Abstract:
The primary objective of this research was to examine and compare the impacts
of two distinct web-based platforms on the instruction of vocabulary to English as a
Foreign Language (EFL) learners. This study was planned to be carried out in two
classes (46 students). The participants were selected using convenience sampling. Data
were collected from students attending the English preparatory program at the
Bahcesehir University preparatory campus located in Kemerburgaz, Istanbul. They
both took pre- and post-vocabulary achievement tests before and after a period of
treatment. The findings of the study indicated that there was no statistically significant
difference in the performances of the two groups during the pre-tests. However, after
the students utilized the two online platforms and underwent post-tests, the results of
the independent samples t-test (p < .05) revealed a significant difference between the
two groups favoring Kahoot over Educaplay. In addition, exploring the probable effect
of gender on vocabulary learning revealed that the male participants of the study had
a better performance on measures of vocabulary learning compared to the female ones.
