摘要:The present study aimed at investigating the effect of using e-mail on developing EFL writing skills among first year experimental secondary school students. The study followed a pretest-posttest experimental-control group design. The study sample consisted of 60 students from Fakus Experimental Secondary School and was divided into two groups: 30 students for the experimental group and 30 students for the control group. For identifying the most important EFL writing skills required for first year experimental secondary school students, a writing skills list were developed .Then, a pre-post e-mail-writing skills test, free-writing test and a rubric for scoring the tests was developed. Students in both the experimental and control group were pre-tested using the e-mail-writing skills test and the free-writing test. Then, students of the experimental group were taught through the program of e-mail and writing and students of the control group were taught in the traditional method. Finally, students in both groups were post-tested using the same instruments. The study showed that; first, the experimental group outperformed the control group in the post-test of e-mail-writing skills test and the post- test of free-writing. Second, there was statistically significant difference between the mean scores of the pre-post e-mail writing skills test and the pre-post free-writing test of the experimental group at 0.05in favor of the post-tests. This difference can be attributed to using e-mail .Hence, it was concluded that the program of e-mail and writing proved to be highly effective in developing first year secondary school students' EFL writing skills
