The primary goal of this study was to investigate the usefulness of computer-mediated, conversation-based tasks,
more specifically trialogue-based tasks, as a means of language assessment. The reported study provided initial
evidence that students engaged with the interactions that were built into the trialogue-based tasks as anticipated, and
that the students’ experiences with the trialogue-based tasks were generally positive. In this section, implications of
the results of the usability study are discussed from the following perspectives: (a) the representation of language use
tasks in non-assessment situations, (b) potential construct-irrelevant factors, (c) the collection of formative
information, and (d) the provision of meaningful communication opportunities for students with limited exposure to
English communication.
