<![CDATA[This research aims to create a Student Worksheet grounded in a scientific methodology, augmented by PowerPoint, to enhance students' capabilities in mathematical comprehension. The study utilized a Research and Development (R&D) methodology, specifically the ADDIE framework. The participants in the study comprised 30 students. Data collection methods included interviews, expert validation, student feedback questionnaires, and assessments before and after the intervention. The viability of the media was assessed utilizing a Likert scale, whereas the effectiveness of learning was evaluated through the normalized gain (N-gain). The findings revealed that the LKPD attained 80% for content and 82% for, which are classified as highly feasible. Responses from students in the limited and extensive trials scored 85% and 84%, respectively, reflecting extremely favorable feedback. Student learning outcomes increase in mean score from 62 to 80.15, along with a rise in classical mastery from 40.67% to 80.27%. The N-gain score of 0.71 was deemed high. These results indicate that the LKPD is valid, practical, and effective in improving students' mathematical understanding and educational outcomes in matrix topics.]]>
