Preschool teachers and classroom aides: Same context,similar perceptions of children's behaviors?

This study explored the correspondence and differences between school staff perceptions of preschool children's social skills and behavior problems. One hundred preschoolers were assessed by 14 pairs of teachers and classroom aides with the Preschool and Kindergarten Behavior Scales – 2^nd Edition (PKBS‐2 Portuguese version). Indexes of agreement and disagreement were calculated. Risk levels and item analyses of PKBS‐2 scores according to both informants' ratings were compared. A higher level of agreement was obtained for social skills scores than for behavior problems (mean correlation of .62). No statistically significant differences between informants were obtained for the risk levels, and item analyses revealed a similar pattern of behaviors that were most and least rated by both informants. Results indicate that the classroom aides' perspective on preschool assessment represents a reliable input, which justifies that they network with teachers in addressing preschoolers' social‐emotional and behavioral challenges.     

Relative shank to thigh length is associated with different mechanisms of power production during elite male ergometer rowing

The effect of anthropometric differences in shank to thigh length ratio upon timing and magnitude of joint power production during the drive phase of the rowing stroke was investigated in 14 elite male rowers. Rowers were tested on the RowPerfect ergometer which was instrumented at the handle and foot stretcher to measure force generation, and a nine segment inverse dynamics model used to calculate the rower's joint and overall power production. Rowers were divided into two groups according to relative shank thigh ratio. Time to half lumbar power generation was significantly earlier in shorter shank rowers (p = 0.028) compared to longer shank rowers, who showed no lumbar power generation during the same period of the drive phase. Rowers with a relatively shorter shank demonstrated earlier lumbar power generation during the drive phase resulting from restricted rotation of the pelvic segment requiring increased lumbar extension in these rowers. Earlier lumbar power generation and extension did not appear to directly affect performance measures of the short shank group, and so can be attributed to a technical adaptation developed to maximise rowing performance.     

Listening and reflecting: an introduction to the special issue

The topic of listening has been broadly neglected in educational studies. This special issue presents studies on the connections between listening and reflecting in educational contexts.

Depending on the kindness of strangers: current national data initiatives and developmental research

This article provides a brief review of current large-scale, longitudinal data collection initiatives focusing on children. These studies will be available for secondary data analyses in the twenty-first century. In addition to child outcome data, process-oriented information is being collected on child-parent interactions, quality of child care, elementary school teacher reports and classroom observations, accessibility and use of health, educational and social services, parental mental health, family violence, fathering, parental residence patterns, income and income sources, child support, employment patterns, and community characteristics. Several of these studies are randomized trials of the efficacy of early childhood intervention services and housing mobility programs. The usefulness of these efforts for exploring policy-relevant issues (child support enforcement, work requirements for welfare recipients, antipoverty strategies, housing subsidies and relocation, availability of child care, child-care subsidies) are discussed.     

The development of children's knowledge of the times of future events

Four studies with 261 children were conducted to describe 4- through 10-year-olds' ability to differentiate the future distances of events. Distances ranged from later the same day through nearly a year in the future. Judgment methods included pointing to parts of a spatial scale representing future distances and answering open-ended questions. Although 4-year-olds failed to differentiate future distances, 5-year-olds were able to distinguish events that would occur in the coming weeks and months from those that would not occur for many months. However, like young children in earlier studies of memory for time, they confused the near future with the recent past. Children 6 through 8 years of age made more differentiated judgments but collapsed the distances of events more than a few months in the future. By 8 to 10 years of age, children accurately judged distances by using mental representations of the times of events in the annual cycle.     

Leveraging Philanthropy in Higher Education

Looking at potential sources of funding for education reform, Frederic Fransen outlines the dynamics in play as a pragmatist might calculate the worthiness of a cause for his philanthropy. Preeminent is bang for the buck, of course. And though the way to reinvigorate the insatiable blob of higher education isn't readily apparent to Dr. Fransen, still, he writes, if you're a reformer seeking financial help, you'd better come up with something comprehensive and attractive to put before today's results-driven donor.     

Learning design and learning analytics in mobile and ubiquitous learning: A systematic review

Mobile and Ubiquitous Learning (m/u-learning) are finding an increasing adoption in education. They are often distinguished by hybrid learning environments that encompass elements of formal and informal learning, in activities that happen in distributed settings (indoors and outdoors), across physical and virtual spaces. Despite their purported benefits, these environments imply additional complexity in the design, monitoring and evaluation of learning activities. The research literature on learning design (LD) and learning analytics (LA) has started to deal with these issues. This paper presents a systematic literature review of LD and LA, in m/u-learning. Apart from providing an overview of the current research in the field, this review elicits elements of common ground between both communities, as shown by the similar learning contexts and complementary research contributions, and based on the research gaps, proposes to: address m/u-learning beyond higher education settings, reinforce the connection between physical and virtual learning spaces, and more systematically align LD and LA processes.
