Enhancing English Vocabulary Retention Among Iranian Trainee Teachers Through Literature-Based Interactive Input-Output Tasks

To surmount the obstacles a deficient productive vocabulary retrieval places in the way of EFL teachers, the current study sought to ascertain whether or not involving trainee teachers in interactive input-output activities enhance their vocabulary retention. To this end, a convenience sample including ۴۹ Iranian EFL trainee teachers were recruited to take part in a quasi-experimental pretest-posttest-delayed posttest study. Having been grouped into three comparison groups, the participants were exposed to the same literary texts; however, the differential treatment of the study entailed three different interaction modes (individual, collaborative, and collaborative-cooperative) and two types of input / output processing (non-reciprocal and reciprocal). A repeated measure analysis of covariance (RM ANCOVA) was performed on the participants’ achievements in the pre- post- and delayed posttest measures and the results revealed that the two groups involved in literature-based interactive (collaborative and collaborative-cooperative) reciprocal input-output activities showed significantly higher levels of vocabulary retention compared to the group exposed to literature-based individual non-reciprocal input-output tasks. Additionally, contributing to significantly higher levels of long-term retention, the collaborative-cooperative mode of interaction was found to be more effective than the collaborative one. The findings corroborated the need for including literature-based interactive input-output tasks in EFL teacher training curriculum.
