Abstract: Computer Assisted Language Learning (CALL) is as an approach to language teaching and learning in which the computer is used as an aid to the presentation, reinforcement and assessment of material to be learned, usually including a substantial interactive element. Recent researches have shown that human language is much more complex than it was previously thought. Many literatures are proving that the use of information and communication technology in language learning has several potential advantages. The major concern of this survey study is to determine the acceptability of Computer-Assisted Language Learning Software (CALLS) in teaching Mandarin as perceived by the students and teachers. CALL software was examined in terms of (1) instructional design, (2) program instructions, (3) program transition, (4) user interface, (5) user control, (6) phase control/branching and (7) error handling. The assessment of acceptability of the CALLS in teaching Mandarin was achieved using the five-point Likert scale with corresponding description. The overall means 4.48 and 4.45 which were obtained from the students and teachers’ evaluation respectively, both has the descriptive interpretation of “highly acceptable”. Both the students and the teachers expressed that the computer-assisted language learning software facilitated learning and that they desire to use CALLS for various Mandarin topics.
