Competence to work in schools is an important dimension of professional competence, although it is often a neglected dimension of teacher development. This article reports a qualitative study that examined student teachers’ learning experiences in initial teacher education (ITE) in relation to competence to work in schools. In-depth interviews were conducted with 12 student teachers on an undergraduate ITE programme in Hong Kong. The findings of the study show that competence to work in schools is characterised by student teachers’ deep contextualised learning. In addition, it offers a deeper understanding of this competence in the ITE context by identifying its three facets, namely understanding of the micro-political realities of schools, social capital building and social strategies. The study provides insights for ITE and schools to support student teachers’ development of their competence to work in schools, including the design of ITE curricula, ITE processes and co-curricular activities in undergraduate studies. Moreover, it suggests the importance of developing schools as growth-fostering and positive micro-political sites for ITE fieldwork and teacher induction.  相似文献

Members of this research team are investigating the use of multipoint desktop video conferencing (MDVC) technology in Singapore to enhance the National Institute of Education's schools practicum partnership model. The project builds on the Singapore ONE ATM island-wide network and the high-speed ADSL line access provided by Singtel Magix. This infrastructure provides state-of-the-art support for the White Pine CU-SeeMe Meeting Point server and client software that enables students on teaching practice to conference with each other and their university-based supervisors. A typical conference involves four of five students at different schools and one staff member at the National Institute of Education in Singapore. These conferences provide opportunities for professional sharing between staff and students without the limits of time and space which are traditional constraints on conventional teaching practice.  相似文献

Research on the facilitative effect of diagrams on solving mathematics problems is both inconsistent and inconclusive. This study investigates the effects of diagrams on 124 Singaporean pupils in three classes: Primary One and three, and Secondary One. Pupils' performance was measured with the use of teacher-written mathematics problems in the form of worksheets. Number of errors made on problems accompanied with and without diagrams were compared. Whether or not pupils benefit from diagrams was estimated by their patterns of errors made in the presence or absence of diagrams. Results both confirm and disconfirm previous findings and shed further light on the use of diagrams in mathematics.  相似文献

To enhance the academic achievements of Yi ethnic minority youths in rural school settings, the authors examined the effect of classmate support and the meditating role of ethnic identity in promoting their academic motivation. Cross-sectional survey data were collected from Yi youths sponsored by a philanthropic organization to attend local schools in Liangshan, rural China (n?=?657; 7–12 years old; 52% boys). Results of structural equation modelling showed that classmate support positively affected ethnic identity-commitment and ethnic identity-exploration, which then had positive impacts on three academic motivation outcomes: intrinsic motivation, extrinsic motivation-external and identified regulation, and extrinsic motivation-introjected regulation. The mediating effects of ethnic identity-exploration and ethnic identity-commitment were statistically significant, except for the pathway from classmate support to extrinsic motivation-introjected regulation via ethnic identity-commitment. The authors found that ethnic identity can be facilitated through building supportive classroom environment for positive academic motivations in Yi youths. Cross-cultural significance of this study is also discussed.  相似文献

The recent nationalDiscipline Review of Teacher Education in Mathematics and Science outlines the lack of confidence of many preservice primary school teachers in teaching science. This study explores the attitudes of 170 primary school teachers in a Perth school district. By means of a simple questionnaire the perceptions and attitudes of these teachers about the following aspects have been examined: (1) background understanding of science; (2) preservice training; (3) interest in teaching science; (4) skill in teaching science; (5) confidence in the plant, animal, matter, energy areas, and (6) time spent teaching science. Besides compiling frequency responses for all teachers on these aspects comparisons have also been made on the basis of: (1) gender; (2) time of graduation, and (3) grade level taught. Specializations: Primary science, teacher attitudes. Specializations: Primary science, science teaching strategies, curriculum implementation, cognitive studies.  相似文献

Vocabulary knowledge was tested in a native (Cantonese-Chinese) and foreign (English) language in 150 twins and 150 singletons aged 6–11 years, matched on age, gender, grade level, nonverbal intelligence, parents’ education, family income, and number of siblings and household members. The singletons clearly outperformed the twins on the native vocabulary, but this “twinning effect” was much less noticeable for the foreign vocabulary. The effect on English vocabulary was further reduced after exposure to English at home was controlled. Given that these participants learned most of their English in school rather than home, the present findings support the notion that the twinning effect is associated with increased competition for family interaction in twins compared with singletons.  相似文献

In this paper, we propose that successful education needs to fulfil three purposes while being cognisant of time and context: (a) learning, (b) lifework and (c) well-being. An education system is successful if it can develop future-ready individuals who will continue to learn beyond graduation, take on future lifework, and thrive in a changing society and environment. The future is context-situated and context-dependent. We have chosen to examine the economic, social and environmental context of Singapore to provide insight on the values, skills and knowledge that are required of future-ready learners according to the three purposes. We have compared the trajectories of other high-income nations with those of Singapore. Traditional teaching and learning practices no longer serve us well in the new realities that emerge. Education practices need to evolve in tandem to meet the demands of the 21st century. The roles that school leaders play include creating teaching and learning environments where these practices can be implemented. In our review of leadership practices and concepts, we have found that it is important for school leaders to question existing assumptions of teaching, learning and leadership practices in order to advance the development of 21st century skills, knowledge, values, and habits in learners.  相似文献

In this paper, thermal mixing characteristics of two miscible fluids in a T-shaped microchannel are investigated theoretically, experimentally, and numerically. Thermal mixing processes in a T-shaped microchannel are divided into two zones, consisting of a T-junction and a mixing channel. An analytical two-dimensional model was first built to describe the heat transfer processes in the mixing channel. In the experiments, de-ionized water was employed as the working fluid. Laser induced fluorescence method was used to measure the fluid temperature field in the microchannel. Different combinations of flow rate ratios were studied to investigate the thermal mixing characteristics in the microchannel. At the T-junction, thermal diffusion is found to be dominant in this area due to the striation in the temperature contours. In the mixing channel, heat transfer processes are found to be controlled by thermal diffusion and convection. Measured temperature profiles at the T-junction and mixing channel are compared with analytical model and numerical simulation, respectively.  相似文献
