This study investigated whether neuromuscular fatigue affects the neuromuscular control of an athlete within a sports context setting and whether these effects were more pronounced in the females. Lower limb joint kinetics of 6 male and 6 female inter-varsity soccer players performing side-stepping tasks in non-fatigue versus fatigue and anticipated versus unanticipated conditions were quantified using 10 Motion Analysis Corporation cameras and a Kistler^? force platform. The Yo-Yo intermittent recovery Level 1 fatigue protocol was employed. Stance foot initial contact and peak forces, and peak joint knee moments of the lower limb were submitted to a 3-way mixed-model repeated measure ANOVA. The results suggested that males tend to elicit significantly higher knee joint loadings when fatigued. In addition, males elicited significantly higher peak proximal tibia anterior/posterior shear force, vertical ground reaction force at initial contact and peak internal rotational moments than females. These findings suggested that males were at greater overall injury risk than females, especially in the sagittal plane. Neuromuscular control-based training programmes/interventions that are designed to reduce the risk of the non-contact ACL injury need to be customised for the different genders.  相似文献   

Strategies for effective faculty involvement in online activities aimed at promoting critical thinking and deep learning     

Nina Abdul Razzak 《Education and Information Technologies》2016,21(4):881-896

Highly-traditional education systems that mainly offer what is known as direct instruction usually result in graduates with a surface approach to learning rather than a deep one. What is meant by deep-learning is learning that involves critical analysis, the linking of ideas and concepts, creative problem solving, and application (Harvey & Kamvounias, Higher Education Research & Development, 27(1), 31–41, doi: 10.1080/07294360701658716 2008)- all of which prepare graduates for life in the 21st Century. It is precisely this kind of deep learning that the current national educational reform initiatives in Bahrain are trying to promote, in contrast to what has usually been offered historically. Unfortunately, this noble aim is not always achieved and teaching methods need to be examined and developed, since there definitely are a lot of alternatives to stereotype lecturing in academic institutions (Annerstedt, Garza, Huang-DeVoss, Lindh & Rydmark, Journal of the Scholarship of Teaching and Learning, 10(2), 107–127, 2010). One such alternative suggested in this paper is that of increasing faculty involvement with students in online contexts, as a means for promoting critical thinking and deep learning.  相似文献

This study seeks to describe the teachers’ professional development activities in Bangladesh and explores the hypotheses about the relationship between teachers’ traditional professional development activities and school improvement. Data from a representative sample of City secondary schools from Bangladesh (n = 127) were gathered through questionnaires from 127 principals and 694 teachers. Hierarchical multiple regression analysis was used in this research. This study found significant impacts of some of teachers’ professional development activities on school improvement. Also found that the maximum school improvement can be achieved if schools put more emphasis on teachers’ collaboration, in-service training and classroom observation and less emphasis on individual action enquiry. The findings of this study provide important information for the policy makers, educational managers and especially for the headmasters and teachers concerned with the improvement of teachers’ quality in secondary schools of Bangladesh. This study adopts a concurrent approach of data collection and analysis.  相似文献   

Suppressing Memory and Knowledge: A Self-taught Pedagogy     

Abdul Jabbar 《Changing English: An International Journal of English Teaching》2012,19(3):307-312

This article contextualizes the significance of lived experience in relation to personal narratives and learning largely by examining Zainab Salbi’s autobiography Between Two Worlds: Escape from Tyranny: Growing Up in the Shadow of Saddam. Discussing Salbi’s education and personal life as the daughter of Saddam’s private pilot, the article explores the learner’s reluctance to share what Donald Winnicott calls ‘the secret self’. This resistance on the part of the learner complicates the notion of communication as a therapeutic method that educators usually use as the bases for teaching and learning, as explicated by Alice Pitt. In Salbi’s politicized world, she explains how suppressed memory and reluctance to express oneself are tools of survival that ultimately turn into a lifestyle inside and outside the classroom. By employing Winnicott’s metaphor of hide and seek to demonstrate ambivalence in communication, this study explores how Salbi’s experience as a woman with a suppressed personal history can culturally and psychologically be very similar to teachers and students who are reluctant to share their own memories. In effect, this paper examines the implications of suppressed memory and knowledge among reluctant learners for pedagogical practices worldwide.  相似文献   

Contextual influences on sources of academic self-efficacy: a validation with secondary school students of Kerala     

K. Abdul Gafoor  P. Muhammed Ashraf 《Asia Pacific Education Review》2012,13(4):607-616

This study investigates the theorized sources of Academic Self-Efficacy among the higher secondary school students of Kerala, India. Mastery Experience in the form of Academic Achievement, vicarious experience in the form of School Image and Social Persuasion in the form of Parental Encouragement are included as the predictor variables of Academic Self-Efficacy. Participants in the present study were 700 higher secondary school students of Kerala, selected using stratified random sampling. The findings of the study confirm the theorized correlation of Academic Self-Efficacy with previous achievement, vicarious experience (school image) and persuasory information (parental encouragement). In the total sample, the percent of variance in Academic Self-Efficacy that is predictable by the three-predictor variables is nearly one quarter (23.83?%). School Image is the best contributing variable (9.42?%) followed by Mastery Experience (8.67?%) and then by Parental Encouragement (5.74?%). The findings shows that apart from cultural differences, locale and gender difference also exist in sources of Academic Self-Efficacy. The superiority of School Image over Mastery Experience in predicting Academic Self-Efficacy is different from that found in the West, theoretically and empirically. In India, self-efficacy beliefs of youngsters continue to depend more on social and domestic factors than personal experience and mastery.  相似文献   

Additive effects due to biochar and endophyte application enable soybean to enhance nutrient uptake and modulate nutritional parameters     

Muhammad Waqas  Yoon-Ha Kim  Abdul Latif Khan  Raheem Shahzad  Sajjad Asaf  Muhammad Hamayun  Sang-Mo Kang  Muhammad Aaqil Khan  In-Jung Lee 《Journal of Zhejiang University. Science. B》2017,18(2):109-124

We studied the effects of hardwood-derived biochar (BC) and the phytohormone-producing endophyte Galactomyces geotrichum WLL1 in soybean (Glycine max (L.) Merr.) with respect to basic, macro- and micronutrient uptakes and assimilations, and their subsequent effects on the regulation of functional amino acids, isoflavones, fatty acid composition, total sugar contents, total phenolic contents, and 1,1-diphenyl-2-picrylhydrazyl (DPPH)-scavenging activity. The assimilation of basic nutrients such as nitrogen was up-regulated, leaving carbon, oxygen, and hydrogen unaffected in BC+G. geotrichum-treated soybean plants. In comparison, the uptakes of macro- and micronutrients fluctuated in the individual or co-application of BC and G. geotrichum in soybean plant organs and rhizospheric substrate. Moreover, the same attribute was recorded for the regulation of functional amino acids, isoflavones, fatty acid composition, total sugar contents, total phenolic contents, and DPPH-scavenging activity. Collectively, these results showed that BC+G. geotrichum-treated soybean yielded better results than did the plants treated with individual applications. It was concluded that BC is an additional nutriment source and that the G. geotrichum acts as a plant biostimulating source and the effects of both are additive towards plant growth promotion. Strategies involving the incorporation of BC and endophytic symbiosis may help achieve eco-friendly agricultural production, thus reducing the excessive use of chemical agents.  相似文献

INTRODUCTION Rice (Oryza sativa L.) is one of the most im-portant crops in Pakistan. It is the third largest crop interms of area and production after wheat and cotton.Although rice in Pakistan is consuming large acreage,Pakistan is still far behind other rice producingcountries. The average yield is very low (2 t/ha) ascompared to Egypt (8.4 t/ha) and USA (6.6 t/ha).There are many reasons for this low yield. The mostimportant are high temperature (40?50 °C), low hu-midity at …  相似文献   

Some reflections on education for rural development     

Abdul Muyeed 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》1982,28(2):227-238

The article stresses the significance of anti-poverty oriented rural development for developing countries and the need to identify the educational implications of such a strategy. Some of the assumptions derived from contemporary experience in development, and in particular rural development, which are vital for understanding and formulating the role of education, are presented and analysed. The indicators used in the measurement of anti-poverty rural development bring clarity to the concept of interlinking development and education in concrete terms. Some features of education for rural development are discussed and the significance of four areas of educational activities underscored, namely, primary education, functional literacy, human resources development and education related to the world of work. The article is concluded by stressing the need for establishing firm linkages between educational and developmental infrastructures with special emphasis on nonformal education and its flexibility of approach.

Zusammenfassung Der Nachdruck in diesem Artikel liegt auf der Bedeutung, die der armutsbekämpfenden Orientierung ländlicher Entwicklungsprogramme beizumessen ist, sowie auf der Notwendigkeit festzustellen, welche Implikationen sich aus einer solchen Strategie für das Erziehungswesen ergeben. Einige für das Verständnis und die Formulierung seiner Rolle entscheidende Voraussetzungen, abgeleitet aus neueren Erfahrungen mit Entwicklungsprogrammen, insbesondere ländlichen, werden vorgestellt und analysiert. Die für die Bemessung armutsbekämpfender ländlicher Entwicklung benutzten Indikatoren bringen auch Klarheit in das Konzept einer konkreten Verbindung von Entwicklung und Erziehung. Dann bespricht der Autor einige Besonderheiten der Erziehung für ländliche Entwicklung und unterstreicht dabei die Wichtigkeit von vier Gebieten der Erziehungsarbeit: Primarerziehung, funktionelle Alphabetisierung, Entwicklung von Arbeitskräften und auf die Arbeitswelt bezogene Erziehung. Zum Schluß hebt der Verfasser die Notwendigkeit hervor, die Infrastrukturen für Erziehung und Entwicklung fest miteinander zu verbinden, mit besonderer Betonung der nicht-formalen Erziehung und ihrer Flexibilität.

Résumé L'auteur de cet article met en évidence la signification du développement rurale envisagé comme une lutte contre la pauvreté dans les pays en développement et il souligne la nécessité de découvrir les implications de l'éducation dans une telle stratégie. Il présente et analyse quelques-unes des inductions tirées de l'expérience contemporaine du développement, en particulier du développement rurale, indispensables à la compréhension et à la formulation du rôle de l'éducation. Les indicateurs utilisés pour mesurer le développement rural anti-pauvreté apportent aussi une clarté au principe de conjugaison de l'éducation et du développement en termes concrets. Ensuite l'auteur examine quelques traits de l'éducation pour le développement rural, mettant l'accent sur l'importance de quatre zones d'activités éducatives, à voir, l'enseignement primaire, l'alphabétisation fonctionnelle, le développement des ressources humaines et l'éducation reliée au monde du travail. Enfin il souligne la nécessité d'établir des liens solides entre les infrastructures de l'éducation et celles du développement, en accentuant particulièrement l'éducation non-formelle et la flexibilité de ces moyens.
