Chapter 7. Isolated and combined effects of models and corrective feedback in the acquisition of the Turkish locative morpheme

Abstract

This study investigated the relative effects of models, corrective feedback, and a mixed treatment including both models and corrective feedback in the development of the Turkish locative morpheme. Native speakers of English were assigned to one of four conditions: models, corrective feedback, mixed, or control. Participants performed one input-based and one output-based task with a native Turkish speaker and received treatment according to their group assignments. Learners’ performance was measured through a multiple-choice task and an oral picture description test once immediately after the treatment and once two weeks after the treatment. Results showed that the mixed treatment in which learners received models first and then corrective feedback was the most effective treatment.
