The study aimed at investigating the impact of using Edmodo on improving writing skills of the middle school pupils. To fulfill the purpose of the study, the instrument was constructed (an EFL writing test). The instrument was administered before and after the experiment to measure the students' level. The validity and reliability of the study instrument was established before their use in the study. The quasi-experimental design had been adopted in the study. The participants of the study consisted of 28 pupils of eighth graders at Adwaa Alhedaya International Schools, in the kingdom of Saudi Arabia, where 14 pupils represented the experimental group and 14 represented the control group. Edmodo was implemented with the experimental group, whereas the control group received the regular teaching. Results of the study revealed that practicing EFL writing through Edmodo led to significant improvement in students  writing skills. Therefore, it was concluded that using Edmodo as a mean of communicating and practicing the English language was highly effective in improving the participants' performance.
