Abstract

Penelitian ini bertujuan untuk menghasilkan dugaan lintasan belajar (Hypothetical Learning Trajectory) yang dapat membantu siswa memahami konsep jarak dimensi tiga menggunakan software Geogebra 3D. Penelitian ini menggunakan metode design research tipe validation study. Pendekatan STEM dengan konteks sains. Subjek penelitian adalah siswa Kelas XII SMA Sriwijaya Negara. Pengumpulan data dilakukan melalui observasi, membuat rekaman video tentang aktivitas kerja kelompok, mengumpulkan hasil kerja siswa, memberikan tes awal dan tes akhir, dan mewawancarai siswa. Data dianalisis secara restropektif. Hasil penelitian menunjukkan bahwa lintasan belajar yang diperoleh dapat membantu siswa dalam memahami konsep jarak dimensi tiga, yaitu memahami konsep jarak titik ke titik sebagai langkah awal pemahaman konsep phytagoras, menemukan makna dari jarak titik ke garis dengan proyeksi berbantu software Geogebra 3D, membuat sketsa yang memuat di dalamnya posisi titik, garis, dan bidang berbantu software Geogebra 3D. Penggunaan fitur Augmented Reality (AR) yang terdapat pada software Geogebra 3D dalam pembelajaran jarak dimensi tiga dengan pendekatan STEM dapat membantu siswa memahami konsep jarak dimensi tiga serta dapat membuat siswa lebih aktif dalam pembelajaran di kelas.

Abstract

Mastery of concepts is necessary for students in learning geometry, particularly in the topic of flat-sided 3D spatial structures. A strong grasp of concepts is achieved through non-routine problem-solving exercises, which are an integral part of problem-solving-based learning. According to the OECD (Organisation for Economic Co-operation and Development) of Education and Skills 2030, problem-solving-based learning is considered an important component in the curriculum of 60% of countries worldwide. The use of digital media is an innovative approach in education that can transform abstract geometric forms into real-world situations. The focus of this research is to develop digital media to enhance conceptual understanding among eighth-grade students at Yosowinangun Junior High School. The outcome of this study is a valid, practical, and effective digital learning medium for improving conceptual understanding. The research adopts the ADDIE model as the methodological framework. The research sample consists of twenty eighth-grade students. Data collection instruments include validation sheets, practicality questionnaires, interviews, and tests. The research findings indicate that the learning media is valid based on the analyzed validation sheets. Furthermore, the learning media is considered practical based on student response questionnaires, with an average score of 83.3%. The learning media also has a potential effect on conceptual understanding, as evidenced by the overall test results falling into the good category with an average score of 74.75%. Therefore, problem-solving-based digital learning media becomes an effective tool to assist students in developing their conceptual understanding in the process of learning flat-sided 3D spatial structures in geometry.
