Sustained attention (SA) is an endogenous form of attention that emerges in infancy and reflects cognitive engagement and processing. SA is critical for learning and has been measured using different methods during screen-based and interactive contexts involving social and nonsocial stimuli. How SA differs by measurement method, context, and…

This study examined the effects of an integrated approach that combines segmentation and self-explanation designs on learner achievement for meaningful video-based learning. This was a pretest-posttest research design with a sample size of 121 participants randomly assigned to one of four different types of video instructions (continuous,…

A very simple and color-observable homemade Raman spectroscope with easy preparation is introduced by simply adding low-cost components (a transmission diffraction grating sheet, a magnifying glass, a paper mask, and a DPSS laser pointer module) to a consumer digital camera. The Raman spectral images and profiles of cyclohexane, carbon…

Video is a medium increasingly used in education. The styles of videos produced for academic purposes have been studied in the literature based mainly on those initially designed by instructors for use in MOOCs. In this work, we define a novel taxonomy of academic video design styles based on the videos produced by students. We have defined 10…

The State University of Iowa held inaugural commencement practices in 1857--a mere eleven years after Iowa became a state. The flagship, now named the University of Iowa (UI), has a long and storied commencement history. Commencements have been cancelled. They have been postponed. They have been displaced. But they have never been virtual…until…

Video annotation (VA), a tool which allows commentaries to be synchronized with video content has recently received significant research attention in education. However, the application contexts of these studies are varied and fragmented. A review was therefore undertaken with the objectives to find out the extent to which the use of VA has been…

YouTube has over 2 billion users who watch YouTube videos regularly. It is one of the social media platforms that has increased its popularity in the last years with its use in educational purposes in various grade levels. The purpose of this study is to investigate the factors that make university students use YouTube for learning and studying.…

To help grow the capacity of their teachers to maximize the growth of their students, Keller (Texas) Independent School District used video to provide personalized professional learning to teachers across the career continuum, from new teachers to veteran teachers looking to improve their practice. Their decision to use video-based professional…

Courses: Public speaking. Objectives: This assignment reduces speech anxiety through the affect-reframing power of gratitude, and enables students to consolidate their gains by experiencing social support from a staff mentor.

The growth of multimedia and increasing archival of this footage by public safety agencies presents as a watershed moment in converting this footage into actionable data that can inform and improve public safety practice. However, despite the considerable volume of archival footage, there remains a profound lack of research leveraging this data.…

The integration of digital technology into various sectors has transformed education globally, yet its adoption in Nigeria remains constrained by a lack of adequately trained personnel. This study addresses this gap by developing a Project-Based Arduino Robot Application (PARA) for teaching Robotics Programming to preservice teachers. A Research…

The empirical evidence concerning the question whether an instructor should be presented on online lecture slides is equivocal and two lines of theoretical reasoning exist. On the one hand, the instructor may distract from the content, thereby hampering learning; on the other hand, the instructor may function as a social cue that triggers a more…

Grouping of people and/or things in school can involve challenging pedagogical problems and is a recurrent issue in research literature. Grouping of pupils sometimes aids learning, but detailed video-based analysis of how teachers (and pupils) group or ungroup (termed '(un)grouping') in classrooms is rare. This multimodal classroom interaction…

On the basis of a substantial, robust, and well-replicated cognitive science research literature, interleaving has been recommended across a range of professional pedagogical works as an evidence-based strategy for mathematics teachers. This report first notes the conflation of interleaving and spacing effects underpinning those recommendations…

The current study was designed to investigate how varied time of day (ToD) could affect the acquisition of basketball game actions from different video formats. First-year physical education students (i.e., novice practitioners) were quasi-randomly assigned to three experimental conditions: continuous video, macro-segmented video, or…
