Research Based Learning and STEM Learning Activities: The Use of R-Dynamic Coloring to Improve the Students Meta-literacy in Solving a Tessellation Decoration Problem

Abstract

The meta-literacy ability is very important in today's life, especially living in the disruptive technology era. Meta-literacy is an ability that goes beyond metacognition and technological literacy. However, the students’ meta-literacy ability is still relatively low. One of the causes of the low ability is due to the learning model that has been applied so far has not been able to bring out this ability. Therefore, in this study, an RBL learning model that is integrated with the STEM approach will be applied in solving the r-Dynamic coloring problem. By r-dynamic coloring, we mean a proper k-coloring c of G if for every vertex v ∈V (G) satisfies |c(N(v))| ≥ min{r,d(v)}. The minimum k such that G has an rdynamic coloring with k colors is called an r-dynamic chromatic number, denoted by ��(�). By using the r-dynamic coloring technique, we will improve students' meta-literacy in solving the tessellation decoration problem. Therefore, in this research, the syntax of learning activities of the Research-Based Learning and STEM approach will be developed including the assessment indicator of the meta-literacy ability.
