A comparison of modeling modalities in the observational learning of an externally paced skill.     

D L Weeks 《Research quarterly for exercise and sport》1992,63(4):373-380

This study contrasted prepractice modeling with either the perceptual component (perceptual modeling) or the motor component (movement pattern) of a coincident-timing task to determine whether experiencing the modalities singly or in combination enhanced timing performance on initiation of active practice. The motor component was a 60-cm right-to-left arm movement coincident with the illumination of lights on a Bassin timer runway to displace a barrier as the final runway light was illuminated. Four groups were compared (n = 12 per group). A perceptual modeling group passively viewed stimulus runway lights prior to attempting the task. A motoric modeling group viewed a videotape prior to practice of a model performing the motor component of the skill with zero timing error. A perceptual modeling plus motoric modeling group experienced both modeling modalities prior to performance. Finally, a no modeling group simply initiated practice on the task without modeling. Results indicated that the groups experiencing perceptual modeling initiated practice with significantly less average timing error and variability. Thus, perceptual modeling appeared to be at least as important as motoric modeling as a source of prepractice information to make available to a learner to optimize coincident-timing skill acquisition.  相似文献   

Teachers’ emotions in the reconstruction of professional self-understanding     

Alexa Darby 《Teaching and Teacher Education》2008

This research study explores teachers’ specific emotions and the reconstruction of teachers’ professional self-understanding during a comprehensive school reform initiative. Through interviews and archival material, this study seeks to examine teachers’ specific emotions during critical incidents that occurred during the period of reform and to explore the reconstruction of their professional self-understanding. The findings illustrate that the teachers experienced fear and intimidation when their professional self-understandings were challenged. However, with the support of a literacy coach and university faculty they reconstructed these self-understandings, leading to improvements in student achievement and their own instructional practices. These positive changes led to emotions of pride and excitement. The study provides recommendations for state and local school administrators and highlights implications for future research.  相似文献   

Changing Schools of Education Through Grassroots Faculty-led Change     

Jill Alexa Perry 《Innovative Higher Education》2014,39(2):155-168

In this article I report on the application of the lens of Rogers’ (1995) change agent roles and Kezar and Lester’s (2011) adaptation of tempered radicals in order to understand the leadership roles assumed by three individual faculty members located at three distinct schools of education. These faculty leaders utilized the concepts and principles of the Carnegie Project on the Education Doctorate (CPED) to lead redesigns of their Ed.D. programs. Qualitative data were gathered during a larger study on institutional change. Findings contribute to understanding grassroots leadership and how it works in collaboration with top-down authorities.  相似文献   

Proving the proverbial gadfly: situating the historical and racial context of Southern medical works by Mary Louise Marshall     

Aidy Weeks 《Journal of the Medical Library Association》2021,109(4):528

Health sciences librarianship has historically benefited from avoiding critical conversations around the role of race in the profession, reflected through a select few number of articles on the topic. The purpose of this study was to add to this body of literature and apply a critical librarianship framework on the early scholarly record of health sciences librarianship and the legacy of integration within the Medical Library Association (MLA). Three Southern medical works and the integration views of Mary Louise Marshall, the longest-serving president of MLA from 1941 to 1946, were thematically and textually analyzed to redress the profession''s long-standing legacy with Whiteness and Black, Indigenous, and People of Color (BIPOC) representation. In reframing the historic past of MLA both through Marshall''s works and her views, the goal is to acknowledge ways in which the profession has impeded progress and present steps to remedy appropriate outreach for the future.  相似文献
