别了,茫然

不知何时,脸上探头探脑地冒出几颗青春痘,毛茸茸的小胡子也从唇边钻出。我用双手郑重地端着镜子,细细端详,忽地发现自己已步入那令人向往的花季。  相似文献   

寓素质教育于物理教学中     

张兴玉  饶福安 《机械职业教育》1999,(1)

物理教学普遍存在着内容陈旧与现代科学技术发展不相适应的矛盾,存在着重知识轻能力,重应试轻素质的偏向,这是当前物理教学改革中亟待解决的问题。因此,应在物理教学中重视素质教育。 一、物理教学与思想素质培养 在物理教学中,通过简介伽利略的生平和科学事迹,说明他一生坚持科学真理,至死不为罗马教皇的淫威所屈服的精神。伽利略的自由落体运动实验和论断以及斜面实验和推理,推翻了古希腊哲学家亚里士多德提出并保持了两千多年之久的关于《重的物体比轻的物体落得快》和《力是维持物体运动的原因》两大错误观点。号召学生学习伽利略不盲目崇拜权威的精神及探索自然现象本质的科学态度。从而激发学生的兴趣,提高学习热情。使学生受到马克思主义观点和科学方法的潜移默化的教育。 当前学生思想上普遍存在爱国主义、社会主义观点淡薄,缺乏独立自主、艰苦奋斗的精神,且自卑感严重。在物  相似文献

圣诞节 Christmas 纪念和庆祝耶稣基督诞生的基督教节日.罗马教会354年规定每年的12月25日是耶稣基督诞生的纪念日.据说是为了和世俗的农神节相一致,一些人认为基督的诞生就如太阳的重生.现代的圣诞节已不仅仅是宗教节日,而且还是全世界流传最为广泛、庆祝最为隆重的世俗节日,从12月24日持续到来年的1月6日.  相似文献

Social Presence and Implications for Designing Online Learning Communities   总被引：2，自引：0，他引：2  

Charlotte N． Gunawardena 《开放教育研究》2005,11(5):54-60

With the rapid global proliferation of the Internet and telecommunication networks , online education , one form of distance education is currently becoming the fastest growing trend of domestic and international education. A major challenge to designing online learning is the development of appropriate means to facilitate the social environment that is critical for higher order learning in many disciplines. In many online learning designs, the majority of resources are channeled to web interface design and technology, while little or no resources are devoted to facilitating the teaching and learning process, the negotiation of meaning and the validation of knowledge among peers and instructors that depends on a conducive socio-cultural environment and adequate learner support.  相似文献   

Exploring the relationship between hope and burnout in competitive sport     

Gustafsson H  Hassmén P  Podlog L 《Journal of sports sciences》2010,28(14):1495-1504

Researchers have postulated that hope may be an important factor associated with burnout. Consistent with hope theory contentions, low-hope individuals may be susceptible to burnout because they are prone to experience goal blockage, frustration, and negative affect, all of which likely increase the risk of burnout. We examined the relationship between hope and athlete burnout among 178 competitive athletes (63 females and 115 males) aged 15-20 years. Hope was significantly and negatively correlated with all three burnout subscales: emotional/physical exhaustion, a reduced sense of accomplishment, and sport devaluation. Moreover, results of a multivariate analysis of variance showed that low-hope athletes scored significantly higher than medium- and high-hope athletes on all three burnout dimensions. Finally, results revealed that agency thinking was a significant predictor of all burnout dimensions. Frustration over unmet goals and a perceived lack of agency, a characteristic of low-hope athletes, might pose a risk factor in athlete burnout, whereas being able to maintain hope appears to be associated with health and well-being.  相似文献   

Training of perceptual-cognitive skills in offside decision making   总被引：1，自引：0，他引：1  

Catteeuw P  Gilis B  Jaspers A  Wagemans J  Helsen W 《运动与训练心理学杂志》2010,32(6):845-861

This study investigates the effect of two off-field training formats to improve offside decision making. One group trained with video simulations and another with computer animations. Feedback after every offside situation allowed assistant referees to compensate for the consequences of the flash-lag effect and to improve their decision-making accuracy. First, response accuracy improved and flag errors decreased for both training groups implying that training interventions with feedback taught assistant referees to better deal with the flash-lag effect. Second, the results demonstrated no effect of format, although assistant referees rated video simulations higher for fidelity than computer animations. This implies that a cognitive correction to a perceptual effect can be learned also when the format does not correspond closely with the original perceptual situation. Off-field offside decision-making training should be considered as part of training because it is a considerable help to gain more experience and to improve overall decision-making performance.  相似文献   

Dismantling boundaries in science and technology studies     

Dear P  Jasanoff S 《Isis; an international review devoted to the history of science and its cultural influences》2010,101(4):759-774

The boundaries between the history of science and science and technology studies (STS) can be misleadingly drawn, to the detriment of both fields. This essay stresses their commonalities and potential for valuable synergy. The evolution of the two fields has been characterized by lively interchange and boundary crossing, with leading scholars functioning easily on both sides of the past/present divide. Disciplines, it is argued, are best regarded as training grounds for asking particular kinds of questions, using particular clusters of methods. Viewed in this way, history of science and STS are notable for their shared approaches to disciplining. The essay concludes with a concrete example--regulatory science--showing how a topic such as this can be productively studied with methods that contradict any alleged disciplinary divide between historical and contemporary studies of science.  相似文献   

Protective Effect of Emblica officinalis Against Alcohol-Induced Hepatic Injury by Ameliorating Oxidative Stress in Rats     

Damodara Reddy V  Padmavathi P  Gopi S  Paramahamsa M  Varadacharyulu NCh 《Indian journal of clinical biochemistry : IJCB》2010,25(4):419-424

The effect of Emblica officinalis fruit extract (EFE) against alcohol-induced hepatic damage in rats was investigated in the present study. In vitro studies showed that EFE possesses antioxidant as well nitric oxide (NO) scavenging activity. In vivo administration of alcohol (5 g/kg b.wt/day) for 60 days resulted increased liver lipid peroxidation, protein carbonyls, nitrite plus nitrate levels. Alcohol administration also significantly lowers the activities of superoxide dismutase, catalase, glutathione peroxidase, glutathione S-transferase and reduced glutathione as compared with control rats. Administration of EFE (250 mg/kg body weight) to alcoholic rats significantly brought the plasma enzymes towards near normal level and also significantly reduced the levels of lipid peroxidation, protein carbonyls and restored the enzymic and non-enzymatic antioxidants level. This observation was supplemented by histopathological examination in liver. Our data indicate that the tannoid, flavonoid and NO scavenging compounds present in EFE may offer protection against free radical mediated oxidative stress in rat hepatocytes of animals with alcohol-induced liver injury.  相似文献
