Using extrinsic motivation as a reward system offers a way to motivate students in educational settings. It is also a boundless teaching method to encourage students’ motivation in class. Since March 2020, Indonesian students and universities have undergone massive learning changes without being prepared. After the COVID-19 Pandemic, most universities had to change to online teaching and learning. This research examines how extrinsic motivation is practical and applicable in an educational setting. If the students do not have internal drives, extrinsic motivation, such as rewards, is needed to strengthen the students’ behaviors. The study adopts the case study method (Gerring, 2004). In addition, the researcher focused on the effectiveness of extrinsic motivation. Lecturers performed individual check-ins with 18 students for six weeks. They observed lecturers and students to investigate students’ perceptions of extrinsic motivation in their English classes. Results showed that extrinsic motivation can motivate students to participate actively in their English classes and to practice English inside the classroom during online learning. It also created active types, showing that almost all the students raised their hands to participate and seemed to study English harder. Thus, using extrinsic motivation made the teaching and learning process run effectively.
