Purpose: The previous coronavirus disease 2019 (COVID-19) pandemic has forced pre-service English teachers to conduct their teaching simulation virtually. In the context of online teaching, social presence is vital for effective learning. This skill is perceived as a way to humanize the online learning process. This article explores how social presence is represented in the pre-service teacher's synchronous online classroom and how the development of social presence enables the pre-service teachers to develop their students' well-being and thus humanize online classrooms. Design/methodology/approach: The current study draws upon case study research. The data were collected from (1) synchronous online teaching simulation recordings of pre-service English teachers from the Language Classroom Management course and (2) interview transcripts from three participants. Both data sources were transcribed, coded and analyzed. A two-step coding scheme for pre-service English teachers' social presence was adapted from the Community of Inquiry (CoI) coding template. Findings: This study reports that all the three social presence categories (i.e. cohesive, affective and interactive) emerged from their online teaching simulation. In addition, the development of social presence to humanize online classrooms from the pre-service teachers was found in these stages: (1) having a role model for teaching, (2) showing respect and being friendly and (3) adjusting the language of instructions to the students' level. Research limitations/implications: This study has been limited to the pre-service teachers in one university only. Therefore, this needs to be tested in wider settings and contexts. Practical implications: Theoretically, this study has added students' well-being as the element that connects social presence to the humanizing online classroom. Meanwhile, practically, in relation to teacher education, this paper also recommends the teaching stages leading to a more humanized online learning. Originality/value: Current studies tend to describe social presence in experienced teachers' asynchronous online classrooms. Rarely did the studies explore social presence as practiced by pre-service teachers in the context of synchronous videoconferencing class. Furthermore, there has also been limited research connecting social presence with humanized classrooms.
