This paper reports some of the findings of the Procedural and Conceptual Knowledge in Science (PACKS) project. It documents children's ides about the reliability of experimental data, an important element of their understanding of science procedures. These ideas were elicited using a written survey instrument completed by over 1000 students aged 11, 14 and 16, chosen to be representative of the full ability range. The results show progression with age in understanding of empirical data. A range of ideas about the function of repeat measurements, how to handle repeat measurements and anomalous readings, and the significance of the spread of a set of repeated measurements emerge and are discussed. 相似文献

With the aim of determining both the acute and the chronic effects of textured insoles on the ankle discrimination and performance ability of dancers, 60 ballet dancers from the Australian Ballet School, aged 14–19 years, were divided into three groups (two intervention groups and a control group), age- and level-matched. In the first 5 weeks (weeks 1 to 5), the first intervention group (GRP1) was asked to wear textured insoles in their ballet shoes and the second intervention group (GRP2) was not given textured insoles to wear. In the next 5 weeks (weeks 6 to 10), GRP2 was asked to wear the same type of textured insoles and GRP1 did not wear the textured insoles. The control group (CTRL) did not wear textured insoles during the whole 10 weeks. All participants were tested preintervention, after 5 weeks and after 10 weeks for ankle discrimination score (AUC scores). Dance performance was assessed by 5–7 dance teachers. Pre-to-post change in AUC scores was significantly greater for the groups wearing insoles than for the controls (P = .046) and the size of pre-to-post changes did not differ between the two intervention groups (P = .834). Significant correlation was found between ankle discrimination score and performance scores, using the textured insoles (r = .412; P = .024). In conclusion, the stimulation to the proprioceptive system arising from textured insoles worn for five weeks was sufficient to improve the proprioceptive ability and performance ability of ballet dancers. 相似文献

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

Researchers in the field of gifted education are becoming increasingly aware that a variety of research approaches can make contributions to research on giftedness. This paper describes task analysis, a research methodology derived from counseling process research. Task analysis appears to be a useful research approach for building theoretical models of how therapeutic and educational interventions can facilitate positive changes in gifted children. The paper traces the historical development of task analysis methodology, describes the steps involved in conducting a rational‐empirical task analysis of change processes, and provides an example of how task analysis methodology might be applied to investigations of change processes in the field of gifted education. 相似文献

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

In her article “A Possible ‘Orality’ for Science?” (Interchange, Vol. 23, No. 3, pp. 227–244), Rampal argues that science can be made more relevant to students if its language is reformed and replaced by one that contains elements drawn from oral cultures. There is some point to this policy proposal, but it fails to note that the dispassionate and impersonal prose of science has its own function in the on-going practice of science. The real task for the teacher should not be reforming the language of science but rather using oral culture to lead students in the excitement of scientific theories and the joys of scientific research, bringing them in the end to a mastery of the prose style that the scientific community has found serves well its goal of increasing our knowledge of laws of nature. 相似文献
