<![CDATA[Algebraic derivative functions are among the mathematics topics that are often considered difficult by students because they require a strong conceptual understanding, accuracy in calculations, and the ability to apply derivative rules in problem-solving. On the other hand, the rapid development of digital technology provides opportunities to develop more interactive and flexible learning media through the utilization of smartphones. Therefore, this study aims to develop mathematics mobile learning media integrated with Articulate Storyline 3 on the topic of algebraic derivative functions and to determine its validity, practicality, and effectiveness in learning. This study employed the Research and Development (R&D) method using the ADDIE development model consisting of analysis, design, development, implementation, and evaluation stages. The subjects of this study were eleventh-grade senior high school students. Data collection techniques included expert validation questionnaires, teacher and student response questionnaires, as well as pretest and posttest instruments. The results showed that the developed mobile learning media met the criteria of being valid, practical, and effective for mathematics learning. Media expert validation obtained a percentage of 92.28% and material expert validation obtained 92.25%, both categorized as very valid. Teacher responses obtained 92.50% and student responses obtained 84.72%, indicating that the media was highly practical and easy to use. In addition, the effectiveness test showed an N-Gain score of 0.70 categorized as effective, indicating an improvement in students’ learning outcomes on algebraic derivative functions. Therefore, the integration of Articulate Storyline 3 in mathematics mobile learning can support interactive, flexible, and student-centered learning processes]]>
