In the literature, one can find many claims about how long a learning video should be, but only a few valid reasons and even less empirical evidence. It is argued that a video should be as short as possible according to the learners' attention span. Short videos shall prevent the learner from becoming too passive. The Segmenting Principle…

Although caregiving responsibilities and need for support persist and evolve across the life course in families with autistic youth or youth with other developmental disabilities (DDs), little is known about support during their child's adulthood years. Therefore, the present study used a mixed-methods approach to examine change and stability in…

Even with the increase in virtual learning, there remains a stigma that virtual schools are not successfully supporting students based on traditionally lower graduate rates and state assessment data. The problem is statewide educational decision-makers lacked an understanding of the prior academic performance, specifically credit attainment, among…

How faculty choose--or feel compelled--to spend time on preparing for and reflecting on their teaching is influenced both by capitalist notions of efficiency and productivity and by human, relationship-focused conceptions of growth. The educational development opportunities that faculty are offered at the intersection of these influences can…

Email has become a prominent communication tool for principals. Although principals have reported benefits of communicating via email, they have also indicated that it has intensified their workload. Specifically, principals have indicated that they receive a large volume of email, which contributes to extending and fragmenting their workdays.…

The present study aimed to test if perceived pubertal timing was related to marijuana and alcohol use through deviant peer affiliation. Additionally, we examined if the deviant peer pathway was moderated by impulsiveness, gender, or both. Data were collected from 342 youth, most of whom had a family history of substance use disorder. Youth…

This study is the first to explore microdevelopment in sociolinguistic evaluative judgments of standard German and Austro-Bavarian dialect by adult second language learners of German by using dense time serial measurements. Intensive longitudinal data (10 observations per participant) were collected from four learners at approximately weekly…

This article examines school history textbooks in Afghanistan and investigates the particular ways in which conceptualizations of temporality, history, and the use of calendars contribute toward the construction of the national narrative. It investigates three generations of history textbooks, published between 1998 and 2021 under the Islamic…

This comment on Gascón & Nicolás (2017) explores relationships between mathematics education research and conceptualizations of time. Using Fabian's critique of temporal perspectives in anthropological research (1983) and Lemke's framework of timescales (2000), we consider ways in which implicit attitudes towards time in research can position…

Despite well-established benefits, the majority of young people around the globe are not sufficiently active. In many countries, including Australia, physical activity (i.e. physical education and school sport) is not mandatory in the final two years of high school (i.e. senior school years). The aim of this study was to assess the impact of a…

Social motivation--the psychobiological predisposition for social orienting, seeking social contact, and maintaining social interaction--manifests in early infancy and is hypothesized to be foundational for social communication development in typical and atypical populations. However, the lack of infant social-motivation measures has hindered…

Screens are becoming omnipresent surfaces inside classrooms, namely through the implementation of personal screens at schools. This implementation reconfigures spatiotemporal organization of lesson activities by introducing specific screen mediated tasks that are majorly conducted individually on screens. By adopting the notion of timescape as an…

Whether high quantities of center-based care cause behavior problems is a controversial question. Studies using covariate adjustment for selection factors have detected relations between center care and behavior problems, but studies with stronger internal validity less often find such evidence. We examined whether within-child changes in hours in…

This qualitative study explores how play informs the making process in a media arts environment. Drawing on Dewey's ([1938]1998). Concepts of experience, purpose, and freedom, we explore how play and making are employed in an out-of-school media arts environment. The purpose of this study is to examine one child's use of digital media in this…

Objective: Determine the temporal and spatial characteristics of stairs versus elevator use in a university residence hall to inform future physical activity promotion efforts. Participants: All residents and visitors for a single, four-story residence hall dormitory building located on a college campus in Orange, CA. Methods: Smart mat systems…
