This study aims to investigate how students perceive teacher feedback on Google Docs. The data was collected from one of the language study skill courses for graduate students taught by one of the instructors in the Department of Language Studies at King Mongkut's University of Technology Thonburi. The six participants of the study, the first-year graduate students of the MA Programme of English for Professional and International Communication, were required to write four short writing tasks as assignments. Two out of the four of the students' short writing tasks with teacher feedback on Google Docs were analyzed. The stimulated recall interviews were used to ask the participants about the perceptions towards using Google Docs to give feedback by the teacher. The results show that every participant understood the teacher feedback on Google Docs. They also had positive attitudes towards using Google Docs in giving feedback. Reasons of their satisfaction were also reported. However, the participants also revealed the problems of using Google Docs in giving feedback. Discussion and implications of using Google Doc in teaching and learning were provided in the final part.
