The paper aims to develop training for teachers to perceive non-verbal cues in online classes. The training is prepared based on a mindmap suggesting alternative tools available in the online platforms to gauge non-verbal cues in online lectures. The findings indicate that after the training, teachers could perceive students' non-verbal cues…

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…

Learning from video lectures is becoming a prevalent learning activity in formal and informal settings. However, relatively little research has been carried out on the interactions of learning strategies and social environment in learning from video lectures. The present study addresses this gap by examining whether learner-generated explanations…

In lectures with presentation slides such as an e-learning lecture on video, it is important for lecturers to control their non-verbal behavior involving gaze, gesture, and paralanguage. However, it is not so easy even for well-experienced lecturers to properly use non-verbal behavior in their lecture to promote learners' understanding. This paper…

Instructors' speech and gestures are tightly integrated. However, little is known about the neural mechanisms by which different types of gestures affect learning. We conducted two experiments on the effects of gestures in video lectures that included an instructor and slides, with English vocabulary as the topic. In Experiment 1, we manipulated…

Spatial understanding of complex anatomical concepts is often a challenge for learners, as well as for educators. It is even more challenging for students with low mental spatial abilities. There are many options to teach spatial relationships, ranging from simple models to high-end three-dimensional (3D) virtual reality tools. Using a randomized…

Pre-recorded lectures have become a prevalent approach in online education due to the proliferation of MOOC platforms and the COVID-19 pandemic. However, due to the lack of real-time interactions between instructors and learners, learners have encountered various difficulties in understanding the lectures and actively engaging with the learning…

During the COVID-19 pandemic, video materials have played crucial roles in supporting learning among children with autism spectrum disorder (ASD). This study aimed to explore the effects of the instructor's facial expressions in video lectures on attention and motor learning in children with ASD versus typically developing (TD) children. A total…

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…

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…

Evidence regarding the benefits of an instructor's deictic gestures in video lectures on adults' learning may not necessarily be reflective of their effect on children's learning. Furthermore, there is a lack evidence regarding how deictic gestures specifically affect learners' learning process. Based in cognitive load theory, with consideration…

Online learning has gained increasing attention during the COVID-19 pandemic. Teachers face social exigencies to design ways of knowledge dissemination in online instruction. We posit that understanding how knowledge can be represented in successful online academic genres can inform teachers on how they can design students' online learning…

The positivity principle states that people learn better from instructors who display positive emotions rather than negative emotions. In two experiments, students viewed a short video lecture on a statistics topic in which an instructor stood next to a series of slides as she lectured and then they took either an immediate test (Experiment 1) or…

An instructor's gestures have an effect not only on students' learning but also on teaching itself. In two experiments, this study tested whether instructors' use of gestures while recording video lectures affected their teaching performance, stress, and cognitive load. In Experiment 1, participants recorded video lectures with gestures or without…

As an important resource in online learning, video lectures have attracted considerable research attention in the impact of teachers' nonverbal guidance behaviors on learning. However, few studies have focused on secondary education, and it remains unclear whether the interaction between different guidance frequencies and types leads to variations…
