The Dudley Challenges: virtual balloon journeys and real learning

The Dudley Challenges were developed to celebrate the millennium and the first year of the Dudley Grid for Learning. Three Challenges, Challenge 2000 the original resource, Challenge Europa and Junior Trek, are based on virtual balloon journeys, visiting a series of interesting cultural centres. Access to each centre visited is by solving a series of difficult, cross‐curricula problems that deliver a range of higher order learning experiences. Creativity, imagination, initiative, perseverance as well a range of ICT skills are promoted, developed and celebrated as key elements of the challenge.

Die Dudley Herausforderungen: Virtuelle Ballonreisen und wirkliches Lernen

Die Dudley Herausforderungen wurden zur Milleniumsfeier und zum ersten Jahrestag des “Dudley Grid of Learning” entwickelt. Die drei Herausforderungen, Challenge 2000 die Original Ressource; Herausforderung Europa und Junior Treck beruhen auf einer virtuellen Ballonreise, in deren Verlauf eine Serie interessanter kultureller Zentren besucht werden. Der Zugang zu jedem besuchten Zentrum ist nur nach Lösen einer Reihe schwieriger Allgemeinbildungsfragen, die einen hohen Lernzuwachs liefern, möglich. Kreativität, Einbildungskraft, Initiative, Durchhaltevermögen ebenso wie Computerkompetenz werden gefördert, entwickelt und gefeiert als Schlüsselelemente der Herausforderung.

Les Challenges Dudley :les voyages virtuels en ballon et l’apprentissage réel

Les Challenges Dudley ont été crées pour célébrer le millénaire et la première année de la Grille d’Apprentissage Dudley.Trois de ces Challenges, le Challenge 2000 la resource –mère,le Challenge Europa et Junior Trek sont fondés sur des voyages en ballon virtuels qui permettent la visite de centres culturels pleins d’intérêt.Pour accéder à chaque centre et le visiter , il faut résoudre une série de problèmes difficiles, interdisciplinaires qui offrent une gamme d’aventures apprenantes de premier ordre. On stimule,on développe et on célèbre ainsi la créativité, l’imagination,l’initiative la persévérance ainsi qu’un éventail de compétences en TIC qui sont les éléments‐clés du Challenge.     

Predictive ability of the medicine ball chest throw and vertical jump tests for determining muscular strength and power in adolescents

This study examined the predictive ability of the medicine ball chest throw and vertical jump for muscular strength and power in adolescents. One hundred and ninety adolescents participated in this study. Participants performed trials of the medicine ball chest throw and vertical jump, with vertical jump peak power calculated via an estimation equation. One-repetition maximum and peak power for the chest press and leg press were assessed using pneumatic exercise machines. The medicine ball chest throw strongly correlated with chest press one-repetition maximum and peak power, while the vertical jump peak power strongly correlated with leg press one-repetition maximum and peak power. The predictive ability of medicine ball chest throw was better than vertical jump peak power for muscular strength and power when controlling for sex, age, height, weight, and maturation, and was not affected by involvement in sports. Results show good predictive ability of the medicine ball chest throw for muscular strength and power in adolescents, while predictable ability of vertical jump peak power is weakened when other factors are taken into account.     

Physiological implications of preparing for a natural male bodybuilding competition

This study aimed to describe the body composition and physiological changes which take place during the in-season and recovery periods of a group of natural bodybuilders. Natural male bodybuilders (n?=?9) were assessed 16 (PRE16), 8 (PRE8), and 1 (PRE1) week(s) before, and 4 (POST4) weeks after a bodybuilding competition. Assessments included body composition, resting metabolic rate (RMR), serum hormones, and 7-day weighed food and training diaries. Change in parameters was assessed using repeated-measures analysis of variance. Dietary protein intake remained high throughout the study period (2.8–3.1?g?kg^?1?d^?1). Fat mass (FM) was significantly reduced from PRE16 to PRE1 (8.8?±?3.1 vs. 5.3?±?2.4?kg, P?.01). There was a small decrease in lean mass (LM) from PRE8 to PRE1 (71.8?±?9.1 vs. 70.9?±?9.1?kg, P?P?>?.05). Large reductions in total and free testosterone (16.4?±?4.4 vs. 10.1?±?3.6?nmol?L^?1, P?. 116.8?±?76.9?pmol?L^?1, P?. 19.9?±?7.6?nmol?L^?1, P?. 72.5?±?8.5?kg, P?. 25.4?±?9.3?nmol?L^?1, P?相似文献

商品包装设计中的文化美感对消费行为的影响

随着社会经济的发展,人们对商品的包装提出了更高的要求,提高商品包装的艺术美感,突出人文气息、提高商品的文化内涵成为现代包装设计面临的又一个重要课题。而要把握好商品包装设计审美中的文化内涵趋向,包装设计的材料美、色彩美、造型美则起着主导作用。对产品进行文化定位,对消费群体的文化心理进行全方位的了解,使产品外包装所表现的文化内涵与消费者产生知觉共鸣,才能促使消费者产生购买商品的欲望与行动,从而影响消费行为,通过包装达到启迪消费的功能。     

关于网络广告的欺骗性接触形式的思考

关注新近出现的欺骗性接触形式的网络广告,分析其性质及表现方式,并从广告主体利益、相关法律法规、网络监管等方面分析产生这种网络广告形式的原因,进而从道德伦理方面对欺骗性接触形式的网络广告进行思考。文章分析了网络广告形式的创新及其原则,并结合社会各界的反应,认为网络广告欺骗性接触形式的前景并不乐观,创新应符合社会的道德伦理规范。
