This study investigates the integration of Zuvio Blended Literature Circle in English language instruction, focusing on enhancing learning motivation and self-efficacy among lower-intermediate students in large classrooms. The quasi-experimental research involved 105 university students over a semester, using mixed methods. Quantitative findings showed significant improvements in learning motivation (average scores rising from 75.07 to 81.91, p<0.001) and self-efficacy (scores increasing from 90.11 to 94.70, p<0.001). Qualitative data revealed enhanced classroom dynamics, with students showing greater initiative and supportive peer interactions. The incorporation of both expository and narrative texts enriched linguistic input and prompted discussions on various themes. Results indicate that the Zuvio Blended Literature Circle effectively addresses instructional challenges in large-class settings, significantly boosting students' motivation and self-efficacy in language learning. This study provides valuable insights for improving English education in similar contexts.
