Both speaking tasks, oral interview and picture story narrative, were carried out after the end
of each school day in a laboratory room to avoid disturbance. They were asked to perform
each task individually. For the oral interview task, each participant was required to respond to
two sets of the predetermined questions within the defined time of 30 minutes. When the oral
interview task was completed, the picture story narrative was conducted. This task took about
3 minutes for each participant. All speech was audio-recorded and later transcribed for
analysis. After the completion of both types of speaking tasks, the researcher conducted the
retrospective interview which revealed students’ awareness of their CS use as well as their
perceptions of the effectiveness of each type of communication strategy.
