Abstract:
This study aims to investigate the use of cohesive devices in second language writing skills.it was found out that there were many elements which were a major reason behind the misuse of cohesive devices by students when they learn English language writing skills. A hundred students were chosen from first year at Sudan University of Science and Technology (males and females) as a sample. They were divided into two groups. A control group and an experimental group. The experimental group was given a test after they were taught the general principles of using cohesive devices in English language writing skill. The results of the marks showed that the students in the experimental group did better. The control group who were given a test directly without any teaching faced difficulties, When comparing the marks of the two groups in the pre and the post-tests it was clear that the students in experimental group did better .In addition, the statistical analyses emphasized the difference in the performance of the students marks of the two groups in the pre and post- tests. This means that there were statistically significant differences among the students before and after teaching them cohesive devices in second language writing skills. Statistical analysis also showed significant value (0.00) fewer than (0.5). Also the researcher used a questionnaire as a tool for the data collection of this study. The questionnaire was given to fifty Sudanese English language teachers from various Universities. Their answers supported the finding of the study . This means that there is a need to teach English language students the use of cohesive devises in second language writing skills.
