Effect of Audiovisual Aids on Learning at IELTS Coaching Center: A Quasi-Experimental Study

Abstract

The main objective of this quasi-experimental study is to explain the effect of audiovisual aids on learning at IELTS Coaching Centers, Vehari City, Pakistan. YouTube lectures on Reading comprehension for IELTS were used as a treatment for the experimental group. There were thirty-two students in each group: control and experimental group. Two reading comprehension tests from the IELTS Cambridge book were used as instruments to collect data from participants. A semi-structured interview was conducted with the experimental group to measure their preferences and perceptions of using YouTube lectures to improve reading comprehension. The results of both paired and independent samples t-tests showed a significant effect on the experimental group, with a mean score p-value < 0.05 indicating improvement. Qualitative data was thematically analyzed. The study found that YouTube lectures significantly improved the mean score of the experimental group, indicating a positive impact on their reading comprehension.
