A large part of what instructors to at university is give feedback on the written work of students. This is particularly true for those teaching languages and the process of reading and responding in writing a time-consuming process. The feedback given can concern aspects of language proficiency, sentence structure, grammatical correctness and lexical choice. Feedback is often given on content and textual issues such as paragraphing, effectiveness of arguments and level of critical analysis. As teachers, we hope that he feedback will result in an improvement in the student's revised work but also other subsequent written work. This paper investigates how one cohort of ESL univeristy students experience teacher feedback. The responses of this questionnaire-based survey show that students appreciate the feedback they get but do not always understand what it is they are expected to to.
