Parental Nurturance Promotes Reading Acquisition in Low Socioeconomic Status Children     

Lisa J. Merlo  Margo Bowman  Douglas Barnett 《Early education and development》2013,24(1):51-69

Research Findings: Children require cognitive skills (e.g., phoneme awareness, verbal intelligence) and environmental resources (e.g., stimulation, print exposure) to acquire reading. This investigation examined the additional contribution of parental nurturance to literacy development during the transition from preschool to elementary school. Participants were 77 children attending Head Start, their primary caregivers, and their teachers. A variety of methods were used to measure nurturance (e.g., self-report, laboratory observation, home observation) and reading achievement (e.g., standardized testing and teacher report). Approximately 3½ years later, 52 families and 39 teachers were available for repeat assessments of children's reading achievement. After controlling for the variance accounted for by prior reading ability, phonological awareness, verbal reasoning ability, and home academic stimulation, parental nurturance made a significant unique contribution to children's growth in reading achievement. Results supported the hypothesis that caregiver nurturance can be an important ingredient in the recipe for literacy.

Practice: The findings have important implications for the design of interventions for children with low reading achievement. By understanding the various ways in which parents foster reading, interventions can be developed to bolster parental nurturance and support the role of nurturance in promoting children's development in all areas, including intellectual and academic functioning.  相似文献   

In search of the excellent literature teacher. An inductive approach to constructing professional teaching standards     

T.C.H. Witte  E.P.W.A. Jansen 《Teachers and Teaching》2013,19(5):565-583

This study makes a contribution to the development of empirically based, domain-specific teaching standards that are acknowledged by the professional community of teachers and which, therefore, have a good chance of being successfully implemented and used for professional development purposes. It was prompted by the resistance on the part of many teachers to the one-size-fits-all teaching standards imposed on them from above. We, therefore, looked for an alternative and canvassed teacher opinion about what makes an excellent literature teacher. Because our standards will be used to evaluate the profession, we also wished to know to what extent teachers satisfy (or would like to satisfy) their own ideal, and which factors influence their professional development. Contrary to earlier studies, we found that the professional community of literature teachers hold widely shared ideas about what constitutes excellence in their profession. We also found that almost 40% felt that their own level of professionalism fell far short of excellence, but that their professional growth was primarily hampered by external, contextual factors. If the government wishes to promote teacher ‘excellence’, the infrastructure for professional development will need to change so that teachers can acquire the knowledge and skills embodied in the teaching standards.  相似文献   

Evaluating the performance of demographic targeting using gender in sponsored search     

Bernard J. Jansen  Kathleen Moore  Stephen Carman 《Information processing & management》2013

In this research, we evaluate the effect of gender targeted advertising on the performance of sponsored search advertising. We analyze nearly 7,000,000 records spanning 33 consecutive months of a keyword advertising campaign from a major US retailer. In order to determine the effect of demographic targeting, we classify the campaign’s key phrases by a probability of being targeted for a specific gender, and we then compare the key performance indicators among these groupings using the critical sponsored search metrics of impressions, clicks, cost-per-click, sales revenue, orders, and items, and return on advertising. Findings from our research show that the gender-orientation of the key phrase is a significant determinant in predicting behaviors and performance, with statistically different consumer behaviors for all attributes as the probability of a male or female keyword phrase changes. However, gender neutral phrases perform the best overall, generating 20 times the return of advertising than any gender targeted category. Insight from this research could result in sponsored advertising efforts being more effectively targeted to searchers and potential consumers.  相似文献   

The Contextual Benchmark Method: Benchmarking e-Government services     

Jurjen Jansen  Sjoerd de Vries  Paul van Schaik 《Government Information Quarterly》2010

This paper offers a new method for benchmarking e-Government services. Government organizations no longer doubt the need to deliver their services on line. Instead, the question that is more relevant is how well the electronic services offered by a particular organization perform in comparison with those offered by others. Benchmarking is currently a popular means of answering that question. The benchmarking of e-Government services has reached a critical stage where, as we argue, simply measuring the number of electronic services is not enough and a more sophisticated approach is needed. This paper details the development of a Contextual Benchmark Method (CBM). The value of CBM is that it is both benchmark- and context-driven.  相似文献   

Increased physical education at school improves the visual-spatial cognition during adolescence     

Petra Jansen  Jan Ellinger  Jennifer Lehmann 《教育心理学》2018,38(7):964-976

The main goal of this study was to investigate the influence of an established school programme with a high amount of physical education on visual-spatial ability in a secondary school. One hundred and forty-four adolescents, 69 from sport classes and 75 from regular classes, solved a cognitive processing speed task and a mental rotation task. The results reflect a better cognitive processing speed of the boys in the sports classes compared to regular classes but no differences for girls. Concerning the mental rotation performance, we found a significantly better mental rotation performance for boys and girls in the sports classes compared to regular classes due to an increased number of items worked on. Supposedly, motor expertise facilitates mental rotation performance by promoting a faster editing of the task. The benefits of sport classes in normal high school settings have to be investigated in further studies considering the effect on academic performance.  相似文献   

A study of medical and health queries to web search engines     

Spink A  Yang Y  Jansen J  Nykanen P  Lorence DP  Ozmutlu S  Ozmutlu HC 《Health information and libraries journal》2004,21(1):44-51

This paper reports findings from an analysis of medical or health queries to different web search engines. We report results: (i). comparing samples of 10000 web queries taken randomly from 1.2 million query logs from the AlltheWeb.com and Excite.com commercial web search engines in 2001 for medical or health queries, (ii). comparing the 2001 findings from Excite and AlltheWeb.com users with results from a previous analysis of medical and health related queries from the Excite Web search engine for 1997 and 1999, and (iii). medical or health advice-seeking queries beginning with the word 'should'. Findings suggest: (i). a small percentage of web queries are medical or health related, (ii). the top five categories of medical or health queries were: general health, weight issues, reproductive health and puberty, pregnancy/obstetrics, and human relationships, and (iii). over time, the medical and health queries may have declined as a proportion of all web queries, as the use of specialized medical/health websites and e-commerce-related queries has increased. Findings provide insights into medical and health-related web querying and suggests some implications for the use of the general web search engines when seeking medical/health information.  相似文献

How are we searching the World Wide Web? A comparison of nine search engine transaction logs     

Bernard J. Jansen  Amanda Spink 《Information processing & management》2006

The Web and especially major Web search engines are essential tools in the quest to locate online information for many people. This paper reports results from research that examines characteristics and changes in Web searching from nine studies of five Web search engines based in the US and Europe. We compare interactions occurring between users and Web search engines from the perspectives of session length, query length, query complexity, and content viewed among the Web search engines. The results of our research shows (1) users are viewing fewer result pages, (2) searchers on US-based Web search engines use more query operators than searchers on European-based search engines, (3) there are statistically significant differences in the use of Boolean operators and result pages viewed, and (4) one cannot necessary apply results from studies of one particular Web search engine to another Web search engine. The wide spread use of Web search engines, employment of simple queries, and decreased viewing of result pages may have resulted from algorithmic enhancements by Web search engine companies. We discuss the implications of the findings for the development of Web search engines and design of online content.  相似文献   

Student teachers’ participation in learning activities and effective teaching behaviours     

Siebrich de Vries  Ellen P.W.A. Jansen  Michelle Helms-Lorenz  Wim J.C.M. van de Grift 《欧洲师范教育杂志》2015,38(4):460-483

Teacher learning is essential to the teaching profession, because it has been strongly linked to improved teaching practices and teacher quality. The source for teacher learning is initial teacher education, a crucial phase in the learning-to-teach continuum. To gain insight into this influential period for student teachers’ long-term professional lives, this exploratory study investigates student teachers’ participation in learning activities and explores whether it is connected to their own effective teaching behaviours in a school-based teacher education setting for secondary education in the Netherlands. The results indicate that student teachers vary in their self-reported learning and that this learning relates positively to observations of their effective teaching behaviour. These findings have several implications for teacher education programmes that aim to enhance the likelihood that their student teachers will become career-long learning professionals.  相似文献   

Time series analysis of a Web search engine transaction log     

Ying Zhang  Bernard J. Jansen  Amanda Spink 《Information processing & management》2009

In this paper, we use time series analysis to evaluate predictive scenarios using search engine transactional logs. Our goal is to develop models for the analysis of searchers’ behaviors over time and investigate if time series analysis is a valid method for predicting relationships between searcher actions. Time series analysis is a method often used to understand the underlying characteristics of temporal data in order to make forecasts. In this study, we used a Web search engine transactional log and time series analysis to investigate users’ actions. We conducted our analysis in two phases. In the initial phase, we employed a basic analysis and found that 10% of searchers clicked on sponsored links. However, from 22:00 to 24:00, searchers almost exclusively clicked on the organic links, with almost no clicks on sponsored links. In the second and more extensive phase, we used a one-step prediction time series analysis method along with a transfer function method. The period rarely affects navigational and transactional queries, while rates for transactional queries vary during different periods. Our results show that the average length of a searcher session is approximately 2.9 interactions and that this average is consistent across time periods. Most importantly, our findings shows that searchers who submit the shortest queries (i.e., in number of terms) click on highest ranked results. We discuss implications, including predictive value, and future research.  相似文献
