Abstract

This study aims to analyze the improvement of Higher Order Thinking Skills (HOTS) through mathematics learning on the Three-Dimensional Geometry topic in Grade XII of Yayasan Pendidikan Al-Fattah Medan. HOTS is a crucial aspect of 21st-century education because it helps students develop critical, creative, logical, and reflective thinking skills in addressing complex problems. In the context of mathematics learning, particularly in spatial geometry, mastering HOTS not only supports students in understanding abstract concepts but also in applying them to real-life situations. This study employed a descriptive qualitative method with instruments consisting of a pre-test, post-test, and an open-ended questionnaire to explore students’ understanding and learning experiences. The findings revealed a significant improvement, where the average pre-test score of 7 increased to 52.21 in the post-test. This result highlights that the implementation of HOTS-based learning strategies is effective in enhancing students’ comprehension of distance, angles, and point positions in space, while simultaneously strengthening their analytical, evaluative, and creative abilities. The study implies the importance of adopting innovative learning strategies oriented toward HOTS development to improve the quality of mathematics education and prepare students for global challenges.

Abstract

This study aims to analyze misconceptions of the Pythagorean Theorem found in the Grade VIII Junior High School/Islamic Junior High School Mathematics textbook (Kemdikbud, 2022) and to compare them with the correct mathematical concepts. The research method used is qualitative with a content analysis approach, in which data were collected through document review of concept explanations, illustrations, examples, and exercises related to the Pythagorean Theorem. The results of the study reveal potential misconceptions, including the assumption that the Pythagorean Theorem applies to all types of triangles, a lack of clarity in identifying the hypotenuse as the longest side opposite the right angle, and students’ tendency to memorize Pythagorean triples without understanding the mathematical logic behind them. Comparison with the correct concepts shows that these misconceptions stem from insufficient conceptual emphasis, limited use of illustrations, and examples that focus more on procedures than on understanding. These findings indicate the need for improvements in the presentation of textbook material by adding emphasis on the conditions of right-angled triangles, the definition of the hypotenuse, and detailed explanations of Pythagorean triples. Thus, this study is expected to provide input for teachers and textbook authors in designing more conceptually oriented mathematics instruction, so that students’ understanding of the Pythagorean Theorem becomes more accurate and in-depth.

Abstract

Indonesia sedang memasuki fase bonus demografi yang memberikan peluang besar sekaligus tantangan bagi pembangunan nasional. Namun, masih terdapat kesenjangan keterampilan antara lulusan perguruan tinggi dengan kebutuhan industri yang dapat menghambat pemanfaatan peluang tersebut. Penelitian ini bertujuan untuk mendeskripsikan strategi adaptasi mahasiswa Universitas Negeri Medan dalam menyongsong bonus demografi, mengidentifikasi tantangan yang dihadapi, serta menelaah keterampilan, peran organisasi, dan kewirausahaan sebagai bentuk kesiapan mahasiswa. Metode penelitian yang digunakan adalah deskriptif kualitatif dengan subjek 15 mahasiswa FMIPA UNIMED yang dipilih secara purposive. Data dikumpulkan melalui angket terbuka Google Form dan dianalisis menggunakan teknik analisis tematik. Hasil penelitian menunjukkan bahwa mahasiswa melakukan adaptasi melalui peningkatan literasi digital, penguasaan bahasa asing, pengembangan soft skills, serta keterlibatan dalam organisasi, seminar, magang, dan kewirausahaan. Tantangan yang dihadapi mencakup persaingan kerja, keterbatasan lapangan pekerjaan, kesenjangan keterampilan, serta kendala internal seperti manajemen waktu dan kesehatan mental. Keterampilan abad 21 berupa kombinasi hard skills dan soft skills dinilai sebagai bekal utama, sedangkan organisasi kampus dan kewirausahaan berperan penting dalam menyiapkan mahasiswa agar mampu bersaing sekaligus menciptakan lapangan kerja. Penelitian ini menyimpulkan bahwa mahasiswa Universitas Negeri Medan memiliki kesadaran adaptif yang tinggi, meskipun masih diperlukan perluasan penelitian dengan lingkup yang lebih besar untuk memperoleh gambaran yang lebih komprehensif.
