This paper investigates the importance of knowing whether or not deaf and hard-of-hearing students have one or more deaf or hard-of-hearing parents. As noted by Mitchell and Karchmer (2004), deaf and hard-of-hearing school-age children and youth in the United States with at least one parent identified as "hearing impaired" are nearly evenly split between having at least one deaf parent and having at least one hard-of-hearing parent. However, there is no literature on the importance, if any, of this distinction. Findings from the investigation reported herein suggest that the distinction between having a deaf versus a hard-of-hearing parent is quite substantial, particularly as it pertains to the use of signing in the home. Further, signing in the home, which is reliably predicted by parental hearing status, is a significant predictor of the school setting in which the student is currently placed and the instructional use of signing in the classroom. Limitations related to the available measure of parental hearing status are discussed. 相似文献

A glass ceiling for women still exists in academia after two decades of equal employment opportunity (EEO) legislation in Australia. There are complex factors that when combined make gender inequity in the higher education sector highly resistant to change. Using personal histories as a reflexive device, the paper makes explicit the embedded male patterns of behaviour in academia that operate beneath the façade of policies and rules put into place to counter inequity. In particular, the paper focuses on the cognitive dissonance individuals experience due to the disparity between formal organizational policies promoting equity, such as workload allocations, and perceptions of the unequal opportunities for women and men. Using social identity theory and the leader member exchange (LMX) framework, the daily experiences of three academic women are interpreted, the impediments to equality identified, and suggestions made for more fundamental change to gendered organizational structures within academia. The analysis of such behaviours shows that the traditional emphasis of EEO legislation on formal policies and procedures to bring about gender equity in academia needs to be accompanied by cultural change programs that make explicit and challenge behaviours that reproduce and reinforce male hegemony in academia. 相似文献

Pigeons learned to peck a keylight (S2) when it was paired with a stimulus (S1) that already evoked keypecking. Control procedures showed that S2 acquired control over responding because it was paired with S1 and because S1 had a conditioning history, thereby supporting the claim that S2 was a second-order conditioned stimulus. Second-order conditioning occurred as rapidly when S1 was a keylight as when it was a tone. Test procedures showed that after second-order conditioning, responding to S2 was markedly debilitated by the extinction of responding to S1, indicating that the ability of S2 to evoke a response importantly depends upon the continued ability of S1 to do so. Our demonstration that directed motor action in the pigeon is susceptible to second-order conditioning suggests a new interpretation of conditioned reinforcement in instrumental learning. Our demonstration that the effectiveness of S2 depends upon the continued effectiveness of S1 indicates that S-S associations are formed in this version of the second-order conditioning experiment. 相似文献

Using a self-report survey, this investigation described university employees' reactions to the publication of their salaries in a local campus newspaper. Correlational analyses indicated associations between impact of the disclosure and salary level, salary equity/satisfaction, instrumentality of performance-reward outcomes, internal salary attributions, and salary discussion. Further analysis found differences in respondent perceptions to be contingent upon job category (academic, professional, and support staff) and faculty level. Qualitative analysis suggested that individual responses to the salary disclosure took various forms: no effect at all, planning to leave one's job, attempting to correct salary inequities, reducing personal effort, and working harder. The findings are discussed in relation to the literature on open pay systems and invasion of privacy.This paper was presented in part at the 43rd Annual Meeting of the Academy of Management, Dallas, Texas, August 1983. 相似文献

In the context of escalating criticism of university‐based teacher education across the world, a clear need exists for informed defence of the field and the profession as well as critical evaluation of both teacher education and schooling. This paper takes up the issue of the ‘outcomes question’ in this regard, arguing the case for a strong focus on social justice as the necessary complement to an ongoing concern with academic excellence and rigor. It argues the need for teacher educators and others to look closely at the different ways that educational outcomes are currently being defined and for these differences to be made more openly and widely available for criticism and discussion. The paper seeks to contribute to debate regarding the role and renewal of teacher education, in specific relation to widespread standards movements and the public good, and the conduct and governance of education more generally. 相似文献

Learning with hands-on experiments can be supported by providing essential information virtually during lab work. Augmented reality (AR) appears especially suitable for presenting information during experimentation, as it can be used to integrate both physical and virtual lab work. Virtual information can be displayed in close spatial proximity to the correspondent components in the experimentation environment, thereby ensuring a basic design principle for multimedia instruction: the spatial contiguity principle. The latter is assumed to reduce learners' extraneous cognitive load and foster generative processing, which supports conceptual knowledge acquisition. For the present study, a tablet-based AR application has been developed to support learning from hands-on experiments in physics education. Real-time measurement data were displayed directly above the components of electric circuits, which were constructed by the learners during lab work. In a two group pretest–posttest design, we compared university students' (N = 50) perceived cognitive load and conceptual knowledge gain for both the AR-supported and a matching non-AR learning environment. Whereas participants in both conditions gave comparable ratings for cognitive load, learning gains in conceptual knowledge were only detectable for the AR-supported lab work. 相似文献

The relevant literature indicates strong need for novelty, change and exploration in creative people. This study investigated the relationship between demand for stimulation in 100 high school students and their creativity in problem solving situations. A significant relationship was found between the demand for varied stimulation (adventure, novelty, risk) and cognitive flexibility and complexity, nonconformism and spontaneity, as well as tolerance for cognitive incompatibilities. The data help to explain the conditions that are particularly favourable for these people to function in their social environment. 相似文献
