In this context, the overall effect size on students' academic achievement was analyzed with the CMA program using subject area and grade level moderator variables. In the second part, content analysis was performed using the ATLAS.ti program for 8 studies selected for the meta-thematic analysis. it was found that immersive virtual reality environments had a positive, moderate (d = 0.526) effect on students' academic achievement.
