To promote the construction of public physical education online courses in colleges and universities and the evaluation of the effectiveness of course teaching, this article combines 3D reconstruction techniques in computer vision to construct a set of human body shape reconstruction models and apply them to physical training exercises and…

Several observation protocols in different theoretical frameworks and components have been designed and validated by teacher trainers and professional development providers to capture and categorize observational data on the characteristics and level of inquiry in science practices. However, certain constraints limit their wide use, such as the…

Giving feedback to student writing is one of the writing teacher's most important tasks in the classroom. Writing teachers can use many forms of feedback, such as written feedback, teacher-student conferencing, peer feedback, or self-assessment. Additionally, the influx of technologies into writing classrooms allows teachers to use screencast…

Amidst the disruptions caused by COVID-19, maintaining learner engagement in traditional and online courses has become a significant concern. This study explores the use of embedded video questions in an undergraduate Biology course grounded in the Learning Experience Design (LXD) pedagogical paradigm with the objective to reduce cognitive load…

This paper demonstrates the value of an innovative test preparation strategy, applied over multiple semesters to one principles of macroeconomics class. The professor makes a video of himself taking a copy of the test students are preparing for, talking aloud about how to think about the question and work through the solution. A natural experiment…

This study investigated students' meaning-making of polymeric concepts during modelling and discuss students' creation of visible representations in chemistry. The analysis combines a phenomenographic and social semiotic approach and leads to the finding and description of 21 different meaning-making processes. We refer to meaning-making as the…

Video is a widely used medium in teacher training for situating student teachers in classroom scenarios. Although the emerging technology of virtual reality (VR) provides similar, and arguably more powerful, capabilities for immersing teachers in lifelike situations, its benefits and risks relative to video formats have received little attention…

The same L2 speaking performance may be analysed and evaluated in very different ways by different teachers or raters. We present a new, technology-assisted research design which opens up to investigation the trajectories of convergence and divergence between raters. We tracked and recorded what different raters noticed when, whilst grading a…

The article shines light upon the differences in the vocabulary demands of academic spoken discourse between three broad scientific disciplines: Life Sciences, Physical Sciences, and Social Sciences. By employing the Academic Word List (AWL) and British National Corpus/Corpus of Contemporary American English (BNC/COCA) wordlist, the present study…

When the COVID-19 pandemic moved teaching and learning to remote and virtual spaces, teacher professional learning moved online as well. To create consistently high-quality teacher learning opportunities, many online asynchronous approaches need improvement, and they need to be tailor-made for the online setting. That was the authors' goal when…

Purpose: Children with developmental language disorder (DLD) have well-documented verb learning difficulties. In this study, we asked whether the inclusion of retrieval practice during the learning period would facilitate these children's verb learning relative to a similar procedure that provided no retrieval opportunities. Method: Eleven…

Researchers in physics education have advocated both for including modeling in science classrooms as well as promoting student engagement with sensemaking. These two processes facilitate the generation of new knowledge by connecting to one's existing ideas. Despite being two distinct processes, modeling is often described as sensemaking of the…

Driven by the digital revolution in second language (L2) classrooms and broadened views on literacy, digital multimodal composing (DMC) has gained a robust growth of interests in the past decade. To illuminate the empirical landscape of this budding field, this paper provides a substantive and methodological review of 60 empirical L2 studies on…

This article introduces a video-based pedagogical action research model for primary and secondary teachers. The video-based pedagogical action research model incorporates video as a self-reflective tool to provide opportunities for teachers to utilize concrete artifacts in each phase of the pedagogical action research process. Sixty-seven…

We compared maternal speech in interactions of mothers with their firstborn dizygotic twin and singleton infants. Nine twins and nine singletons were video-recorded at home in spontaneous face-to-face interactions with their mothers, from the 2nd to the 6th month. Continuous micro-analysis revealed that there are more quantitative and qualitative…
