Abstract

Metaliteracy is the framing and strengthening of information literacy based on critical and creative thinking. Metaliteracy indicators include generating, combining, using, participating, sharing, and collaborating. To implement higher-order thinking skills, we implement research-based learning with a STEM approach. To develop the students’ metaliteracy, educators should also equip the learning process by learning materials. In this study, we developed RBL-STEM learning materials to improve students' metaliteracy skills. The learning materials that have been developed are considered to be valid, effective, and practical. The validity score obtained in each materials is 3.5 for the Lesson Plan, 3.54 for the Student Worksheet, and 3.63 for the Learning Outcomes Test.

Abstract

Irregular coloring is a proper coloring and each vertex on a graph must have a different code. The color code of a vertex v is  where  and    is the number of vertices that are adjacent to v and colored i. The minimum k-color used in irregular coloring is called the irregular chromatic number and denoted by . In this paper, we discuss the irregular chromatic number for the bull graph, pan graph, sun graph, peach graph, and caveman graph.
