Although scholars have generated much research examining enjoyment of mediated sports, much of it has failed to explore how visual production elements shape viewer response. This study examines the impact of one increasingly common technique, subjective camera, on viewer arousal and enjoyment of game play. Participants viewed multiple plays from a college football game that varied in excitatory potential as well as viewing angle. Game play viewed via subjective camera elicited a greater sense of presence in the mediated environment and elicited more frequent arousal responses compared to traditional sideline perspectives of game play. However, the impact of viewing angle on enjoyment as well as self-reported arousal was dependent upon the exciting or dull nature of game play. Invoking the dynamics of excitation transfer theory, we discuss the potential explanations for this relationship as well as its implications for sports broadcasters.  相似文献

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

Background: It is widely agreed that more needs to be done to improve participation in science, technology, engineering and mathematics (STEM). Despite considerable investment in interventions, it has been difficult to discern their effectiveness and/or impact on participation.

Purpose: This paper discusses findings from a six-week pilot STEM careers intervention that was designed and overseen by a teacher from one London girls’ school. We reflect on the challenges for those attempting such interventions and the problems associated with evaluating them.

Sample: Data were collected from Year 9 students (girls aged 13–14 years) at the school.

Design and methods: Pre- and post-intervention surveys of 68 students, classroom observations of intervention activities, three post-intervention discussion groups (five or six girls per group) and a post-intervention interview with the lead teacher were conducted.

Results: Although the intervention did not significantly change students’ aspirations or views of science, it did appear to have a positive effect on broadening students’ understanding of the range of jobs that science can lead to or be useful for.

Conclusions: Student aspirations may be extremely resistant to change and intervention, but students’ understanding of ‘where science can lead’ may be more amenable to intervention. Implications are discussed, including the need to promote the message that science is useful for careers in and beyond science, at degree and technical levels.  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

Alpha-1-antitrypsin deficiency is a hereditary disease leading to hepatitis and cirrhosis. It is the most common genetic cause of liver disease in children which must inherit the tendency from both parents to develop. It acquires the highest priority in the differential diagnosis in a child with chronic liver disease. In this case report we substantiate the role of serum protein electrophoresis, in diagnosing alpha-1-antitrypsin deficiency.  相似文献
