Providing written feedback is a time-consuming part of an English teacher’s work life and there are many ways in which feedback can be provided. According to the Swedish National Agency of Education (2011), teachers must provide their students with feedback. Studies have been conducted investigating feedback provision and teachers’ feedback practices, but few studies have shed light on the students’ perception of feedback, especially in Swedish, and even Nordic, contexts. This study investigated students’ perception and use of teacher feedback on written assignments in an EFL (English as a foreign language) classroom in mid-Sweden. The study investigated both student perception of feedback, with specific focus on WCF (written corrective feedback), and students’ use of the feedback. The method used for data collection was a semi-structured internet survey containing 21 questions. The participants were 30 upper secondary school students. The results of the study showed that students mostly perceived feedback as important and useful, especially when it contained concrete tips and proposals for text improvement. They regarded CF and WCF as important as they wanted to become aware of what errors they made to avoid making those in future writing. Nevertheless, they reported that too extensive feedback (unfocused CF) was not preferred. Both positive and negative feedback were considered useful for future writing and a large majority read the feedback they received every time. Feedback provided together with a grade was also read by the students, as they wanted to have information about strengths and weaknesses in the text as well as motivation for the grade. To conclude, feedback was mostly perceived as important and useful, and the students used it to improve their writing.
