This quasi-experimental study scrutinized the impact of technology-mediated TBLT in an online collaborative and individual EFL learning environment on the development of request production of 20 male and female B.A. students of TEFL. The participants were divided into two equal individual and collaborative experimental groups to receive online video-prompt task-based instruction on request speech act production in six distinct situations defined based on different contextual variables including distance, power, and imposition. Two similar versions of video-prompt Discourse Completion Tests (DCTs) focusing on six situations covered in online classes were given to the participants as a pretest and posttest. The results indicated that both groups’ request speech act production improved significantly after the intervention. However, there was no significant difference between the performance of the two groups. It was then concluded that both techniques are facilitative in boosting students’ pragmatic competence; however, more time is required to find out the extent to which these techniques differ in terms of their productiveness.
