This investigation examined the ability of four adults with moderate intellectual disability to complete multi-component tasks using continuous video modeling. Continuous video modeling, which is a newly researched application of video modeling, presents video in a "looping" format which automatically repeats playing of the video while…

In this paper I propose a method of calculating the time between line captures in a standard complementary metal-oxide-semiconductor (CMOS) webcam using the rolling shutter effect when filming a guitar. The exercise links the concepts of wavelength and frequency, while outlining the basic operation of a CMOS camera through vertical line capture.

This study examined the efficacy of video self modeling (VSM) using feedforward, to teach various goals of a picture exchange communication system (PECS). The participants were two boys with autism and one man with Down syndrome. All three participants were non-verbal with no current functional system of communication; the two children had long…

Instructors frequently utilize breaching experiments in an attempt to "bring sociology to life." However, an uncritical embrace of breaching experiments obscures the complexity of their possible effects on participants and subjects. These experiments have real potential to inflict deleterious consequences on individuals and groups.…

This paper argues for an approach to mobile learning that leverages students' informal digital practices as resources for designing mathematics classrooms activities. We briefly describe two exploratory designs along these lines, one featuring the use of photos taken by students outside class and the other centered on their recording and…

Determining the reach of physical activity (PA) programs is challenging due to inconsistent reporting across studies. The purpose of this study was to document multiple indicators of program reach for a 6-month, Digital Versatile Disc (DVD)-delivered home-based PA program. Radio, newspaper and direct mailing advertisements were tracked to…

Purpose: Studying normal or disordered motor control requires accurate motion tracking of the effectors (e.g., orofacial structures). The cost of electromagnetic, optoelectronic, and ultrasound systems is prohibitive for many laboratories and limits clinical applications. For external movements (lips, jaw), video-based systems may be a viable…

Child maltreatment continues to occur at alarming rates, and while several interventions currently exist for use with parents to minimize the incidence of child maltreatment (Daro & McCurdy, 2007), many can be time consuming for service providers "and" consumers. One program, the Circle of Security (COS), lasts 20 weeks with weekly…

This study, framed within Vygotskyan sociocultural approaches to teacher education, aimed at reconceptualizing the thinking and subsequent recontextualizing of the classroom practice of a participating teacher. An Iranian English as a Foreign Language (EFL) teacher with pseudonym--Sara--was the participant of the study. Sara's conceptions of…

Common arguments for integrating the arts into mathematics courses include the arts fostering student creativity, improving academic achievement, and encouraging transfer between subjects. Research supporting these arguments is limited and carries layered complexities--such as what constitutes creativity and transfer, and whether they can be…

We draw on Engeström's (2011a) formative intervention approach to bring together mentor teachers and university supervisors to construct a tool for structuring observations and mentoring student teachers. Data include videos and transcripts from seven meetings where participants discussed mentoring and viewed video records of teaching practice to…

Computer-automated assessment of students' text responses to short-answer questions represents an important enabling technology for online learning environments. We have investigated the use of machine learning to train computer models capable of automatically classifying short-answer responses and assessed the results. Our investigations are part…

This study focuses on the everyday morning microtransition in childcare centres that involves child-parent separation. This moment involves the contemporary presence of the child, caregiver and parent in the day-care centre. This coexistence is considered extremely relevant and full of important meanings for the interactive patterns they will…

The aim of this study was to describe arm and hand movement in children suspected of having autism spectrum disorder (ASD; age range 29-43 months). A videotaped retrospective review of five children with symptoms of ASD during "Communication Temptation Tasks" was completed at two time points (pre-testing and 6 weeks later). Categories of…

This conversation analytic study describes some specific interactional contexts in which native English-speaking teachers produce "oh" in known-answer question sequences in English language classes. The data for this study come from 10 video-recorded Japanese primary school English language class sessions. The analysis identified three…
