Validity and practicality of elementary linear algebra teaching materials based REACT to improve mathematical communication and problem solving skill

Abstract

Most student learning outcomes in Elementary Linear Algebra (ELA) are unsatisfactory. ELA courses are defined by the fact that they contain interrelated and abstract concepts that require proof. One of the causes of the problem is that students have been unable to see the connections between concepts, apply them to problems, and learn through discussion groups. The purpose of this study was to determine the validity and viability of ELA teaching materials based on the REACT strategy for enhancing students' mathematical communication and problem-solving abilities. The research method used is R & D, which involves developing and testing a specific product. The study collected data using validity and practicality test sheets. A descriptive statistical analysis technique was used to analyze the data. The research concluded that REACT-based ELA instructional materials are both valid and practical.
