The critical power (CP) concept has received renewed attention and excitement in the academic community. The CP concept was originally conceived as a model derived from a series of exhaustive, constant-load, exercise bouts. All-out exercise testing has made quantification of the parameters for the two-component model easier to arrive at, which may…

The current study tested several competing models of the autism phenotype using data from modules 1 and 3 of the ADOS. Participants included individuals with ASDs aged 3-18 years (N = 1,409) from the AGRE database. Confirmatory factor analyses were performed on total samples and subsamples based on age and level of functioning. Three primary…

Action research is defined as using research activities to develop concrete societal practices. Action research understands the change of practice as being already a central aim of the research process itself, and it also seeks to contribute to the professional development of all participants in the particular field of study. Even though (or maybe…

For mixed-type tests composed of dichotomous and polytomous items, polytomous items often yield more information than dichotomous items. To reflect the difference between the two types of items and to improve the precision of ability estimation, an adaptive weighted maximum-a-posteriori (WMAP) estimation is proposed. To evaluate the performance of…

In three experimental tasks Stephen and Mirman (2010) measured gaze steps, the distance in pixels between gaze positions on successive samples from an eyetracker. They argued that the distribution of gaze steps is best fit by the lognormal distribution, and based on this analysis they concluded that interactive cognitive processes underlie eye…

In teaching the science of the nano world, ball-and-stick molecular models are frequently used as 3D representations of molecules. Unlike a chemical formula, a molecular model allows us to visualise the 3D shape of the molecule and the relative positions of its atoms, the bonds between atoms and why a pair of mirror isomers with the same atoms,…

The assumption that bodies have little to do with thinking--other than to be the vehicle that gets a mind to a classroom--deeply underpins the traditional model of schooling. Lessons and seminars are designed on the premise that thinking happens best when people are pretty still, their bodies are quiet and undemanding of attention, and they are…

Introductory textbooks in solid state physics usually present the hydrogenic impurity model to calculate the energy of carriers bound to donors or acceptors in semiconductors. This model treats the pure semiconductor as a homogeneous medium and the impurity is represented as a fixed point charge. This approach is only valid for shallow impurities…

We have two aims here. Our first is to articulate what gains may be made by students who engage in our course to determine what exactly is gained by students who participate in such experiences. We believe such courses have educational value, but needed to find a way to articulate our course's success in helping students meet our stated learning…

University students in Macao are required to attend computer literacy courses to raise their basic skills levels and knowledge as part of their literacy foundation. Still, teachers frequently complain about the weak IT skills of many students, suggesting that most of them may not be benefiting sufficiently from their computer literacy courses.…

Globalisation and rapid technological progress have increased the focus on efficient investment in high-quality skills across the European Union (EU) countries. One issue that is high on the political agenda is the persistent underachievement among youths in many European countries meaning that approximately 20 percent of Europe's 15 year olds…

This proposal reports on the theoretical underpinnings and first findings from a five-year longitudinal study (2013-2018) on networked systems in Switzerland. The aim is to assess which conditions lead to a higher functional quality of cooperation between agents in the education sector as well as to assess the possible impact of networked systems…

Educators of international students are frequently challenged to cope with a clashing diversity of cultures in a classroom setting. This study examined what sorts of themes and images might resonate across nationalities and cultures, which could then be used as transcultural tools for international educators. The study employed mixed qualitative…

This commentary highlights convergent themes from four articles in the March 2009 issue of "Educational Researcher" on measuring classroom instruction. Classroom instruction is a complex enterprise that occurs at the intersection of teachers, students, and texts within the surrounding classroom, school, and community environments. Progress in…

Purpose: The purpose of this paper is to provide an empirical comparison of two measures of school success -- a value-added assessment system and the federally-mandated system of adequate yearly progress (AYP) -- to identify highly effective urban schools in the USA and to explore the predictive relationship between evidence-based decision-making…
