Abstract This study aimed to assess the attitudes and perceptions of EFL students toward the use of CALL programs and their perceived view on an online writing system that was developed in the present study by means of a questionnaire as well as an asynchronous discussion forum. An online writing system was developed and a sample of 30 English-as-a-Foreign-Language (EFL) learners, studying at Sharif University of Technology in Iran, was assigned to the study. The CALL attitudes of the participants were assessed by a CALL questionnaire, which indicated that Iranian students attached a high value to CALL. Moreover, the comments of the participants that were posted on a discussion forum were analyzed with the aid of Henri's framework (1992), which revealed the presence of certain concepts and themes within the views of learners toward the use of computers in their educational settings.
