The recent improvements in technology and their integration in language learning have played a facilitating role in vocabulary acquisition. Quizlet, an online teacher-/student-friendly tool, is one of the leading applications in vocabulary acquisition. Along with the effectiveness of visualization in acquiring vocabulary, humor has been also extensively indicated to carry a significant role in language learning. With all its facilitating features, the integration of technology, humor, and vocabulary can be achieved via Quizlet. In this study, the visual integration of humor accompanying vocabulary on Quizlet was taken into scrutiny to see to what extent humor-integrated pictures on Quizlet account for the retention of vocabulary acquisition. With this purpose, this study examined the effect of humor-integrated pictures on vocabulary acquisition of 45 intermediate English as a foreign language (EFL) learners on Quizlet. In so doing, the experimental group received a series of unknown vocabulary items for which the integrated pictures were humorous, while the vocabulary items assigned for the control group were identical, but in non-humorous contexts. At the end, an independent samples t-test applied on the scores achieved from a posttest indicated a significant difference in scores of the control group and that of the experimental group. In fact, the learners in the experimental group significantly outperformed their counterparts in the control group. The results indicated that linking vocabulary items with humorous pictures is more effective than using non-humorous context in learning vocabulary. Apparently, as the results indicate, the significant effectiveness of technology in vocabulary learning can be boosted with the help of humorous context. The findings shed light on the importance of technology in language learning and its linking with humor in vocabulary learning.
