Student enrolment at the tertiary level in Bangladesh is increasing to support the rapidly emerging economy.
Due to limited budget allocation, insufficient infrastructure support, and a high teacher-student ratio, class sizes
have expanded significantly, raising a serious pedagogical issue: conventional lecture-based approaches,
commonly used in Bangladeshi contexts, are failing to meet students' demands for conceptually rich, complex
subjects like Physics, leading to rote learning, limited conceptual understanding, and a decline in student interest.
Considering the limitations of the Bangladeshi tertiary-level college system, this study explores the prospect of
Interactive Lectures (IL) as a paradigm-shifting approach for large Physics classes. This study highlights a
significant gap in pedagogical practice in Bangladesh by critically reviewing the existing international literature
on IL methods, including technology-enhanced Audience Response Systems (ARS), interactive lecture
demonstrations, and peer instruction. Through a critical examination of current teaching practices and contextual
challenges, including examination-driven curricula, inadequate infrastructure, and excessive faculty workload,
the author proposes an integrated action plan that includes pre-class, in-class, and post-class activities using
available technologies. The study concludes that, despite systematic challenges, implementing IL can create a
more active student-centered learning environment potentially reversing the trend of disengagement in science
