack of preparedness of instructional materials and unexamined teaching routines. It is concluded that effective academic supervision requires a substantive and contextual approach, along with the principal’s role as a facilitator in fostering an eval_uative culture within the school environment. The implication of this research highlights the importance of strengthening the principal’s capacity in conducting pedagogical supervision to achieve adaptive and sustainable teaching and learning quality
