This study investigated the effect of Computer Assisted Language Learning (CALL) on elementary-prep school students' improvement in English as a foreign language (EFL). Eightythree students in Al-Tamayoz Elementary-prep School, United Arab Emirates, were selected and divided into experimental and control groups (43 and 40 participants respectively). Results of Analysis of variance (ANOVA) showed a significant difference between CALL users and nonusers in favor of the experimental group (p less than < .05). In addition, a questionnaire was administered to CALL users to investigate their attitude, perceived utility, and intention to use CALL in the future. Students in the experimental group had a positive attitude toward CALL, perceived its utility for helping them learn EFL, and had a strong intention to use it in the future. Results of this study have provided evidence of the effect of CALL on learning English as a foreign language. Implications and recommendations for future research are presented.
