<![CDATA[This study aims to describe: (1) the effectiveness of the problem-based learning model assisted by web-based interactive learning media reviewed from students' mathematical communication skills and self-awareness; (2) the effectiveness of the direct learning model is reviewed from students' mathematical communication skills and self-awareness; (3) a more effective learning model among the problem-based learning model assisted by web-based interactive learning media and direct learning is reviewed from the mathematical communication ability and self-awareness students. The study involved two classes: an experimental class and a control class. Class X MPLB 2 served as the experimental class, and Class X AKL 1 served as the control class, each consisting of 36 students. The data were obtained from the test results (pre-test and post-test) of mathematical communication skills, well as from non-test questionnaires measuring students’ self-awareness. The research was considered effective if the average score mathematical communication skills exceeded the criteria for achieving learning objectives (KKTP) at SMK Negeri 1 Tarakan, which was 75, and if the average self-awareness score students exceeded 84, which falls in the very high category. The data were analyzed using Hotelling’s T², one-sample t-test, and independent sample t-test. The results showed that (1) problem-based learning assisted by web-based interactive learning media was effective when viewed from students' mathematical communication skills and self-awareness; (2) ineffective direct learning reviewed from students' mathematical communication skills and self-awareness; (3) Problem-based learning assisted by web-based interactive learning media is more effective than direct learning reviewed from mathematical communication skills and self-awareness in students.]]>
