Starting school is taking place at an increasingly younger age and can create a range of potentially stressful demands on young children, their parents and teachers. This paper explores some of the situations and changes with which children are faced during their transition to school. These include aspects such as change of status, familiarisation with a new environment, new social experiences and different cultural influences. The issues, therefore, are how children cope with changes and how might they be helped to gain some strategies for dealing with these changes. It looks at the perceptions of 50 children, their parents and teachers in two different schools and highlights the importance of communication and friendships as children start their journey through school. L'école qui commence a lieu à un de plus en plus plus jeune âge et peut créer une portée de potentiellement demandes de stressful sur les jeunes enfants, leurs parents et leurs enseignants. Ce papier explore une partie des situations et les changements avec quels enfants sont fait face à pendant leur transition à l'école. Ceux-ci incluent des aspects tel que le changement de statut, familiarisation avec un nouvel environnement, les nouvelles expériences sociales et les influences culturelles différentes. Les questions, sont donc comment des enfants font face à des changements et pourraient comment ils est a aidé à gagner quelques stratégies pour traiter ces changements. Il regarde les perceptions de 50 enfants, leurs parents et leurs enseignants dans deux écoles différentes et souligne l'importance de communication et les amitiés comme les enfants commencent leur voyage par l'école.  相似文献

As hill jumps are very time-consuming, ski jumping athletes often perform various imitation jumps during training. The performed jumps should be similar to hill jumps, but a direct comparison of the kinetic and kinematic parameters has not been performed yet. Therefore, this study aimed to correlate 11 common parameters during hill jumps (Oberstdorf Germany), squat jumps (wearing indoor shoes), and various imitation jumps (rolling 4°, rolling flat, static; jumping equipment or indoor shoes) on a custom-built instrumented vehicle with a catch by the coach. During the performed jumps, force and video data of the take-off of 10 athletes were measured. The imitation and squat jumps were then ranked. The main difference between the hill jumps and the imitation and squat jumps is the higher maximal force loading rate during the hill jumps. Imitation jumps performed on a rolling platform, on flat ground were the most similar to hill jumps in terms of the force–time, and leg joint kinematic properties. Thus, non-hill jumps with a technical focus should be performed from a rolling platform with a flat inrun with normal indoor shoes or jumping equipment, and high normal force loading rates should be the main focus of imitation training.  相似文献

New teachers have a structured induction programme when they first begin teaching and there are systems in place for new headteachers, but for those teachers who are moving to a new post there is often little support. This article looks at mid-career induction. It explores the formal and informal induction acculturation processes that operate and a model of mentoring new staff in a behaviour support unit where staff are working with several agencies. It identifies that opportunities for development to facilitate growth within a learning organisation can occur when the potential of newcomers is recognised.  相似文献

Structural variation of the human genome sequence is the insertion, deletion, or rearrangement of stretches of DNA sequence sized from around 1,000 to millions of base pairs. Over the past few years, structural variation has been shown to be far more common in human genomes than previously thought. Very little is currently known about the effects of structural variation on normal child development, but such effects could be of considerable significance. This review provides an overview of the phenomenon of structural variation in the human genome sequence, describing the novel genomics technologies that are revolutionizing the way structural variation is studied and giving examples of genomic structural variations that affect child development.  相似文献

The ubiquity of mobile devices together with its potential to bridge classroom learning to real-world has added a new angle to contextualising mathematics learning. This study investigated the effects of using mobile technologies to students’ attitudes and achievement. A quasi-experimental mixed method design was adopted. Participants were 52 Primary 6 and 7 students. The experimental group participated in a weekly mobile-supported, collaborative learning activities spanning over three months. A no treatment control group was adopted. The experimental group have positive perception of the activities evidenced by student interviews and end activity evaluations. Students’ attitude to mathematics, as assessed by a mathematics attitude inventory, found no significant change for both groups except for the significant decline in enjoyment for the control group. A t test of the gain score between group showed a significant difference, t(43) = 4.57, p = 0.005, ES = 0.89 which indicates that the experimental group had higher gains than the control group. These results indicate that the use of mobile technologies elicit positive responses from students both in terms of how they perceive the mobile activities and how it improved their performance but its’ effect on students attitudes towards mathematics will need to be further investigated. Some implications of the findings are discussed.  相似文献

University students often report high stress levels, and studies even suggest a recent increase. However, there is a lack of theoretically based research on the structural conditions that influence students’ perceived stress. The current study compared the effects of Karasek’s demand–control dimensions with the influence of neuroticism to address environmental and individual characteristics related to stress. Two points of measurement were included: T1 in the middle of the term and T2 during the examination period. Participants were 146 psychology students at two German universities (Mage = 22.6 years). We applied an adapted version of Karasek’s Job Content Questionnaire, a self-developed stress scale, and the 21-item Big-Five-Inventory. At T1, both neuroticism and demands significantly predicted stress (total adjusted  = .40), although relative weights analyses indicated that the contribution of demands was more pronounced (relative importance: 63%). Longitudinally, controlling for stress at T1, the demand–control dimensions explained additional variance in the increased stress level at T2, whereas neuroticism did not contribute additionally ( = .52). Results indicate that self-reports on stress among university students are not only a reflection of underlying negative affectivity. We conclude that perceived stress can be explained by structural conditions rather than personality, providing opportunities to reduce stress among students.  相似文献
