Should Science be Taught in Early Childhood?     

Haim?EshachEmail author  Michael?N.?Fried 《Journal of Science Education and Technology》2005,14(3):315-336

This essay considers the question of why we should teach science to K-2. After initial consideration of two traditional reasons for studying science, six assertions supporting the idea that even small children should be exposed to science are given. These are, in order: (1) Children naturally enjoy observing and thinking about nature. (2) Exposing students to science develops positive attitudes towards science. (3) Early exposure to scientific phenomena leads to better understanding of the scientific concepts studied later in a formal way. (4) The use of scientifically informed language at an early age influences the eventual development of scientific concepts. (5) Children can understand scientific concepts and reason scientifically. (6) Science is an efficient means for developing scientific thinking. Concrete illustrations of some of the ideas discussed in this essay, particularly, how language and prior knowledge may influence the development of scientific concepts, are then provided. The essay concludes by emphasizing that there is a window of opportunity that educators should exploit by presenting science as part of the curriculum in both kindergarten and the first years of primary school.  相似文献   

ADAPT<Superscript>IT</Superscript>: Tools for training design and evaluation     

Marcel?B.?M.?de?CroockEmail author  Fred?Paas  Henrik?Schlandbusch  Jeroen?J.?G.?van?Merri?nboer 《Educational technology research and development : ETR & D》2002,50(4):47-58

This article describes a set of computerized tools that support the design and evaluation of competency-based training programs. The training of complex skills such as air traffic control and process control requires a competency-based approach that focuses on the integration and coordination of constituent skills and transfer of learning. At the heart of the training are authentic whole-task practice situations. The instructional design tools are based on van Merriënboer's 4C/ID^* methodology (1997). The article describes a training design tool (Core) that supports the analysis and design for competency-based training programs and an evaluation tool (Eval) that supports the subsequent revision of this training design.  相似文献   

An adaptive strategy for controlling chaotic system     

曹一家  张红先 《浙江大学学报(A卷英文版)》2003,4(3):258-263

This paper presents an adaptive strategy for controlling chaotic systems. By employing the phase space reconstruction technique in nonlinear dynamical systems theory, the proposed strategy transforms the nonlinear system into canonical form, and employs a nonlinear observer to estimate the uncertainties and disturbances of the nonlinear system, and then establishes a state-error-like feedback law. The developed control scheme allows chaos control in spite of modeling errors and parametric variations. The effectiveness of the proposed approach has been demonstrated through its applications to two well-known chaotic systems: Duffing oscillator and Rössler chaos.  相似文献   

Developing networks of grass-roots science curriculum action     

Carmel McNaught  Dianne Raubenheimer  Margaret Keogh  Rob O'Donoghue  Jim Taylor 《Research in Science Education》1992,22(1):291-298

This paper describes an ongoing process of participatory curriculum development. It outlines some of the tensions which need to be explored in science curriculum development: debates about the nature of science, of society, of school science content and of learning theories. The process whereby action can arise from this debate is also explored. An example will be outlined of a network of science curriculum action which has developed from the work of a range of science education projects in Natal, South Africa. Specializations: science curriculum development from primary to tertiary level. Specializations: inservice primary science teacher development. Specializations: inservice teacher development, biology education. Specializations: environmental education, teacher development. Specializations: environmental education, teacher development.  相似文献

Who'd be an English teacher?     

Anne Turvey Corresponding author 《Changing English: An International Journal of English Teaching》2005,12(1):3-18

This paper is about the progress of newly qualified teachers of English in London classrooms. Using a case‐study approach, it explores the ways teachers' knowledge of their subject is developed in specific situations and in relation to particular learners. In contrast to media representations of successful teaching that focus on questions of personality and inspiration, the picture of progress offered here is one of negotiation and accommodation, leading to fundamental change and to new understanding of the content and purposes of English.  相似文献   

The Role of Parents and Community in the Education of the Japanese Child     

Heidi?KnipprathEmail author 《Educational Research for Policy and Practice》2004,3(2):95-107

In Japan, there has been an increased concern about family and community participation in the childs education. Traditionally, the role of parents and community in Japan has been one of support and less one of active involvement in school learning. Since the government commenced education reforms in the last quarter of the 20th century, a more active role for parents and the community in education has been encouraged. These reforms have been inspired by the need to tackle various problems that had arisen, such as the perceived harmful elements of societys preoccupation with academic achievement and the problematic behavior of young people. In this paper, the following issues are examined: (1) education policy and reform measures with regard to parent and community involvement in the childs education; (2) the state of parent and community involvement at the eve of the 20th century.  相似文献   

Parental concerns and priorities in the education of disabled students     

Margaret A. Steinberg 《International Journal of Disability, Development & Education》1983,30(1):77-85

During a conference organized as part of I.Y.D.P., parents of the disabled from throughout Queensland attempted to identify the primary needs they experienced in coping with a disabled child in the family. Recommendations were made concerning the provision of services which would help to alleviate these needs. Issues and recommendations concerning education, including educational rights, legislative and financial considerations, teacher education, and the adequacy of educational services, are discussed in this paper. The dearth of a range of appropriate post‐school options was of crucial import; provision of continuing education services for disabled school leavers, including minimally handicapped students integrated into regular classes, is seen as an urgent requirement. Co‐operative planning and service provision should be given priority status by special education authorities, tertiary institutions and employment departments and agencies.  相似文献   

What Is Wrong with Practicum?: some reflections     

Margaret Edwards 《Asia-Pacific Journal of Teacher Education》1993,21(1):33-43

The purpose of this study was to examine students’ perceptions of previously identified negative aspects of practicum during preparation courses for careers in the field of early childhood education. Students at each of three year levels of the course earlier had been surveyed using a Likert‐type instrument following recent practicum experiences. Item frequency analysis was conducted for each separate year group's responses and for the combined group. Analysis of data from the combined responses included item properties, item‐scale relationships, scale properties and instrument factor analysis. Results of factor analysis revealed seven interpretable stressors, the most serious being the cluster labelled ‘physical demands’. The 10 most negative aspects for each year level (i.e. items with the lowest means) were compiled in a subsequent instrument similar to the original but also including a request for explanatory comments following each item. These three instruments were administered at the end of the same year. Student comments on the latter instruments clarified the statistical results and are presented here in the categories of ‘demands on students’, Hime and energy’, ‘coping with written requirements’, and ‘conforming with mistrusted practices’. Reflections on the implications of this illumination of statistical analysis are then presented.  相似文献
