Abstract
This research aims to: Analyzing the validity, practicality, and effectiveness of learning tools oriented towards problem-based learning models assisted by macromedia flash that was developed to improve students' mathematical literacy skills. there is an increase in students' mathematical communication skills by using learning devices based on realistic mathematical approaches that were developed in trial I and trial II by 6.74; 3 and there is an increase in students' mathematical literacy skills by using learning devices based on realistic mathematical approaches that were developed in trial I and trial II by 5.68. Keywords : Development of Learning Tools, based on Realistic Mathematical Approaches, Communication Skills and Mathematical Literacy DOI: 10.7176/JEP/11-14-16 Publication date: May 31 st 2020

Learning is one of the most important elements in the implementation of education
According to Hasratuddin (2015: 27) mathematics is a means or way to find answers to problems faced by humans, a way of using information, using knowledge about shapes and sizes, using knowledge about counting, and the most important thing is to think in humans themselves to see and use relationships
The mathematics learning goals set by the Ministry of National Education are in line with NCTM (2000: 67) which sets five competencies in mathematics learning: mathematical problem solving, mathematical communication, mathematical reasoning, mathematical connections, and mathematical representation
Summary
Learning is one of the most important elements in the implementation of education. The importance of creating quality education means the same as creating quality learning, especially mathematics learning. The mathematics learning goals set by the Ministry of National Education are in line with NCTM (2000: 67) which sets five competencies in mathematics learning: mathematical problem solving (mathematical problem solving), mathematical communication (mathematical communication), mathematical reasoning (mathematical reasoning), mathematical connections (mathematical connections), and mathematical representation (mathematical representation). These skills are high order mathematical thinking skills (high order mathematical thinking) that are important to be developed by students in the mathematics learning process. According to Sumarmo (Hodiyanto, 2017) describe the communication skills that must be built students include communication skills that connect real objects, pictures, tables and diagrams into mathematical ideas and explain mathematical ideas orally or in writing in daily life into mathematical symbols
