Mathematics Learning Innovation with Ethno-Based Sttep-W (Structured Think-Talk-Evaluate-Presentation-Write) Model: Efforts to Improve Students' Mathematical Connection Skills

Abstract

Having mathematical connection skills in learning mathematics is important, but students' mathematical connection skills are still relatively low. The results of modifying the development of the think-talk-write learning model, namely the Ethno-based STTEP-W learning model, are expected to influence students' mathematical connection skills positively. This study aims to describe the quality of the Ethno-based STTEP-W learning model and its developed devices that include valid, practical, and effective criteria for improving the mathematical connection ability of junior high school students. This research uses the research and development (R&D) method. The learning model development procedure used in this study is the development model, according to Nieveen and Plom, consists of three stages: preliminary research, prototyping phase, and assessment phase. The subjects in this study are junior high school students in grade VII and SMP Negeri 1 Tanara mathematics teachers. It is carried out in the even semester of the 2023-2024 academic year for triangular and quadrilateral subjects. The data in this development research are qualitative and quantitative. The analysis is carried out for validity, practicality, and effectiveness. The results of the study prove that the Ethno-based STTEP-W (Think-Talk-Evaluate-Presentation-Write) learning model developed is valid, practical, and effective in improving students' mathematical connection skills. The components of the STTEP-W learning model can improve students' mathematical connection skills during mathematics learning. Ethno-based mathematics learning mathematics applied in the Ethno-based STTEP-W model also shows that mathematics is not only limited to abstract concepts and formulas that are difficult to understand but also as a living and relevant tool in daily life.
