Extant literature has demonstrated that children's diurnal stress physiology often looks different on childcare versus home days. Specifically, children experience a rise in cortisol, rather than a decline, over the day while in full-time care. Additionally, temperamental fit within classroom environment may influence both child and teacher…

The body is the very basis of children's self-growth and their understanding of the world. However, children's body experiences of growing up have rarely been studied. This paper uses a hermeneutic phenomenological approach to study the body experience of 35 kindergarten children aged 5-6 from Nanjing, China. We found that children's body…

Early childhood educators have one of the most important roles in society, helping the youngest generation flourish, yet educators earn some of the lowest wages. Given their disparate financial value, educators have unsurprisingly reported high stress. Educators' high stress and low wages may affect their health, workplace turnover, and children's…

This study aims to determine what pre-service teachers know about the path of water through the body, and how they intend to explain this knowledge to five-year-old preschool children. This study aims to see the opportunities young children in preschool can obtain from an explanation of the nature of science related to an everyday life activity. A…

The digestive system (DS) is a fundamental topic in biological science teaching. However, the literature indicates that students have difficulties in learning about it. In the present work, we focus on how early childhood Pre-Service Teachers (PSTs) develop their understanding of the DS regarding the CMP (Components-Mechanisms-Phenomena) framework…

Efficient recognition of geometric shapes is an important aspect of proficiency in geometry. Building theoretically on the cultural-historical approach enriched by the physiology of activity, we investigate theoretical perception in geometry--the ability to recognize conceptual geometric aspects of visual figures. Aiming to understand the…

Background: Self-regulation promotes engagement within the classroom. At a physiological level, a good indicator of the ability of the system to self-regulate is cardiac vagal tone (CVT). Aims: The present study aims to assess children's change over time (1 year) in their parasympathetic regulation (by way of CVT) in response to a social and…

This study examined several early childhood education and care (ECEC) factors and their relation to children's salivary cortisol slope and hair cortisol concentration (HCC). The study is part of the cross-sectional DAGIS study, conducted in 2015-2016, examining 66 preschools and 677 children aged 3-6 years in Finland. Two saliva samples from one…

The human nutrition model is relevant in Biology education. Researchers and policymakers propose the introduction of modelling practices in science education, including the representation of the model. Despite being scarce, previous studies have shown that the guideline given to students conditions their performance when representing their models.…

Learning to write is a complex process involving linguistic, cognitive, and socio-emotional factors. From a developmental perspective, little research has explored the content of young children's writings in terms of specific cognitive skills such as Theory of Mind (TOM). This study explores how young children's writing may foster representations…

An awareness of school-related antecedents of children's physiological stress at the beginning of school helps educators to prevent and mitigate children's stress, the one of the major obstacles to their well-being and academic progress. We aimed to study the effect of reading skills and social competence on first-grade students' salivary cortisol…

The overarm throw is a difficult multi-limb task because the overarm throw requires synchronized dexterity of the entire body. Research has determined that the inability to throw hinders children's participation in physical activities. The dynamic systems theory, which describes the interactions and processes that manipulate development, framed…

This study investigated whether parents and kindergarten children show concurrent and time-lagged physiological synchrony during dyadic interaction. Further, we tested whether parent-child behavioral co-regulation was associated with concurrent and time-lagged synchrony, and whether synchrony varied by the type of interaction task. Participants…

For centuries we have been using food for our well-being and health maintenance. As far back as Hippocrates (known as the father of medicine), food has been a center stone used as the good or suffering of humanity. The Bible references food and fasting, cleansing and revitalization to heal the spirit. Before the scientific discovery of synthetic…

Background: To be successful, students must learn to deal with socially and cognitively demanding tasks. Much remains unknown about the effects of previous classroom experiences and of students' emotional appraisal of a task on their physiological adaptive responses to it. Aims: To investigate how children's physiological response to a social and…
