Early Childhood Education and Care Content for the Social Work Curriculum     

Joy Pastan Greenberg  Robert Herman-Smith  Susan F. Allen  Maryah Stella Fram 《Journal of Teaching in Social Work》2013,33(3):308-324

Social workers are poised to play an important role in early childhood education and care (ECEC) settings; however, they need the knowledge and skills necessary to make a meaningful contribution. This article presents learning activities that infuse ECEC content, centered on the following four areas for social work education: (1) history of the profession, (2) observation of current practice, (3) culturally competent service delivery, and (4) advocacy to enhance social justice. Through this infusion of content, social work educators can better prepare their students for the growing field of ECEC practice and for social work practice more broadly.  相似文献   

The influence of lower limb amputation level on the approach in the amputee long jump     

Nolan L  Lees A 《Journal of sports sciences》2007,25(4):393-401

In this study, we investigated the adjustments to posture, kinematic and temporal characteristics of performance made by lower limb amputees during the last few strides in preparation for long jump take-off. Six male unilateral trans-femoral and seven male unilateral trans-tibial amputees competing in a World Championships final were filmed in the sagittal plane using a 100-Hz digital video camera positioned so that the last three strides to take-off were visible. After digitizing using a nine-segment model, a range of kinematic variables were computed to define technique characteristics. Both the trans-femoral and trans-tibial athletes appeared to achieve their reduction in centre of mass during the flight phase between strides, and did so mainly by extending the flight time by increasing stride length, achieved by a greater flexion of the hip joint of the touch-down leg. The trans-tibial athletes appeared to adopt a technique similar to that previously reported for able-bodied athletes. They lowered their centre of mass most on their second last stride (-1.6% of body height compared with -1.4% on the last stride) and used a flexed knee at take-off on the last stride, but they were less able to control their downward velocity at touch-down (-0.4 m x s(-1)). Both this and their restricted approach speed (8.9 m x s(-1) at touch-down), rather than technique limitations, influenced their jump performance. The trans-femoral athletes lowered their centre of mass most on the last stride (-2.3% of body height compared with -1.6% on the second last stride) and, as they were unable to flex their prosthetic knee sufficiently, achieved this by abducting their prosthetic leg during the support phase, which led to a large downward velocity at touch-down (-0.6 m x s(-1)). This, combined with their slower approach velocity (7.1 m x s(-1) at touch-down), restricted their performance.  相似文献   

The energetics and benefit of an arm swing in submaximal and maximal vertical jump performance     

Lees A  Vanrenterghem J  De Clercq D 《Journal of sports sciences》2006,24(1):51-57

The aims of this study were to investigate the energy build-up and dissipation mechanisms associated with using an arm swing in submaximal and maximal vertical jumping and to establish the energy benefit of this arm swing. Twenty adult males were asked to perform a series of submaximal and maximal vertical jumps while using an arm swing. Force, motion and electromyographic data were recorded during each performance and used to compute a range of kinematic and kinetic variables, including ankle, knee, hip, shoulder and elbow joint powers and work done. It was found that the energy benefit of using an arm swing appears to be closely related to the maximum kinetic energy of the arms during their downswing, and increases as jump height increases. As jump height increases, energy in the arms is built up by a greater range of motion at the shoulder and greater effort of the shoulder and elbow muscles but, as jump height approaches maximum, these sources are supplemented by energy supplied by the trunk due to its earlier extension in the movement. The kinetic energy developed by the arms is used to increase their potential energy at take-off but also to store and return energy from the lower limbs and to "pull" on the rest of the body. These latter two mechanisms become more important as jump height increases with the pull being the more important of the two. We conclude that an arm swing contributes to jump performance in submaximal as well as maximal jumping but the energy generation and dissipation sources change as performance approaches maximum.  相似文献

Transitions,transformations and finding success. A phenomenological analysis of the experiences of a doctoral student in early candidature     

Edwin Creely  Stella Laletas 《高等教育研究与发展》2020,39(3):439-453

ABSTRACT

This article examines and analyses the authentic experiences of a doctoral student, Kate, in the period just prior to Confirmation, an academic milestone in the Australian doctoral education context. The article uses qualitative phenomenological inquiry as the methodology and employs ideas drawn from the writings of hermeneutical phenomenologist, Paul Ricoeur, especially his notions of narrative, self, time, and human agency. These ideas are utilised in order to ‘get inside’ the constructions of self, the strategies of learning and adaptation, and the experiences of being a doctoral candidate within the milieu of an Australian university education faculty. The writers argue that such a close and personal examination of experience and a hermeneutical approach to analysis is important for a deep understanding about how Kate negotiated her way through the hurdles of early candidature and adapted her life and identities towards success. Particular focus is given to Kate’s experiences of transition and change and the formation of her academic identity that emerged out of these experiences, which led to successful negotiation of this early period of candidature. The research findings reported in this article suggest that Kate’s deep reflexivity, enjoyment of her research and sense of her own well-being as a doctoral student are significant for her perseverance through difficult milestones and ultimately her successful completion of her PhD.  相似文献   

Improving pre-laboratory preparation of first year university chemistry students     

Marissa Rollnick  Stella Zwane  Mina Staskun  Sandra Lotz  Gail Green 《International Journal of Science Education》2013,35(10):1053-1071

This study uses an action research approach to investigate how different modes of pre-laboratory preparation contribute towards a fruitful laboratory experience for first year students on an access programme. We considered the experience to be fruitful if the students successfully acquired procedural understanding, communicative competence and were able to apply the conceptual understanding to make the purpose of the labs meaningful. A group of students was observed by participant observers during 1996. Data was gathered during laboratory sessions and from written pre-laboratory work. These data were analysed and changes were instituted in the running and conceptualization of the laboratory in the subsequent year. A group of students was again observed and data collected. Two important factors emerged from the analysis of the data. One finding was the importance of adequate student preparation for the laboratories, regardless of the mode of preparation employed. Another was that the ability to prepare depended on the conceptual and procedural understanding of the laboratory as a whole. Preparedness is also important if conceptual benefit is to be obtained from the practical experience.  相似文献

Challenges and management frameworks of residential schools for students with severe emotional and behavioural difficulties in Hong Kong     

Stella Suk‐ching Chong  Ka‐wai Leung 《British Journal of Special Education》2012,39(1):30-38

This study by Stella Suk‐Ching Chong, an assistant professor, and Ka‐wai Leung, a teaching fellow, both at the Hong Kong Institute of Education, focuses on the perspectives of hostel staff from six residential schools for students with severe emotional and behavioural difficulties. Individual or focus group interviews were conducted to explore the range of challenges perceived by staff and the strategies they employed to address the needs of the students. The software N‐Vivo was used to analyse both qualitative and quantitative data. This study finds that staff met a multiplicity of challenges, of which 67.9% were management‐related rather than student‐related (32.1%). In relation to effective strategies for staff, co‐ordinated and concerted efforts are frequently used between different stakeholders, such as intra‐hostel‐staff‐student collaboration (84%), inter‐hostel‐community collaboration (8.6%), inter‐hostel‐home collaboration (5.1%), and finally inter‐hostel‐school collaboration (2.2). In summing up the findings of various approaches deemed favourable by different residential staff, a residential school management framework is conceptualised and presented in this article. Implications and future research directions are also highlighted.  相似文献
