The present study investigated the effectiveness of integrating RCampus in EFL freshman classrooms on EFL students' reading and writing skills development. Forty-three freshman students majoring in translation participated in the study. Before instruction, the students were pretested. Then they received traditional in-class instruction that depended on the textbook, in addition to online extension reading and writing activities using RCampus (www.rcampus.com), an open source Online Course Management System. Each week discussion threads that required the students to search for information, read extra material and respond to questions in writing were posted. The students posted their own book summaries, discussion threads and comments on each other's posts. The pre and posttest scores were compared and the effect of utilizing RCampus on reading and writing skills development is reported.
