The aim of this study was to investigate the effects of group-based consultations on pre-service primary school teachers' English teaching competence. Twenty nine pre-service teachers in groups of four or five received two rounds of consultations on their micro-teaching demonstrations from two native English instructors. The consultation procedure was three steps: preparation, micro-teaching observation and feedback. The self-evaluation checklists and micro-teaching evaluations were analyzed quantitatively to find how much improvement between the first and second micro-teaching had been made. The results indicated that consultations helped the pre-service teachers to improve their English teaching competence in general. The comments written by the consultants and the pre-service teachers about their micro-teaching observations were examined qualitatively. The results showed that consultations enabled the pre-service teachers to realize the strengths and weaknesses in their teaching behavior. Also, the observation of peer teaching and group discussion helped them to gain useful teaching skills and insights on what a good English lesson should be like.
