<![CDATA[This study aims to develop a valid, practical, and effective interactive E-Worksheets on matrix concepts contextualized within a tourism travel framework through a Deep Learning approach to enhance students' critical thinking skills. Employing a Research and Development (R&D) design based on the ADDIE model, the research involved Phase F students at SMK Dirgantara Putra Bangsa. Data were collected using expert validation sheets, student usability questionnaires, and critical thinking pretest-posttest instruments, then analyzed via paired-sample -tests and normalized gain ( ). The results demonstrated that the E-Worksheets achieved high validity, with expert scores reaching 71.00 for subject matter and 103.00 for media (Very Valid category). The practicality assessment yielded a mean score of 72.6 (Practical category). Furthermore, the intervention significantly improved students' critical thinking skills, increasing the mean score from 55.57 to 86.20 ( ) with an average of 0.69 (moderate-to-high level). In conclusion, the interactive tourism-contextualized E-Worksheets effectively optimizes smartphone utilization and transforms vocational mathematics learning into a meaningful, critical-thinking-driven experience.]]>
