Scientific activity tends to reflect particular worldviews and their associated value outlooks; and scientific results sometimes have implications for worldviews and the presuppositions of value outlooks. Even so, scientific activity per se neither presupposes nor provides sound rational grounds to accept any worldview or value outlook. Moreover, in virtue of reflecting a suitable variety of worldviews and value outlooks, perhaps including some religious ones, science is better able to further its aim. An extended argument is made that, although the materialist worldview has de facto been widely associated with the development of modern science, the scope of scientific inquiry is improperly limited when constraints, derived from materialism, are generally placed upon admissible scientific theories. Some implications for science education are sketched in the conclusion. 相似文献

The basic anatomy of an experimental design is used as an expository introduction to the examination of several repeated measures experiments described in recent pages of this and other journals. This examination reveals problematic issues concerning some common design and analysis features of such experimental designs. In particular, the hierarchical structures and/or presence of time trends is highlighted. These issues are discussed in an attempt to assist researchers to recognize such problems, to avoid the associated difficulties in the future, and to exploit the advantages of sound design with appropriate, efficient and informative analysis. While alternate reanalyses of the data of these experiments might reveal the conclusions to be unaffected by such issues, researchers should still be cautious. In retrospect, such occurrences should be seen as fortuitous, not as justification for inefficient or less informative analyses. More importantly, such reanalyses could reveal more enlightening information, and I argue that if a design permits such information to be discovered, then it behoves researchers to perform such analyses and to make such discoveries. 相似文献

ABSTRACTSeldom have comparative studies of educational assessment systems been undertaken, especially regarding their standard setting procedures. This study examines the effects of governance structures on the power relations in standard setting in the dominant school-leaving or university-entrance examinations. We present acritical analysis of the published research and policy documents, including sense-checking with senior assessment practitioners from 22 jurisdictions. The nature of standard setting systems in three cases of Ireland, the USA and India are described in detail to showcase the differences between the following three models of governance systems: nationalised, commercial market and quasi-market. The contribution of this article, then, is to describe the three models of governance systems, to classify the 22 jurisdictions using the three models, and to generate propositions inductively. Thus, the article provides aconceptual basis for extension of this work to other cases to advance the literature cumulatively by theory-building. 相似文献

An attempt was made to train 9 homing pigeons to respond to the presence or absence of bar magnets by turning either left or right after flying the length of a 20-ft outdoor flight cage. During initial training, color cues were placed in front of feeding stations on the left and right sides of the cage. The color cues were paired with magnetic cues by attaching either bar magnets or brass bars to the backs of the birds. The color cues were then deleted, leaving only the magnetic cues. Each pigeon received about 300 trials of color training followed by about 200 trials of magnet testing. When only magnetic cues remained, none of the pigeons were able to choose the correct feeder at greater than chance levels of probability. 相似文献

Subgrouping poor readers on the basis of individual differences in reading-related abilities 总被引:1,自引:0,他引:1
The present study investigated the use of the Reading Component Model to subgroup poor readers. A large sample of poor readers was identified in second grade and subgrouped on the basis of relative strengths and weaknesses in word recognition and listening comprehension. Although homogeneous subgroups were not identified, poor readers could be classified into four subgroups that differed significantly in reading-related abilities. Further analyses showed that poor readers' strengths and weaknesses in listening comprehension, and to a lesser extent in word recognition, were foreshadowed by their abilities on related kindergarten measures. Follow-up testing in the fourth grade indicated that poor readers' individual differences in word recognition and listening comprehension were consistent and that subgroups were moderately stable. The implications of these results for the assessment and remediation of reading disabilities are discussed. 相似文献
