Abstract

This study aims to determine the effectiveness of implementing video-based Information Technology learning on the learning outcomes of first-semester students in the Mathematics Study Program at Universitas Muhammadiyah Kotabumi. The research method used is a pre-experimental design with a one-group pretest-posttest model. The research sample consisted of 28 students. Data were obtained through pretest and posttest assessments, as well as a student perception questionnaire. The analysis results showed that the average pretest score was 56.82 with a standard deviation of 6.47, while the posttest average increased to 78.18 with a standard deviation of 6.79. The Shapiro-Wilk normality test indicated that the data were normally distributed, with significance values of 0.645 for the pretest and 0.151 for the posttest. The paired sample t-test produced a significance value of 0.000 (<0.05), indicating a significant difference between pretest and posttest scores. In addition, the analysis of student perception questionnaires showed an average score of 4.38, categorized as “strongly agree.” Thus, video-based Information Technology learning is effective in improving learning outcomes and receives a positive response from students.

Abstract

The quality of education in Indonesia continues to face numerous challenges, particularly at the school level, where disparities in resources and management affect learning outcomes. In this context, the visionary leadership of school principals emerges as a critical factor in driving sustainable improvements and transformative change. This study aims to explore how visionary leadership enhances educational quality and to identify the key characteristics and strategies principals use to effectively lead change. Utilizing a descriptive qualitative approach, data were collected through in-depth interviews and participatory observations conducted at SMKS 17 Sukoharjo. The findings reveal that visionary principals transcend traditional administrative roles, positioning themselves as inspirational instructional leaders who actively foster collaboration among staff, promote pedagogical innovation, and enhance teacher professionalism. They also cultivate inclusive and meaningful learning environments that empower students as active participants in their education. Such leadership effectively bridges national education goals with the unique needs of the school community, fostering a shared awareness of quality education as a moral and social responsibility. Visionary principals demonstrate the ability to anticipate future challenges, adapt to evolving circumstances, and guide their schools toward long-term success. Therefore, strengthening visionary leadership through targeted development programs is essential, preparing principals to lead with clarity, purpose, and a continuous commitment to improvement in an ever-changing educational landscape.

Abstract

Conceptual difficulties and visual representation barriers are often major challenges in learning integers, especially related to understanding negative numbers and mathematical operations such as addition and subtraction. This study aims to identify the problems faced by students in learning integers, evaluate the effectiveness of various teaching methods, and propose innovative approaches to improve students' understanding. The methodology used is a systematic review based on Systematic Literature Review (SLR), by analyzing relevant research articles using PRISMA guidelines. This study examines various learning strategies, such as the use of realistic contexts, innovative visual models, manipulatives, and interactive technology. The results showed that a real-world context- based approach and the use of visual models can significantly improve students' understanding compared to conventional methods. Students who engaged in manipulative-based learning and class discussions also showed better mathematical thinking flexibility. These findings highlight the need for further exploration of the use of real contexts, more innovative visual models, and the application of gamification technology in integer learning. In conclusion, integer learning requires a more innovative approach by integrating realistic contexts, new visual models, and interactive technology. This not only increases student engagement but also supports the development of conceptual and procedural abilities more effectively.
