ABSTRACT
Purpose. Project-based learning (PBL) is a student-centered environment that emphasizes a dynamic classroom approach. It is founded on the idea that students gain a deeper understanding by actively tackling difficulties and issues from the real world. Students gain knowledge in a subject by devoting a significant amount of time to researching and solving a challenging question or interesting issue. Methods & Procedure. PBL was used in online classes during the pandemic of COVID-19. The study concentrated on projects that were created by students themselves under the guidance of teachers with the aim of determining their impact on their communication, engagement, motivation, and academic accomplishment in L2 acquisition context. The sample of the study that consisted of 100 EFL college students deployed this methodology in their weekly lectures. Results. The results show that PBL can have some positive effect on the entire spectrum of parameters under consideration as well as have a substantial impact on communication, engagement, motivation, and academic performance in online education. The findings clearly show that PBL can be a useful methodology for L2 acquisition and can provide students with various challenging activities and topics that increase their motivation and engagement, and thus, academic achievement. © The Author(s) 2023.
