One of the objectives that must be met in the realm of education is undoubtedly the significance of mathematical literacy. Nonetheless, Indonesian students' mathematical literacy has fallen short of expectations; in other words, their literacy levels remain inadequate. This goal now influences e-worksheets designed to help students become more proficient in mathematical literacy. Investigate This is a quasi-experiment based on design research. Through N-Gain test phases, prerequisite tests, and t-tests, analysis helped e-worksheet GeoGebra improve students' mathematical literacy abilities using the Problem Based Learning (PBL) approach in the major discussion comparative trigonometry class X. We may infer that students who use e-worksheets develop their mathematical literacy abilities more than students in the class that does not use e-worksheets since the t-test's mark significance (2-tailed) is little from 0.05, which is 0.000. © 2026 Author(s).
