Frequent reels that have gained immense popularity on platforms like TikTok, Instagram, and YouTube, significantly reduce attention span and impairs academic performance. This study investigates the impact of frequent exposure to short video reels on undergraduate students' attention span and academic performance, assuming that attention span…

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…

Reading a book aloud with an adult, or shared book reading (SBR), is a key aspect of children's early experiences with literacy and one that can vary based on social and cultural factors. Based on a sample of 30 Mexican and Dominican families from the New York metro area, the present study investigated book reading strategies used by parents of…

Teachers must be able to monitor students' behavior and identify valid cues in order to draw conclusions about students' actual engagement in learning activities. Teacher training can support (inexperienced) teachers in developing these skills by using videotaped teaching to highlight which indicators should be considered. However, this supposes…

This paper examines the link between cognitive processes and superior performance in contemporary dance. In the first study, thirty-six participants (professional dancers, nonprofessional dancers, and non-dancers) carried out a task in which they were asked to reproduce a sequence of dance steps while being recorded on a camcorder. Analysis…

Students often search for answers online, and gravitate to short explanation videos, which are abundant online. While they seem useful and can be quite engaging, it is unclear if these videos benefit classroom learning. We hypothesized that when carefully matched to the class instruction, video can be helpful, but that benefits will depend on the…

Network analytics has the potential to examine new behaviour patterns that are often hidden by the complexity of online interactions. One of the varied network analytics approaches and methods, the model of collective attention, takes an ecological system perspective to exploring the dynamic process of participation patterns in online and flexible…

My dissertation examines undergraduates' online learning experiences during the COVID-19 pandemic through three distinct studies. The primary goal of my dissertation is to shed light on crucial aspects of social cognitive learning theories and learning experience design (LXD) applied in distance learning. These studies, using an LXD approach…

Recent advances in eye-tracking technology afford the possibility to collect rich data on attentional focus in a wide variety of settings outside the lab. However, apart from anecdotal reports, it is not clear how to maximize the validity of these data and prevent data loss from tracking failures. Particularly helpful in developing these…

This study aims to explore the validity of measuring joint attention through gaze coordination in computer-supported collaborative learning (CSCL) research. Gaze coordination, aligning visual attention in social contexts, aids comprehension and communication. Many CSCL researchers use gaze coordination to gauge joint attention quantitatively.…

This article explores emerging findings in a sensory ethnography based in a nursery setting where video data has been co-produced with parents, practitioners and 2-year-old children. The project mobilises Froebel's twin concepts of 'unfoldment' and 'self-activity', reinstating the importance of the sensory-motor register as a form of knowledge…

This study adds to the construct of science teacher noticing through an analysis that integrates concepts from pedagogical content knowledge (PCK) frameworks. It examines 929 instances of science teacher noticing made via video annotation tools (VATs) over the course of 38 early-career, secondary science teachers' participation in a two-year…

Historically, learning for young students has occurred in formal, in-person classroom environments, but the distance learning context has opened a myriad of learning modalities. To this end, we aim to better understand how deploying learning experience design (LXD) approach supports or hinders children's engagement while participating in an…

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…

How does viewers' knowledge guide their attention while they watch everyday events, how does it affect their memory, and does it change with age? Older adults have diminished episodic memory for everyday events, but intact semantic knowledge. Indeed, research suggests that older adults may rely on their semantic memory to offset impairments in…
