Learning Tools with SAVI Participation (Somatic, Auditory, Visualization, Intellectual) in Improving Mathematical Communication Skills in the Industrial Revolution Era 4.0

Abstract

Mathematical Communication Capability becomes an important part of the purpose of learning mathematics in the current era, but in reality, mathematical communication is still underestimated so that the process of learning mathematics has not fully paid attention to mathematical communication competence. This study aims to examine the validity of the development of learning tools with the SAVI approach in improving mathematical communication skills. This type of research is the development of learning tools using learning development models using learning development models ADDIE models consisting of 5 stages. Learning Tools developed include (a) Syllabus, (b) RPP, (c) Modules, (d) Macromedia Flash 8 and (e) Mathematical communication skills test. Two class research subjects in which one class uses expository learning and one class using the SAVI approach. Analysis and discussion results show that the use of the SAVI approach can improve mathematical communication skills. This study was declared valid, based on the results of the validation of experts, for the syllabus (3.63), RPP (3.63), Modules (3.48), Macromedia Flash 8 (3.70) and tests of mathematical communication skills (3.67) is categorized as meeting the good criteria.
