Anonymous personalization in collaborative web search   总被引：2，自引：0，他引：2  

Barry Smyth  Evelyn Balfe 《Information Retrieval》2006,9(2):165-190

We present an innovative approach to Web search, called collaborative search, that seeks to cope with the type of vague queries that are commonplace in Web search. We do this by leveraging the search behaviour of previous searchers to personalize future result-lists according to the implied preferences of a community of like-minded individuals. This technique is implemented in the I-SPY meta-search engine and we present the results of a live-user trial which indicates that I-SPY can offer improved search performance when compared to a benchmark search engine, across a variety of performance metrics. In addition, I-SPY achieves its level of personalization while preserving the anonymity of individual users, and we argue that this offers unique privacy benefits compared to alternative approaches to personalization.  相似文献   

OER evaluation as a means of teaching information literacy in individual and small group settings     

Sarah Evelyn  John Kromer 《The Reference Librarian》2018,59(1):1-9

ABSTRACT

Open education resources represent a great opportunity to reduce textbook costs, but many of them have not been evaluated for quality. Librarians and former students in an introduction to engineering course collected and evaluated open education resources to supplement the course textbook in future semesters. Both searching for and evaluating these resources created opportunities for the librarians to evaluate information literacy skills of these students and to provide instruction to improve these skills.  相似文献

“I learn for a job promotion!”: the role of outcome-focused career goals in motivating distance learners to learn     

Clarence Ng 《Distance Education》2018,39(3):390-410

Outcome-focused career goals are concerned about studying for tangible career benefits. To what extent do these goals motivate distance learners to learn? Using a mixed-method design, Study 1 found that career-focused learners, when compared with noncareer-focused counterparts, had a propensity to endorse outcome-focused career goals, use surface strategies, value their learning, and achieve better course results. Interview findings showed that career-focused learners used a strategic approach to ensure the timely completion of tasks and examination preparation. Study 2 located two groups of career-focused learners (autonomous and controlled) who endorsed outcome-focused career goals, alongside a noncareer-focused group. MANOVA analyses found that autonomous and noncareer-focused learners had engaged learning patterns. Although controlled learners were less engaged in learning, they achieved better results. It was concluded that outcome-focused career goals are significant sources of motivation for distance learners, despite being extrinsic to learning.  相似文献   

Interactive Effects Between Maternal Parenting and Negative Emotionality on Social Functioning Among Very Young Chinese Children     

Lixin Ren  Ning Zhou  Mei Lee Ng 《Early education and development》2017,28(1):21-40

Research Findings: This study examined how child negative emotionality interacted with mothers’ self-reported parenting in predicting different aspects of social functioning among very young Chinese children. A total of 109 Chinese nursery children in Hong Kong participated with their parents. Maternal supportive and aversive parenting practices were reported by mothers, and child negative emotionality and social functioning were reported by both mothers and fathers. The results revealed interaction effects between child negative emotionality and mothers’ self-reported parenting on children’s internalizing problems, externalizing problems, and social-emotional skill deficiency. Specifically, children with high negative emotionality were more susceptible to the negative effects of aversive parenting (i.e., showing more internalizing and externalizing problems when exposed to aversive parenting) than their peers with low negative emotionality. Negative emotionality also placed young children at risk for social-emotional skill deficiency, especially when they received less support from their mothers compared to their peers. Practice or Policy: Special attention should be paid to the social functioning of Chinese children with higher levels of negative emotionality, because these children are more vulnerable to poor-quality parenting at a very young age.  相似文献   

Teachers’ professional selves and motivation for continuous professional learning amid education reforms     

Clarence Ng 《Asia-Pacific Journal of Teacher Education》2019,47(2):118-136

Promoting in-service teachers’ continuous professional learning is indispensable to educational reforms that demand knowledge acquisition and practice innovation. Addressing this issue, this mixed-method study examined the relationship between teachers’ professional selves and continuous professional learning. Two hundred and nighty-one practicing teachers completed a questionnaire that assessed their current and future professional selves, learning motives, strategy use, self-efficacy, control beliefs, learning interests and intentions. Cluster analyses found that strongly-committed teachers who held strong professional selves had the most engaged patterns of learning followed by teachers who had moderate and weak levels of professional selves. Study two was a follow-up interview study with eight selected teachers who held contrasting professional selves. Strongly-committed teachers discussed their hoped-for selves while weakly-committed teachers expressed concerns about heavy workload and the selves that they feared. These two groups of interviewees differed in the strategies they employed to complete course assignments.  相似文献   

Innovation and Enterprise in Singapore Schools     

Ng Pak Tee 《Educational Research for Policy and Practice》2004,3(3):183-198

Schools in Singapore are now tasked to develop the spirit of innovation and enterprise in their students. This is in line with the national vision of ‘Thinking Schools, Learning Nation’. This policy initiative, which began in 2004, is set to change the fundamental nature of education in Singapore. This article discusses the innovation and enterprise (I&E) initiative, its major implications for schools in Singapore and the areas still to be addressed in the implementation of the policy. In particular, the article discusses the issues of teachers and school leaders as role models of I&E, I&E as an organic part of school business, the influence of the wider societal culture and values system, and the measurement of success of I&E. The challenge for schools is to go beyond the form of the initiative to bring real substantial and sustainable change through this movement.  相似文献   

Alternative models of learning disabilities identification: considerations and initial conclusions     

Johnson E  Mellard DF  Byrd SE 《Journal of learning disabilities》2005,38(6):569-572

The final session of the National Research Center on Learning Disabilities (NRCLD) Responsiveness-to-Intervention (RTI) Symposium, "What are alternative models to LD identification other than RTI?" included four papers that discussed concerns over the exclusive reliance on an RTI approach to learning disability identification, considerations for analyzing proposed LD identification models, and various alternatives to LD identification. The work of the participating panelists is summarized in this discussant paper, and next steps for the NRCLD in light of these presentations are suggested.  相似文献   

网络教学平台使用的师资培动——香港理工大学的经验     

吴廷坚 《远程教育杂志》2007,12(4):4-7

面授和网上教学有机结合的整合式教学越来越成为高校教育和培训的主要模式。本文旨在介绍和分析香港理工大学教学发展中心（简称EDC）如何通过网上教学平台的功能,与面授教学结合起来,发挥面授教学和网上教学的各自优势,使教师培训更加有效。EDC的实践表明,在大学教师培训课程中,发挥网上教学的优势,能帮助学员弥补由于有限的面授教学产生的师生之间、学员和学员之间互动的不足。在网上学习中,通过互相的学习观摩和观念碰撞,能激发学员的学习兴趣,有效地促进学员之间进行探究性学习,同时,这种集体学习的方法,能促进在职教师之间的友好交往和学术交流。  相似文献
