Abstract
This study aimed to assess the validity, practicality and effectiveness of Android media based on a realistic approach to improve students' mathematical problem-solving and critical thinking skills. The research adhered to the Plomp & Nieveen Development model, which consists of a preliminary, development or prototyping, and assessment stage. The findings from Trial I and Trial II indicate that the developed Android media based on a realistic approach meets the requirements of being valid, practical, and effective. Furthermore, the application has improved the problem-solving and critical thinking skills of the students who used it. The N-gain value for problem-solving skills in trial I was 0.55, which increased to 0.60 in trial II, indicating a medium level of improvement. The N-gain value for mathematical critical thinking skills in trial I was 0.63, which increased to 0.67 in trial II, also indicating a medium level of improvement.
