A country’s education quality is reflected in students’ learning outcomes, which require both a strong learning process and high motivation. In the 2022 PISA test, Indonesia ranked 69th out of 80 countries, highlighting the urgent need to improve learning quality and student motivation. This study investigates how project-based learning can improve students’ motivation and learning outcomes. Using Classroom Action Research (CAR) in two cycles, the study employed pre-tests and post-tests to assess learning outcomes and questionnaires to measure motivation. Results showed improvements in five of seven motivational aspects, including interest in English and enjoyment in learning. Students’ average scores increased from 54 to 62.28 in the first cycle and from 76.28 to 80.57 in the second cycle, surpassing the KKM (Kriteria Ketuntasan Minimal). These findings indicate that project-based learning successfully enhances students’ motivation and learning outcomes.
