Reinstatement of postresponse stimuli prior to reward in delayed-reward discrimination learning by pigeons     

Patricia B. Cronin 《Learning & behavior》1980,8(3):352-358

Delayed-reward learning in pigeons was examined using a simultaneous red-green visual discrimination task in which the conditions during the delay interval were varied between groups. The nondifferential group received training in which the stimulus present during the 1-min delay was the same following a peck on the correct and incorrect colors. The other three groups received 1-min delay training in which different stimuli occurred in the delay interval following correct and incorrect choices. The differential group received continuous, differential stimuli during the delay. The reinstatement group received the differential stimuli in the 10 sec immediately following the choice and during the last 10 sec of the delay. The reversedcue group was treated in the same way, except that the 10-sec delay stimulus immediately following an incorrect response was also presented for 10 sec prior to reward on correct choices, and the stimulus following a correct response also occurred 10 sec before nonreward on incorrect choices. Nondifferential birds failed to learn the discrimination, while differential and reinstatement birds learned it readily. The reversed-cue birds learned to choose the incorrect stimulus. Differential and reinstatement birds showed no decrement in performance when the delay was increased to 2 min. These findings suggest that similarity of prereward and postresponse delay stimuli controls choice responding in long-delay learning, a finding compatible with both memorial and conditioned reinforcement interpretations.  相似文献   

Curiosity, interest and engagement in technology-pervasive learning environments: a new research agenda     

Marilyn P. Arnone  Ruth V. Small  Sarah A. Chauncey  H. Patricia McKenna 《Educational technology research and development : ETR & D》2011,59(2):181-198

This paper identifies the need for developing new ways to study curiosity in the context of today’s pervasive technologies and unprecedented information access. Curiosity is defined in this paper in a way which incorporates the concomitant constructs of interest and engagement. A theoretical model for curiosity, interest and engagement in new media technology-pervasive learning environments is advanced, taking into consideration personal, situational and contextual factors as influencing variables. While the path associated with curiosity, interest, and engagement during learning and research has remained essentially the same, how individuals tackle research and information-seeking tasks and factors which sustain such efforts have changed. Learning modalities for promoting this theoretical model are discussed leading to a series of recommendations for future research. This article offers a multi-lens perspective on curiosity and suggests a multi-method research agenda for validating such a perspective.  相似文献

Creating Collaborative Partnership With Local Churches to Improve Academic Performance of K-12 Public Schools     

Patricia A. Green-Powell  ;Adriel A. Hilton  ;Crystal L. Joseph 《美中教育评论》2011,(1):64-69

Since their founding, the Black churches have strived to implement and fulfill their missions. These institutions acknowledge the importance to become actively involved in the community as well as engaged in the lives of young people. Black churches are faced with unique challenges every day, however, they provide significant number of resources to the communities at large. In this study, we examine the role of partnerships through local churches and its impact on low performing schools using qualitative methodology. Research shows that low performing schools are influenced positively by partnerships with Black churches.  相似文献   

The Perceptions of Administrators Concerning the One Florida Initiative     

Adriel A. Hilton  ;Patricia A.Green-Powell  ;Crystal L. Joseph  ;Linda G. Knight 《美中教育评论》2011,(2):233-238

The purpose of this study was to discover the perceptions of Florida law school administrators on the impact of the OFI （one Florida initiative） and the addition of two MSI （minority serving institution） law schools on diversity in Florida＇s legal profession. This research explored the impact of Governor Bush＇s EO （executive order） on diversity within the SUS （state university system） of Florida law schools. Further, this study examined the impact of the creation of two MSI law schools after implementation of the OFI, as perceived by the administrators. The concept of CRT （critical race theory） provides modern legal debates outlining the usefulness of historical civil rights policies in opinionated climates. This study will examine the role of CRT in relation to affirmative action and desegregation case law. CRT forms the framework for examining the impact of the creation of two MSI law schools in the state of Florida. In conclusion, this study found that minority representation in law schools has improved in Florida as a result of the OFI as well as the addition of two MSI law schools. Black representation, however, continues to lag behind other races, particularly the Hispanic population. This study concluded that the OFI has helped improve minority representation in the legal profession.  相似文献   

Sport,Homelessness, and Capability: Voices from the Street     

Grant Jarvie  Susan Ahrens 《Quest (Human Kinetics)》2019,71(2):239-251

ABSTRACT

To what extent does soccer increase the capability of the homeless and those living on the street? This study addresses this question by focusing on the ways in which the Homeless World Cup and Street Soccer (Scotland) have impacted upon the lives of some individuals. Primary source data obtained from a series of interviews are situated within Sen’s capability approach to social choice theory. The implications of the study contribute to policy by supporting the idea that sport can contribute as a resource of hope through the development of capability that impacts upon life chances and choices. It adds to a growing number of applied studies of sport that have critically used the work of Sen and it advances the way in which this body of work has been utilized in sport and related areas.  相似文献   

Access to postsecondary education through sign language interpreting   总被引：1，自引：0，他引：1  

Marschark M  Sapere P  Convertino C  Seewagen R 《Journal of deaf studies and deaf education》2005,10(1):38-50

Despite the importance of sign language interpreting for many deaf students, there is surprisingly little research concerning its effectiveness in the classroom. The limited research in this area is reviewed, and a new study is presented that included 23 interpreters, 105 deaf students, and 22 hearing students. Students saw two interpreted university-level lectures, each preceded by a test of prior content knowledge and followed by a post-lecture assessment of learning. A variety of demographic and qualitative data also were collected. Variables of primary interest included the effects of a match or mismatch between student interpreting preferences (interpreting vs. transliteration) and the actual mode of interpreting, student-interpreter familiarity, and interpreter experience. Results clarify previous contradictory findings concerning the importance of student interpreting preferences and extend earlier studies indicating that deaf students acquire less than hearing peers from interpreted college-level lectures. Issues relating to access and success in integrated academic settings are discussed as they relate to relations among student characteristics, interpreter characteristics, and educational settings.  相似文献

Recruiting the graduate voice: informing higher education initiatives to underpin an emerging,veterinary paraprofession in Australia     

Patricia Clarke  Joerg Henning  Glen Coleman  Daniel Schull 《Journal of Vocational Education & Training》2019,71(1):126-152

In Australia, the inception of veterinary technology, as a higher education discipline underpinning an emerging, mid-tier paraveterinary field, reflected global trends for more highly educated veterinary paraprofessionals to meet changing societal demands. In this study, veterinary technology graduates were surveyed about their experiences in the workforce and reflections on their education. Seeking feedback on how well a new programme has prepared graduates for the workforce is a useful quality assurance tool. Clinical veterinary practice was the primary employment sector with the majority of respondents in full-time employment. Career advancement, professional recognition and salaries were identified as key career challenges. The important roles of the veterinary and veterinary nursing professions, the university, government and graduates in the development of this mid-tier, veterinary paraprofession were elucidated. Graduates’ feedback on criteria that underpinned ‘work-readiness’ revealed seven key domains: communication skills, research skills, knowledge, critical thinking/problem-solving, employability, practical skills and professionalism. Veterinary nursing skills, work placement, practice management and production animal health were flagged as areas for curricular improvement. This study illuminated facilitators and barriers critical to establishing a mid-tier veterinary paraprofession, bridging the divide between the vocational and higher education sectors in Australia.

The Changing Role of Higher Education in the United States     

K. Patricia Cross 《高等教育研究与发展》1987,6(2):99-108

The role of higher education has changed in the United States. It has become a learning society where egalitarian pressures for equal opportunities led to the expansion of educational services to broader and more representative segments of society. Five propositions illustrate the current pressures for change. (1) Institutions of higher education no longer enjoy a monopoly on the provision of educational services. The learning society has given higher education new competition for the growing adult market. (2) The roles of education providers are increasingly blurred. (3) Higher education no longer has the full‐time commitment of students or of faculty. (4) Lifelong learning has become a lifelong necessity for almost everyone, which demands flexibility and responsiveness to change on the part of higher education. (5) A change is needed in the methods of teaching and learning to accommodate adult learners and to provide for the long‐ range needs of the learning society.  相似文献
