With greater access to computational resources, people use search to address many everyday challenges in their lives, including solving technology problems. Although there are now many useful ‘how-to’ resources online (especially videos on YouTube), it can still be difficult to identify, understand, and resolve certain kinds of technical problem. While research tasks have been studied for many years and we know the tactics people use, we know far less about searchers’ tactics for how-to technical tasks that involve actually being able to apply found information to resolve a problem. Crucial to our study was developing and studying a highly realistic, how-to technical task, for which there was no single guidance resource: making a phone safe for a child. After providing 39 participants with an actual phone to fix, and a search engine to perform the task, we analysed their search tactics using retrospective cued think aloud interviews. Our primary contribution is a set of 77 tactics used, in three categories, along with detail of how common they were. We conclude that people had a lot of tactics in their repertoire. Although it was not hard for participants to find relevant information, what was hard was for participants to find information they could use; indeed only 23% of participants successfully completed the entire task. Domain knowledge affected the choice of tactics used (although not necessarily towards better task success). We discuss these influences and make design recommendations for how future search systems can support those in resolving how-to technical tasks.  相似文献   

Related Multiscreening as a Strategy to Retain Audiences and Increase Persuasion During a Commercial Break     

Claire M. Segijn  Theo Araujo  Hilde A. M. Voorveld  Edith G. Smit 《广播与电子媒介杂志》2020,64(1):41-61

The aim of the study was to deepen our understanding of how related multiscreening affects audience memory and persuasion. A survey was administered after a live television show. The results showed that the higher the perceived relatedness of the multi-screen activity, the more persuasive the message. This effect was mediated by subsequent attention to television content, program involvement, and attention to the commercial break. The model was replicated for three different multiscreen activities: social media use, chatting, and information search. Furthermore, it was found that related multiscreening increased the likelihood of respondents staying tuned to the television after the show.  相似文献   

Training reading and phoneme awareness skills in children with Down syndrome     

Kristina Goetz  Charles Hulme  Sophie Brigstocke  Julia M. Carroll  Louise Nasir  M. Snowling 《Reading and writing》2008,21(4):395-412

The authors report a short-term reading intervention study involving 15 children with Down syndrome (DS) who attended mainstream schools. The intervention programme taught children phoneme segmentation and blending skills in the context of learning letter-sounds and working with words in books. The children were taught by their learning support assistants, who received special training for this purpose. Compared to a waiting group, a group of eight children with DS improved significantly on measures of early literacy skills (letter-sound knowledge, Early Word Recognition) following eight weeks of intervention. The waiting group started to make progress once they received the intervention. Both groups maintained progress on the literacy measures five months after the intervention had finished. The results suggest that children with DS can benefit from structured, phonics-based reading intervention.  相似文献   

The Relation Between Preschoolers’ Vocabulary Development and Their Ability to Predict and Recognize Words     

Chiara Gambi  Priya Jindal  Sophie Sharpe  Martin J. Pickering  Hugh Rabagliati 《Child development》2021,92(3):1048-1066

By age 2, children are developing foundational language processing skills, such as quickly recognizing words and predicting words before they occur. How do these skills relate to children’s structural knowledge of vocabulary? Multiple aspects of language processing were simultaneously measured in a sample of 2-to-5-year-olds (N = 215): While older children were more fluent at recognizing words, at predicting words in a graded fashion, and at revising incorrect predictions, only revision was associated with concurrent vocabulary knowledge once age was accounted for. However, an exploratory longitudinal follow-up (N = 55) then found that word recognition and prediction skills were associated with rate of subsequent vocabulary development, but revision skills were not. We argue that prediction skills may facilitate language learning through enhancing processing speed.  相似文献   

Capacité cognitive,sentiment d’auto-efficacité et autorégulation     

Thérèse Bouffard-Bouchard  Sophie Parent  Serge Larivée 《European Journal of Psychology of Education - EJPE》1990,5(3):355-364

Feelings of self-efficacy have been the object of several studies that have confirmed its ability to predict performance in different contexts. Yet few studies have been conducted using cognitive or academic tasks in which it is more difficult to clearly distinguish self-efficacy from competence. The present study aims to study the moderating role of cognitive capacity in determining the relationship between self-efficacy and on-line self-regulation observed while solving a verbal concept formation task. In order to distinguish self-efficacy from competence, 44 subjects were selected based on the results of their SSPI; these results of which are related to comprehension ability. Analyses of results allow us to observe that, when compared to subjects who consider themselves less efficacious, subjects who have strong feelings of self-efficacy have a higher success rate, are more certain of these successes and reject fewer correct hypotheses, no matter what their cognitive ability. These results once again bring to light the relative independance of cognitive ability and motivational determinants of a person’s actual accomplishments.  相似文献   

The art of the organiser: Raphael Samuel and the origins of the History Workshop     

Sophie Scott-Brown 《History of education》2016,45(3):372-390

The History Workshop movement took its stance on the democratisation of history making, becoming notorious for its exuberant gatherings and impassioned ‘histories from below’. At the centre of the early Workshop was the British historian Raphael Samuel, who has been described as the personification of its intellectual and ethical politics. This paper examines Samuel’s role in the Workshop arguing that his distinctive intellectual personality was critical in shaping its early form and ethos. Drawing on a biographical approach, it explores the development of this persona over the course of his formative years. It argues that Samuel’s life history provides an insight into the renewed appeal of libertarian ideas in post-war British radical political and educational thought and that as an individual he illuminates the application of these ideas to the social role of the historian-educator.  相似文献

A Review of Collegiate Recovery Communities and Recommendations for Implementation on a Small Residential Campus     

Sophie C. Staton  Kelly Melekis  Peter McCarthy 《Innovative Higher Education》2018,43(6):447-462

Although the Collegiate Recovery Community is increasingly seen as the treatment modality of choice for students in recovery, relatively few such programs have been established on small residential campuses. In this article we examine the possible reasons for this reluctance and suggest ways in which the standard model for a Collegiate Recovery Community, as represented by its three benchmark programs, can be modified and adapted to better fit the small residential campus environment. We summarize the problem and review the concept of a Collegiate Recovery Community, and we then explain and recommend 1) a bottom-up initiative for planning and 2) scaled-down resource demand and utilization. We provide a 5-point plan for a “bottom-up, scaled-down” Collegiate Recovery Community on a small residential campus.  相似文献   

A physically active lifestyle is related to a lower level of skin autofluorescence in a large population with chronic-disease (LifeLines cohort)     

Saskia Corine van de Zande  Jeroen Klaas de Vries  Inge van den Akker-Scheek  Johannes Zwerver  Andries Jan Smit 《运动与健康科学(英文)》2022,11(2):260-265

Background:Physical activity(PA)has substantial health benefits and is important in combatting chronic diseases,which have been associated with elevated levels of advanced glycation endproducts(AGEs).AGEs play a role in the aging process,and an association between PA and AGEs has been reported.We aimed to investigate the relationship between PA and AGE accumulation in a general population and in a population with chronic diseases.Methods:This large cross-sectional population study used data from adult participants in the LifeLines project,with participant information drawn from the LifeLines database as well data from patients with diabetes mellitus or renal and/or cardiovascular diseases.Tissue AGE accumulation was assessed non-invasively by skin-autofluorescence(SAF)using an AGE reader(DiagnOptics Technologies BV,Groningen,the Netherlands).PA was assessed using the short questionnaire to assess health-enhancing physical activity(SQUASH).Multivariate linear regression analyses were adjusted for age,body mass index,sex,and smoking status.Results:Data from 63,452 participants(general population n=59,177,chronic disease n=4275)were analyzed.The general population was significantly younger(43.58±11.77 years,mean±SD)and had significantly lower SAF(1.90±0.42 arbitrary units(AU))compared to the population with chronic disease(age:55.51±12.07 years;SAF:2.27±0.51 AU).In the group with chronic disease,more hours of moderate to vigorous physical activities per week were associated with lower SAF(β=-0.002,95%confidence interval(95%CI):-0.002 to-0.001).For the general population,there was no association between hours of moderate to vigorous activity and SAF(β=3.2×10^-5,95%CI:0.000-0.001,p=0.742).However,there was an association in the general population between total hours of PA per week and SAF(β=4.2×10^-4,95%CI:0.000-0.001,p<0.001),but this association was not found in the chronic disease population(β=-3.2×10^-4,95%CI:-0.001 to 0.000,p=0.347).Conclusion:Our study demonstrates that an inverse relationship exists between PA and AGE accumulation in the population with chronic disease.More hours of moderate to vigorous activity is associated a significantly decreased SAF.More PA is associated a lower SAF,even after for the established predictors(age,body mass index,smoking status,and sex).Our findings could help to promote health and prolong longevity.  相似文献   

The Psychometric Properties of the Short and Long Versions of the Coach–Athlete Relationship Questionnaire     

Sophie Xin Yang  Sophia Jowett 《Measurement in physical education and exercise science》2013,17(4):281-294

The Coach–Athlete Relationship Questionnaire was developed to effectively measure affective, cognitive, and behavioral aspects, represented by the interpersonal constructs of closeness, commitment, and complementarity, of the quality of the relationship within the context of sport coaching. The current study sought to determine the internal reliability and factorial validity of the long (the 29-item Long Version Coach–Athlete Relationship Questionnaire) and short (11-item Coach–Athlete Relationship Questionnaire and 13-item Greek Coach–Athlete Relationship Questionnaire) versions of the Coach–Athlete Relationship Questionnaire with a sample of 800 Chinese coaches and athletes. Results supported the internal reliability across all Coach–Athlete Relationship Questionnaire versions examined, while confirmatory factor analyses (CFA) only supported the factorial validity of the three-factor first-order model of the 11-item Coach–Athlete Relationship Questionnaire. The results are discussed in terms of their implications for theory, research, and practice.  相似文献
