This study investigated the responses of two groups (n = 85) of EFL learners toward their experience with extensive reading in a three-month EFL college reading class in which two novels (narrative) and fourteen expository texts were the main reading text. Using a three-part survey questionnaire and the follow-up interviews, this study attempted to examine (1) the factors attributed to a successful extensive reading program, and (2) the EFL readers' preferences regarding the classroom activities for reading extensively. The analysis of frequency of responses indicated that no single factor was chosen by the students and there was a discrepancy between learners with different proficiency levels and learning backgrounds. Some pedagogical implications and limitations were also discussed.
