Computer-Assisted Language Learning (CALL) has gained increasing acceptance since it provides learners with abundant resources. Most researches confirm the beneficial effect of CALL on English as a Foreign Language (EFL) learners' cognitive, metacognitive, and affective developments. However, the diversity of students' intelligence is associated with different language learning needs. The study aimed to compare the effect of CALL on gifted and non-gifted EFL adolescents' English proficiency and their perceptions of CALL. The study included 20 EFL seventh graders with similar English proficiencies. Six were recognized as gifted and fourteen were non-gifted with reference to their IQ score in the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV). Participants received 8-weeks of the VoiceTube online learning programme. A mixed method was employed to analyze the data obtained from General English Proficiency Test (GEPT) scores, learning logs, questionnaires, and interviews. The result revealed the gifted students' English reading and listening proficiency outperformed the non-gifted ones in the post-test. They were motivated and enthusiastic in challenging themselves with "I"+1 online learning material. By contrast, most non-gifted students held passive attitude toward CALL and doubted its effectiveness for their exams. Some felt anxious about the miscellaneous online learning materials. CALL should be an enhancement, not a replacement, in balance with conventional instruction. [For full proceedings, see ED564162.]
