Water-deprived rats were given a single exposure to saccharin and LiCl, either paired or unpaired. Half the subjects then received three saccharin-only exposures (extinction) in the training enclosure, followed by a single LiCl-only presentation (unconditioned stimulus reinstatement) 8 days after conditioning. The remaining subjects received six saccharin-only exposures, followed by LiCl reinstatement 13 days after conditioning. In both cases LiCl reinstatement occurred outside the training/test context. Appreciable recovery from extinction was observed after the partial loss of taste aversion obtained with three extinction sessions and the 8-day conditioning-reinstatement interval, but not after the asymptotic loss of taste aversion obtained with six extinction sessions and the 13-day conditioning-reinstatement interval. Conditioned taste aversions appear to be similar to more traditional associations with respect to both extinction and reinstatement-induced recovery from extinction. The results are discussed with reference to the event-memory, contextual-conditioning, and facilitated-retrieval hypotheses of postextinction reinstatement effects. 相似文献

This paper explores the limitations of empathy for the formation of community, particularly within social justice education. I begin with a discussion of the major tension within the idea of community — that it is founded at once on commonality and difference. Building in particular upon the work of Emmanuel Levinas, the paper articulates an understanding of community as a signifying encounter with difference that is not founded upon knowledge about the other, but upon a being-for and feeling-for the other. Focusing upon the explicitly educational commitment to working out forms of relationality conducive to establishing community and social justice across social differences, I ask how might teaching with ignorance, as opposed to teaching for empathy, bring us closer to the being-for others that marks our ethical engagement with other people and engenders our responsibility to the collective? 相似文献

This article analyses the extent to which archival exemptions for historical, scientific and statistical research in privacy
legislation support preservation in selected European Union countries, and comparable aspects of Australian, American and
Canadian law within a legal, ethical and digital archival perspective. The authors recommend that the further processing of
personal data under data protection law be given a wider scope of interpretation for archival preservation purposes in both
the public and private sector, coupled with the use of researcher and archival codes in relation to access to personal data.
They also recommend early appraisal and integration of privacy with freedom of information and archival regimes.

Narratives are one of the most powerful teaching tools available and are often regarded as central to the learning process. We investigate the role of narrative in adult learning in library instructional contexts, introducing the concepts of micro- and macro-narratives and illustrating these ideas using relevant teaching examples. Macro-narratives are stories that are common across many cultures and contain universal themes and lessons. Micro-narratives are stories that are uniquely relevant to the members of a particular group. We argue that both types can be used to create meaningful library learning experiences. 相似文献

This investigation examines how the process of instructional consultation (IC) supports consultees' problem-solving and fosters change in how the consultees understand pertinent work problems. The setting was a mid-Atlantic elementary school's Instructional Consultation Team, and the participants were 13 case manager consultants and 5 teacher consultees. A micro-ethnographic research approach was used and 4 primary sources of data collected: interviews, direct observations, consultation documents, and IC training documents. Analysis of the data uncovered 4 general themes related to the participants' problem-solving and evolving understanding of the work issues. In the discussion, the question of how IC is a constructive process that promotes consultees' development is considered. 相似文献

This position paper proposes the enhancement of teacher and student learning in science classrooms by tapping the enormous
potential of information communication and technologies (ICTs) as cognitive tools for engaging students in scientific inquiry.
This paper serves to challenge teacher-held assumptions about students learning science ‘from technology’ with a framework
and examples of students learning science ‘with technology’. Whereas a high percentage of students are finding their way in
using ICTs outside of school, for the most part they currently are not doing so inside of school in ways that they find meaningful
and relevant to their lives. Instead, the pedagogical approaches that are most often experienced are out-of-step with how
students use ICTs outside of schools and are not supportive of learning framed by constructivism. Here we describe a theoretical
and pedagogical foundation for better connecting the two worlds of students’ lives: life in school and life outside of school.
This position paper is in response to the changing landscape of students’ lives. The position is transformative in nature
because it proposes the use of cyber-enabled resources for cultivating and leveraging students new literacy skills by learning
‘with technology’ to enhance science learning. 相似文献

Radiological images show anatomical structures in multiple planes and may be effective for teaching anatomical spatial relationships, something that students often find difficult to master. This study tests the hypotheses that (1) the use of cadaveric computed tomography (CT) scans in the anatomy laboratory is positively associated with performance in the gross anatomy course and (2) dissection of the CT‐scanned cadaver is positively associated with performance on this course. One hundred and seventy‐nine first‐year medical students enrolled in gross anatomy at Boston University School of Medicine were provided with CT scans of four cadavers, and students were given the opportunity to choose whether or not to use these images. The hypotheses were tested using logistic regression analysis adjusting for student demographic characteristics. Students who used the CT scans were more likely to score greater than 90% as an average practical examination score (odds ratio OR 3.6; 95% CI 1.4, 9.2), final course grade (OR 2.6; 95% CI 1.01, 6.8), and on spatial anatomy examination questions (OR 2.4; 95% CI 1.03, 5.6) than were students who did not use the CT scans. There were no differences in performance between students who dissected the scanned cadavers and those who dissected a different cadaver. These results demonstrate that the use of CT scans in medical gross anatomy is predictive of performance in the course and on questions requiring knowledge of anatomical spatial relationships, but it is not necessary to scan the actual cadaver dissected by each student.
