A comparative analysis of the impact of two pedagogical approaches on the production of idiomatic expressions among EFL learners

The ongoing debate surrounding the effectiveness of instructional models, particularly within the context of English as a Foreign Language (EFL) education, underscores the need for empirical investigation. This study sought to address this discourse by examining the differential impact of two pedagogical approaches on the production of idiomatic expressions. Employing a quasi-experimental design, the research compared the performance outcomes of two groups of learners, one exposed to deductive instruction and the other to inductive instruction. The participants engaged in a comprehensive exploration of 64 English idiomatic expressions over the course of the study. Data collection included a pre-test, eight immediate post-tests, a delayed post-test, and an open-ended questionnaire. The 20-session experiment, integrated seamlessly into the regular classroom instruction, involved the alternation of deductive and inductive approaches in teaching eight idiomatic expressions per session. Findings revealed significant improvements in both groups’ scores, yet a noteworthy distinction emerged in favor of the inductive instruction. This outcome implies that an inductive pedagogical approach may exert a significant influence on the production of idiomatic expressions among EFL learners. The study contributes insights into the ongoing pedagogical discourse and underscores the potential benefits of adopting inductive strategies in the teaching of idiomatic expressions.
