ABSTRACT

By reviewing a range of related studies, this article has illustrated the internal validity of controlled trial (CT) design and randomised controlled trial (RCT) design in evaluating computer assisted second language learning. It has also provided a range of explanations for why RCTs are so rare in this topic area. The RCT is the most robust method of assessing effectiveness in terms of its prestigious internal validity. Nevertheless, this is not to deny the merit of quasi-experimentation, especially in evaluating computer assisted second language learning. A quasi-experiment, relaxing some aspects of control, may still yield valuable information and enable a researcher to answer some specific question arising from second language teaching experience.
