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…

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…

The COVID-19 Pandemic, which has affected the entire world profoundly, has given rise to changes in many areas. The change in the education system appears as a compulsory transition to distance education, which raises the question as to how long the lectures in distance education should last. This study examined the emotional changes of the…

We present a system that automatically generates deictic gestures for animated pedagogical agents (APAs). The system takes audio and text as input, which define what the APA has to say, and generates animated gestures based on a set of rules. The automatically generated gestures point to the exact locations of elements on a whiteboard nearby the…

Lectures prevail as a ubiquitous teaching and learning method across universities worldwide. Whereas lectures have been conceptualized from language-centred perspectives, lectures' materiality as linked to their socio-cultural and historical meanings have been scarcely explored. To address this gap, we tackle the materiality of communication in…

In this article we present a case study concerning a simple but efficient technical and logistic concept for the realization of blended teaching of mathematics and its applications in theoretical mechanics that was conceived, tested and implemented at the Department of Civil, Environmental and Mechanical Engineering (DICAM) of the University of…

The present study aims to explore an embodied approach to students' deep learning; specifically, how deep learning is interactively achieved through teachers' languaging dynamics and multimodal representations in interactive lecturing in L2 higher education (HE) contexts. The purpose is to understand how an instructor's embodied and multimodal…

This study tested 3 instructor presence features in learning from video lectures: dynamic drawings, eye contact with the camera, and instructor visibility. In 2 experiments, college students watched a video lecture about the human kidney, which consisted of a series of drawings and a spoken explanation from the instructor, and then took a written…

Recent research on video lectures has indicated that the instructor's pointing gestures facilitate learning performance. This study examined whether the instructor's pointing gestures were superior to nonhuman cues in enhancing video lectures learning, and second, if there was a positive effect, what the underlying mechanisms of the effect might…

Purpose: The purpose of this work is to present a prototype of the system and the results from a technical evaluation and a study on possible effects of recordings with active camera control on the learner. An increasing number of higher education institutions have adopted the lecture recording technology in the past decade. Even though some…

Starting from an interest in the teachers' use of diagrams and gestures during a traditional front lesson at tertiary level, this research takes a narratologic perspective to see a mathematical lesson as a story, and hence the students' notes as re-tellings of a mathematical story. The first minutes of a traditional mathematics lecture…

Cranial nerve (CN) knowledge is essential for students in health professions. Gestures and body movements (e.g., mime) have been shown to improve cognition and satisfaction with anatomy teaching. The aim of this pilot study was to compare the effectiveness of didactic lecturing with that of miming lecturing for student learning of the CNs. The…

This author discovered that his most powerful tool in the classroom was not to lecture, but to stop speaking at all. The effect of the resulting silence was even more positive than he could have imagined.
