The South Sumatera Songket Motifs for Supporting Students' Proving Process in Learning Reflection

This study addresses the limited use of the South Sumatera Songket motifs for supporting students’ proving process in the learning of reflection material. It aims to determine the role of South Sumatera Songket Motifs in students’ proving process in reflection learning. The study employed a validation approach within the Design Research framework, involving 30 students from one public junior high school in Palembang. The validation study comprised three stages: preparing for the experiment, the design experiment (including a preliminary teaching experiment and a teaching experiment), and retrospective analysis. Activities in the experiment included: 1) introducing the Songket motifs and having students identify lines of symmetry, 2) guiding students to reflect on the motifs using various axes, 3) engaging students in proving the congruence properties of the reflected motif, and 4) conducting group discussions to refine their reasoning and articulation of geometric concepts. The activities were designed using indicators adapted from Habermas’ Construct of Rationality to support the proving process in reflection material. The results from the learning experiment indicate that the provided questions support students’ proving process, guiding them from visual recognition to mathematical reasoning through structured activities.
