Abstract

This study aims to analyze the mathematical problem-solving abilities of 25 eleventh-gradestudents at SMA Negeri 1 Barumun Tengah in solving Higher Order Thinking Skills (HOTS)questions related to arithmetic and geometric sequences. The research employed a descriptivequalitative approach with data collected through written tests, interviews, and observations. Thefindings indicate that most students struggled to solve HOTS questions systematically. Based onPolya’s problem-solving steps, 80% of students were able to understand the problem, 60% coulddevise a strategy, 52% were able to carry out the strategy, and only 36% evaluated their resultsindependently. The greatest difficulties were found in the planning and evaluation stages, primarilydue to low critical thinking skills, lack of exposure to contextual questions, and the dominance ofprocedural-based teaching. These findings highlight the importance of systematically integratingHOTS questions into mathematics instruction to foster students’ higher-order thinking skills.

Abstract

This study aims to evaluate the effectiveness of integrating GeoGebra in mathematicsinstruction through a Problem-Based Learning (PBL) model supported by the TechnologicalPedagogical Content Knowledge (TPACK) framework in teaching three-dimensional geometry. Theresearch subjects consisted of 30 twelfth-grade science students and three mathematics teachersfrom SMA Negeri 1 Sihapas Barumun, while the object of the study was the implementation processof GeoGebra-assisted learning. A mixed-methods approach with an explanatory sequential designwas employed, combining quantitative data (tests and attitude questionnaires) and qualitative data(observations and structured interviews). The results revealed a significant improvement in students'conceptual understanding, with average test scores increasing from 78.5 to 87.2. Additionally, therewas a positive shift in students' affective responses, including enhanced motivation and selfconfidence, as well as increased technical and collaborative skills. In conclusion, the integration ofGeoGebra within the PBL-TPACK framework effectively enhances spatial reasoning, learningengagement, and 21st-century skills in mathematics education.

Abstract

The development of digital technology has significantly transformed the field of education, particularly at thesenior high school level. On one hand, technology offers great potential to enhance student learning motivationthrough broad access to information, interactive media, and flexible learning schedules. On the other hand,digital disruption also presents challenges such as social media distractions, visual fatigue, and unequalaccess to technology. This study aims to identify the factors that influence students’ learning motivation in thedigital era and formulate strategies to optimize the use of technology in education. Employing a descriptivequantitative approach, a survey was conducted involving 72 science-track students at SMA Negeri 1 PadangBolak. The ARCS model (Attention, Relevance, Confidence, Satisfaction) served as the analytical frameworkto assess student motivation. The results show that 70.8% of students reported increased motivation with theaid of digital technology, especially in the areas of attention and satisfaction. However, 55.5% admitted beingdistracted by social media, while 48.6% experienced fatigue due to prolonged screen exposure. The studyrecommends the integration of technology-based pedagogy, the strengthening of digital literacy, andproportional supervision of digital device use to foster effective, meaningful, and motivating learningexperiences

Abstract

In this era of the 4.0 revolution, society is expected to be able to think creatively, namely generating new ideas to solve various problems in daily life and preparing for the future. Enhancing creative thinking ability is considered one of the main learning objectives that is important to be improved in mathematics education. To think creatively in mathematics, students need to understand and actively engage in calculation processes as well as solve problems related to numbers and symbols, which is associated with numerical ability. The objectives of this study are: 1) To describe students' creative thinking abilities in solving mathematical problems based on high numerical ability 2) To describe students' creative thinking abilities in solving mathematical problems based on moderate numerical ability 3) To describe students' creative thinking abilities in solving mathematical problems based on low numerical ability. This research is a qualitative descriptive study. The data collection techniques include tests, interviews, and documentation. The research subjects were students of class VII B at SMP Negeri 1 Tamanan, with six students selected as subjects: two with high, two with moderate, and two with low numerical ability. The results of the study showed that students with high numerical ability met the indicators of fluency and flexibility, students with moderate numerical ability met the fluency indicator, and students with low numerical ability did not meet the indicators of creative thinking ability.

Abstract

Penelitian ini bertujuan untuk meningkatkan hasil belajar matematika siswa melalui model problem-based learning (PBL) pada materi persamaan dan pertidaksamaan linear satu variabel. Metode penelitian yang digunakan adalah penelitian tindakan kelas (PTK) yang diberikan kepada 17 orang siswa kelas VII-B MTs Negri 2 Bolaang Mongondow Selatan sebagai subjek penelitian. Penelitian ini dilaksanakan sebanyak dua siklus, yang masing-masing siklus terdiri dari perencanaan, pelaksanaan tindakan, observasi, dan refleksi. Teknik pengumpulan data dilakukan melalui instrumen lembar observasi guru dan siswa, serta tes hasil belajar. Pada siklus I data hasil observasi terhadap kegiatan guru dan siswa menujukkan rata-rata kriteria cukup baik (CB) dan hasil belajar siswa menunjukkan ketuntasan sebesar 64,7% dimana 11 dari 17 siswa yang mencapai nilai diatas KKM. Karena indikator keberhasilan tidak tercapai yakni minimal 80% maka penelitian dilanjutkan ke siklus II dengan beberapa perbaikan. Setelah melakukan perbaikan, pada siklus II diperoleh data hasil observasi terhadap kegiatan guru dan siswa sudah mencapai rata-rata kriteria baik (B) dan hasil belajar siswa juga menunjukkan peningkatan dimana 82,35% atau 14 dari 17 orang siswa telah berhasil mencapai nilai diatas KKM. Berdasarkan pernyataan tersebut, dapat disimpulkan bahwa model problem-based learning dapat meningkatkan hasil belajar siswa pada materi persamaan dan pertidaksamaan linear satu variabel.
