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…

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…

In video lectures, instructors naturally produce nonverbal behaviors, such as gestures, facial expressions, and gaze guidance. Instructors' pointing gestures can act as attentional cues, directing students' attention, while their positive facial expressions can act as social cues, eliciting students' positive social response. The current study…

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…

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…

Instructional videos for teaching second language (L2) vocabulary often feature an instructor onscreen. The instructor in the video may involuntarily produce beat gestures with their hands, as occurs in real teaching settings.

In teacher-fronted kindergarten classrooms, questions are an efficient strategy to attract students' attention and guide them through a lesson. However, few studies have examined the related issues by taking co-speech hand gestures into consideration. By annotating and analyzing a videotaped lesson in a Chinese public kindergarten, the present…

Background: Video lectures which include the teachers' presence have become increasingly common. As teacher enthusiasm is a nonverbal cue in video lectures, more and more studies are focusing on this topic. However, little research has been carried out on the interactions between teacher enthusiasm and prior knowledge when learning from video…

This study investigated whether video lectures instructed by a heightened level of expressiveness instructor were better than those instructed by a conventional level of expressiveness instructor or audio-only in promoting students' online learning, and what kind of effects do instructor's facial expressions have on students' learning. Three…

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…

This paper intends to investigate the effectiveness of a new course pattern--TED-motivated English Public Speaking Course in EFL teaching in China. This class framework adopts TED videos as the learning materials to stimulate students to be a better speaker. Meanwhile, it aims to examine to what extent the five aspects of language skills are…

Daily activities of forty-eight 8- to 15-month-olds and their interlocutors were observed to test for the presence and frequency of triadic joint actions and deictic gestures across three different cultures: Yucatec-Mayans (Mexico), Dutch (Netherlands), and Shanghai-Chinese (China). The amount of joint action and deictic gestures to which infants…

This qualitative case study investigates Chinese university English in the context of foreign language (EFL) learners' attitudes about video-aided instruction (VAI), video recording instruction, and mobile phone instruction (learning technologies). When I was working as an English teacher in Mainland China, several instructors and students stated…
