<![CDATA[Problem-solving ability is a crucial skill in mathematics learning. However, many elementary school students struggle with mathematical problem-solving, particularly on data presentation materials. This research aims to investigate the improvement of mathematical problem-solving abilities and student curiosity through the application of Guided Discovery Learning (GDL) with contextual approach support. This mixed-method research involved 44 respondents: 21 students from the experimental group (SD Negeri 2 Tunggulsari) and 23 students from the control group (SD Negeri 2 Sumur). The experimental group received learning using GDL with contextual approach, while the control group received conventional learning. Data were collected through pre-test, post-test, curiosity questionnaires, and interviews. Results showed that the experimental group achieved an average post-test score of 80.71 compared to the control group's 72.39 (t = 3.180, p = 0.003), with 86% of experimental group students achieving mastery. Additionally, student curiosity increased significantly from 47.62% to 79.52% after GDL implementation. The normalized gain score was 0.59 (moderate category), indicating that GDL with contextual approach effectively improved both mathematical problem-solving abilities and student curiosity. This research provides evidence that GDL with contextual approach is an effective alternative learning method for improving mathematics learning outcomes at the elementary school level.]]>
