Validity of Mathematics Learning Devices with a Sedekah Context to Enhance Mathematical Communication Skills and Awareness of No Poverty

Abstract

Education plays a crucial role in achieving the Sustainable Development Goals (SDGs), particularly through Education for Sustainable Development (ESD). Implementing ESD requires higher-order thinking skills, which are currently still low among Indonesian students. One important aspect of higher-order thinking is mathematical communication skills, which can be enhanced using the Problem-Based Learning (PBL) model. Sedekah is a part of charity in the Islamic perspective and is relevant to SDG Goal 1 on No Poverty. By implementing a PBL device about sedekah, it is hoped that both mathematical communication skills and awareness of No Poverty can be improved. This study aims to describe the validity of a mathematics learning device with the context of sedekah in enhancing students' awareness of No Poverty and their mathematical communication skills. The learning device includes teaching modules, student worksheets, and learning outcome tests. This research is a developmental study, especially validation test. The research instrument is a validation sheet for the learning device. The learning device was validated by seven experts. The results showed that the validated learning device achieved a valid category, with an average score of 4.5 for the teaching module, 4.4 for the student worksheets, and 4.3 for the mathematical communication tests. Based on these results, it can be concluded that the mathematics learning device with the context of sedekah for enhancing students' mathematical communication skills can be used for the next development stage.
