RBL-STEM Learning Activity Framework: The Development of Paving Block Decorations Using Local Antimagic Coloring Techniques in Improving Students' Conjecturing Thinking Skills

The ability of conjecturing thinking skill is very important in the industrial era 4.0. Conjecturing skills are to make strong guesses or predictions on problem solving. This also strongly related generalizing from a specific truth broad truth. Therefore this study, Research-Based Learning model which integrated with STEM approach (Science, Technology, Engineering, Mathematics) will be applied solve paving block decorations. Students introduced application form local antimagic coloring techniques. next step how bring solving learning class, then developed RBL and tools improve students’ skill. Base it shows that elaborated four elements considered breakthrough applying RBL-STEM classroom decoration problem.
