The present paper studies a blended learning approach provided by a university in central Taiwan from 2018 to 2020. In this approach, a Moodle E-learning platform called iLearn2.0 was used along with an onsite classroom. iLearn 2.0 has four major features, including cloud services, mobile learning, flipped classroom, and data analysis. The platform was used during 2018–2020 in the Citizen Participation course, helping the researcher/teacher to design an interactive course content and aiding students to complete classroom activities through their devices. In total, 127 students enrolled in citizen participation courses were taught during 2018–2020, using different teaching methods. In 2018, students studied in a physical classroom. iLearn2.0 was integrated with the physical classroom for the 2019 course; lastly, the iLearn2.0 platform was used alone in 2020. To evaluate the effect of virtual teaching on the students’ performance, the researcher used summative assessment as the dependent variable. The findings show that the class that received the iLearn2.0- assisted teaching had a significantly better learning performance than the other two classes. However, when researchers used iLearn2.0 alone, both the scores and the feedback from students were lower than those in blended and face-to-face teaching. The results suggest the effectiveness of iLearn2.0 assistance, while learners’ performance did not show any significant change in a totally online class. Results were assessed in the view of sustainability, and three sustainability dimensions were found to be improved in the hybrid classroom. The researcher suggests that iLearn2.0 be integrated with other learning tools for maximum results, as it allows students to have a more diverse learning experience, strengthen sustainable learning, and grasp the progress of their courses and learning activities in a timely manner.
