摘要:This paper investigates the effect of Computer-Mediated Technology (CMT) on the writing proficiency skills of English learners at the secondary level. Due to the vast usage of computers, their role in the field of education cannot be neglected. This wide scope of computers has motivated researchers to use it in the field of education. A country like Pakistan is a developing country, and here, still traditional methods of teaching have been used, whereas developed countries are using Computers in the field of education. This research is conducted to find out the impact of computer-mediated technology in enhancing ESL learner's proficiency in writing skills in the Pakistani context. The study especially looked into to what extent CMT gives positive feedback from learners in improving their ESL writing skills proficiency level in Secondary public schools. This study also aimed to motivate teachers towards the use of CMT in the EFL classroom. This study is based on a quasi-experimental model. In this study, two groups of ESL students have been set. Both groups consist of 30 English learners. One Group is a Controlled Group, and the other is the Experimental Group. The controlled group is treated with traditional teaching methods, and the Experimental Group is treated with CMT technology. It is eight weeks of treatment. After successful treatment, it is observed that the experimental group has performed significantly better than that of the control group. ESL learners, treated with CMT, secured better scores as compared to the controlled group, which proved that the use of CMT in ESL classroom is helpful in the teaching-learning process..
