‘I like the sound of that’ – an evaluation of providing audio feedback via the virtual learning environment for summative assessment

This study aims to ascertain student and staff attitudes to and perceptions of audio feedback made available via the virtual learning environment (VLE) for summative assessment. Consistent with action research and reflective practice, this study identifies best practice, highlighting issues in relation to implementation with the intention of redesigning activities in the light of the findings. It utilises four case studies where audio feedback was provided to students using the Wimba voice authoring tool within Blackboard Learn+ for various types of summative assessment. The intention was to identify how and in what context audio feedback via the VLE is effective and why. The research was undertaken via a combination of techniques, including a student survey and staff reflective logs. The findings indicate that students liked the convenience, effectiveness, flexibility and personalised nature of this feedback, but raised concerns with some aspects of the technology. This paper also makes practical recommendations for the use of the feedback mechanism, focusing on the most effective use of the digital medium, and highlights directions for future research.     

关联理论下的翻译行为与英语阅读

英语阅读的困境在于阅读者缺乏相关的异域文本信息。翻译行为在阅读者母语认知框架内引入新信息,扩展阅读者的认知语境以帮助阅读者以较小努力建立与英语文本的最佳关联,从而达到阅读交际的目的。阅读中的直接翻译行为强调对文本交流线索的体现,是引导阅读者达到更准确阅读的重要策略。由于对相关性的强调,对异域隐喻的翻译行为将进一步减少认知努力,使阅读理解更加顺利。     

电视对彝族村落社会流动的影响——基于布里莫村的民族志调研

运用参与观察、问卷调查、个人访谈、焦点组访谈等研究方法,对彝族村落的媒介消费状况,电视对村民社会流动的影响等问题进行调研。研究发现,彝族村落的媒介消费呈现出"非立体化"和"单一化"的态势;电视对其社会流动产生了重要影响,但这种影响是"隐性"的,具体表现为:在水平流动中,对村民由农村流向城市具有诱惑作用;在垂直流动和代际流动中,对村民上升流动的决策形成产生了潜移默化的影响。

Exploring the moderating role of well-being on the adaptive link between self-assessment practices and learning achievement

Self-assessment practices can positively impact student learning and achievement. However, less is known about psychological moderators that can influence the impact that self-assessment practice may have on achievement. Integrating the dual processing self-regulation model and the self-assessment cycle framework, this study examined the role of students’ positive well-being in the link between self-assessment practices and domain-specific achievement scores. Hierarchical multiple regression analyses using data from 765 secondary school students revealed that self-assessment practices positively predicted achievement scores. Results also showed that positive well-being moderated the relationship between seeking internal feedback and self-reflection and achievement scores, in that the positive link between such self-assessment practices and achievement was stronger for students who had low or moderate well-being. These findings reinforce the impact of self-assessment on learning and add to the ecological validity of the dual processing self-regulation model. The discussion focuses on how these findings contribute to our understanding of how well-being could influence the adaptive role of internal and cognitive self-assessment practices in student learning. Limitations and future research directions are also discussed.     

The bilateral benefits of providing and receiving peer feedback in academic writing across varying L2 proficiency

Although the effectiveness of peer review has been examined, few have tested the joint benefits of providing and receiving feedback features and quality in L2 contexts. The present study investigated variation in key features and quality of feedback provided and received by high and low L2 proficiency students and its benefits on revision in the authentic setting of students experiencing both roles of providing and receiving peer feedback in English academic writing. Analyses on two drafts from 50 students, 1356 idea units of anonymous implementable peer feedback and back-evaluation ratings revealed that the combined effect of providing and receiving feedback on revision was prominent for all students. But the bilateral benefits of providing and receiving feedback features were more significant for high proficiency students, while providing feedback features and quality benefited low proficiency students more. The study implies that students need more bilateral training with both providing and receiving feedback.

Improving zero-shot retrieval using dense external expansion

Pseudo-relevance feedback (PRF) is a classical technique to improve search engine retrieval effectiveness, by closing the vocabulary gap between users’ query formulations and the relevant documents. While PRF is typically applied on the same target corpus as the final retrieval, in the past, external expansion techniques have sometimes been applied to obtain a high-quality pseudo-relevant feedback set using the external corpus. However, such external expansion approaches have only been studied for sparse (BoW) retrieval methods, and its effectiveness for recent dense retrieval methods remains under-investigated. Indeed, dense retrieval approaches such as ANCE and ColBERT, which conduct similarity search based on encoded contextualised query and document embeddings, are of increasing importance. Moreover, pseudo-relevance feedback mechanisms have been proposed to further enhance dense retrieval effectiveness. In particular, in this work, we examine the application of dense external expansion to improve zero-shot retrieval effectiveness, i.e. evaluation on corpora without further training. Zero-shot retrieval experiments with six datasets, including two TREC datasets and four BEIR datasets, when applying the MSMARCO passage collection as external corpus, indicate that obtaining external feedback documents using ColBERT can significantly improve NDCG@10 for the sparse retrieval (by upto 28%) and the dense retrieval (by upto 12%). In addition, using ANCE on the external corpus brings upto 30% NDCG@10 improvements for the sparse retrieval and upto 29% for the dense retrieval.
