Peer Assessment Learning Sessions (PALS): an innovative feedback technique for large engineering classes     

L. M. O'moore  T. E. Baldock 《European Journal of Engineering Education》2007,32(1):43-55

This paper reports the development of innovative assessment sessions within two core technical courses in Civil Engineering at the University of Queensland. Peer Assessment Learning Sessions (PALS) facilitate a student's peer assessment of a colleague's problem-based learning assignment or tutorial within a ‘traditional’ whole-class setting, under guidance from the lecturer. The assessment is carried out against worked solutions, with a template marking scheme. Following the class, submissions are reviewed by the lecturer and marks moderated if required. In combination, the review and the PALS provide very clear indication where the class or individuals have misconceptions, and where knowledge is below required criteria. This enables the lecturer to provide an accurate synthesis of these points to the class. Students obtain summative feedback, individual formative feedback and whole-class formative feedback within a few days of submission. This significantly improves student's self-reflection and their review of class material. Feedback is very positive and demonstrated here through the presentation of anonymous survey results. PALS address the challenge of providing frequent, efficient and timely assessment for large classes of 100–200+students while simultaneously enabling and providing high quality formative feedback.  相似文献

大学英语写作同级反馈训练模式及其有效性研究     

张艺琼  曾海苹 《湖南科技学院学报》2007,28(8):170-172

同级反馈在过程法写作教学中起着重要作用,但前人的研究表明同级反馈如果没有经过培训则是低效的。为了充分发挥同级反馈的作用,文章提出“错误归类修改-教师评讲-同学互改”的同级反馈训练模式。该反馈训练模式经教学实践证明有效,主要表现为：1．经过培训后进行的同级反馈在质量上得到了较大程度的提高;2．经过同级反馈训练后学生作文的语法错误程下降趋势。  相似文献   

Hybrid ants-like search algorithms for P2P media streaming distribution in ad hoc networks     

ZUO Dong-hong DU Xu YANG Zong-kai 《浙江大学学报(A卷英文版)》2007,8(8):1191-1198

Media streaming delivery in wireless ad hoc networks is challenging due to the stringent resource restrictions,po-tential high loss rate and the decentralized architecture. To support long and high-quality streams,one viable approach is that a media stream is partitioned into segments,and then the segments are replicated in a network and served in a peer-to-peer(P2P) fashion. However,the searching strategy for segments is one key problem with the approach. This paper proposes a hybrid ants-like search algorithm(HASA) for P2P media streaming distribution in ad hoc networks. It takes the advantages of random walks and ants-like algorithms for searching in unstructured P2P networks,such as low transmitting latency,less jitter times,and low unnecessary traffic. We quantify the performance of our scheme in terms of response time,jitter times,and network messages for media streaming distribution. Simulation results showed that it can effectively improve the search efficiency for P2P media streaming distribution in ad hoc networks.  相似文献

The development of student feedback literacy: the influences of teacher feedback on peer feedback     

Ye Han 《Assessment & Evaluation in Higher Education》2020,45(5):680-696

Abstract

Although the concept of student feedback literacy has drawn increasing attention in higher education, empirical research on this matter is still in its infancy. In the area of peer feedback, little research has investigated the role of teacher follow-up feedback on peer feedback in the development of student feedback literacy. To address the research gap, a multiple-case study of three Chinese master’s students enrolled in an academic writing course was conducted, drawing on the students’ drafts with peer feedback, teacher written feedback on that peer feedback, semi-structured interviews, retrospective verbal reports, observation field notes and class documents. Three students’ epistemological and practical knowledge about, attitudes towards, and self-efficacy beliefs in peer feedback were found to improve at different paces and to different degrees. However, considerable individual variations were observed with two high-achieving, highly motivated participants becoming more feedback-literate than their under-achieving, minimally motivated peer. Teacher feedback on peer feedback was found to have distinct impacts on individual students, depending on learner factors including language ability, beliefs and motivation. These findings suggest that teacher feedback on peer feedback, if consistently provided and compatible with learner factors, can scaffold both cognitive and social-affective aspects of student feedback literacy.  相似文献   

Engaging student teachers in meaningful reflective practice   总被引：1，自引：0，他引：1  

Judith Harford  Gerry MacRuairc 《Teaching and Teacher Education》2008

This paper examines the use of peer-videoing in the classroom as a tool to promote reflective practice among student teachers. Twenty pre-service teachers from a variety of subject disciplines participating in a Post-Graduate Diploma in Education programme in an Irish university participated in the study. The practice of encouraging student teachers working in the same school to participate in structured video analysis avoids the impact of external observers whose role is largely evaluative and endorses a collaborative model that promotes dialogue and shared learning. This practice promotes a culture of observation and critical dialogue in a profession which has traditionally been characterised by isolation, while at the same time fostering and validating the voice and experience of the student teacher. Locating the discussion within the framework of the theoretical literature on reflective practice, the purpose of this paper is to contribute to the international debate over best practice in supporting, encouraging and scaffolding reflective practice. It comments on the implications of reflective dialogue for the modernisation of teacher education and offers guidelines on how best to scaffold and promote reflectivity.  相似文献   

入世背景下我国司法审查制度的完善 --基于对法官素质的思考     

彭顺勇  李莎莎 《湖南广播电视大学学报》2005,15(4):71-75

入世首先是政府入世，这早已成为共识，对行政救济中司法审查制度的研究也一度成为热点。但这些研究中大多数只局限于研究司法审查制度本身，而忽视了其最主要的实施主体：法官。提高法官素质是完善我国司法审查制度的逻辑必然，忽视了人的因素，再完美的制度设计也只能是空中楼阁。本文将探讨入世背景下完善我国司法审查制度对法官素质的要求，以及针对这些要求，有效提高法官素质的途径。  相似文献   

The Review of Vocational Qualifications, 1985 to 1986: An Analysis of its Role in the Development of Competence-based Vocational Qualifications in England and Wales     

George Hargraves 《British Journal of Educational Studies》2000,48(3):285-308

A significant historical role in the development of competence-based vocational qualifications in England and Wales is customarily ascribed to the 1985 to 1986 Review of Vocational Qualifications (RVQ), the body which invented the National Vocational Qualification (NVQ). This paper analyses the RVQ's internal debates. The paper demonstrates that the RVQ proposed only the general principles of a structure and an administration for a reformed vocational qualifications system. The RVQ did not address in detail either the definition of occupational competence or the curriculum and assessment models to be embodied in the NVQ. In the light of this analysis, the paper re-evaluates the role of the RVQ in the development of competence-based vocational qualifications, and suggests some potentially fruitful areas for future research.  相似文献
