According to the results of the covariance analysis test, it was concluded that there is a significant difference between the three variables in the two stages of pre-test and post-test, which shows the effect of environmental training with the application of Eitaa social network on all of the three dimensions of the students' environmental attitude. The comparison of the mean of the two stages of pre-test and post-test showed that the mean of all of the three variables in the post-test was higher than the pretest.
