Learning and Collective Knowledge Construction With Social Media: A Process-Oriented Perspective     

Joachim Kimmerle  Johannes Moskaliuk  Aileen Oeberst  Ulrike Cress 《教育心理学家》2013,48(2):120-137

Social media are increasingly being used for educational purposes. The first part of this article briefly reviews literature that reports on educational applications of social media tools. The second part discusses theories that may provide a basis for analyzing the processes that are relevant for individual learning and collective knowledge construction. We argue that a systems-theoretical constructivist approach is appropriate to examine the processes of educational social media use, namely, self-organization, the internalization of information, the externalization of knowledge, and the interplay of externalization and internalization providing the basis of a co-evolution of cognitive and social systems. In the third part we present research findings that illustrate and support this systems-theoretical framework. Concluding, we discuss the implications for educational design and for future research on learning and collective knowledge construction with social media.  相似文献   

Sex differences in secondary school success: why female students perform better   总被引：1，自引：0，他引：1  

Franziska Fischer  Johannes Schult  Benedikt Hell 《European Journal of Psychology of Education - EJPE》2013,28(2):529-543

School success is closely linked to intelligence but also to non-cognitive factors such as achievement motivation. The present study examines which non-cognitive factors predict secondary school grades and looks at reasons why female students tend to outperform their male counterparts. A sample of 554 German freshman students provided measures of general intelligence, achievement motivation, science course choice, self-efficacy, self-perceived academic achievement, and test anxiety. Results show that achievement motivation, self-perceived academic achievement, and sex significantly contribute to the final secondary school success above intelligence. Females’ advantage in final secondary school grades becomes even larger after controlling for general intelligence. This advantage can be explained by females’ higher achievement motivation. Showing more compensatory effort as well as self-control and taking more pride in their own productivity helps females to outperform their male counterparts at secondary school.  相似文献   

Bildung und Familienentwicklung im Lebensverlauf     

Johannes Huinink 《Zeitschrift für Erziehungswissenschaft》2000,3(2):209-227

Der Zusammenhang zwischen Bildungsbeteiligung, Bildungsabschluss und Familienentwicklung ist kompliziert. Die g?ngige These einer negativen Beziehung zwischen Bildungserfolg und Heiratsbzw. Geburtenneigung greift theoretisch und empirisch zu kurz. Unter der Annahme, dass ein gleichbleibend starkes Bedürfnis nach engen, pers?nlichen Beziehungen und nach Elternschaft unterstellt werden kann, dürfte die Bedeutung der Bildung nur unter Berücksichtigung der jeweiligen M?glichkeiten zur L?sung von Vereinbarkeitsproblemen zutreffend zu charakterisieren sein.  相似文献   

Sport-specific functional movement can simulate aspects of neuromuscular fatigue occurring in team sports     

Jan Wilke  Johannes Fleckenstein  Frieder Krause  Lutz Vogt  Winfried Banzer 《Sports biomechanics / International Society of Biomechanics in Sports》2016,15(2):151-161

Fatigue protocols have been used over the years to examine muscular exhaustion. As an alternative to approaches in laboratory settings, functional agility protocols claiming to mimic the multifaceted loads of athletic activity have been proposed. This study aimed to examine the effects of a functional agility short-term fatigue protocol (FAST-FP) on neuromuscular function. Twenty-eight healthy sports students (15 males, aged 24.3 ± 2.4 years) completed the FAST-FP, which consists of four components: three counter-movement jumps (90% of individual maximum), a 20-s bout of step-ups, three bodyweight squats and an agility run. Tasks were repeated until the participants no longer achieved the required jump height in two consecutive sets. Outcomes (pre-post) encompassed subjective exhaustion (visual analogue scale [VAS]), maximum isometric voluntary force of the knee extensors (MIVF), reactive strength index (RSI), mean power frequency (MPF, measured using surface electromyography) and maximum knee range of motion (ROM). Post-intervention, VAS (+54 mm) increased significantly, while MIVF (–6.1%), RSI (–10.7%) and MPF (–4.1%) were reduced (p < 0.05). No changes were observed for ROM (p > 0.05). The FAST-FP induces small-to-moderate impairments in neuromuscular function and considerable self-perceived fatigue. Current evidence on exhaustion developing in team sports suggests that this magnitude of fatigue is similar. The protocol might thus be valuable in the evaluation of treatments counteracting post-match fatigue in team sports.  相似文献   

The adolescent motor performance development of elite female soccer players: A study of prognostic relevance for future success in adulthood using multilevel modelling

ABSTRACT

Considering the scarce empirical evidence regarding talent predictors in female youth soccer, the present study aimed to investigate the long-term prognostic validity of elite female soccer players’ adolescent motor performance for future success in adulthood. Additionally, the three-year development of highly talented girls’ motor performance and the predictive value of this motor development for reaching a professional adult performance level (APL) was analysed.

Overall, N = 737 female players participated in nationwide motor diagnostics (sprinting, agility, dribbling, ball control, shooting) within the German Soccer Association’s talent identification and development programme at least twice between the age groups Under-12 (U12) and U15. Based on their APL at least four years later, participants were assigned to a professional (first German division, 6.2%) or non-professional group (lower divisions, 93.8%).

Multilevel regression analyses revealed a general prognostic relevance for the investigated parameters with respect to players’ APL. In addition, there was a non-linear improvement in participants’ motor performance across all variables from U12 to U15. However, non-significant interactions between APL and these improvements indicate motor performance development itself cannot adequately predict players’ future success in adulthood. Findings provide insightful information that can help coaches foster optimal support for young female soccer players’ development.  相似文献   

Usages and impacts of the integration of information and communication technologies (ICTs) in elementary classrooms: case study of Swedish municipality schools     

Johannes S. Sahlin  Antony Tsertsidis  M. Sirajul Islam 《Interactive Learning Environments》2017,25(5):561-579

During recent years, many schools have started to implement information and communication technologies (ICTs)-based learning devices (such as laptops, tablets, mobile phones, and active boards) in the classroom settings in order to increase learning outcomes. The aim of this study is to find which activities and outcomes are evident in the usages of computing devices and how those devices aid elementary-level students in their learning activities. The study includes five overt participant observations at some schools in a Swedish municipality including unstructured interviews and explains the findings through activity theory and the Alberta Education Framework for Student Learning . The major activities found were dealing with the (1) educational application assignments, (2) storytelling, (3) report writing and (4) practical interaction assignments. We concluded that ICTs aid students in becoming more concentrated, focus driven, engaged and amused, thus learning becomes more interesting.  相似文献   

EDUCATION,FAIR COMPETITION,AND CONCERN FOR THE WORST OFF     

Johannes Giesinger 《Educational theory》2011,61(1):41-54

In this essay, Johannes Giesinger comments on the current philosophical debate on educational justice. He observes that while authors like Elizabeth Anderson and Debra Satz develop a so‐called adequacy view of educational justice, Harry Brighouse and Adam Swift defend an egalitarian principle. Giesinger focuses his analysis on the main objection that is formulated, from an egalitarian perspective, against the adequacy view: that it neglects the problem of securing fair opportunities in the competition for social rewards. Giesinger meets this objection by expressing two basic theses: First, he argues that Brighouse and Swift themselves fail to give an adequate account of fair competition; and, second, he shows that the adequacy view provides the theoretical resources to face this problem.  相似文献   

Can information ethics be conceptualized by using the core/periphery model?     

Dennis N. Ocholla  Omwoyo Bosire Onyancha  Johannes Britz 《Journal of Informetrics》2010,4(4):492-502

The term ‘information ethics’ (IE) is rapidly diversifying as new technologies enter the milieu and add to already existing ‘entanglements’. Unsurprisingly, the term lacks a universally accepted definition, although there is some common ground as to its constitution. This paper explores the term using the most commonly co-occurring terms in IE literature as indexed in nine databases, namely the EBSCO-hosted Academic Search Premier (ASP); Communication and Mass Media Complete; ERIC; Library, Information Science and Technology Abstracts (LISTA); Newspaper Complete; Business Premier; and Master File Premier, and Wilson's Library Literature and Information Science (LLIS) Full Text. Core/periphery analysis, the co-occurrence of words as subject terms, and social network techniques were applied using UCINET for Windows, text STAT and Bibexcel computer-aided software to analyze data. The paper identifies the most common terms used to describe IE and the core terms with which IE can be defined. Other than informing LIS research and education, the results could potentially assist with the development of IE taxonomy and definitions (e.g. in understanding IE content and development) that may apply to the intercultural and global understanding of IE.  相似文献   

Fetal Genotype for the Xenobiotic Metabolizing Enzyme NQO1 Influences Intrauterine Growth Among Infants Whose Mothers Smoked During Pregnancy     

Thomas S. Price  Tilo Grosser  Robert Plomin  Sara R. Jaffee 《Child development》2010,81(1):101-114

Maternal smoking during pregnancy retards fetal growth and depresses infant birth weight. The magnitude of these effects may be moderated by fetal genotype. The current study investigated maternal smoking, fetal genotype, and fetal growth in a large population sample of dizygotic twins. Maternal smoking retarded fetal growth in a dose-dependent fashion. In a subsample of 497 twin pairs whose mothers smoked during pregnancy, a functional polymorphism in the NAD(P)H:quinone oxidoreductase gene ( NQO1 Pro187Ser; rs1800566) was significantly associated with fetal growth within families. The effect was strongest among moderate smokers. This is the first demonstration that fetal genotype for an enzyme involved in tobacco smoke metabolism influences intrauterine growth independent of maternal genotype. Future studies should conduct formal tests of Fetal Genotype × Maternal Smoking interactions.  相似文献
