Development of Learning Tools Based on RBL and STEM on The Topic of Rainbow Vertex Antimagic Coloring

Abstract

The goal of this research is to produce RBL and STEM-based mathematics learning aids on the topic of Rainbow Vertex Antimagic Coloring. This type of research is referred to as R&D. (Research and Development). The goal of this research is to produce learning tools based on the Thiagarajan model, usually known as the 4-D model (four D model). This study creates mathematical learning aids, specifically LKM based on RBL and STEM on the topic of rainbow vertex antimagic coloring. Expert validation results show that the resulting LKM is valid, practical, and effective. Overall, the study's findings indicate that the learning tools developed are useful.
