A review of ‘psychology and the study of education: critical perspectives on developing theories’     

Christopher P. Dwyer 《Irish Educational Studies》2019,38(2):213-217

This review examines Psychology and the Study of Education: Critical Perspectives on Developing Theories, a collection of academic articles edited by Cathal Ó Siochrú. The collection comprehensively considers wide-ranging topics pertinent to the psychology of education, with a target audience of educators and students wishing to learn more about psychology. The review evaluates the collection as an integrated work of entries and analyses each component chapter; recognising the success of the collection with respect to its aim of challenging readers to critically reflect upon and consider the value of psychology in both understanding and influencing education. The book transcends the common formula of academic article collections in this area by being presented in a somewhat conversational manner, making it both interesting and accessible. The book is recommended for anyone interested in the psychology of education and for anyone who values the advancement of learning and teaching.  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   

校阅在CAT与FIT中对受测者行为表现与状态焦虑水平的影响     

陈燕  胡洁 《考试研究》2007,(1)

校阅(review)对CAT中受测者心理影响的研究有利于CAT的推广应用。J.Oleat等研究者在CAT(computerizedadaptivetest,计算机自适应性测验)与FIT(fixed-itemtest,固定项目测验)中,将校阅(review)对受测者行为表现与状态焦虑水平的影响作了比较研究。实验结果表明,在允许校阅的环境中,受测者正确反应与被估计的能力水平显著增加,并且状态焦虑水平下降。本文对J.Oleat等研究者的主要研究成果进行了详细的评述,并进一步探讨了在CAT中增设校阅(review)环境的重要性和可能性。  相似文献

五十年来青海汉语方言研究述评     

张成材 《青海师范大学学报(哲学社会科学版)》2005,(3):110-113

本全面系统地评述了五十年来青海汉语方言研究的进展情况。认为五十年来青海汉语方言研究具有从无到有的开创性质，参加人数不算少、论数量也不算少、内容涉及面也不算窄，但比起兄弟省市来看，相当滞后。目前存在一些亟待解决的问题，诸如：培养后继队伍的问题；缺乏方言研究的组织领导和专门研究机构问题；如何将研究内容引向纵深的问题等等。  相似文献   

An empirical review of anonymity effects in peer assessment,peer feedback,peer review,peer evaluation and peer grading     

Ernesto Panadero  Maryam Alqassab 《Assessment & Evaluation in Higher Education》2019,44(8):1253-1278

Abstract

Peer assessment has proven to have positive learning outcomes. Importantly, peer assessment is a social process and some claim that the use of anonymity might have advantages. However, the findings have not always been in the same direction. Our aims were: (a) to review the effects of using anonymity in peer assessment on performance, peer feedback content, peer grading accuracy, social effects and students’ perspective on peer assessment; and (b) to investigate the effects of four moderating variables (educational level, peer grading, assessment aids, direction of anonymity) in relation to anonymity. A literature search was conducted including five different terms related to peer assessment (e.g., peer feedback) and anonymity. Fourteen studies that used a control group or a within group design were found. The narrative review revealed that anonymous peer assessment seems to provide advantages for students’ perceptions about the learning value of peer assessment, delivering more critical peer feedback, increased self-perceived social effects, a slight tendency for more performance, especially in higher education and with less peer assessment aids. Some conclusions are that: (a) when implementing anonymity in peer assessment the instructional context and goals need to be considered, (b) existent empirical research is still limited, and (c) future research should employ stronger and more complex research designs.  相似文献

Paired peer learning through engineering education outreach     

Laura Fogg-Rogers  Fay Lewis  Juliet Edmonds 《European Journal of Engineering Education》2017,42(1):75-90

ABSTRACT

Undergraduate education incorporating active learning and vicarious experience through education outreach presents a critical opportunity to influence future engineering teaching and practice capabilities. Engineering education outreach activities have been shown to have multiple benefits; increasing interest and engagement with science and engineering for school children, providing teachers with expert contributions to engineering subject knowledge, and developing professional generic skills for engineers such as communication and teamwork. This pilot intervention paired 10 pre-service teachers and 11 student engineers to enact engineering outreach in primary schools, reaching 269 children. A longitudinal mixed methods design was employed to measure change in attitudes and Education Outreach Self-Efficacy in student engineers; alongside attitudes, Teaching Engineering Self-Efficacy and Engineering Subject Knowledge Confidence in pre-service teachers. Highly significant improvements were noted in the pre-service teachers’ confidence and self-efficacy, while both the teachers and engineers qualitatively described benefits arising from the paired peer mentor model.  相似文献   

Peer facilitated writing groups: a programmatic approach to doctoral student writing     

Vijay Kumar  Claire Aitchison 《Teaching in Higher Education》2018,23(3):360-373

Very few empirical studies have investigated programmes in which doctoral students act as peer facilitators in faculty writing groups. We report on the development of a centrally delivered doctoral student writing programme in which twenty student participants were mentored and provided with the resources to initiate their own faculty-based doctoral writing groups. ‘Legitimate peripheral participation’ was used as a conceptual lens to interpret the data collected during the establishment and evaluation of the programme. All student participants in the preparatory training course, which was developed in consultation with postgraduate students and research supervisors, went on to become doctoral writing peer facilitators of peer writing groups. Insights from seven of these showed how a well-structured and supportive programme harnessed the benefits of peer learning by bringing personal rewards to participants and building institutional capacity around doctoral research writing literacies.  相似文献
