This study explores EFL graduate students’ attitudes toward and emotions about the teacher and peer feedback using a questionnaire and interviews. Throughout their advanced writing course, students were provided with feedback via Google Docs, which they then systematically arranged within their Google Drive-based e-portfolios. The interview findings confirmed that students had mixed attitudes and emotions toward e-portfolios. They expressed negativity toward the timing of peer feedback reception and its validity. However, they showed a positive attitude toward teacher feedback and the importance of maintaining the integrity of a Google Drive portfolio. Emotionally, the students felt frustrated due to feedback focus, anxious while providing feedback, confused by ambiguous comments by peers, and embarrassed by their errors. However, their confidence was bolstered by their adeptness with technology and the interactive functions of Google Docs served as a motivating factor. Additionally, the t-test results comparing pre-test and post-test questionnaires showed statistical significance, indicating that students improved their compositions’ content, organization, and language with the assistance of peer and teacher feedback. The study underscores the importance of integrating technology into writing instruction, considering students’ emotions and attitudes. Thus, ongoing efforts are vital to develop the technological skills of both teachers and students.
