Objective, quantitative measures of caregiver-child interaction during play are needed to complement caregiver or examiner ratings for clinical assessment and tracking intervention responses. In this exploratory study, we examined the feasibility of using automated video tracking, Noldus EthoVision XT, to measure 159 2-to-7-year-old autistic…

Purpose: This paper adds to the growing body of research examining the impacts of COVID-19 physical distancing measures on the everyday lives of young people. It draws on theories of "digital intimacies" and "relationship maintenance" to argue that young people's reflections on COVID-19, physical distancing and online…

In this work we describe a teaching proposal to calculate the eccentricity of the Moon's trajectory by applying a geometrical technique. The values of the ratios between the Earth-Moon distance and the diameter of the Moon at apogee and at perigee were calculated from a kinematic model associated with a geometrical technique of image analysis. The…

This paper addresses the subject of the semiosis process in the transactions between teachers and students about the knowledge at stake in science education. We present a conceptualisation of these transactions as a joint action between students and teachers. This conceptualisation enables us to understand the semiosis process as it unfolds during…

Teacher praise is an evidence-based strategy shown to increase appropriate prosocial behavior and decrease disruptive behavior, particularly with elementary school age students. In this article, we provide direction and recommendations for using positive feedback with middle and high school students. A review of the research literature, guidelines…

Grounded in Vygotsky's cultural-historical theory, this paper examines how often teachers are involved in children's imaginative play and discusses their beliefs about their role in supporting children's imaginative play. To investigate this problem, video (65 hours of digital observations) and interview data (two hours and 30 minutes) of 60…

Distance education is expanding in all continents, and the use of video has dominated internet. Synchronous Video Communication (SVC) has not been an option thoroughly investigated and practitioners, who use and design synchronous learning scenarios, are in urgent need of guidance. Distant learners face many barriers, and as a result, they drop…
