Background: Science teaching and learning, as discursive practices, occur through the utilization of various semiotic modes. Gestures play a pivotal role as an embodied mode that acts in conjunction with speech in oral communication settings, such as classrooms. Previous research on gestures in chemistry and science education has illuminated how…

The interactional roles of smile and laughter have been widely explored in both institutional settings and mundane talk (e.g. Holt 2016; Potter and Hepburn 2010). However, the role of one specific kind of smile, what we call a 'squeezed-mouth smile' (SMS), remains unexamined. Using CA, this study explores one teacher's use of SMS in response to…

This study incorporates communication accommodation theory to investigate how student perceptions of instructor nonaccommodation influence affective and cognitive classroom outcomes. A series of two-level hierarchical linear models (students nested within instructors) revealed significant, negative associations between specific modes of instructor…

Using multimodal conversation analysis, this study closely examines moments when an instructor's embodied explanations elicit laughter from his students -- which we refer to as laughing moments -- in an English as a second language classroom. Such laughing moments can exhibit students' attention to the teacher's explanation and also illuminate…

The demand for writing skills is becoming increasingly prevalent within the U.S. job market. Yet, the biggest barrier to developing successful writing skills, writing apprehension, has received very little attention from scholars in the past 30 years. The present study sought to identify the influence of instructional communicative behaviors on…

The purpose of this case study was to explore the nature of instructors' gestures as they teach Euclidean transformations in a synchronous online setting, and to investigate how, if at all, the synchronous online setting impacted the instructors' intentionality and usage of gestures. The participants in this case study were two collegiate…

The purpose of this research was to reveal in-class communication practices used in the courses in the teacher preparation programs of the USA depending on classroom observations. Qualitative research method was used in the research. The researcher collected the data through direct participatory and unstructured observation. The researcher made…

Material artifacts play an important role in many learning environments. Such artifacts can include sketches, manipulatives, 3D models, toys and games, or the scrap materials found in makerspaces. Some theorists have argued that material artifacts, even though they do not move or talk, should be considered to have autonomous agency and to interact…

This article responds to a call for applied linguistics and bilingualism research from a spatial repertoires perspective informed by new materialism. It focuses on the ways international faculty members carry out instructional interactions in STEM using English as an additional language. Using video data, the analysis demonstrates how visual…

The purpose of this mixed method embedded design study was to examine the effect of a treatment package consisting of video and reflection, video feedback, and coaching on pre-service teachers' use of nonverbal immediacy behaviors as they delivered lessons to student avatars in mixed reality simulations. Pre-service teachers delivered lessons at…

Faculty who do not speak the language of instruction in their universities as their first language face additional challenges in teaching. This study aimed to investigate a non-native speaker faculty member, Eisuke Saito, who had attempted to manage and overcome language challenges in teaching. Through an autobiographical self-study of teacher…

This paper investigates the use of laughter and smiling to manage (dis)affiliation during two types of disturbances in the interactional unfolding of classrooms: delayed and disaligning responses. The analysis reveals that the sequential position and embodied turn design are integral to understanding the (dis)affiliative work laughter and smiling…

It is widely accepted that students' thinking drives teachers' teaching. There are many ways to probe students' thinking with speech or with gestures; however, the literature remains relatively distinct, not focused on both. Prior studies focus on probing students' thinking with speech (talk moves). Although Alibali and colleagues (e.g., Alibali…

This study explores Thai university students' perceptions of their reluctance in verbal classroom participation especially in situations where English is used as the medium for instruction. It is generally perceived that non-native learners particularly from high context cultures such as Thailand have the tendency to remain silent during…

This study explored the language practices of a small group of international Chinese students in an anglophone Higher Education context where English was the medium of instruction. The context was the first year of an early childhood education course at an Australian university. Building on findings from research in conversation analysis on…
