The use of social–emotional learning (SEL) practices in online literature teaching has not yet been sufficiently researched. This study addresses this lacuna by identifying SEL practices mentioned by lecturers and preservice teachers (PSTs) as they reported on their respective experiences of teaching and learning in online literature lessons. Data were collected using three research tools: questionnaires were completed by 28 lecturers from four different teacher education colleges and 90 PSTS; semi-structured interviews were held with 12 of the literature PSTs; and a focus group was held with six lecturers. A data analysis revealed six major SEL-related themes mentioned by lecturers and PSTs as essential practices of online learning and teaching: building relationships, working collaboratively, emotional involvement, effective communication, dealing with conflicting feelings, and techno-pedagogic skills. These findings contribute to our understanding of online learning and teaching versatility and complexity. Considering these findings in light of existing theoretical models demonstrates that while five themes coincide with the skills included in the CASEL model, the sixth theme regarding techno-pedagogical skills is not part of the original model. These findings expand the applicability of the CASEL model from its original face-to-face learning context to the interaction between learners and lecturers in an online platform.
