The study investigated the effect of an instructor's positive (vs. neutral) emotions in video lectures on student learning using either easy or difficult geography topics (i.e. easy: the Earth within the universe; difficult: understanding time and date calculations of Earth). The results showed that, first, students responded more positively…

This electroencephalography (EEG) study tested the benefits of generative learning and the underlying neural mechanism of these benefits when learning from video lectures. Twenty-six Chinese young adults independently viewed two video lectures in a repeated measures design. Each video lecture was broken into 40 segments, and after each segment,…

Massive open online courses are one of the most prominent trends in higher education in recent years. Instructional videos play a significant role in the massive open online courses platform. This study tested the impact of sending danmaku related to video content versus sending danmaku not related to video content versus not sending danmaku in…

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…

Much effort has been put into the design of video lectures, but little attention has been paid to the social environment in which learning takes place. The present study addressed this gap by assigning Chinese undergraduate and graduate students who had passed the College English Test-4 to learn easy or difficult English vocabulary words in three…

Video lectures are being widely used in online and blended learning classes worldwide, and their learning effectiveness is becoming a focus of many educators and researchers. This study examined the cognitive load and learning effectiveness of video lectures in terms of the type of knowledge being taught (declarative or procedural) and instructor…

Massive Open Online Courses (MOOCs) have become increasingly common in recent years. As the main component of MOOCs, instructional videos play a significant role in students' learning. This study builds on the extant research on multimedia learning by testing the impact of teachers' continuous vs. intermittent presence in procedural knowledge…

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…
