Mira Ananda. (2026). The Validity of Learning Videos to Develop Senior High School Students' Computational Thinking Assisted by MATLAB. Undergraduate Thesis. Universitas Syiah Kuala. Under direction by Prof. Dr. Rahmah Johar, S.Pd., M.Pd., and Mukhlis Hidayat, S.Pd., M.Kom. Computational thinking (CT) has emerged as a crucial 21st-century skill; however, the instruction of quadratic functions in secondary education often remains conventional and characterized by rote formula memorization. Furthermore, the integration of computational tools such as MATLAB into mathematics learning media for senior high school students remains significantly underdeveloped. This study aims to develop and evaluate the validity and readability of MATLAB-assisted educational videos on quadratic functions oriented toward students' CT skills. Employing a Research and Development (R&D) methodology based on the Plomp model, the scope of this study was limited to the preliminary research and prototyping phase. The developed products consist of three educational videos integrating the core components of CT into the topics of parabolic properties, transformations, and sketching graphs of quadratic functions. Product evaluation involved three expert validators and a readability test conducted with three senior high school students representing heterogeneous academic capabilities. The results demonstrated that the educational videos achieved a high level of validity, with an average score of 85.72%. Additionally, the readability test indicated that the media was well-understood by students across all academic levels, requiring only minor adjustments to the audio quality. In conclusion, the developed educational videos are verified as valid and highly suitable for deployment as an alternative mathematics learning resource to support the cultivation of secondary students' computational thinking skills.
