Video instruction has been widely studied and is generally considered as effective as live instruction for teaching scientific concepts and procedures. However, there is limited research on the effectiveness of prerecorded videos for teaching more challenging content. This study conducted a controlled experiment on over 300 high school students to…

To investigate how bullying victimization affects academic performance and the mediating effects of social anxiety and short video addiction among adolescents, a questionnaire survey was conducted on 2055 secondary school students in China. A Structural Equation Model was employed to analyze the data. The results showed that bullying…

This article provides robust empirical evidence for the association between science teachers' pedagogical content knowledge (PCK) and student achievement. Unlike previous studies, we employed two approaches (text-based vs. video-based tests) to assess if, and to what extent, teachers' PCK assessed by these two approaches are related to student…

Background: As adequate support, virtual reality (VR) has been increasingly introduced into the classroom to help students learn a new language. However, empirical studies exploring the educational potential of using 360° spherical video-based virtual reality (SVVR) in high-school Chinese language classrooms are still lacking. Objectives: A mind…

Immersive virtual reality (IVR) technology influences students' cognitive processes and affective experience, according to previous research findings. Yet, empirical studies that investigate the impact of IVR on science education in secondary schools are limited. This article reports a pilot study that has two objectives: First, to investigate…

Background Study: The effects of the flipped classroom (FC) on students' academic performance remain ambiguous, and the use of pre-class videos may be one of the main factors hindering students' progress. A software package called GeoGebra has been proposed as a substitute for pre-class videos to aid students' learning. Objective: This study…

"Live streaming comprehensive sexuality education (CSE) to rural schools in China's western region" is an innovative program that was implemented by the United Nations Population Fund (UNFPA), Marie Stopes International of China (MSIC), and the Chinese Family Planning Association (CFPA) between September and December 2020. An 8-week CSE…

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…

This study aimed to examine incidental learning of multiword expressions (MWEs) from bilingual captioned videos among language minority students. The participants consisted of 403 language minority university students enrolled in the Preparatory Year Programme (PYP) in the Southern part of China. The study evaluated participants' vocabulary…

Video observation and content analysis are used to make a "quantitative-qualitative" analysis of English teachers' teaching behavior reflected in English classroom teaching videos, and to accurately describe, analyze, and summarize the characteristics of English teachers' teaching behavior from various aspects. Based on this, this study…

Research on first language (L1) attrition typically focuses on immigrant populations in their second language (L2) environment, yet we know comparably little about L1 attrition in the L1 setting. This study used two lexical tasks to test L1 attrition, a time-sensitive word decision task and a video retelling. Chinese teachers of English vs.…

In tracing two Chinese rural middle school classes for 3 years, this study found the positive impact of adopting the algorithm-based mobile short video platform Douyin on rural adolescents' intrinsic motivation. The application's broad adoption has reshaped the social processes supporting adolescent users' intrinsic motivation and spontaneous…

Although the chemical literature contains many studies of multimedia-based learning and teacher enthusiasm, there is a paucity of research on whether and to what extent teacher enthusiasm in video lectures affects students' learning, especially in chemistry. In this context, this mixed-method study used eye tracking and quantitative analysis to…

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…

The effectiveness of demonstration-based training (DBT) videos for software training has been investigated for a Western audience. These studies have generally found that the demonstration videos significantly enhanced self-efficacy and task performance, but also that there was a gap between task practice and learning with the latter lagging…
