This study examined the role of e-formative feedback in emergency remote teaching and learning for first-year student teachers. Numerous scholars have acknowledged the pedagogical value of formative feedback in teacher education. However, there is a pressing need for significant improvement in the quality and accessibility of e-formative feedback provided to student teachers in online learning environments. This study explored the nature of e-formative feedback, technological challenges, and pedagogical practices employed by teacher educators when implementing formative assessment in emergency remote learning contexts. The study is underpinned by Interactive Tutoring Feedback model as the theoretical framework. We utilised the interpretive paradigm and a qualitative approach, specifically employing a case study methodology as a means of inquiry. The empirical investigation involved 20 first-year student teachers selected purposively from a large public university in South Africa. Data were collected through semi-structured interviews and analysis of learning management system logs, with thematic analysis employed to analyse the data. The findings revealed that meaningful e-formative feedback could have been enhanced by addressing contextual factors such as limited internet connectivity and a lack of familiarity with online learning platforms. While student teachers valued the quality of e-formative feedback, they expressed concern regarding their ability to consistently access and engage with feedback to improve their learning in the isolated online environment. This paper recommends providing both student teachers and teacher educators with the necessary technological support and training to effectively utilise e-formative feedback and enhance student teachers' academic achievement and professional development during emergency remote learning.
