This study aims to investigate the perceptions of Omani senior English teachers and teachers towards the role of postlesson discussion in developing teachers. The study findings illustrated that both SETs and teachers hold a positive
attitude towards the importance of feedback in developing effective teachers and that cooperation governs the
relationship between them during feedback sessions. Also teachers play an active role in the lesson discussion and they
themselves decide on future goals. Indeed; all participants think that feedback is useful for their development; hence –
like SETs – they make valuable suggestions about making post-lesson discussion more beneficial and more effective
