Abstract

The Purpose of this study is to find out what forms of conceptual construction errors experienced by students in solving mathematical problems and the appropriate form of scaffolding for each concept construction error experienced. This type of research is descriptive qualitative research. In determining the subject of this study using purposive sampling technique. The research subjects were students of class XII, the subjects of this study were 6 people which were then reduced to 2 people representing medium and low abilities. The instruments used in this study were test questions and interview sheets. The data obtained were analyzed by the steps (1) Reducing the data. (2) presenting data and (3) drawing conclusions. The results of this study are that S1 experienced more “correct” pseudo construction errors and mis-logical construction with the scaffolding provided, namely level 2 (reviewing, explaining and restructuring) while S2 experienced four types of errors with the scaffolding provided, level 2 scaffolding. each individual will be different because it must be adjusted to the actual development zone of each.

Abstract

Penelitian ini bertujuan untuk mengembangkan e-modul pembelajaran materi teorema Pythagoras yang mengintegrasikan pendekatan Realistic Mathematics Education (RME) dan memanfaatkan perangkat lunak 3D Pageflip Professional. Pengembangan e-modul ini dirancang untuk meningkatkan kualitas pembelajaran matematika, khususnya pada topik teorema Pythagoras yang seringkali dianggap abstrak oleh siswa. Pendekatan RME dipilih karena kemampuannya menjembatani konsep matematika abstrak dengan dunia nyata siswa, sehingga meningkatkan pemahaman dan relevansi materi. Penelitian ini menggunakan model pengembangan ADDIE (Analysis, Design, Development, Implementation, Evaluation). Data yang dikumpulkan bersifat kualitatif dan kuantitatif, dengan subjek penelitian siswa kelas VIII A SMP N 10 Muaro Jambi. Hasil penelitian menunjukkan bahwa e-modul yang dikembangkan memiliki kualitas yang sangat valid dari segi materi (95,7%) dan desain (89%). Aspek kepraktisan terbukti melalui penilaian guru (91,4%), uji coba kelompok kecil (87,9%), dan uji coba lapangan (83%). Keefektifan e-modul terefleksi pada hasil belajar siswa, di mana rata-rata siswa yang mencapai ketuntasan belajar adalah 80,9%. Temuan ini menegaskan potensi e-modul berbasis RME dengan teknologi visualisasi 3D dalam meningkatkan hasil belajar siswa pada materi geometri.
