The researcher created Text Detective, a special online computer application that administered communicative and non-communicative text-based tasks. An experiment conducted using the program found that both task types lead to significant gains in language development and that there was no difference in absolute gains between tasks. However, there was a significant difference in productive vocabulary learning efficiency in favor of the communicative task (Hughes, 2023a). An analysis of the communication revealed that context-elaborative question formulation correlated significantly with vocabulary learning efficiency even for questions that were not responded to. This suggests that the process of forming the questions themselves led to the gains in efficiency (Hughes, 2023b).
