The Effect of Explicit Instruction of Formulaic Sequences on Oral Proficiency Improvement of Young Iranian EFL Students

This study aimed to shed light on young Iranian EFL students’ oral proficiency improvement through explicit instruction of formulaic sequences (FSs). This pretest-posttest quasi experimental study was conducted in a bilingual school in Shahrekord, Iran. Accordingly, based on ACTFL OPI test, two groups of low intermediate students with age range of 11 to 12 were chosen to be assigned as control and experimental groups. The control group with 20 participants continued its regular instruction focusing on analytic grammar rules and discrete vocabulary, while the experimental group with 40 participants received explicit FSs-based instruction through readings, by adopting a teaching procedure inspired by Lewis’ prescribed strategies for lexicon instruction. After 24 sessions of instruction, the participants were interviewed again, and their oral performance was recorded and transcribed to be scored by two experienced judges. Subsequently, ANOVA results revealed the significant oral proficiency improvement of experimental group in comparison to the control group, pointing to the effectiveness of FSs instruction.
