Microteaching is a significant strategy in teacher education programs for giving student teachers opportunities to practice their teaching techniques.This study aims at investigating how using microteaching affects the teaching performance and attitude of Iraqi EFL student teachers. For this purpose, 30 Iraqi EFL student teachers were selected and then randomly assigned to two groups:control and experimental, 15 in each. To collect the data of the study, two instruments were used. The first one is a checklist used to measure student teachers' teaching performance; while the other is a questionnaire used to measure their attitudes toward microteaching. The study hypotheses state that the learners' mean scores in the post-administration of teaching performance checklist and microteaching attitude questionnaire for the two groups were not significantly different. The findings revealed that performance of the experimental group was significantly higher than that of the control group and that using the microteaching method was more rewarding than the traditional tutoring. Furthermore, microteaching as a training method was also viewed favorably by the participants in the experimental group.
