教学质量是高等职业院校生存和发展的生命线,科学有效的教学质量监控体系是提高教学质量的重要保证。系部是学院组织教学活动的主体,是教学管理工作的基层组织,学院教学质量的提高很大程度上有赖于系部教学质量监控的质量;加强系部教学质量监控,建立和完善系部教学质量监控体系,对提高教学质量具有十分重要的意义。 相似文献

论知识管理在学校管理中的应用与策略 总被引:10,自引:0,他引:10
知识经济时代,新的教育改革浪潮使学校面临知识管理的挑战。20世纪末,知识管理理论的兴起及运用为学校知识管理提供了思考的方式与背景。学校知识管理真正的本质应当是对信息与人员的管理,其目的在于对教育知识的创新、生产、储存、转移和共享,使学校成为知识型的组织。基于知识管理理论,学校知识管理的策略包括明确责任、强化知识管理意识与能力;创造条件,促成外明知识的转化及吸收;建构共生和协同发展的管理生态,促成学校成员内隐知识的共享;促进学校同外部知识之间的互动与整合;将知识管理与学校的绩效结合起来。 相似文献

The writing skills of 286 children (157 female and 129 male) were studied by comparing name writing and letter writing scores
from preschool to kindergarten with letter and word reading scores over the same time period. Two rubrics for scoring writing
were compared to determine if scores based on multiple components (i.e., letter formation, orientation on the vertical axis,
left–right orientation, and correct letter sequencing) would better reflect differences in children’s writing knowledge in
preschool and kindergarten than rubrics composed of one component (i.e., letter formation only). While developmental changes
in writing scores were found, little additional information was provided by multiple component scoring rubrics compared to
the single component rubric. Letter writing scores were more strongly related to letter and word reading scores than name
writing scores but neither writing score was predictive of growth. Implications of the findings for intentional/systematic
writing instruction in preschool curricula are discussed. 相似文献

The aim of the present study was to determine the effect of post-exercise ingestion of a unique, high molecular weight glucose polymer solution, known to augment gastric emptying and post-exercise muscle glycogen re-synthesis, on performance during a subsequent bout of intense exercise. On three randomized visits, eight healthy men cycled to exhaustion at 73.0% (s = 1.3) maximal oxygen uptake (90 min, s = 15). Immediately after this, participants consumed a one-litre solution containing sugar-free flavoured water (control), 100 g of a low molecular weight glucose polymer or 100 g of a very high molecular weight glucose polymer, and rested on a bed for 2 h. After recovery, a 15-min time-trial was performed on a cycle ergometer, during which work output was determined. Post-exercise ingestion of the very high molecular weight glucose polymer solution resulted in faster and greater increases in blood glucose (P < 0.001) and serum insulin (P < 0.01) concentrations than the low molecular weight glucose polymer solution, and greater work output during the 15-min time-trial (164.1 kJ, s = 21.1) than both the sugar-free flavoured water (137.5 kJ, s = 24.2; P < 0.05) and the low molecular weight glucose polymer (149.4 kJ, s = 21.8; P < 0.05) solutions. These findings could be of practical importance for athletes wishing to optimize performance by facilitating rapid re-synthesis of the muscle glycogen store during recovery following prolonged sub-maximal exercise. 相似文献

盐酸维拉帕米对有氧训练大鼠心肌细胞钙离子的影响 总被引:1,自引:0,他引:1
目的:研究L-型钙通道阻滞剂盐酸维拉帕米练对有氧训练大鼠心肌细胞钙离子转运功能的影响,以探讨L-型钙通道在有氧训练诱导的大鼠心肌肥厚发生中的变化.方法:采用跑台训练方式,建立大鼠有氧运动模型,运用激光共聚焦方法观察急性分离的大鼠心肌细胞钙离子转运的特点.结果表明:与安静对照组相比,有氧训练组加入维拉帕米后,大鼠心肌细胞钙离子荧光强度发生显著变化(p<0.01);两组分别再加入异丙肾上腺素后,有氧训练组胞浆钙荧光强度的降低幅度显著高于安静对照组(P<0.01).表明维拉帕米可抑制有氧运动诱导的大鼠心肌细胞肥大,同时降低心肌细胞[Ca2 ]i,降低大鼠心肌细胞L-型钙通道的丰度和功能. 相似文献

The aim of this study was to monitor longitudinal changes in young people's submaximal oxygen uptake (VO2) responses during horizontal treadmill running at 8 km x h(-1). The 236 participants (118 boys, 118 girls) were aged 11.2+/-0.4 years (mean +/- s) at the onset of the study. Submaximal VO2, peak VO2 and anthropometry were recorded annually for three consecutive years. The data were analysed using multi-level regression modelling within a multiplicative, allometric framework. The initial model examined sex, age and maturity-related changes in submaximal VO2 relative to body mass as the sole anthropometric covariate. Our results demonstrate that the conventional ratio standard ml x kg(-1) x min(-1) does not adequately describe the true relationship between body mass and submaximal VO2 during this period of growth. The effects of maturity and age were non-significant, but girls consumed significantly less VO2 than boys running at 8 km x h(-1). In subsequent models, stature was shown to be a significant explanatory variable, but this effect became non-significant when the sum of two skinfolds was added. Thus, within this population, submaximal VO2 responses were explained predominantly by changes in body mass and skinfold thicknesses, with no additional maturity-related increments. When differences in body mass and skinfolds were controlled for, there was still a difference between the sexes in submaximal VO2, with girls becoming increasingly more economical with age. 相似文献
