This article is a case study of the relation between urban schooling and university education, using two main sources. Data on the schools attended by history students at Edinburgh University between 1899 and 1933 illustrate the diversity and social ranking of schools in the city. New higher grade schools had a key role in increasing access to university education for both men and women, especially for prospective teachers; the significance of the Education (Scotland) Act of 1918 for Catholic schools, and the continuing importance of small private schools for girls, are also shown. The second source analyses the school origins of successful Edinburgh candidates in civil service examinations between 1896 and 1944, supplemented for other parts of Scotland by the report of the Royal Commission on the Civil Service of 1912. This elite career drew mainly from older schools, and contemporary claims for equality of opportunity in Scotland need to be treated with reserve. 相似文献

The brief note aims to illustrate how historical context has contributed to my writing on modern sports law and principally through two pieces of work – the first relating to the historical, sui generis origins of the legality of combat or fighting sports, which continues to stretch the boundaries of core principles of criminal law, such as reasonable consent to bodily harm, to their utmost; and second, and more generally, the ‘historicalegal’ influences on the development of modern sport in mid-nineteenth-century Britain. Before that is done, it is best to give some account of research methodologies in legal scholarship and principally as they apply to legal history. 相似文献

Despite science learning in settings such as science museums being recognized as important and given increasing attention in science education circles, the investigation of parents’ and their children’s metacognition in such settings is still in its infancy. This is despite an individual’s metacognition being acknowledged as an important influence on their learning within and across contexts. This research investigated parents’ metacognitive procedural and conditional knowledge, a key element of their metacognition, related to (a) what they knew about how they and their children thought and learned, and (b) whether this metacognitive knowledge influenced their interactions with their children during their interaction with a moderately complex simulation in a science museum. Parents reported metacognitive procedural and conditional knowledge regarding their own and their children’s thinking and learning processes. Further, parents were aware that this metacognitive knowledge influenced their interactions with their children, seeing this as appropriate pedagogical action for them within the context of the particular exhibit and its task requirements at the science museum, and for the child involved. These findings have implications for exhibit and activity development within science museum settings. 相似文献

In classical model reference adaptive control (MRAC), the adaptive rates must be tuned to meet multiple competing objectives. Large adaptive rates guarantee rapid convergence of the trajectory tracking error to zero. However, large adaptive rates may also induce saturation of the actuators and excessive overshoots of the closed-loop system’s trajectory tracking error. Conversely, low adaptive rates may produce unsatisfactory trajectory tracking performances. To overcome these limitations, in the classical MRAC framework, the adaptive rates must be tuned through an iterative process. Alternative approaches require to modify the plant’s reference model or the reference command input. This paper presents the first MRAC laws for nonlinear dynamical systems affected by matched and parametric uncertainties that constrain both the closed-loop system’s trajectory tracking error and the control input at all times within user-defined bounds, and enforce a user-defined rate of convergence on the trajectory tracking error. By applying the proposed MRAC laws, the adaptive rates can be set arbitrarily large and both the plant’s reference model and the reference command input can be chosen arbitrarily. The user-defined rate of convergence of the closed-loop plant’s trajectory is enforced by introducing a user-defined auxiliary reference model, which converges to the trajectory tracking error obtained by applying the classical MRAC laws before its transient dynamics has decayed, and steering the trajectory tracking error to the auxiliary reference model at a rate of convergence that is higher than the rate of convergence of the plant’s reference model. The ability of the proposed MRAC laws to prescribe the performance of the closed-loop system’s trajectory tracking error and control input is guaranteed by barrier Lyapunov functions. Numerical simulations illustrate both the applicability of our theoretical results and their effectiveness compared to other techniques such as prescribed performance control, which allows to constrain both the rate of convergence and the maximum overshoot on the trajectory tracking error of uncertain systems. 相似文献

The purpose of this research project was to gain a greater understanding of daily routines of 4–7 year olds regarding physical activity and nutrition practices in typical early learning environments. The settings selected for this observational study included Head Start, primary, and after-school learning environments in a city in the southeast. Specifically, this exploratory study focused on the research question: What are typical daily physical activity and nutrition patterns in community-based early learning settings for young children 4–7 years of age in the United States? Two overarching themes were identified through data analysis: restriction of activity and restriction of physical movement. Results indicated that children in elementary school settings had fewer opportunities for indoor and outdoor physical activity than children in other settings and that children seek to be physically active and will do so when given the opportunity. Increasing time for both structured and unstructured physical activity and play for children ages 4–7 in early learning settings was recommended by the researchers. 相似文献

The number of educators, administrators, and institutions that utilize social networking has increased dramatically. Many have adopted social networking in order to be up-to-date and connected with their students’ learning beyond the boundaries of the classroom. However, this increase in the use of social networking in academia presents many potential issues. In this paper, we address the growing prevalence of social networking in education and some of the issues. Next, we use social role theory to explore some pitfalls for educators using social networking. Finally, we suggest that foundational ethical principles from the field of psychology can provide a basis for developing guiding principles for use of social networking in education. 相似文献

This comparative study explored Chinese family groups' dominant visit motivations in science museums and aquariums in order to understand the perceptions of these audiences, who are an under‐represented cultural demographic in the literature. In this study, 503 Chinese participants—131 in the China Science and Technology Museum, Beijing; 127 in the Beijing Aquarium, Beijing; 136 in Science World British Columbia, Vancouver; and 109 in the Vancouver Aquarium, Vancouver—completed a Family Group Visit Motivation Questionnaire. The results report four dominant visit motivations for these Chinese family groups. Significant differences in a fifth motivation, social interaction, were detected in comparing the Beijing and Vancouver Chinese family samples. Also, Chinese family groups were more likely to perceive science museums to be settings that can satisfy their educational and personal interest needs, compared to aquariums. This study provides insights for science museums and aquarium practitioners to better understand this audience demographic. 相似文献
