To inspire college students’ English learning motivation, this study proposed to combine Project-Based Learning (PBL) with ZUVIO online teaching platform. The traditional teaching methods focus on teachers’ direct instruction in class, which mean that students only receive knowledge from teachers instead of formulating the answers on their own. This also decreases interaction in the classroom and prevents students from collaborating with other peers. However, implementing PBL and ZUVIO would allow students to apply knowledge in the social context and work with their classmates. In this study, two freshman English classes in a private university in central Taiwan were chosen as the sample. The students in both classes were low-level students (CEF A2 level). One class (N = 39) was chosen as the experimental group which had to complete the PBL tasks assigned by the teacher and use peer assessment function in ZUVIO for one academic year. The other class (N = 43) was chosen as the control group which was given the traditional teaching instructions. The results showed that the experimental group performed better on the midterm exam compared to the control group during both semesters (p = 0.001). Additionally, the results of the questionnaire showed that students’ motivation to learn English increased when using PBL and ZUVIO as teaching methods.
