The study examined (1) the public's reactions to the philosophical justifications for merit vs. preferential selection, and (2) the effect of information frame (i.e. ‘merit’, ‘preferential’and ‘diversity’frames) and informant gender on people's views on preferential selection. Results show that in general the public supported merit selection and opposed the preferential practice and that their reactions to the justifications for a selection practice determined the level of support for (or opposition to) that practice. In addition, people's support for merit selection was weakened under the preferential-frame-female-informant condition; their opposition to preferential selection was also reduced when a male informant advocated the advantages of the preferential practice by using the term diversity-based selection instead of preferential selection. Results were discussed in the context of the social influence literature.  相似文献

Recent studies have documented the increasing trend among school districts toward adopting full inclusion as the predominant model for serving students who qualify for special education services. Although these data may suggest that a paradigm shift has already taken place and that a consensus of opinion has been achieved, several organizations representing students with specific disabilities continue to support a continuum of placement options. This paper challenges a one size fits all approach to special education, and highlights the importance of considering the individual characteristics of students. The relevance of research on full inclusion, as well as methodological issues that limit generalizability of findings related to student outcomes, are discussed. The radical perspective of full inclusion is rejected in favor of an approach that emphasizes the complexities of placement decisions.  相似文献

Many have asked how and why feminist theory makes a distinctive contribution to bioethics. In this essay, I outline two ways in which feminist reflection can enrich bioethical studies. First, feminist theory may expose certain themes of androcentric reasoning that can affect, in sometimes crude but often subtle ways, the substantive analysis of topics in bioethics; second, it can unearth the gendered nature of certain basic philosohical concepts that form the working tools of ethical theory.  相似文献

The present study examined the effects of an error correction strategy on the spelling accuracy of students with emotional and/or learning disabilities. The strategy, which asked students to spell a word, view a correct model, and then correct their errors, was compared to a traditional strategy that asked students to write words three times each while viewing a correct model. Results showed that students learned more words in the error correction condition than in the traditional condition. The error correction treatment was shown to be an effective strategy that reduced the number of repetitive spelling practice trials, and was preferred by students.  相似文献

This study compared the effectiveness and efficiency of simultaneous prompting with and without error correction during daily probe sessions in teaching science vocabulary words. The teacher presented the vocabulary word definitions as instructive feedback during training sessions. Five 16–17 year old students with disabilities participated in an adapted alternating treatments design that evaluated the simultaneous prompting strategy, error correction and instructive feedback. Instruction occurred in a group format using choral responding. The results indicate that (a) all students learned to read the vocabulary words, (b) simultaneous prompting with error correction was slightly more efficient for three of the five subjects in learning the targeted words, and four of the five students made fewer errors in this condition, (c) all students preferred simultaneous prompting with error correction over simultaneous prompting without error correction, (d) words mastered in both conditions generalized equally, (e) there were minimal differences between the two conditions in the collected maintenance data, and (e) students experienced only minimal improvement in their ability to define vocabulary words (instructive feedback). Discussion focuses on issues for further research and implications for instructional practice with simultaneous prompting, error correction and instructive feedback.  相似文献

This paper examines the arguments presented by the Roman Catholic Bishops in their 1993 Pastoral Resolution, Comprehensive Health Care Reform: Protecting Human Life, Promoting Human Dignity, Pursuing the Common Good, concerning health care reform. Focusing on the meaning of equality in health care and traditional Roman Catholic doctrine, it is argued that the Bishops fail to grasp the force of the differences among persons, the value of the market, and traditional scholastic arguments concerning obligatory and extraordinary health care. To attempt to equalize the distribution of health care would be ruinous. A more traditional understanding of Christian thought reveals an acceptance of inequality in health care distribution and a bias against using the secular state to coerce a solution to such concerns for social justice.  相似文献
