COVID-19 greatly increased the online delivery of higher education. But one limitation of online learning is that students often struggle to stay engaged while watching online lectures. We examined whether including an instructor's face in lecture videos (instructor visibility) enhances student engagement or learning. In two preregistered…

Background: Many instructors transitioned their courses from face-to-face environments to computer-mediated learning environments (CMLEs) following the onset of the coronavirus disease 2019 (COVID-19) pandemic. However, little was known about how teleconferencing platforms and their corresponding functions affect student learning when the COVID-19…

With the increase in life expectancy and the rapid advancement of digital technology, older adults often face challenges where formal learning opportunities are scarce. Consequently, they are compelled to rely on instructional videos for continuous learning. However, many older adults struggle with low self-efficacy and motivation. Although…

This study tested whether seeing others' typed messages while viewing video lectures affected learners' attention and learning performance. Participants viewed one of three versions of a video lecture: (a) conventional video lecture as control; (b) video lecture with others' programmed messages appearing onscreen when the instructor was giving…

Use of online video lectures is increasingly common. However, students may struggle to self-regulate their attention and passively process the content. This study examined whether, and for whom, different types of embedded learning prompts improve student learning from video lectures. Undergraduate physics students (N = 253) watched an online,…

Background: Little is known about the effectiveness of instructors when presenting content in videos alone. In recent years, researchers have increasingly begun to explore the effects of instructors' social cues (e.g., eye gaze, body orientation, etc.) on learning. However, previous studies exploring the effects of eye gaze have confounded the…

On-line learning has been adopted as a major educational technique and method due to the COVID-19 pandemic. Even though COVID-19 led to many problems such as faculty's burden and stress during the early stage of COVID-19, both students and faculties have gradually become familiar with on-line educational environment. The high technology…

Lecture capture (LC) has been implemented globally to enhance accessible resources supporting academic success. Little is known about the effects of teaching students how to effectively use LC to augment learning. This correlational pilot study used a 14-item Likert-like survey to examine relationships between undergraduate LC viewing practices…

The research aims to investigate the influence of integrating innovative teaching technologies on the effectiveness of the educational process and student motivation. This article employed a quantitative research design utilizing a questionnaire. The total number of participants in the study was 150 students. Participants were divided into…

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…

In an online asynchronous vector calculus course, we observed exam answers solved with a formula from online homework instead of the formula from lecture. Our exploratory study investigated (1) why students learned from homework instead of lecture for this topic and (2) their epistemological frames (e-frames) for lecture and homework. Per (1),…

A review of related research found the use of recorded lecture videos (RLVs) in undergraduate mathematics to be negatively correlated with academic performance. To investigate this correlation, an initial study found students' regular RLV use to be linked to surface approaches to learning. The present study continued this investigation and was…

Explaining after pauses in a video lecture can be an effective learning activity, yet students need support to generate comprehensive explanations. This study tested whether providing students access to the visualizations from the video enhances explanation comprehensiveness and transfer performance. Undergraduates (n = 112) watched a 5-part…

Lecture capture videos were explored as beyond the classroom course materials in upper-level descriptive inorganic chemistry courses during Fall 2017, Fall 2018, and Fall 2020 semesters. Page views data from the learning management system (LMS) Canvas site served as a proxy for course content usage materials such as lecture capture videos. There…

Instructor behaviour is known to affect learning performance, but it is unclear which specific instructor behaviours can optimize learning. We used eye-tracking technology and questionnaires to test whether the instructor's gaze guidance affected learners' visual attention, social presence, and learning performance, using four video lectures:…
