A cover letter is a pedagogical tool to elicit useful feedback within writing groups. From research conducted on participating students in Estonia as part of a postdoctoral research project funded by Estonian Research Council PUTJD1121, this instructional artefact gives instructor and student guidance on how to write a useful cover letter to elicit desirable peer feedback. The guide contains three sections: (i) Facilitator guidelines, (ii) student guidelines, and (iii) instructions for a reflective group workshop to improve cover letter practices.
