This meta-analysis explores the impact of positive instructors on learning from instructional videos. Both the contagion theory and the cognitive-affective theory of learning with media suggest that positive instructors can facilitate learning. This review analyzed 37 studies reporting various outcomes, including positive emotion, motivation,…

Videos are pivotal tools in pre-service teacher training. First-person, third-person, and 360-degree perspectives are commonly used types and the optimal type remains undetermined. In our study involving pre-service teachers (PSTs), we evaluated the efficacy of 360-degree videos against the first-person and third-person perspective videos…

Background: Leaderboards are a highly popular gamification component used in student learning to enhance motivation, attentional engagement, and learning performance. However, few studies have examined the effects of individual leaderboard elements on English vocabulary learning through video lectures. Objectives: The present study aimed to…

Instructional videos risk overloading learners' limited working memory resources due to the transient information effect. Learner control is one way to mitigate this concern, but has shown almost zero overall effect and considerable heterogeneity. Consequently, it is essential to identify when learner control is most beneficial. The present study…

With the development of information technology, co-viewing of live video streaming (LVS) has become a popular online learning method. However, existing studies have found inconsistent results regarding the effects of co-viewing, which could be due to the impact of learner-learner interactions. The present study tested the effects of co-viewing LVS…

Previous studies have shown that encouraging students to use self-explanation strategies has proven effective in text-focused learning contexts. However, no study to date has focused on how students' strategy preference moderates the effect of self-explanation strategies on learning from video lectures. The current study investigated how students'…

This study investigated the effects of two types of oral explanations (ie, self-explanation vs. instructional explanation) and drawing activity (no drawing vs. drawing) on video learning outcomes. These outcomes were measured by visual attention to the video (indexed by fixation time on text and diagram areas), explanation quality (indexed by…

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. Beat gestures highlight key information in speech by conveying the rhythm of the language, but do not themselves convey…
