The aim of this study was to investigate the effects of various ONLINE techniques (word reference, media, and vocabulary games) on READING comprehension as well as vocabulary comprehension and production. For this purpose, 60 language learners were selected and divided into three groups, and each group was randomly assigned to one of the treatment conditions. In the first session of treatment, a vocabulary test was administered as the pretest of the study. During treatment, the language learners in those three groups were instructed through ONLINE vocabulary games, ONLINE media along with transcript and ONLINE word reference. At the end of the treatment, a READING comprehension test, a vocabulary comprehension, and a vocabulary production test were given as the posttests. The collected data were analyzed using three one-way ANOVA procedures. The results showed that the ONLINE media group outperformed the other groups. Based on the findings of this study, it can be concluded that different ONLINE tools may have differential effects on learning different aspects of language. This implies that adhering to any single ONLINE tool may not necessarily bring about desirable results. The conclusion to be drawn from this is that teachers need to make use of a combination of these tools.
