Speaking proficiency development in EFL classrooms: measuring the differential effect of TBLT and PPP teaching approaches

Abstract

Abstract This paper outlines a classroom-based study on the timing of explicit language instruction. It also provides an alternative to the CALF (Complexity Accuracy Lexis Fluency) framework for analyzing learner language, which may not always be appropriate for EFL contexts. Two groups of learners, assigned to either a TBLT or a PPP condition, completed a speaking task. A follow-up task was given three months later, but with no explicit language focus for either group. Data from these interactions were analyzed for use of target grammar structures and overall speaking proficiency. Results suggest that explicit introduction of language through PPP benefits immediate task performance, but that ultimately post-task focus on language through TBLT leads to greater language development. The framework for analysis was effective in showing differences in performance between the groups in this context.
