The control-value theory of academic emotions has emerged as a useful framework for studying the antecedents and consequences of different emotions in school. This framework focuses on the role of control-related and value-related appraisals as proximal antecedents of emotions. In this study, we take an individual differences approach to examine academic emotions and investigate how trait self-control is related to students’ experience of academic emotions. We posited a model wherein trait self-control predicted academic emotions which in turn predicted engagement and perceived academic achievement. Filipino university students answered relevant questionnaires. Results indicated that self-control positively predicted positive academic emotions (enjoyment, hope, and pride) and negatively predicted negative emotions (anger, anxiety, shame, hopelessness, and boredom). Academic emotions, in turn, had a significant impact on engagement, disaffection, and perceived achievement. Implications for exploring synergies between research on trait self-control and the control-value theory of academic emotions are discussed.  相似文献

Undergraduate students accessing on-line tests in Human Biology in three Western Australian universities were asked to complete an on-line post-test reflective survey about their perceptions of their test performance in light of automated feedback. The survey allowed pre-determined choices and comment text boxes relating to students’ perceptions of their performance, self-identified areas of difficulty and suggested strategies for improving test performance. One-third of students undertaking on-line tests responded to the optional survey, and 60% of respondents thought reflecting on feedback was useful. Students reflecting on formative rather than summative assessment reported a more strategic approach to testing, often using it to assess their knowledge and prepare for future assessment. Their reflections were more internally focused on motivation and preparation compared with those assessed summatively. Respondents were more likely to be female, older, more experienced learners who had scored well in the test. Younger respondents expected higher scores than they achieved and were less likely to reflect, but, when they did, were more likely to select pre-determined reasons for their performance and less likely to suggest strategies for improvement. These results support formal training and scaffolded integration of reflection into on-line assessment feedback, especially for less experienced learners.  相似文献

Research Findings: High-quality caregiver–child interactions constitute the core of high-quality child care for young children. This article describes the background and development of the Caregiver Interaction Profile (CIP) scales to rate 6 key skills of caregivers for interacting with 0- to 4-year-old children in child care centers: sensitive responsiveness, respect for autonomy, structuring and limit setting, verbal communication, developmental stimulation, and fostering positive peer interactions. Each interactive skill is rated on a 7-point scale based on observation of video-recorded caregiver–child interactions. Together, the 6 scale scores constitute an Interaction Profile for individual caregivers that may serve as a starting point for education and training to improve the quality of caregiver–child interactions. This article also presents the results of a 1st study with the CIP scales, in a sample of 145 caregivers from 75 child care groups in 47 child care centers in The Netherlands. Practice or Policy: Results provide promising preliminary evidence supporting the reliability and validity of the CIP scales.  相似文献

In this article we argue for the spatialization of research on educational transfer in the field of comparative education within a theoretical framework that focuses on networks, connections, and flows. We present what we call a "spatial empire of the mind," which is comprised of a set of taken-for-granted "truths" about space and place that have legitimized much research in the social sciences. We critique this spatial empire of the mind and present some of the core ideas associated with the spatial turn. The next part of the article reviews three possible ways that new spatial theorizing has been taken up in educational research. Here we make reference to existing educational studies that engage with new ways of rethinking space and place. The argument that we put forward is that the most promising approach, for research on educational transfer within the field of comparative education, is network spatiality. We argue that there is great value in rethinking space and place not simply as objects of study, but within a theoretical framework that focuses on networks, interconnections, and movements within and between them, as well as their productive capacity to produce and shape knowledge, identities, and human subjectivities.  相似文献

To investigate the effects of child-caregiver ratio on the quality of caregiver-child interaction in child-care centers, 217 caregivers (ages 18-56 years) from 64 child care centers were observed during two structured play episodes: one with a group of three children and one with a group of 5 children. As predicted, a child-caregiver ratio of 3:1 produced a significantly higher quality of caregiver-child interaction than a ratio of 5:1 and particularly for younger children. Significant and meaningful effects were found for both the interactive behaviors of the caregivers and the children's well-being and cooperation. Significant correlations with caregiver-child interaction during lunchtime and throughout the remainder of the morning confirmed the ecological validity of the caregiver-child interactions observed during structured play episodes.  相似文献

Among college students, a correlation exists between trauma exposure and eating disorders. Although disordered eating behaviors are more prevalent than eating disorders, the relationship between different types of trauma exposure and disordered eating is unknown. The current study explored this relationship. One hundred two participants completed questionnaires on disordered eating and trauma exposure. Results showed that (a) sexual abuse was a significant predictor of concerns regarding food and weight gain (< .05) and (b) other form of trauma (e.g., natural disaster) was a significant predictor of difficulties in individuals’ relationship with food (< .05). Clinical implications, especially those related to trauma assessment and disordered eating behaviors, are discussed. The importance of examining the impact of nonsexual trauma is described, and the clinical utility of breaking eating pathology down into specific abnormal attitudes and behaviors is highlighted.  相似文献

A school principal’s workload is recognised as being heavy, with an imbalance between demands and resources. This paper contributes to the development of collective leadership. The principalship constellations of six schools in Sweden were studied with the aim of strengthening the current knowledge about structures and experiences of shared principalship. The empirical basis is qualitative data from interviews with principals and vice-principals. The analytical focus was on how the sharing structures were organised and how the shared principalship was experienced. The results point to a considerable variation in the organisational structures of shared principalship. Despite the type of model, form and constellation, the principals and vice-principals voiced a striking sense of relief in not feeling alone in their duties, as problems and troubles became manageable. An intensified interaction level in the principalship constellation created opportunities to develop competence. Theoretically, this study broadens the invited leadership concept to include horizontal invitations across unit boundaries between principals in different units within the same school. The knowledge contribution of this study is useful in discussing the legal possibilities for shared principalship, which may be especially relevant in times when the Swedish school system is being criticised for not delivering good student outcomes.  相似文献

Carbohydrate (CHO) availability during endurance exercise seems to attenuate exercise-induced perturbations of cellular homeostasis and might consequently diminish the stimulus for training adaptation. Therefore, a negative effect of CHO intake on endurance training efficacy seems plausible. This study aimed to test the influence of carbohydrate intake on the efficacy of an endurance training program on previously untrained healthy adults. A randomized cross-over trial (8-week wash-out period) was conducted in 23 men and women with two 8-week training periods (with vs. without intake of 50g glucose before each training bout). Training intervention consisted of 4x45 min running/walking sessions/week at 70% of heart rate reserve. Exhaustive, ramp-shaped exercise tests with gas exchange measurements were conducted before and after each training period. Outcome measures were maximum oxygen uptake (VO2max) and ventilatory anaerobic threshold (VT). VO2max and VT increased after training regardless of CHO intake (VO2max: Non-CHO 2.6 ± 3.0 ml*min?1*kg?1 p = 0.004; CHO 1.4 ± 2.5 ml*min?1*kg?1 p = 0.049; VT: Non-CHO 4.2 ± 4.2 ml*min?1*kg?1 p < 0.001; CHO 3.0 ± 4.2 ml*min?1*kg?1 p = 0.003). The 95% confidence interval (CI) for the difference between conditions was between +0.1 and +2.1 ml*min?1*kg?1 for VO2max and between ?1.2 and +3.1 for VT. It is concluded that carbohydrate intake could potentially impair the efficacy of an endurance training program.  相似文献

Purpose:The present study aimed to examine the link between physical activity(PA)and life satisfaction in a large international study of adolescents.We also aimed to test whether overweight and underweight perceptions act as mediators and whether age and sex acted as moderators.Methods:For this purpose,we analyzed data from the Health Behavior in School-aged Children study,which comprises 727,865 observations from 44 nations at 4 measurement occasions.Results:Multilevel analyses revealed a positive link between PA and life satisfaction.In addition,underweight and overweight perceptions mediated the effect of PA on life satisfaction.We further found that age and sex acted as moderators.In older adolescents,stronger effects were found in the links between PA and life satisfaction,PA and overweight perception,and both weight perceptions and life satisfaction.In addition,in female adolescents,the link between overweight perception and life satisfaction was stronger.Conversely,the links between PA and both weight perceptions were stronger for boys.Conclusion:The results suggest that weight perception explains part of the relationship between PA and life satisfaction in adolescents and that these effects vary as a function of age and sex.  相似文献

Pollutants and their potential degradation of paintings have been measured for the first time in microclimate frames (mc-frames), which are used to protect paintings. The pollutants that were measured include both inorganic pollutants, which originate mainly from external sources, and organic pollutants from mainly internal sources. Those originating from the outdoors enter rooms and subsequently mc-frames at a rate depending on the ventilation rates (air exchange rates) of the mc-frames. The concentration of gaseous pollutants emitted within the mc-frames will depend on net emission rates of the materials used to make the mc-frames, their design, and their ventilation rates. In the EU PROPAINT project measurements of gaseous air pollutants and climatic conditions were performed at various locations both inside and outside different state-of-the-art mc-frames. Diffusive passive pollution gas samplers were used together with different types of dosimeters. Results show that the dosimeters respond to either the photo-oxidizing conditions or the level of volatile organic acids in the environments both in the museums and within the mc-frames. Two dosimeters, the Early Warning Organic (EWO) made from a synthetic polymer and the Resin Mastic coated Piezo electric Quartz Crystals (RM-PQC) respond to photo-oxidation and showed higher values outside than inside the mc-frames. Two other dosimeters, the Glass Slide Dosimeter (GSD) and the Lead coated Piezo electric Quartz Crystals (L-PQC) respond to volatile organic acids and yielded higher values inside than outside the mc-frames. This study emphasizes the need for further work to determine environmental damage functions for paintings, in particular for the effects of organic acids. Such information is essential for the evaluation of the protective effects of mc-frames for paintings. The use of mc-frames is increasing and it is very important to know that this protective measure does not introduce new risks.  相似文献
