A faster running speed is associated with a greater body weight loss in 100-km ultra-marathoners

In 219 recreational male runners, we investigated changes in body mass, total body water, haematocrit, plasma sodium concentration ([Na(+)]), and urine specific gravity as well as fluid intake during a 100-km ultra-marathon. The athletes lost 1.9 kg (s = 1.4) of body mass, equal to 2.5% (s = 1.8) of body mass (P < 0.001), 0.7 kg (s = 1.0) of predicted skeletal muscle mass (P < 0.001), 0.2 kg (s = 1.3) of predicted fat mass (P < 0.05), and 0.9 L (s = 1.6) of predicted total body water (P < 0.001). Haematocrit decreased (P < 0.001), urine specific gravity (P < 0.001), plasma volume (P < 0.05), and plasma [Na(+)] (P < 0.05) all increased. Change in body mass was related to running speed (r = -0.16, P < 0.05), change in plasma volume was associated with change in plasma [Na(+)] (r = -0.28, P < 0.0001), and change in body mass was related to both change in plasma [Na(+)] (r = -0.36) and change in plasma volume (r = 0.31) (P < 0.0001). The athletes consumed 0.65 L (s = 0.27) fluid per hour. Fluid intake was related to both running speed (r = 0.42, P < 0.0001) and change in body mass (r = 0.23, P = 0.0006), but not post-race plasma [Na(+)] or change in plasma [Na(+)] (P > 0.05). In conclusion, faster runners lost more body mass, runners lost more body mass when they drank less fluid, and faster runners drank more fluid than slower runners.     

Knowledge Orientations of Prospective Early Childhood Teachers: A Study of Students' Scientific Versus Subjective Orientations in Teacher Education Courses in Germany

Recent changes in the system of early childhood teacher education in Germany raise the question of whether different academic levels of early childhood teacher education lead to different beliefs and orientations. In this study, prospective early childhood teachers' orientations to scientific knowledge and to research were explored. A questionnaire addressing orientations to the utility of research, educational and psychological theories versus orientations to intuitive theories and personal experience was completed by 712 prospective early childhood teachers. In a latent profile analysis, two types of orientation profiles could be identified: (a) an orientation towards subjective theories, lay theories, and subjective experience, and (b) an orientation towards scientific theories and research results. Results are discussed from the perspective of professionalization in early childhood teacher education.     

No public value without a valued public

This study aims to enlighten the controversial discussion about the term public value in an innovative way. Instead of normative pronouncements and paternalistic posits, this study combines a theoretical, literature-based conception with an empirical quantitative approach. For this, the key term, public value, is split into its constituent parts of customer value and citizen value and is transformed into measurable attributes. By means of a choice-based conjoint analysis on panel data for Germany and the United Kingdom, we explore which performance attributes of public service broadcasters are the most important. Based on the results, we create a conception of public value from the perspective of the license fee payers as the main stakeholder of public service broadcasters. Our findings may unlock existing potential to increase our understanding of what is meant by the term public value.

Block scheduled versus traditional biology teaching—an educational experiment using the water lily

In this study, we compared a traditional teaching sequence (four distinct lessons) with a block schedule dealing with the ecological adaptations of the water lily. The educational unit contained original plant material and both experimental groups received the same tasks and working sheets. Pupils worked together in groups of three to four pupils in a self-regulated manner, carrying out hands-on experiments. However, both groups differed in their time schedule (four distinct lessons of 45 min versus one block of 180 min). Pupils from the traditionally scheduled education performed significantly better in the immediate post-test while these differences merged in retention.     

No Difference in the Neural Underpinnings of Number and Letter Copying in Children: Bayesian Analysis of Functional Near‐Infrared Spectroscopy Data

It is under debate whether the neural representation of numbers and letters might rely on distinct neural correlates, or on a mostly shared neural network. In the present study, a total of 47 children in fifth grade (Experiment 1) and sixth grade (Experiment 2) simply copied numbers and letters on a touch screen while brain activation changes were recorded by means of functional near‐infrared spectroscopy (fNIRS). fNIRS data of both experiments and a joint analysis revealed that a shared neural network, particularly in the left hemisphere, was activated in response to both number and letter copying. Interestingly, no difference was observed in brain activation patterns between these two stimuli, as revealed by Bayesian analysis. Our findings indicate that both number and letter copying lead to similar brain activation in children. We further suggest methodological and applied applications of these findings in the frame of educational neuroscience.     

The role of elevation in moral judgment

ABSTRACT

Elevation is the emotion elicited by witnessing acts of moral beauty and may be framed as the opposite of disgust. Two studies investigated the role of elevation in moral judgment and its relation to disgust. In Study 1 it was investigated whether elevation can attenuate the effects of disgust on moral transgression judgments. Participants were either induced to experience disgust (by giving them a bitter beverage), or to experience disgust and elevation simultaneously (by video induction). No effects of either emotion on moral transgression judgments were found. In Study 2 the nature of causal connectedness between elevation and moral virtue judgments was investigated by testing whether elevation amplifies moral virtue judgments. It was found that participants judged morally good acts as being more morally good when being elevated, suggesting that there is a bidirectional causal link between elevation and judgments of moral virtue.

The role of schools in explaining individuals’ subject choices at age 14

Abstract

The subjects that young people study from age 14 onwards may have important consequences for their future academic and labour market outcomes. These decisions are shaped by the schools in which they find themselves. Schools also face constraints of their own. This paper explores the extent to which individuals’ decisions are affected by the school they attend and to what extent this is affected by the composition of schools in terms of academic attainment, gender, and socioeconomic background. We use multi-level variance decomposition models applied to administrative data on the subjects that young people in mainstream state-funded schools in England study between ages 14 and 16. Our results highlight the important role that constraints on schools play in subject choice decisions. We also note the particular role of attending a non-selective school within a selective schooling district.     

Student teachers’ appraisal of the importance of assessment in teacher education and self-reports on the development of assessment competence

Abstract

Competence in assessment has been identified as a key feature in teachers’ professional success. However, assessment competence is a complex field, comprising capacity in both summative and formative assessment. Hence, a detailed view on how student teachers perceive assessment is the focus of this study. Based on an official catalogue of assessment standards, over 900 student teachers repeatedly rated the importance of the standards and the frequency with which they behaved in accordance with the standards in practicum situations. Analyses revealed that (a) students perceived assessment competence as a contextual entity distinguishable from other domains, (b) while they assigned high importance ratings to assessment standards in general, standards concerned specifically with external evaluation were seen as relatively unimportant, and (c) they perceived a rise in their own assessment competence during their teacher education. Taken together, this suggests that in the student view assessment competence is important and develops over time.
