The McCarthy Scales of Children's Abilities (MSCA) were factor analyzed for a group of 6- to 8 1/2-year-old children referred for school-related problems. The sample was composed of 300 rural eastern North Carolina public school children with a mean GCI of 88.1. Evidence was found for factors similar to three of the six MSCA Scales: General Cognitive, Verbal, and Motor. Coefficients of congruence were computed and compared with earlier analyses of the standardization data. The results were interpreted as generally supporting the MSCA's validity with children experiencing problems in school. Implications for interpretation of the MSCA Scales were presented. 相似文献

Previous factor analyses of the K-ABC for school-age children have offered varying degrees of support for the test, depending on which subtests have been analyzed. Further, most previous analyses have involved only children from the standardization sample. Here, K-ABC scores for 585 school-age children referred for psychological evaluation were factor analyzed. Results of the analysis of K-ABC MP tests were quite consistent with those of previous analyses and with the structure of the test itself. The factor structure of the MP and Achievement tests together was also consistent with previous analyses and, like those analyses, was somewhat less consistent with the theoretical structure of the K-ABC; the factors found could be interpreted from several perspectives. As in analyses of the standardization data, the Achievement tests appear to be better measures of general intelligence for referred children than do the MP scales. Thus, while it appears that the K-ABC factor structure is quite consistent for both normal and exceptional children, the meaning and names of factors found are open to interpretation. 相似文献

Previous studies have investigated how individuals reach an expert level by counting the number of hours engaged in specific practice types. Here we sought to understand and compare the microstructure (e.g. practice tasks undertaken) of these practice hours experienced by elite and sub-elite British rugby league players. Semi-structured interviews explored the practice experiences of eight international and eight domestic level players. A two-staged thematic analysis was used to interpret the data. The analysis revealed that both player groups experienced a rich and narrow landscape of affordances and were exposed to early diversification of sports experiences during childhood. Differences were identified in domestic level players’ experiences of amateur and professional sports, where episodes of negative developmental environments were reported. International players’ practice experiences revealed differences in their professional careers, where exposure to scenario-based practice and dynamic learning environments were reported. The findings suggest that insights from ecological dynamics provide a suitable theoretical framework to guide coaches in the design of practice environments that should consider the physical, psychological, emotional and social dimensions of expertise acquisition. 相似文献

Religious beliefs in science classrooms 总被引:3,自引:0,他引:3
The question of the relationship between science and religion assumes importance for many secondary school students of science,
especially but not exclusively for those in Christian schools. Science as presented in many school classrooms is not as objective
and value free as it might seem on first examination, nor does it represent adequately the range of beliefs about science
held by students and teachers. This paper reports part of a larger research study into beliefs about science and religion
held by students, teachers and clergy in a Lutheran secondary school. Results indicate that participants in the study was
the relationship between science and religious belief in ways unforeseen and unappreciated by traditional school science programs.
The stories of selected participants are told and they frame a discussion of implications of the study for science teaching. 相似文献

The factor structure of five self‐concept scales from a hierarchical, multidimensional theoretical model was investigated. The Coopersmith Self‐Esteem Inventory, Multidimensional Self Concept Scale, Piers‐Harris Self‐Concept Scale, Self‐Esteem Index, and the Tennessee Self‐Concept Scale were administered to 221 students in Grades 5 through 8 in a counter‐balanced administration format. The five scales each yielded strong general factors and six dominant factors that coincide with the proposed theoretical model, which reflects social, affect, competence, academic, family, and physical self‐concepts. © 2000 John Wiley & Sons, Inc. 相似文献

Students' views of the nature of scientific knowledge have been recognized as an important component of science learning environments. In this study, we analyze an extensive data base consisting of 23 students' written and oral discourse about ontology, epistemology, and sociology of scientific knowledge collected over a 15-month period in the context of two consecutive junior- and senior-level physics courses. Over a 2-month period at the beginning of the second year, students read, reflected on, and talked about a text which discusses epistemology in the context of physics. Our study shows that students drew on nine types of discursive resources to support their ontological, epistemological, and sociological claims. Toward the end of the study, the range and number of supportive statements had increased. Simultaneously, few students changed their ontological and sociological claims, but a considerable number changed their epistemological claims. Two case studies illustrate the development of student discourse in the course of the study. © 1997 John Wiley & Sons, Inc. J Res Sci Teach 34 : 145–179, 1997. 相似文献

The OPEC price increases initiated in 1973 resulted in intense international preoccupation with a shortage of energy and this has tended to overshadow concern for the continuing shortage of food in many parts of the world. Yet the need for greater and more efficient food production is as pressing as ever, and in achieving this, the development of new chemical aids for preventing plant diseases is very important. Annual loss in world crops caused by disease is estimated to be of the order of £60 000 million, mostly due to fungal infections. 相似文献
