Abstract:
This research investigated the effectiveness of Video-Based Learning (VBL)
using TED Talks in enhancing speaking skills among English as a Foreign
Language (EFL) learners, addressing challenges such as limited vocabulary,
pronunciation difficulties, lack of practice, and speaking anxiety. The study was
conducted at SMA N 4 Kisaran, North Sumatra, Indonesia, and involved 60 Class
XI students, selected via purposive sampling and divided into experimental (n=30,
taught with VBL) and control (n=30, taught with textbooks) groups. Data were
collected through pretest and posttest speaking assessments and analyzed using
SPSS version 27.0 with descriptive and inferential statistics, including an
independent t-test. Results showed that the experimental group significantly
outperformed the control group (t=23.98, p<0.05), with a 31.39% improvement in
fluency, pronunciation, vocabulary, and confidence, compared to 14.81% for the
control group. These findings highlight VBL’s efficacy in overcoming speaking
challenges, offering educators a valuable tool for EFL instruction.
