As more various types of computer-assisted language learning (CALL) programs have been incorporated into language classrooms over the recent decades, it has become more important to uncover whether, to what extent, and under which moderator variables CALL can be yield more effective outcomes than traditional language instruction. The issue of education is one of the most important materials addressed by technology. Instead, meta-analysis is a statistical and quantitative method that leads us to a general conclusion by integrating the results of different researches. In this study, researchers worked on the impact of educational technology in English language teaching by studying 67 articles and theses (from 1000 studies that were relevant in title and abstract). All articles and theses were included from 2009 to 2020 and 7 articles were excluded from this study due to insufficient information. Furthermore, two instruments, SPSS (mainly its sub-branch Kruskal-Wallis test) and CMA were used to calculate and evaluate data in this research. The total effect size calculated for studies under both fixed and random models was statistically significant and also the study of effects by year of publication, instruments used in research and research methods showed that their effect size was significant. Teaching English with the help of technology has an effective effect size and has shown the success of this technology in language learning.
