Development of Learning Media Based on Realistic Mathematics Learning Approach Assisted by Macromedia Flash to Improve Students' Mathematical Reasoning Ability at MTs Negeri 1 Langsa

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.
