Accumulating evidence suggests children enrolled in full-time child care often display afternoon elevations of the hormone cortisol, which is an indicator of stress. Recent advances in immunoassays allow for measurement of activity in the hypothalamic–pituitary–adrenal axis and the autonomic sympathetic nervous system from saliva, and measurement of both systems provides a more complete understanding of activity in the stress response system. This study is the first to examine both cortisol and alpha-amylase in children attending child care and focuses on the influences of specific indicators of classroom process quality. A diverse sample of 63 preschool children nested in 14 classrooms of varying quality participated in this study; child salivary cortisol and alpha-amylase were collected at six times over 2 days. Results indicate that children in classrooms with higher Emotional Support displayed a greater decline in cortisol from morning to afternoon. Further, children in classrooms with higher Emotional Support exhibited lower total alpha-amylase output while attending child care. Implications for professional development for early childhood teachers and measurement of classroom quality are discussed.  相似文献

The Feeling of Thinking in Professional Self‐study   总被引:1,自引:0,他引:1  
Studying one's own professional work is no straightforward matter and adopting the reflective mode is not simply a cerebral activity. As we study our teaching, we are studying the images we hold of ourselves as teachers. Where these established self‐images are challenged, questioned and perhaps threatened in the learning process we may experience feelings of instability, anxiety, negativity, even depression. This is especially so if the ‘self we come to see in self‐study is not the “self we think we are, or the ‘self we would like to be. Thinking about our work In self‐evaluation can thus be a highly charged emotional experience, one from which we may be tempted to retreat, thus endangering further learning. If, on the other hand, we have the support of caring, sensitive and interested critical friends to help us through these potentially dangerous processes of self‐evaluation, we are more likely to remain open to further learning and professional development. The company we keep and the circumstances under which we enter into self‐study may have a significant effect, for better or worse, on our professional learning. These issues are illustrated by the experience of two award‐seeking teacher action researchers who used video in their classrooms to aid their self‐study. The paper argues for greater attention to be given to the nature of the learning climate in which self‐study, self‐evaluation and developmental self‐appraisal take place. If the learning climate is not ‘right’, self‐study may become self‐defeating.  相似文献

Curriculum documents for mathematics emphasise the importance of promoting depth of knowledge rather than shallow coverage of the curriculum. In this paper, we report on a study that explored the analysis of junior secondary mathematics textbooks to assess their potential to assist in teaching and learning aimed at building and applying deep mathematical knowledge. The method of analysis involved the establishment of a set of specific curriculum goals and associated indicators, based on research into the teaching and learning of a particular field within the mathematics curriculum, namely proportion and proportional reasoning. Topic selection was due to its pervasive nature throughout the school mathematics curriculum at this level. As a result of this study, it was found that the five textbook series examined provided limited support for the development of multiplicative structures required for proportional reasoning, and hence would not serve well the development of deep learning of mathematics. The study demonstrated a method that could be applied to the analysis of junior secondary mathematics in many parts of the world.  相似文献

Gender differences in young highly able children's psychosocial development were investigated using child and teacher ratings of prosocial behavior and peer acceptance. Developmental patterns were addressed by studying two groups – children in the primary grades (1 and 2) and children in grades 3 to 7. No gender differences were found on teacher or child ratings in the younger group. In the older group, gender differences favoring girls were found on teacher ratings of prosocial behavior and peer acceptance. Comparisons of child and teacher ratings by gender showed that the older boys viewed themselves as demonstrating more social skills and as being more accepted by peers than their teachers did. Implications for education and counselling are discussed.  相似文献

The drying shrinkage accumulation from exposure of freshly prepared gesso layers to relative humidity (RH) cycles was determined to elucidate the mechanism of craquelure pattern formation on panel paintings. The progresive drying shrinkage of the gesso is observed only under the cycles going to high RH levels which bring about transitions from brittle to ductile state of the material. The first incidence of fracture on the gesso layers occurred after a limited number of cycles ranging between a few and 100 for a range of layer thickness between 0.5 and 1?mm. The craquelure patterns stabilised also after a limited number of cycles (30 for the 1-mm thick layer). Upon increase in the gesso layer thickness, the strength of the layer is reduced and the spacing of shrinkage fractures increases. The study demonstrated that craquelure patterns, mimicking historical ones, can be realistically produced in laboratory conditions. Such studies would provide useful information for preparing specimens simulating historic panel paintings and would inform the current efforts on automatic, computer-aided classifications of crack formations on paintings.  相似文献

This paper presents the results of a light levels survey conducted at the Donald W. Reynolds Center for American Art and Portraiture in Washington DC. The museum space is shared by the National Portrait Gallery and the Smithsonian American Art Museum. After six years of extensive renovations, the building reopened to the public in July 1, 2006. The structure was not originally designed to house a museum collection since it contains numerous openings such as windows, doors and skylights, which provide a path for natural radiation to enter the building and come in contact with the artworks. From a preventive conservation standpoint, this is an important problem since sensitive works of art in the collection may be subjected to damage caused by light exposure. Environmental data loggers installed throughout the museum were programmed to take successive measurements every 10 min for 24 h a day, 7 days a week and 52 weeks a year. This light levels assessment started in November 1, 2007 and finished in October 31, 2008. This study presents a new method for determining natural radiation exposures registered in exhibition spaces that rely on both electric lighting and natural lighting, considering the growing trend of using daylight illumination in museums.  相似文献
