Transformasi Mutu Pendidikan melalui Kepemimpinan Sekolah yang Visioner
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.

Pengembangan E-LKPD Berbasis Liveworksheet Menggunakan Pendekatan Berbasis Masalah Dalam Meningkatkan Kemampuan Numerasi Kelas X SMA
Keterampilan numerasi sangat penting dalam pendidikan saat ini. Penelitian pengembangan ini bertujuan untuk membuat lembar kerja siswa elektronik interaktif (E-LKPD) berbasis Liveworksheet, menggunakan pendekatan pembelajaran berbasis masalah untuk meningkatkan keterampilan numerasi pada siswa statistika kelas 10. Penelitian ini mengacu pada kriteria validitas, praktikalitas, dan efektivitas. Metode Penelitian dan Pengembangan (R&D) digunakan, mengikuti model ADDIE, yang meliputi tahap Analisis, Desain, Pengembangan, Implementasi, dan Evaluasi. Instrumen penelitian terdiri dari lembar validasi ahli, uji kelayakan guru, pre-test dan post-test dengan masing-masing dua pertanyaan, dan angket respon siswa. Penelitian ini melibatkan 36 siswa dari kelas X E.10 di SMAN 2 Kota Jambi. Hasil penelitian menunjukkan bahwa E-LKPD yang dikembangkan sangat layak, dengan skor 97% untuk validitas, 96% untuk praktikalitas, dan 95% untuk efektivitas. Selain itu, keterampilan numerasi siswa meningkat secara signifikan, dengan skor n-gain 0,8, dikategorikan tinggi. Temuan ini menunjukkan bahwa E-LKPD berbasis Liveworksheet dengan pendekatan pembelajaran berbasis masalah dalam bidang statistika valid, praktis, dan efektif untuk meningkatkan kemampuan numerasi siswa SMA kelas 10. Oleh karena itu, E-LKPD yang telah dikembangkan dapat dengan yakin digunakan sebagai bahan ajar untuk mendukung pengembangan keterampilan numerasi dalam konteks ini.
Pengembangan Media Pembelajaran Virtual Reality (VR) Berbantuan Millealab Terhadap Pemahaman Konsep Matematis Siswa
The problem in this study is the low conceptual understanding of class VII A students of MTs Negeri 1 Lampung Utara. The purpose of this study was to obtain virtual reality learning media assisted by MilleaLab for understanding mathematical concepts of line and angle material, to determine the feasibility of virtual reality learning media assisted by MilleaLab for understanding mathematical concepts of line and angle material, and to determine the effectiveness of virtual reality learning media assisted by MilleaLab for understanding mathematical concepts of line and angle material. The method used in this study is Research and Development (R&D) with the ADDIE model. The research procedure begins with interviews with students to identify student needs, continues with the development of appropriate VR media, and ends with field trials using measuring instruments to measure the effectiveness of the media. The results showed that the use of VR learning media effectively helped MilleaLab in improving students' understanding of mathematical concepts, with an N-Gain score of 0.79 which is included in the "high" criteria and an effectiveness level reaching 79%. The impulse of this research is that VR learning media can be an effective tool to improve the teaching and learning process, as well as provide a more interesting and meaningful learning experience for students
Pengaruh Model Pembelajaran Discovery Learning Berbantuan Desmos terhadap Pemahaman Konsep Materi Persamaan Garis Lurus
The low the skill level eight grade students at MTs Negeri 1 North Lampung to understand the concept of linear equations result from the implementation of learning models. The learning model that is tought to influence the understanding of the concept of linear equations is the Desmos-assisted Discovery Learning learning model. Its purpose is in the present research was to identify if the Desmos-assisted Discovery Learning model impacts student’s understanding of the concept of linear equations among eighth-grade students at MTs Negeri 1 Lampung Utara. This study applied a Quasi-Experimental Design featuring a Nonequivalent Control Group Design. The population involved in this research consisted of all eighth-grade students at MTs Negeri 1North Lampung. The sampling technique applied was simple random sampling was conducted with clasThe low the skill level eight grade students at MTs Negeri 1 North Lampung to understand the concept of linear equations result from the implementation of learning models.

Korelasi antara Efikasi Diri dengan Kemampuan Berpikir Kreatif Matematis Siswa pada Materi Statistika
This study aims to determine the correlation between self-efficacy and students mathematical creative thinking abilities in statistics material for class Vlll MTsN 3 North Lampung in the 2024/2025 academic year. The research method used is a quantitative method with a correlational design. The study population included all class Vlll MTsN 3 North Lampung students in the 2024/2025 academic year with a total of 223 students. The sample selected from the entire population of MTsN 3 North Lampung amounted to 70 students obtained from the quota sample technique. The data collection technique in this study used a questionnaire instrument with a likert scale model for self-efficacy and a descriptive test instrument for creative thinking abilities. Before testing the hypothesis, a normality test was first carried out using the liliefors test and a linearity tests. The results of this study indicate that there is a correlation between self-efficacy and mathematical creative thinking abilities with a correlation coefficient . This indicates a relationship between self-efficacy and students mathematical creative thinking skills in statistics for grade Vlll students at MTsN 3 North Lampung in the 2024/2025 academic year.
