Examining the effectiveness of using online activities in learning english vocabulary

The study aims to examine the effectiveness of online activities on the performance of the vocabulary test. Forty seven students studying in intact classrooms participated in the study: twenty four in the experimental group and twenty three in the control group. An independent t-test was administered to compare between the two groups. The finding indicated that the experimental group obtained higher marks in the vocabulary post-test (M=4.2, SD=1.98) than the control group (M=2.84, SD=1.6) and the difference between the two groups was statistically significant (p=.014). Furthermore, a paired samples t-test was conducted for the experimental group and the findings suggested that on average participants in this group performed significantly greater in the post-test (Mean=4.18, SD= 1.99) than in the pre-test (Mean= 1.4, SD=1.13), p<.001. These findings showed that using supplementary online activities had improved vocabulary acquisition for EFL learners.
