Mental health problems in children represent a significant international health concern, with up to one in five children using mental health services during the course of any given year. Identifying the processes of what prevents social, emotional and behaviour difficulties (SEBD) and promotes healthy development from an early age can make a significant contribution to the promotion of positive mental health in children. This article describes a longitudinal study which sought to identify the risk and promotive factors as young children move from the early to junior years in primary school. Multilevel analysis was used to identify the individual, classroom, school, home and community factors that predict change in SEBD and in prosocial behaviour in the early school years. It also calculated the cumulative effect of the various risk and promotive factors on the pupils’ well-being and mental health. The article presents the windows of vulnerability and opportunity for young children’s healthy development, proposing a trajectory for healthy development in early and middle childhood.  相似文献

As a wide range of values has been reported for the relative energetics of 400-m and 800-m track running events, this study aimed to quantify the respective aerobic and anaerobic energy contributions to these events during track running. Sixteen trained 400-m (11 males, 5 females) and 11 trained 800-m (9 males, 2 females) athletes participated in this study. The participants performed (on separate days) a laboratory graded exercsie test and multiple race time-trials. The relative energy system contribution was calculated by multiple methods based upon measures of race [Vdot]O2, accumulated oxygen deficit (AOD), blood lactate and estimated phosphocreatine degradation (lactate/PCr). The aerobic/anaerobic energy system contribution (AOD method) to the 400-m event was calculated as 41/59% (male) and 45/55% (female). For the 800-m event, an increased aerobic involvement was noted with a 60/40% (male) and 70/30% (female) respective contribution. Significant (P <?0.05) negative correlations were noted between race performance and anaerobic energy system involvement (lactate/PCr) for the male 800-m and female 400-m events (r = ? 0.77 and ??0.87 respectively). These track running data compare well with previous estimates of the relative energy system contributions to the 400-m and 800-m events. Additionally, the relative importance and speed of interaction of the respective metabolic pathways has implications to training for these events.  相似文献

The aim of the present study was to quantify the contributions of the aerobic and anaerobic energy systems to 1500- and 3000-m track running events during all-out time-trials performed individually on a synthetic athletic track. Ten 3000-m (8 males, 2 females) and fourteen 1500-m (10 males, 4 females) trained track athletes volunteered to participate in the study. The athletes performed a graded exercise test in the laboratory and two time-trials over 1500 or 3000?m. The contributions of the energy systems were calculated by measures of race oxygen uptake, accumulated oxygen deficit (AOD), race blood lactate concentration, estimated phosphocreatine degradation and some individual muscle metabolite data. The relative aerobic energy system contribution (based on AOD measures) for the 3000?m was 86% (male) and 94% (female), while for the 1500?m it was 77% (male) and 86% (female). Estimates of anaerobic energy expenditure based on blood lactate concentrations, while not significantly different (P?>?0.05), were generally lower compared with the AOD measures. In conclusion, the results of the present study conform with some recent laboratory-based measures of energy system contributions to these events.  相似文献

This paper examines university teacher educators’ engagement with and in educational research. Survey results collected from eighty-two teacher educators at a leading university in Saudi Arabia pointed to modest levels of research activity and also suggested that these individuals held largely technical views of what research is. Their assessments of their institutional research culture also signalled a perceived gap between the research productivity expected of them and the support they received from their university. The implications of these findings for promoting research activity among university teacher educators, where this is considered desirable, are discussed.  相似文献

The paper reports a study for determining a suitable process for converting traditional surface science courses into case‐based learning ones in two universities in Hong Kong. In this preparative study, a set of baseline data was collected on the current level of students’ conceptual understanding and also students’ perceptions about the traditional courses. The student data (from 38 students) came from examination results, the Study Process Questionnaire, a course‐end survey and a focus group meeting; teachers also kept reflective journals. This set of baseline data revealed factors that both support and inhibit case‐based learning. On the one hand, students demonstrate a motivation to be able to solve practical problems in this field; on the other hand, they show an unwillingness to take up a personal responsibility for learning. This finding strengthens our resolve to take into account students’ expectations and beliefs in the implementation of case‐based teaching and learning.  相似文献

The problem of this research was to determine whether training teachers with the Utah State University Protocol Modules brought about significant changes in teaching performance and related pupil outcomes. Twenty-eight in-service elementary school teachers were randomly assigned to two groups. One group was trained in the classroom management modules (Group A), the other in the self-concept modules (Group B). Before and after treatment, teachers and their pupils in both groups were observed in their own classrooms on performance variables related to both sets of modules. Pupils were also administered two self-concept measures. Since the two sets of modules deal with different teacher behavior, this design permitted each group to serve as control for the other group. Results indicated that Group A teachers had significantly more favorable post-treatment means than Group B teachers on 7 of the 13 classroom management skills. Group B teachers had significantly more favorable post-treatment means on 11 of 12 behaviors covered in the self-concept modules. Pupils in Group A classrooms made significant reductions in both mildly deviant and seriously deviant behavior. No significant changes in pupil self-concept test scores occurred.  相似文献

Students in one school system in grades 5 through 11( 522 boys, 548 girls) responded to an objective examination which incorporated a measure of risk taking. The study was replicated in a second school system (600 boys, 691 girls). In each case the proportion of risk-taking variance associated with variation in grade level was approximately . 10 (significant at the . 05 level), with higher risk in grades 5, 6, and 7 than in grades 8, 9, 10, and 11. Boys took greater risks than girls in both school systems, but the proportion of risk-taking variance explained by sex was low ( approximately . 01) and significant (at the . 05 level) in only one school system. There was no interaction between grade level and sex.  相似文献

The promotion of educational equity and improvement of educational quality in China are contextualised in tenets of Confucianism and policy directives, inspiring educational research and practice. In this paper, we first explore the historical and cultural roots of educational equity and quality through Confucianism and elaborate on the current policy priority that aims to address educational equity and quality. We then present an overview of research on equity and quality in Chinese education. Informed by Confucianism, policy, and research, we pose a framework to structure our investigation and analysis of three illustrative examples, namely the Special Post Teacher Plan, amalgamation of rural schools, and schooling of floating children. Drawing insights from Confucianism, policy, research, and practice, we conclude that the promotion of educational equity through high quality provision of education for disadvantaged groups can help to narrow the gap in educational quality currently existing in China.  相似文献

The focal concern of this article is the investigation of the transfer and sustainability of the reflective process into the work environment. Specifically, the identification of the variables which support or challenge practitioners to continue the ongoing process of reflection in practice contexts is addressed. The article describes a study carried out over a seven-year period with students/graduates from a master's in social work (MSW) professional qualification programme in Ireland. The research involved gathering data on participants’ experiences of reflective teaching and learning while on the course and in the initial years of their work as practitioners. In the early phases of the data collection, participants referred to developing epistemological awareness through the reflective process while on the course. This was in the context of a scaffold for reflection through journal writing and mentored portfolio inquiry. The outcomes of the study offer considerable insight into the challenges and value of developing a reflective teaching and learning environment in professional education. In particular, the work highlights how it impacts positively on professional practice.  相似文献

This paper reviews studies on occupational stress among teachers in British schools carried out over the last 15 years. Four major themes are considered: (1) the prevalence of self‐reported occupational stress; (2) sources of stress; (3) symptoms and effects of stress; and (4) coping actions. The reviewed studies have investigated these themes in various teacher samples ranging from mainstream to special schoolteachers, heads of departments, deputy heads and head teachers. It is argued that, in view of the recent and ongoing changes in schools and their curricula as well as the prevailing working conditions of teachers, our present understanding of stress in teaching needs to be based on updated information. Some recommendations for future research are also set out.  相似文献
