Background: Research into enhancing the effectiveness of information delivery in asynchronous video lectures remains sparse. This study analyzes the nonverbal teaching behaviours in asynchronous online videos, drawing comparisons between pre-service and in-service teachers (ITs). Objectives: This research primarily aims to juxtapose the nonverbal…

Visual access has long been considered crucial for interpreters, providing essential kinesic cues such as gaze and facial expressions that enhance understanding and emphasis. Despite its acknowledged importance, empirical studies examining the impact of visual access on interpreters' performance remain limited. To date, conclusive evidence…

Incorporating non-verbal data streams is essential to understanding the dynamics of interaction within collaborative learning environments in which a variety of verbal and non-verbal modes of communication intersect. However, the complexity of non-verbal data -- especially gathered in the wild from collaborative learning contexts -- demands…

Background: Learner-generated digital media has gained significant attention as a supplementary learning tool. However, a need exists for empirical research to discern among various learner-generated digital media formats. One potential area of divergence lies in the arousal levels evoked during media creation due to varying emphasis on the…

A video lecture instructor exhibiting positive emotion has been shown to induce similar emotions in students, improving the students' motivation and increasing their attention, thus improving their learning performance. However, little systematic research exists on which specific design features with regards to the instructor can induce such…

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…

Over the last decade, the prevalence of online learning has dramatically increased. As part of their curriculum, students are expected to spend more and more time watching videos. These videos tend to follow a widespread format: a screen recording of slides with a picture-in-picture (PiP) image of the instructor's face. While this format is…

Metacognitive awareness is knowing about learners' own thinking and learning, facilitated by introspection and self-evaluation. Although metacognitive functions are personal, they cannot be explained simply by individual conceptions, especially in a collaborative group learning context. This study considers metacognitive awareness on multiple…

This study tested the interaction effect of the instructor's eye gaze (direct gaze vs. averted gaze) and facial expression (happy face vs. neutral face) on students' attention and learning performance in slide-based video lectures. University students (N = 120) participated in the experiment in a laboratory setting. The results of ANOVAs showed…

Using a descriptive research design, this study explored pre-service teachers' perceptions of synchronous virtual classrooms and Web camera use in online learning. The study sample consisted of 256 pre-service teachers from the education faculty of a university in Turkey, and data was collected using a survey. The results showed that most…

In face-to-face interaction, speakers spontaneously produce manual gestures that can facilitate listeners' comprehension of spoken language. The present study explores the factors affecting the uptake and influence of gesture cues in situations where a speaker is referring to objects visible to the listener. In this context, the listener's…

Purpose. Researchers have recommended using comprehensive visual materials in engineering courses, as visuals instill more information in students than auditory information and they have the ability to engage students more effectively than other types of content and to convey the nuances of non-verbal communication. The purpose of this study was…

This study tested the mutual effects of the instructor's eye gaze and facial expression on students' eye movements (i.e. first fixation time to the slides, percentage dwell time on the slides, and percentage dwell time on the instructor), parasocial interaction, and learning performance in pre-recorded video lectures. Students (N = 118…

The purpose of this research is to show how wearable eye-tracking technology can be employed to assess and enhance classroom management skills by analyzing the instructors' eye movements in a university. The research also aimed to evaluate the instructors' gestures by recording with a video camera synchronized with the eye-tracking data. The…

This study examined the effects of watching gestures and lip movement on second language (English) listening comprehension. The participants were 30 high and 22 low proficient learners of English. There were six listening tasks combining two variables: modality and difficulty. The modality consisted of three types of assessments: Body (the upper…
