According to the findings of the study, both Group A (the subtitle group) and Group B
(the no-subtitle group) had significant gains from pre-test to post-tests in the self-reported
Vocabulary Knowledge Scales. When the gains of two groups were compared, the
participants in Group A, who watched cartoons with subtitles, were found to improve a bit
more than those in Group B, who watched without subtitles (Group A= .34127, Group B=
.11111). However, there was no significant difference between groups in terms of gains.
Thus, what facilitated the improvement in vocabulary knowledge was not the incorporation of
subtitles into the cartoons. At this point, it might be posited that the cartoons increased the
vocabulary development of participants.
