Granularity of algorithmically constructed publication-level classifications of research publications: Identification of topics     

Peter Sjögårde  Per Ahlgren 《Journal of Informetrics》2018,12(1):133-152

The purpose of this study is to find a theoretically grounded, practically applicable and useful granularity level of an algorithmically constructed publication-level classification of research publications (ACPLC). The level addressed is the level of research topics. The methodology we propose uses synthesis papers and their reference articles to construct a baseline classification. A dataset of about 31 million publications, and their mutual citations relations, is used to obtain several ACPLCs of different granularity. Each ACPLC is compared to the baseline classification and the best performing ACPLC is identified. The results of two case studies show that the topics of the cases are closely associated with different classes of the identified ACPLC, and that these classes tend to treat only one topic. Further, the class size variation is moderate, and only a small proportion of the publications belong to very small classes. For these reasons, we conclude that the proposed methodology is suitable to determine the topic granularity level of an ACPLC and that the ACPLC identified by this methodology is useful for bibliometric analyses.  相似文献   

Development and validation of the Perceived Game-Specific Soccer Competence Scale     

Hannele Forsman  Arto Gråstén  Minna Blomqvist  Keith Davids  Jarmo Liukkonen  Niilo Konttinen 《Journal of sports sciences》2016,34(14):1319-1327

ABSTRACT

The objective of this study was to create a valid, self-reported, game-specific soccer competence scale. A structural model of perceived competence, performance measures and motivation was tested as the basis for the scale. A total of 1321 soccer players (261 females, 1060 males) ranging from 12 to 15 years (13.4 ± 1.0 years) participated in the study. They completed the Perceived Game-Specific Soccer Competence Scale (PGSSCS), self-assessments of tactical skills and motivation, as well as technical and speed and agility tests. Results of factor analyses, tests of internal consistency and correlations between PGSSCS subscales, performance measures and motivation supported the reliability and validity of the PGSSCS. The scale can be considered a suitable instrument to assess perceived game-specific competence among young soccer players.  相似文献   

Development of perceived competence,tactical skills,motivation, technical skills,and speed and agility in young soccer players     

Hannele Forsman  Arto Gråstén  Minna Blomqvist  Keith Davids  Jarmo Liukkonen  Niilo Konttinen 《Journal of sports sciences》2016,34(14):1311-1318

ABSTRACT

The objective of this 1-year, longitudinal study was to examine the development of perceived competence, tactical skills, motivation, technical skills, and speed and agility characteristics of young Finnish soccer players. We also examined associations between latent growth models of perceived competence and other recorded variables. Participants were 288 competitive male soccer players ranging from 12 to 14 years (12.7 ± 0.6) from 16 soccer clubs. Players completed the self-assessments of perceived competence, tactical skills, and motivation, and participated in technical, and speed and agility tests. Results of this study showed that players’ levels of perceived competence, tactical skills, motivation, technical skills, and speed and agility characteristics remained relatively high and stable across the period of 1 year. Positive relationships were found between these levels and changes in perceived competence and motivation, and levels of perceived competence and speed and agility characteristics. Together these results illustrate the multi-dimensional nature of talent development processes in soccer. Moreover, it seems crucial in coaching to support the development of perceived competence and motivation in young soccer players and that it might be even more important in later maturing players.  相似文献   

Organising and leading systematic quality work in the preschool – preschool managers’ perspectives     

Jan Håkansson 《School Leadership & Management》2016,36(3):292-310

Preschool managers’ responsibility for and leadership of systematic quality work has come to the fore in connection with changes made to the Swedish preschool curriculum. The aim of this study is to contribute to the understanding of preschool managers’ leadership and management of the systematic quality work in Swedish preschools with reference to three specific domains: (i) governance, leadership/management and organisation, (ii) content and methods and (iii) development work and collegiate learning. Using qualitative methods, 18 preschool managers’ perspectives of leading systematic quality work have been analysed in relation to previous research. The results show a tension between linear and interactive forms of governance in the systematic quality work, but also that knowledge gaps among the staff can lead to uncertainties that the preschool manager has to address. At the same time, the results show the diversity of and variation in how children’s development and increased proficiency are documented, while the documentation of the quality of the work focuses on learning environments rather than on teaching and teacher competence. In the study, there are traces of what can be characterised as leadership for learning. This needs to be investigated more closely using other methods in future research.  相似文献   

Equality and excellence. Hegemonic discourses of economisation within the German education system     

Tobias Peter  Ulrich Bröckling 《International Studies in Sociology of Education》2017,26(3):231-247

Looking to conflicting constitutions of education systems through the terms equality and excellence, this paper examines the discursive formation of two political rationalities in the contemporary German education system. While early childhood and primary education discourses are dominated by a terminology of equality, tertiary education institutions such as universities are described using a terminology of excellence that has become a reference point for political interventions and institutional reform processes. Drawing from hegemony theory, governmentality studies and systems theory, this paper analyses the rules of justification referred to by such hegemonic discourses. It presents a policy discourse analysis of strategic, conceptional and institutional texts produced between 2003 and 2010. Through this analysis, the paper suggests that ‘mobilising’ and ‘optimising’ represent the common principles of equality and excellence as economic rationalities.  相似文献   

Validation of the elementary social behaviour assessment: teacher ratings of students’ social skills adapted to Norwegian,grades 1–6     

Anne Arnesen  Keith Smolkowski  Terje Ogden  Monica Melby-Lervåg 《Emotional and Behavioural Difficulties》2018,23(1):39-54

This study investigated the psychometric properties of the Elementary Social Behaviour Assessment (ESBA), a teacher-report measure of students’ social skills and academic engagement adapted for use in Norwegian schools. At two times, 8 weeks apart, 151 teachers rated 793 students in Grades 1–6 on the ESBA and the Social Skills Rating System Teacher’s form (SSRS-T). Exploratory factor analysis with the first assessment suggested one or possibly two factors. Confirmatory factor analysis with the second assessment confirmed the one- or two-factor models but did not offer strong evidence for one over the other. The ESBA demonstrated good to excellent reliability. Strong concurrent and predictive correlations with the SSRS-T established criterion validity. The school and teacher levels explained only a limited amount of the total variance in ESBA scores, suggesting that teachers rate students quite similarly. The Norwegian-adapted ESBA paralleled the reliability and validity evidence from US samples.  相似文献   

The promises and limitations of international comparative research on teacher education     

Hilde Wågsås Afdal 《欧洲师范教育杂志》2019,42(2):258-275

This article revisits methodological perspectives on international comparative research on teacher education (TE). Benefits and problems related to comparative educational research methodology in general are discussed. Further, methodological issues associated with designing and carrying out an international comparative study on TE are addressed using a multi-level study on teacher education in Finland and Norway an as example. Towards the end of the article, the promises and limitations of international comparative research on TE are presented. Important benefits of comparative education on TE include widening the understanding of one’s own and other TE systems as well as gaining an understanding of international trends. However, uncritical use of such research may lead to decontextualised, ahistorical and standardised transfer and development of education and educational policies. The article concludes by urging researchers in the field of international comparative research on teacher education to address the questions: What is being compared? How is context addressed?  相似文献   

Writing and pseudo‐writing from Internet‐based sources: implications for learning and assessment          下载免费PDF全文

Håvard Skaar 《Literacy》2015,49(2):69-76

In recent years, plagiarism has been on the increase across the Western world. This article identifies Internet access as a contributory cause of this trend and addresses the implications of readily available Internet sources for the teaching and assessment of writing in schools. The basis for the article is a previous study showing a wide incidence of plagiarism in the Internet‐based writing of students in three classes at upper secondary school level in Norway. I relate the students' choices to writing as a cognitive process and as a cultural practice. My basic assumption is that the students' writing is work. It is this work we have in mind when we relate writing to learning and when we assess students' skills on the basis of their written texts. Access to the Internet changes the premises for this work because writing can be replaced by ‘pseudo‐writing’. ‘Pseudo‐writing’ is a work reducing writing practice, which neither excludes nor coincides with what we traditionally associate with plagiarism in schools. The main point in this article is that when students have access to the Internet during essay writing, the result is unavoidably a product of both writing and pseudo‐writing. Internet access thus leads to greater uncertainty about the role writing plays in student learning and makes it more difficult to take written assignments into account in assessing students' school results and effort.  相似文献

Small Circles: Mobile Telephony and the Cultivation of the Private Sphere     

Rich Ling  Johannes Bjelland  Pål Roe Sundsøy  Scott W. Campbell 《The Information Society》2014,30(4):282-291

This article examines how we use mobile telephony to maintain our physically and socially closest social circle. The analysis is based on traffic data gathered from Norway using approximately 24 million calls and texts made by private individuals. Previous research has shown that our temporal and spatial movement is highly predictable and that the majority of calls and text messages are sent to only four to six different persons. This article extends this research by examining both tie strength and the distance between the interlocutors in urban and rural settings. The findings show that even as information and communication technologies (ICTs) potentially put the world at our fingertips, the mobile phone is an instrument of a more limited geographical and social sphere. Approximately two-thirds of our calls/texts go to strong ties that are within a 25-km radius.  相似文献
