This comprehensive study delved into the nuanced exploration of the impact that TED Talks exert on the refinement of speaking skills among a cohort of 72 B.Tech engineering students, all navigating the intricacies of English as their second language. Employing a methodical descriptive qualitative approach, we meticulously conducted an analysis that juxtaposed the participants' speaking abilities before and after exposure to TED Talks for Control and Experimental groups. Behavioral theory is used in this study. The overarching objective of this research was twofold: firstly, to elucidate the discernible effects of TED lessons on the communication skills and confidence levels of students; and secondly, to pinpoint and evaluate the tangible enhancements in the participants' speaking proficiency. What emerged from the study was a consensus among the students regarding the transformative influence of TED-based activities on their listening skills, overarching communication competence, and levels of self-assurance. One salient revelation pertained to the positive correlation between engagement in TED Talks and an amplification of not just linguistic abilities but also the overall self-assurance and poise of the students. The integration of TED videos and multimedia emerged as a focal point, with participants highlighting these modalities as indispensable tools for infusing interest and enjoyment into the learning process.
