Augmenting performance feedback does not affect 4 km cycling time-trials in the heat     

Mark Waldron  Vincent Villerius  Aron Murphy 《Journal of sports sciences》2015,33(8):786-794

We compared the effects of (1) accurate and (2) surreptitiously augmented performance feedback on power output and physiological responses to a 4000 m time-trial in the heat. Nine cyclists completed a baseline (BaseL) 4000 m time-trial in ambient temperatures of 30°C, followed by two further 4000 m time-trials at the same temperature, randomly assigning the participants to an accurate (ACC; accurate feedback of baseline) or deceived (DEC; 2% increase above baseline) feedback group. The total power output (PO) and aerobic (P_aer) and anaerobic (P_an) contributions were determined at 0.4 km stages during the time-trials, alongside measurements of rectal (T_rec) and skin (T_skin) temperatures. There were no differences (P > 0.05) in any of the variables between BaseL, ACC and DEC, despite increases (P < 0.05) in T_rec and T_skin. Typical pacing profiles were demonstrated; however, there was no interaction (P > 0.05) between feedback condition and time-trial stage. Providing surreptitiously augmented performance feedback to well-trained cyclists did not alter their performance or physiological responses to a 4000 m time-trial in a hot environment. The assumed influence of augmented performance feedback was nullified in the heat, perhaps reflecting a central down-regulation of exercise intensity in response to an increased body temperature.  相似文献   

“Think With Me:” David Carr's Enduring Invitation     

Beverly Sheppard  Marsha Semmel  Carol Bossert 《Curator: The Museum Journal》2016,59(2):113-119

David Wildon Carr (1945–2016) was recognized in the international cultural community as a scholar and instigator whose critical thinking challenged museum practitioners to reflect on the purpose and responsibility of their work. In his recent papers and lectures, he argued that those discussing museum experiences are late to enter into a dialogue already in progress—a dialogue which carefully considers the whole person in a community, and wherein thinking with a museum is an enterprise embedded in the learner's experience. This forum, written by three museum professionals in response to his recent untimely death, is intended to capture personal impressions of Carr's contribution to the continuing work of museums. Each author quotes from Carr's writings, since his words have such enduring strength—a strength that will continue to resonate long into the future. Each also offers readers some personal background on his work as a teacher.  相似文献

A Comparison of Teacher Effectiveness Measures Calculated Using Three Multilevel Models for Raters Effects     

Daniel L. Murphy  S. Natasha Beretvas 《教育实用测度》2015,28(3):219-236

This study examines the use of cross-classified random effects models (CCrem) and cross-classified multiple membership random effects models (CCMMrem) to model rater bias and estimate teacher effectiveness. Effect estimates are compared using CTT versus item response theory (IRT) scaling methods and three models (i.e., conventional multilevel model, CCrem, CCMMrem). Results indicate that ignoring rater bias can lead to teachers being misclassified within an evaluation system. The best estimates of teacher effectiveness are produced using CCrems regardless of scaling method. Use of CCMMrems to model rater bias cannot be recommended based on the results of this study; combining the use of CCMMrems with an IRT scaling method produced especially unstable results.  相似文献   

Developing Critical Social Justice Literacy in an Online Seminar     

Elizabeth Bondy  Amy S. Murphy  Rachel Wolkenhauer  Desi Krell 《Equity & Excellence in Education》2015,48(2):227-248

The purpose of this article is to report on an effort to cultivate a critical social justice perspective and critical social justice praxis among educators enrolled in an online graduate program. Although the entire program was organized around themes of equity, collaboration, and leadership, this study focused on educators’ perspectives of the purposes, pedagogy, and outcomes of one course, Critical Pedagogy. Fourteen of the 19 students enrolled in the online course participated in one of six online focus groups following the conclusion of the course. Using constructivist grounded theory methods, the researchers identified the different ways in which students responded to the course, what they learned, and how they enacted their learning as well as the features of the course that the students believed contributed to their learning and practice. The study provides insight into features of online pedagogy that appear to facilitate transformative learning. It further provides insight into the kinds of content and assignments that may promote critical social justice praxis among educators.  相似文献   

Using Vygotsky’s zone of proximal development to propose and test an explanatory model for conceptualising coteaching in pre-service science teacher education     

Colette Murphy  Kathryn Scantlebury  Catherine Milne 《Asia-Pacific Journal of Teacher Education》2015,43(4):281-295

Coteaching offers a model for the school-placement element of pre-service science teacher education, based on its demonstrated positive impacts on lessening classroom anxiety, supporting inquiry-based science teaching, improving students’ attitudes, and addressing diversity effectively in science classrooms. Coteaching between pre-service and in-service teachers is used to lessen the gap between theory and practice, to develop reflective practice and to develop pedagogical content knowledge. Explanatory frameworks have been proposed for coteaching, and we suggest that Vygotsky’s zone of proximal development helps to propose a more nuanced developmental and learning explanatory framework which provides pedagogical structures for implementation and highlights the importance of the social environment for learning. In providing structure and tools for effective implementation of coteaching, our model addresses three core elements of coteaching: coplanning, copractice, and coevaluation. The model was piloted in relation to pre-service teachers’ development in reflective practice and reducing the gap between theory and classroom practice.  相似文献   

Exploring the impact of coteaching on pre-service music teachers     

Marita Kerin  Colette Murphy 《Asia-Pacific Journal of Teacher Education》2015,43(4):309-323

This study describes and analyses how coteaching affected undergraduate music education preservice teachers (PSTs). During an 8-week school placement, coteaching was used as a means of creating a reciprocal professional learning arrangement involving PSTs and primary school teachers. The theoretical framework draws on the Russian concept of obuchenie, which is a dialectical process of mutual adaptation between student and teacher. Music education PST participated as subject expert/pedagogy novice, while generalist classroom teacher occupied the role of pedagogy expert/music novice. Findings relate to the acquisition of four aspects of teacher professional agency, subject or content knowledge, pedagogical knowledge, curricular knowledge, and pedagogical content knowledge. A thematic analysis was undertaken using data from interviews, PST reflective journals, observations, lesson plans, and researcher field-notes. In comparison with the traditional school placement, there was a radical improvement in the development of professional agency amongst the coteaching cohort.  相似文献   

An Australian Proposal for Doing Critical Literacy Assessment: The Case of Writing     

Claire Wyatt-Smith  Judy Murphy 《English in Education》2002,36(3):4-19

In this article we present current thinking and practices in Queens land, Australia, about how to do critical literacy assessment in the English classroom. In taking this focus, we propose and discuss a framework that brings together interest in text analysis and social practices. Then, we apply the framework showing how it can be used to generate writing tasks and assessment criteria that are consistent with critical pedagogy. Finally, the challenges of moving to a socially critical, discourse‐oriented approach to assessment are considered.  相似文献
