<p>Penelitian ini bertujuan untuk menghasilkan lintasan belajar pada materi sifat-sifat segitiga berdasarkan panjang sisi dan besar sudutnya menggunakan konteks Stadion Gelora Sriwijaya Jakabaring di kelas VII. Desain pembelajaran yang digunakan terdiri dari tiga tahap yaitu <em>preliminary design, design experiment (pilot experiment </em>dan <em>teaching experiment), </em>dan <em>retrospective analysis</em>. Dalam penelitian ini, serangkaian aktifitas pembelajaran didesain dan dikembangkan berdasarkan pendekatan PMRI. Penelitian ini melibatkan 29 orang siswa kelas VII SMP Negeri 2 Indralaya Utara. Penelitian ini menghasilkan <em>Learning Trajectory</em> (LT) yang memuat serangkaian proses pembelajaran dalam 3 aktifitas yaitu menentukan jenis-jenis segitiga berdasarkan panjang sisi dan besar sudutnya, hubungan panjang sisi dan besar sudut pada segitiga dan menyelesaikan masalah yang berkaitan dengan sifat-sifat segitiga berdasarkan panjang sisi dan besar sudutnya. Hasil dari percobaan pembelajaran menunjukkan bahwa konteks Stadion Gelora Sriwijaya Jakabaring dapat digunakan sebagai <em>starting point </em>pada materi segitiga di kelas VII SMP.</p><p><em>This </em><em>research</em><em> aims to produce a learning </em><em>trajectory</em><em> on the material properties of triangles based on the side and angle using the context Stadi</em><em>on Gelora Sriwijaya Jakabaring</em><em> in class VII.
