This study investigates the distribution and characteristics of the Adversity Quotient (AQ) among junior high school students in Kisaran Timur, Indonesia, within the framework of the Merdeka Curriculum, which emphasizes character education. AQ, based on Stoltz’s CORE model—Control, Ownership, Reach, and Endurance—reflects students' capacity to respond to academic and personal challenges. Regional data on AQ in semi-urban settings remain limited, hindering context-specific educational interventions. A quantitative descriptive approach was employed, involving 1,046 Grade VII students from four public junior high schools. Data were collected using a culturally adapted and validated version of the Adversity Response Profile questionnaire. AQ profiles were analyzed using descriptive statistics based on both categorical classification (Climber, Camper, Quitter) and CORE indicators. Findings revealed varying AQ profiles across schools. SMPN 7 had the highest percentage of Climbers (60%), while SMPN 3 had the highest percentage of Quitters (25%). Across all schools, Control and Endurance scores were relatively high, while Ownership and Reach were consistently lower, indicating weaker skills in accountability and limiting the impact of adversity. School-level factors—such as teaching style, peer support, and access to guidance—emerged as influential. The data highlight that student resilience is shaped not only by individual traits but also by the school environment. These findings support the integration of AQ data into targeted character education strategies. AQ-informed interventions such as mentoring, teacher training, and reflective practices can enhance students' resilience and support the goals of the Merdeka Curriculum.

This research aimed to analyze undergraduate students’ mathematical creative thinking abilities (MCTA). This study employs a qualitative descriptive method, with the research subjects being Mathematics Education Study Program students. Tests and interviews were the instruments used for mathematical creative thinking ability. The results of the research show that students' mathematical creative thinking abilities vary, as many as 20% are in the low category (CCTA < 33%), 60% are in the medium category (CCTA between 33% and 67%) and 20% are in the high category (CCTA > 67 %). Understanding mathematical concepts, learning experiences, and motivation all have an impact on students creative mathematical thinking skills. It is hoped that the results of this research can be considered when designing learning that can develop students' mathematical creative thinking abilities.

The rapid development of information technology currently demands a transformation in the education assessment system, especially in Vocational High Schools (SMK). One of the challenges faced is the limited facilities and infrastructure such as computer laboratories that are not comparable to the number of students, so that the implementation of computer-based test (CBT) is less than optimal. The aim is to develop an Android-based CBT assessment system that is integrated with the Case Method in the Business Economics subject in SMK. This innovation is designed so that students can take exams anytime and anywhere, without being constrained by limited computer devices or internship schedules. The ADDIE (Analysis, Design, Development, Implementation, and Evaluation) development method with the Waterfall Development Model approach to build the system. The developed system was validated by material and media experts, followed by small-scale and large-scale trials on class XI students of SMK Negeri 14 Medan. This Android-based CBT system is effective and feasible to use. In terms of usability, this system received a positive response from students, with high scores on indicators of ease of use, speed of access, and time efficiency. The integration of Case Method- based questions has also been shown to improve students' understanding in solving real problems in the field of Business Economics. The CBT system based on Android integrated with Case Method is able to be an effective solution to overcome the limitations of facilities and infrastructure in vocational schools. The implications provide significant contributions in supporting the digitalization of education and improving the quality of learning evaluation in schools.

This study aims to analyze the effectiveness of the Problem Based Learning (PBL) model in improving students’ mathematics learning outcomes on the topic of Systems of Two-Variable Linear Equations (SPLDV). The research subjects were 20 twelfth-grade students of SMA Negeri 1 Percut Sei Tuan, using a quantitative descriptive approach and a one-group pretest–posttest design. The research instrument consisted of an achievement test based on cognitive indicators C4 (analysis), C5 (synthesis), and C6 (evaluation). The results show a clear improvement in students’ learning outcomes after the implementation of PBL. The average pretest score of 16.55 increased to 25.1 on the posttest, while the N-Gain score of 0.63 falls into the medium category. The distribution of learning outcome categories also shifted positively: in the pretest, 7 students were in the low category, 10 in the medium category, and 3 in the high category; whereas in the posttest, no students remained in the low category, 5 were in the medium category, and 15 were in the high category. These findings indicate that the implementation of PBL can enhance students’ analytical skills, problem-solving abilities, and conceptual understanding of SPLDV more deeply, making it an effective instructional model for improving the quality of mathematics learning processes and outcomes.

Penelitian ini bertujuan untuk menganalisis efektivitas penerapan pembelajaran berbasis Higher Order Thinking Skills (HOTS) terhadap hasil belajar siswa pada materi pecahan di kelas VII SMP Methodist 9 Medan. Metode penelitian yang digunakan adalah pra-eksperimen dengan desain One Group Pretest–Posttest. Sebanyak 21 siswa diberikan instrumen tes berbasis HOTS pada tahap pretest dan posttest. Hasil penelitian menunjukkan adanya peningkatan hasil belajar yang sangat signifikan, ditandai dengan kenaikan rata-rata skor dari 15,48 pada pretest menjadi 72,14 pada posttest. Analisis kesalahan juga mengungkapkan penurunan drastis pada kesalahan konseptual (dari 17 menjadi 4 siswa) dan kesalahan prosedural (dari 15 menjadi 3 siswa), sedangkan kesalahan perhitungan masih muncul pada beberapa siswa dan memerlukan perhatian lanjutan. Temuan ini menunjukkan bahwa pembelajaran berbasis HOTS mampu memperkuat pemahaman konseptual siswa, meningkatkan kemampuan analitis, serta memperbaiki proses berpikir logis dalam pemecahan masalah matematika. Secara keseluruhan, pembelajaran berbasis HOTS terbukti efektif dan direkomendasikan untuk diterapkan sebagai strategi pembelajaran yang dapat meningkatkan kualitas pendidikan matematika, khususnya pada konsep pecahan yang membutuhkan pemahaman mendalam.
