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

The goal of this study was to define the construct and establish the validity of disciplinary literacy, which has recently gained attention from the implementation of the Common Core State Standards (National Governors Association Center for Best Practices & Council of Chief State School Officers in Common Core State Standards for English language arts & literacy in history/social studies, science, and technical subjects [PDF]. Authors, Washington, DC, 2010). After defining disciplinary literacy in the four core disciplines of English language arts, science, history and social studies, and mathematics, scales were developed and administered to a snowball sample of professionals nationwide, with 857 respondents. The data showed evidence of disciplinary literacy as a multidimensional construct with three related factors: source literacy, analytic literacy, and expressive literacy. Based on EFA and CFA results, we can conclude that there are at least three types of literacy in operation among the four core disciplines. The three factors of literacy varied significantly by the four core disciplines of English/language arts (ELA), science, history and social studies, and mathematics, supporting the notion that each discipline uses literacy uniquely. This is the first study of its kind to attempt to define, quantify, and validate the construct of disciplinary literacy. 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

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
