This study aimed to investigate the instructor's electronic feedback practices during the COVID 19 pandemic in terms of the nature of the content of e-feedback, the formulation, the challenges, and the multimodal nature of the instructor's e-feedback. This study used a qualitative case study to obtain data from the instructor's e-feedback in three linguistic courses as delivered, practiced by the single English language instructor. The instructor's e-feedback via Blackboard and WhatsApp platform and the follow-up interview were analyzed qualitatively. The findings indicate that: (1) the highest number of instructor's e-feedback focused on global issues as compared to local issues; (2) the instructor composed his e-feedback in the form of eight main categories: explanations, suggestions, clarifications, questioning, repetitions, statements, praises, and commands; and (3) the instructor used more screencasts for providing e-feedback, followed by written and audio modes respectively. The thematic analysis (4) revealed the instructor's positive impression on providing e-feedback through these interactive modes (written, audio, and screencast) and a range of challenging issues such as students' preference issues, technical issues, timing issues, financial and areal issues. This study is significant because it provides us with a comprehensive picture of the patterns of the feedback content, the formulation of the e-feedback, the multimodality of the instructor's e-feedback, and the significant issues that emerged from the instructor's e-feedback practices. However, further research should include a relative group of instructors to determine the impact of e-feedback on learners.
