This article seeks to provide a comprehensive review of panel discussions, focusing on the procedures for conducting them and the advantages of incorporating them as a teaching tool in the ESL classroom. Despite the limited existing literature on the use of panel discussions in educational settings, this review aims to shed light on the potential benefits of this approach. Panel discussions offer numerous advantages when employed as a teaching strategy in ESL classrooms, particularly in enhancing students' speaking skills and promoting active engagement. The benefits of utilizing panel discussions in ESL instruction are manifold and warrant further exploration. This teaching method can be particularly beneficial for ESL students as it encourages collaborative learning, fosters critical thinking, and improves communication skills. By engaging in panel discussions, students have the opportunity to express their thoughts, listen to diverse perspectives, and develop their speaking abilities in a supportive environment. Moreover, the Zone of Proximal Development theory proposed by Lev Vygotsky provides a theoretical framework for understanding the effectiveness of panel discussions in the ESL classroom. This theory emphasizes the importance of scaffolding and peer interaction in facilitating learning and cognitive development. By leveraging the Zone of Proximal Development, educators can optimize the use of panel discussions to create a dynamic and interactive learning environment that enhances students' language proficiency and overall academic growth.
