Purpose: Despite the increasing use of technology-driven multimodal pedagogies in second-language writing education, there is a dearth of studies investigating the value and design of multimodal text feedback. Based on Chong's (Chong, S. W. 2019. "College Students' Perception of e-Feedback: A Grounded Theory Perspective." "Assessment & Evaluation in Higher Education" 44 (7): 1090-1105. https://bibliotheek.ehb.be:2102/10.1080/02602938.2019.1572067) tripartite conceptualization of written feedback, this article examines the effectiveness of the multimodal text feedback approach by exploring its influence on the technical, socio-emotional, and personal aspects of feedback. Design/methodology/approach: The study was conducted in a second-tier university in southeastern China. The researchers collected 57 participants' responses to a questionnaire survey regarding the effectiveness of multimodal text feedback and then conducted semi-structured interviews with 17 participants. Findings: Qualitative and quantitative analysis confirms multiple positive impacts of multimodal text feedback, such as improving technical features of students' writing and enhancing teacher-student relationships. Originality/value: The findings not only inform language-writing instructors with regard to the process-based design of multimodal text feedback but also lead to the proposal of a comprehensive conceptual framework for evaluating the interplay between different aspects of feedback.
