ABSTRACT

The present study examined the efficacy of a coaching curriculum, based on non-linear pedagogy, on improving attacking players’ individual learning objectives (ILOs) in elite-youth football. Participants included 22 attacking players (i.e., centre-forwards, wide-players and attacking midfield players) from a professional football academy in England. The players were randomly appointed to both control (CON) and intervention (INT) periods following baseline measures. The INT (non-linear) and CON (linear) periods were both designed to support the ILOs provided to each player as part of the elite player performance plan. The study adopted a randomised cross-over design and ILOs considered important for attacking players (i.e., strong foot finishing, weak foot finishing, 1-v-1 and decision-making) were evaluated using the Loughborough Shooting Skill Test. The results showed significant differences for INT in 1-v-1 (P< 0.02) and decision-making (P< 0.01). However, there were no significant differences for strong foot finishing, weak foot finishing or time taken. These results support non-linear pedagogy in developing 1-v-1 game play and decision-making but not for technical shooting proficiency.  相似文献   

Early career mathematics teachers: Concepts,methods, and strategies for comparative international research     

《Teaching and Teacher Education》2020

In this article, we report on the challenges entailed in the development of concepts, methods, and strategies for designing and implementing a cross-national research study of the first-years of school-mathematics teaching, including an exploration of how beginning mathematics teachers differ in their preparation, knowledge for teaching, teaching practice, working conditions, and pupil characteristics. The study was designed as a proof-of-concept for a study of teaching and teacher education to be implemented by educationalists, teacher educators, and early career teachers as an ongoing professional endeavor. Primary among the challenges was the development of the sampling design and the construction of measures.  相似文献   

体育强国建设下幼儿家庭体育的现象学研究     

白翠瑾  李哲  杨光 《沈阳体育学院学报》2020,(2):34-40

2019年是中国体育划时代的一年,以《体育强国建设纲要》的颁布为起点开启了体育事业的全新征程。幼儿家庭体育是学前教育的薄弱环节,父母的体育引导是家庭体育的重中之重。采用现象学方法,以幼儿父母访谈为抓手诠释幼儿家庭体育现象。结果认为:父母观念下幼儿家庭体育的掣肘包括主观因素的理念束缚、安全焦虑、指导孱弱、精力局限,客观因素的经济无力、规划无序、保障无依。针对存在障碍提出化解路径:通过革新理念调解传统意识的偏颇,通过制定指南消解育教于体的困惑,通过家园共育缓解精力、经济的压力,通过社会支持纾解供需之间的失衡。  相似文献   

From user-generated data to data-driven innovation: A research agenda to understand user privacy in digital markets     

《International Journal of Information Management》2021

In recent years, strategies focused on data-driven innovation (DDI) have led to the emergence and development of new products and business models in the digital market. However, these advances have given rise to the development of sophisticated strategies for data management, predicting user behavior, or analyzing their actions. Accordingly, the large-scale analysis of user-generated data (UGD) has led to the emergence of user privacy concerns about how companies manage user data. Although there are some studies on data security, privacy protection, and data-driven strategies, a systematic review on the subject that would focus on both UGD and DDI as main concepts is lacking. Therefore, the present study aims to provide a comprehensive understanding of the main challenges related to user privacy that affect DDI. The methodology used in the present study unfolds in the following three phases; (i) a systematic literature review (SLR); (ii) in-depth interviews framed in the perspectives of UGD and DDI on user privacy concerns, and finally, (iii) topic-modeling using a Latent Dirichlet allocation (LDA) model to extract insights related to the object of study. Based on the results, we identify 14 topics related to the study of DDI and UGD strategies. In addition, 14 future research questions and 7 research propositions are presented that should be consider for the study of UGD, DDI and user privacy in digital markets. The paper concludes with an important discussion regarding the role of user privacy in DDI in digital markets.  相似文献

The determinants of stadium attendance in elite women’s football: Evidence from the UEFA Women's Champions League     

《Sport Management Review》2020,23(3):509-520

Women’s football struggles to build a solid platform in terms of fan interest. However, while an increase in gate receipts can help assist its long-term sustainability, there is limited evidence in the academic literature on the factors influencing spectator demand in women’s football. The authors investigate determinants of stadium attendance for UEFA Women's Champions League (UWCL) matches. Using regression models deployed on 554 UWCL games played between 2009/10 and 2017/18, the authors examine contextual and sport-related variables as the main predictors of stadium attendance. Findings show that there is no continuous growth of attendance over the period examined, and highlight that spectators’ interest is positively associated with five factors: stage of the competition, uncertainty of match outcome, competitive intensity, away club’s reputation and weather conditions. Football governing bodies should put in place initiatives to ensure match outcome uncertainty is maintained as this represents a key determinant to maximise stadium attendance. Based on the specific context of European women’s football, recommendations to foster its development are discussed. These include incentivising investment into the elite women’s game and designing sport policies to encourage participation at grassroots levels.  相似文献   

MARC to BIBFRAME: Converting the PCC to Linked Data     

Jacquie Samples  Ian Bigelow 《Cataloging & classification quarterly》2020,58(3-4):403-417

Abstract

The Program for Cooperative Cataloging (PCC) has formal relationships with the Library of Congress (LC), Share-VDE, and Linked Data for Production Phase 2 (LD4P2) for work on Bibliographic Framework (BIBFRAME), and PCC institutions have been very active in the exploration of MARC to BIBFRAME conversion processes. This article will review the involvement of PCC in the development of BIBFRAME and examine the work of LC, Share-VDE, and LD4P2 on MARC to BIBFRAME conversion. It will conclude with a discussion of areas for further exploration by the PCC leading up to the creation of PCC conversion specifications and PCC BIBFRAME data.  相似文献

Dissection in the Modern Medical Curriculum: An Exploration into Student Perception and Adaptions for the Future     

Arunan Jeyakumar  Bhanuka Dissanayake  Lakal Dissabandara 《Anatomical sciences education》2020,13(3):366-380

For centuries cadaveric dissection has been a cornerstone of medical anatomy education. However, time and financial limitations in modern, compressed medical curricula, coupled with the abundance of alternate modalities, have raised questions about the role of dissection. This study was designed to explore student perceptions of the efficacy of a dissection program for learning musculoskeletal anatomy, and possible adaptations for appropriate inclusion of dissection in the modern medical curricula. A paper-based questionnaire was used to collect data from 174 medical students after completion of cadaveric dissections. Data were analyzed using both quantitative and qualitative methods. Students strongly believed that cadaver-based learning is essential to anatomy education and modern teaching modalities only complement this. Moreover, most students reported that dissection provided an additional, immersive learning experience that facilitated active learning and helped in developing manual competencies. Students with previous dissection experience or an interest in anatomy-related specialties were significantly more likely to attend dissection sessions. Students found that the procedural dissection components enhanced the knowledge of applied anatomy and is beneficial for the development of clinical skills. They welcomed the idea of implementing more procedure-based dissections alongside lectures and prosections-based practical (PBP) sessions. Cadaveric dissection plays an integral role in medical anatomy education. Time restraints and an increased focus on clinical significance, however, demand carefully considered adaptations of existing dissection protocols. The introduction of procedure-based dissection offers an innovative, highly engaging and clinically relevant package that would amalgamate skills essential to medical practice while retaining the benefits that have allowed dissection to stand the test of time.  相似文献
