Abstract

This study aimed to determine the effectiveness of the Problem-Based Learning (PBL) model assisted by Flashcard media on students’ mathematical literacy and to examine students’ participation in solving problems presented through Flashcard media. The study employed a Pre-Experimental Design with a One Group Pretest-Posttest design. The research subjects were 22 tenth-grade students of the Building Modeling and Information Design (DPIB) program at SMK Negeri 5 Medan. The research instruments consisted of an essay test to measure mathematical literacy and an observation rubric to assess student participation, both of which had been validated. The results showed that the average mathematical literacy score increased from 71.82 in the pretest to 80.23 in the posttest. The hypothesis test yielded t-count > t-table, or 16.54 > 2.079, indicating the effectiveness of the Problem-Based Learning model assisted by Flashcard media on students’ mathematical literacy. The observation results showed an average student participation score of 3.46, categorized as very active, with the highest score in the cooperation aspect at 3.60. Thus, the implementation of PBL assisted by Flashcard media can improve mathematical literacy while encouraging active student participation in the learning process.
