Learning to rank query suggestions for adhoc and diversity search     

Rodrygo L. T. Santos  Craig Macdonald  Iadh Ounis 《Information Retrieval》2013,16(4):429-451

Query suggestions have become pervasive in modern web search, as a mechanism to guide users towards a better representation of their information need. In this article, we propose a ranking approach for producing effective query suggestions. In particular, we devise a structured representation of candidate suggestions mined from a query log that leverages evidence from other queries with a common session or a common click. This enriched representation not only helps overcome data sparsity for long-tail queries, but also leads to multiple ranking criteria, which we integrate as features for learning to rank query suggestions. To validate our approach, we build upon existing efforts for web search evaluation and propose a novel framework for the quantitative assessment of query suggestion effectiveness. Thorough experiments using publicly available data from the TREC Web track show that our approach provides effective suggestions for adhoc and diversity search.  相似文献   

Girls and physics: teaching and learning strategies tested by classroom interventions in grade 11     

Peter Labudde  Walter Herzog  Markus P. Neuenschwander  Enrico Violi  Charlotte Gerber 《International Journal of Science Education》2013,35(2):143-157

In this quasi-experimental study various strategies are developed and empirically tested for an approach to physics instruction that should improve girls' and boys' attitudes toward and achievements in physics. Strategies include opportunities to integrate different pre-existing knowledge and the variation of teaching methods to enhance co-operation and communication in the classroom. The core of this study is an intervention in 31 classes of public schools in Switzerland. The intervention, one unit in optics and one in motion (velocity/acceleration), includes the first 40 lessons of the first physics course that all students have to attend at the upper secondary level. Data sources are various student and teacher questionnaires, tests and semi-structured interviews with teachers. Results of the entrance and final survey are presented. The focus will be on some of the applied strategies. Implications for the teaching and learning of physics and for teacher education are discussed.  相似文献   

Cultural interpretations of the visual meaning of icons and images used in North American web design     

Eliot Knight  Charlotte N. Gunawardena  Cengiz Hakan Aydin 《Educational Media International》2013,50(1):17-35

This study examines cross‐cultural interpretations of icons and images drawn from US academic websites. Participants from Morocco, Sri Lanka, Turkey, and the USA responded to an online questionnaire containing 18 icons and images representing online functions and information types common on US academic websites. Participants supplied meanings for icons and images and selected a preferred image to represent each of four specific online functions. From three images of professors, participants chose one with whom they would prefer to study. Data were collected at the University of New Mexico, USA; in Internet cafes in the Middle Atlas region and at Al‐Akhawayn University, Morocco; the Open University of Sri Lanka in Nawala, Nugegoda; and at Anadolu University, Turkey. A qualitative analysis examines participants' perspectives and preferences for specific representations and identifies cultural themes in relation to Hofstede's dimensions. Implications for the design of images for cross‐cultural users are discussed.

L'interprétation culturelle de la signification visuelle des icônes et images utilisées dans la conception de sites Web en Amérique du Nord

La présente étude porte sur les interprétations transculturelles des icônes et des images extraites de sites universitaires américains. Des participants venus du Maroc,du Sri Lanka, de Turquie et des Etats Unis, ont répondu à un questionnaire en ligne contenant 18 icônes et images représentant des fonctions en ligne et des modes d'information que l'on trouve couramment sur les sites universitaires américains. Ces participants ont attribué des significations aux icônes et images et sélectionné l'image qu'ils (elles) préféraient pour représenter chacune des quatre fonctions en ligne proposées. A partir de trois images de professeurs,les participants en ont choisi une, celle avec qui ils (elles) préféreraient étudier. Une étude quantitative examine les perspectives des participants et leurs préférences pour une représentation donnée et elle identifie les thèmes culturels par rapport aux dimensions de Hofstede. On étudie les conséquences que cela peut avoir pour la conception d'images destinées à des utilisateurs interculturels.

Kulturelle Interpretationen der visuellen Bedeutung der Symbole und Bilder, die in Nordamerika Web‐Design benutzt werden

Diese Studie untersucht cross‐kulturelle Interpretationen von Symbolen und Bildern, die in akademischen US‐Websites benutzt werden. Teilnehmer aus Marokko, Sri Lanka, der Türkei und den USA bearbeiteten einen Online‐Fragebogen mit 18 Ikonen und Bildern, die Online‐Funktionen und – Informationen auf akademischen US‐Websites gemeinsamen sind. Die Teilnehmer benannten angenommene Bedeutungen der Symbole und Bilder und wählten ein bevorzugtes Bild für jede der vier spezifischen Online‐Funktionen aus. Aus drei Bildern von Professoren wählten die Teilnehmer eines aus, das denjenigen zeigen sollte, mit dem sie es vorziehen würden zu studieren. Eine qualitative Analyse untersucht Perspektiven und Präferenzen der Teilnehmer für bestimmte Vertretungen und Identitäten kultureller Themen in Bezug auf die von Hofstede aufgestellten Dimensionen. Auswirkungen auf die Gestaltung von Bildern für cross‐kulturelle Nutzer werden diskutiert.

La interpretación cultural del significado visual de iconos y imagenes utilizados en el diseño de sitios Web en América del Norte

Este artículo examina las interpretaciones transculturales de iconos y imágenes procedentes de sitios académicos de los Estados Unidos. Participantes de Marruecos, Sri Lanka, Turquía y los EUA respondierón a un cuestionario en línea conteniendo 18 iconos y imágenes que representan funciones en línea y tipos de información que se encuentran frecuentemente en los sitios académicos de los EUA. Los participantes propusieron significados para los iconos y imágenes y seleccionarón la imágen que les parecía más idónea para representar cada una de cuatros funciones en línea específicas. Entre tres imágenes de profesores, los participantes seleccionarón una, la de la persona con quien les gustaría estudiar. Un análisis cualitativo examina las perspectivas y preferencias de los participantes para tal o tal representación específica y al mismo tiempo se analiza temas culturales en relación con las dimensiones de Hofstede. Se analizan también las consecuencias que esto conlleva para el diseño de imágenes destinadas a usuarios transculturales.  相似文献   

Internet in the Classroom: Effects on Reading Comprehension,Motivation and Metacognitive Awareness     

Carina Weinmann  Charlotte Löb  Tamara Mattheiß 《Educational Media International》2013,50(3):149-161

This study examined the potential of entertainment-education (E-E) for promoting engagement with a science issue. It was assumed that certain entertaining features of a media experience increase viewers’ perceived knowledge about an issue. Drawing on different theoretical models of E-E and on persuasive effects of narrative media messages, three hypotheses and one research question were assessed in a survey among 103 participants, who were shown a movie about genetic engineering beforehand. Results suggested that the higher viewers’ transportation, identification, and enjoyment were, the more they actually felt informed. Viewers’ degree of transportation, though, revealed to be sufficient to explain their perceived knowledge.  相似文献

Promoting assessment efficacy through an integrated system for online clinical assessment of practical skills     

Peter J. Hay  Craig Engstrom  Anita Green  Peter Friis  Sue Dickens  Doune Macdonald 《Assessment & Evaluation in Higher Education》2013,38(5):520-535

This paper presents evaluation outcomes from an externally funded research project involving the online clinical assessment of practical skills (eCAPS) using web-based video technologies within a university medical programme. eCAPS was implemented to trial this web-based approach for promoting the efficacy of practical skills assessment in knee joint examinations for a pre-clinical cohort of second year medical students. eCAPS involves a progressive organisation of online video experiences and task expectations for formative and summative assessments of selected competencies. Data are presented from semi-structured interviews with the medical students (N?=?40). eCAPS successfully supported students’ skill development in knee joint examinations on fellow students and allowed remote assessment of candidates’ performances by clinicians experienced in musculoskeletal examinations. An ‘indicative standard’ paradigm, involving formative assessment of one randomly selected performance from the submission of all students’ responses within a small group, offered an efficient and efficacious avenue for providing consolidated feedback to students and promoted desirable learning behaviours. Overall, there was evidence of reciprocal learning benefits to the ‘blending’ of an online learning and assessment approach with an existing face-to-face environment. The medical students were able to successfully engage online with high quality and consistent practical skill-based materials in a flexible, independent and individual manner.  相似文献   

Exploiting Online Interactivity to Enhance Assignment Development and Feedback in Distance Education     

Janet Macdonald 《Open Learning》2013,28(2):179-189

Networking provides the means to deliver enhancements to assignment development and feedback which have not previously been possible for ODL courses. This paper describes the experimental introduction and evaluation of network delivered model answers and peer review as additional formative feedback on assessment. The enhancements assisted students in attuning themselves to the writing demands of the course, and there may be particular times in a course when they are most of value. Use of a network allowed for delivery within a controlled time frame, whilst providing an interactive environment for debate on alternative perspectives.  相似文献   

Coparenting Among Lesbian,Gay, and Heterosexual Couples: Associations With Adopted Children's Outcomes     

Rachel H. Farr  Charlotte J. Patterson 《Child development》2013,84(4):1226-1240

Coparenting is associated with child behavior in families with heterosexual parents, but less is known about coparenting among lesbian‐ and gay‐parent families. Associations were studied among self‐reported divisions of labor, coparenting observations, and child adjustment (M_age = 3 years) among 104 adoptive families headed by lesbian, gay, or heterosexual couples. Lesbian and gay couples reported sharing child care, whereas heterosexual couples reported specialization (i.e., mothers did more child care than fathers). Observations confirmed this pattern—lesbian and gay parents participated more equally than heterosexual parents during family interaction. Lesbian couples showed the most supportive and least undermining behavior, whereas gay couples showed the least supportive behavior, and heterosexual couples the most undermining behavior. Overall, supportive coparenting was associated with better child adjustment.  相似文献
