Abstract

Pemahaman konsep matematis dan tanggung jawab merupakan aspek penting dalam pembelajaran Kalkulus, namun mahasiswa masih mengalami kesulitan dalam memahami konsep. Penggunaan Padlet sebagai media kolaboratif ditawarkan untuk mendorong partisipasi aktif. Penelitian ini bertujuan untuk menganalisis kemampuan pemahaman konsep matematis dan tanggung jawab pada pembelajaran dengan Padlet. Metode penelitian menggunakan kualitatif dengan strategi studi kasus. Data diperoleh dari mahasiswa mata kuliah Kalkulus Integral di Program Studi Pendidikan Matematika, Universitas Islam Nusantara melalui wawancara, observasi, dokumentasi, dan angket. Teknik pengolahan data: pengumpulan, reduksi, penyajian, dan penarikan kesimpulan. Hasil menunjukkan mahasiswa belum memenuhi seluruh indikator kemampuan pemahaman konsep matematis; M1 dan M5 hanya memenuhi satu indikator, sementara M2 tidak memenuhi satupun. Sebaliknya, tanggung jawab meningkat, ditunjukkan oleh konsistensi M5 serta peningkatan M1 dan M2. Padlet menumbuhkan tanggung jawab, tetapi perlu dioptimalkan dengan menambahkan fitur diskusi aktif yang lebih terstruktur untuk mendukung ketercapaian kemampuan pemahaman konsep matematis. Mathematical concept understanding and responsibility are crucial in Calculus learning, yet students often struggle with these concepts. The use of Padlet as a collaborative media is offered to encourage active participation. This study aims to analyze the ability to understand mathematical concepts and responsibility in learning with Padlet. The research method used is qualitative with a case study strategy. Data were obtained from students of the Integral Calculus course in the Mathematics Education Study Program, Universitas Islam Nusantara, through interviews, observations, documentation, and questionnaires—data processing techniques: collection, reduction, presentation, and conclusion. The results indicate that students have not met all the mathematical concept understanding ability indicators. Specifically, M1 and M5 meet only one indicator, while M2 does not meet any. In contrast, responsibility increases, indicated by the consistency of M5 and the increase in M1 and M2. Padlet fosters responsibility, but it needs to be optimized by adding more structured active discussion features to support the achievement of understanding mathematical concepts.

Abstract

Pembelajaran geometri di sekolah sering kali bersifat abstrak dan kurang memanfaatkan sumber belajar kontekstual yang dekat dengan kehidupan sehari-hari siswa. Padahal, warisan budaya memiliki potensi besar sebagai media pembelajaran matematika yang menghubungkan konsep geometri dengan nilai-nilai lokal. Penelitian ini mengkaji konsep geometri dalam arsitektur Museum Sultan Mahmud Badaruddin II Palembang serta potensinya sebagai sumber belajar etnomatematika. Menggunakan pendekatan kualitatif dengan metode etnografi yang dimodifikasi, penelitian dilakukan melalui lima tahap utama: eksplorasi awal dan identifikasi informan, pengumpulan data lapangan, dokumentasi visual dan kontekstual, analisis data, serta interpretasi etnomatematis. Data dikumpulkan melalui observasi, wawancara semi-terstruktur, dan dokumentasi visual, dianalisis dengan pendekatan domain dan taksonomi, serta diverifikasi melalui traingulasi sumber. Hasil menunjukkan elemen arsitektur museum, memuat konsep bangun datar, bangun ruang, kesebangunan, simetri, dan transformasi geometri yang terintegrasi dengan nilai budaya lokal. Temuan ini merekomendasikan integrasi museum dalam PjBL dan kurikulum berbasis kearifan lokal untuk meningkatkan keterlibatan siswa, identitas budaya, dan kompetensi guru. Geometry learning in schools often remains abstract and makes limited use of contextual resources that are closely connected to students’ daily lives. Cultural heritage holds significant potential as a medium for mathematics instruction, linking geometric concepts to local values. This study examines the geometric concepts embedded in the architecture of the Sultan Mahmud Badaruddin II Museum in Palembang and explores its potential as a learning resource within an ethnomathematics framework. Employing a qualitative approach with a modified ethnographic method, the research was conducted in five main stages: initial exploration and informant identification, field data collection, visual and contextual documentation, data analysis, and ethnomathematical interpretation. Data were collected through observations, semi-structured interviews, and visual documentation, analyzed using domain and taxonomic approaches, and verified through source triangulation. The results indicate that the museum’s architectural elements contain concepts of plane figures, solid figures, similarity, symmetry, and geometric transformations, all integrated with local cultural values. The study recommends integrating museums into PjBL and local wisdom-based curricula to enhance student engagement, strengthen cultural identity, and improve teachers’ competencies.
