Abstract
This research aims to: (1) To determine the validity, effectiveness, and practicality of learning media assisted by Macromedia flash; (2) To analyze whether the learning media assisted by Macromedia Flash based on the RME approach is able to improve the mathematical reasoning abilities of class VIII students at MTs Negeri 1 Langsa. This research includes development research. This research uses Thiagarajan 4-D development model. This research was carried out at MTs Negeri 1 Langsa in the even semester of the 2020/2021 academic year. The subjects in this study were students of class VIII-2 MTs Negeri 1 Langsa. The results of this study indicate that: (1) the developed learning media has met the criteria of being valid, practical, and effective; (2) Increasing students' mathematical reasoning abilities using learning media developed on cube and block material, the average value increased from trial I of 69,5 to 77,08 in trial II.

Highlights
One of the characteristics of the progress of a nation can be seen from the progress in the field of Science and Technology (IPTEK)
Analysis of the validity of the mathematics learning media assisted by Macromedia Flash that was developed was seen from two aspects of the assessment: a) Assessment of learning media experts/practitioners b) Assessment of experts/practitioners of mathematics learning materials
The macromedia flash-assisted mathematics learning media developed in this study is said to be practical if the scores obtained from the practicality test questionnaire filled out by students have a practicality score of at least 76% in the practical category
Summary
One of the characteristics of the progress of a nation can be seen from the progress in the field of Science and Technology (IPTEK). According to the National Research Council (NRC), people must be familiar with the basic concepts of science, mathematics, engineering, and technology in order to think critically about the world and make intelligent decisions on personal and societal issues. From this we can see that mathematics has an important role in developing science, resources and advances in science and technology. According to Hasratuddin [2], the vision of mathematics education today is mastery of concepts in mathematics learning that are used to solve problems. The vision of future mathematics education is to provide opportunities to develop a mindset, self-confidence, beauty, objective and open attitude
