The Effect of Input-based Instruction on the Speaking Ability of Iranian EFL Learners

Abstract

This study is an attempt to test the effect of input-based instruction on the speaking ability of Iranian EFL learners. To do so, fifty female EFL learners were selected from a whole population of eighty based on an IELTS interview and were randomly assigned into an experimental group and a control group. The participants in the experimental group received input-based instruction while the participants in the control group received. The mean scores of groups on the post-test were compared through an independent samples t-test which led to the rejection of the null hypothesis. The results showed that the students who received input -based instruction outperformed the other students in the control group. This led to the conclusion that input-based instruction influences total speaking ability of EFL learners. Course designers and language teachers can benefit from the results of study.
