Interviewing, as an information‐gathering tool for prospective teachers of the deaf, was used to document the perspectives which deaf children, their parents, teachers and administrators bring to the mainstreaming process. Data revealed the different, and sometimes competing priorities of mainstreaming participants; these priorities are discussed in terms of their impact upon the success or failure of the mainstreaming process and the preparation responsibilities of teacher training programs. 相似文献

This paper presents measures of faculty salary compression for 1993 and 1999 based on national, rather than institutional-level, data. Using a recently developed technique and two national faculty surveys, actual junior to senior salary ratios are derived as well as predicted salary ratios that represent what the salary ratios would be if junior and senior faculty were similarly compensated for their productive traits. The analysis, which considers three alternative definitions of junior faculty and stratifies results by institutional type, produces an overall finding of no salary compression. A limited number of disciplines, including business and economics, however, do exhibit signs of salary compression. 相似文献

This study examined the effects of rewards on the ideational fluency of 75 preschool children. Assigned to a reward or nonreward condition, the children were administered two ideational fluency tasks, Unusual Uses and Pattern Meanings. Analyses revealed a significant main effect for reward on the ideational fluency components of originality, total fluency, and flexibility. In all cases the rewarded subjects scored lower than the nonrewarded group. These findings support the growing body of evidence that rewards are detrimental to creative functioning. 相似文献

Pigeons were trained on two independent tasks. One involved red and yellow hues, the other involved blue and green hues. For half of the birds, the two tasks were the same (i.e., both tasks were either matching-to-sample, or oddity-from-sample). For the remaining birds, the two tasks were different (i.e., one task was matching-to-sample; the other task was oddity-from-sample). Following acquisition, the pigeons were exposed to test trials on which either the correct or the incorrect comparison hue was replaced with one of the hues from the other task. On yellow-sample trials and on green-sample trials, the pigeons performed as if they had a common code for yellow and green. When there was one comparison available that was appropriate to the “yellow/green” code, performance remained high; but when either both comparisons or neither comparison was appropriate to the “yellow/green” code, performance dropped. The pigeons also tended to code red samples as green and to code blue samples as yellow. The results indicate that pigeons can categorically code colors under conditions that rule out a failure to discriminate among the colors. 相似文献

The term noise is used to describe fluctuations about the mean deterministic stationary value of a physical quantity. It is
now being increasingly realised that noise is an important ingredient to bring order in dynamical processes. Though it appears
counterintuitive, noise seems to help in directing transport processes in biological systems at the molecular level. In Part
2 of the article, we discuss some more examples of noise assisted directed motion. 相似文献

The use of the Internet in the classroom has often been characterized as a practice that disconnects the teacher from traditional forms of externally imposed influence. This paper examines this assertion by mapping the emerging field of cybereducation and considering how endemic knowledge is contextualized by national curricular authorities. The field theories of Pierre Bourdieu and Basil Bernstein are employed in order to demonstrate the relationship between expert discourse and classroom pedagogy, using the National Grid for Learning (NGfL) as a case study. This attempt to capture the dynamics of cybereducation ultimately suggests how this emergent intellectual field’s fragmentation and decoupling from State education forces offers policymakers the capacity to influence use. Progress of the UK government in integrating knowledge from an emergent educational field with its incumbent priorities is gauged, demonstrating the way in which national education officials have attempted to constrain potential departures from unregulated, officially mandated curriculum. 相似文献

AbstractUniversity rankings are increasingly important internationally, and in the UK include a sustainability ‘Green League’. However, there is little evidence about experiences of studying in ‘sustainable universities’. We report an empirical study at five universities in varied positions in the Green League, exploring students’ energy literacy, environmental attitudes and perceptions of their institution’s energy-saving efforts. Although the link to energy literacy is not clear, findings suggest that there are significant differences between students’ environmental attitudes at universities placed at different points in the league. In addition, students at higher ranked universities are more positive about their university’s energy-saving efforts, suggesting that these institutions may exhibit more overt manifestations of sustainability. This is important since students report being more likely to choose energy-conservation behaviours if there is visible representation of energy use. The study is the first to attempt a comparison between universities at different positions in a sustainability ranking. 相似文献
