Feedback practices for students' speaking activities in an online environment are very different from those on-site. This study investigated online feedback practices for speaking skills in a Sino-UK joint-venture university, as well as teachers and students' perceptions of the practices. Semi-structured interviews were conducted with four teachers and 11 students on a discipline-specific English for Academic Purposes (EAP) course. Overall, e-feedback was perceived as less effective than face-to-face feedback, which was mainly due to a lack of interpersonal ties. A range of specific e-feedback types was used; each type elicited both positive and negative perceptions, which were influenced by the nature of feedback type, opportunities for communication and psychological issues. This study concludes that for e-feedback to have the equal potential for clarifying expectations as face-to-face feedback, practitioners need to be well informed of the features of different types of e-feedback, and carefully choose the most appropriate type according to the learning outcomes and students' preferences. Students also need to develop an e-feedback literacy to fully use such feedback.
