整体感知有效掌握生字——二会生字的教学方法

新教材增大了识字量,目的是为了让学生提早阅读,大量阅读,为提高表达能力打下基础.目前,部分教师由于不清楚要求认读生字的教法,用教四会字的方法教二会字,费时多,识字效率又不高.为此,可采用整体感知的识字方法.具体的方法和途径是:1.创设情景,激发兴趣:①创设生活的情景.②创设游戏的情景.③创设即时评价的情景;2.即时评价,强化记忆;3.及时复习,克服遗忘.每单元开展"我是五星级识字小能手"的活动;4.课后阅读,促进巩固.     

微分分光光度法的原理及应用

一、概况在分光光度分析中,当被测组分和共存组分的吸收峰发生重叠时,常进行下列预处理.1.将干扰组份分离.2.应用化学反应,使两组份的吸收峰产生偏移.3.使用掩蔽剂将干扰组份掩蔽.4.从若干个吸收峰和浓度的关系出发,建立数个联立方程,然后解此联立方程.     

技艺需要与政治——自由和平等关系的疏朗

人类是通过技艺满足需要的动物.由于需要之间、技艺之间的冲突,人也是政治动物.技艺在近现代取得了快速的发展.在政治上,人类产生了对自由和平等的要求.自由和平等是冲突的,不过二者都根植于人的需要和技艺.因此对自由和平等的思考应该深入到这个层次.现代社会的基本特征是,人的需要以获利为形式得到极大的张扬,政治领域和经济领域被分离.这个事实值得警惕和反思.毕竟,人既是生产动物,也是政治动物.

Helping in 36 U.S. cities.

A series of experiments examined the relationship of urbanism to helping. Six types of helping behaviors were studied in a cross-sample of 36 small, medium, and large cities across the United States. The relationship of helping to a series of statistics reflecting the demographic, social, environmental, and economic characteristics of these communities was then examined. The strongest and most consistent predictor of overall helping was population density. There were significant correlations between economic indicators and helping in 3 situations. Helping in some situations also tended to be negatively related to violent crime rates and to environmental problems. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

R.A.P.I.D. Reconstructive alternative for prosthetics in implant dentistry

As stated at the outset, this technique is not for every case. Each case must be selected with great care, consideration and careful planning. In concert with observing the Implant Lighthouses, this technique can produce a successful case. It can be done to save time, without compromising the prescribed techniques and quality.     

Dislocation dissociation in some f.c.c. metals

The dissociation of a perfect screw dislocation into a stacking fault in an f.c.c. lattice is modeled by the modified lattice statics. The interatomic potentials are obtained from the work of Esterling and Swaroop and differ substantially from those empirical potentials usually employed in defect simulations. The calculated stacking fault widths for aluminum, copper, and silver are in good agreement with weak beam microscopy results.     

Master resilience training in the U.S. Army.

The U.S. Army Master Resilience Trainer (MRT) course, which provides face-to-face resilience training, is one of the foundational pillars of the Comprehensive Soldier Fitness program. The 10-day MRT course is the foundation for training resilience skills to sergeants and for teaching sergeants how to teach these skills to their soldiers. The curriculum is based on materials developed by the University of Pennsylvania, the Penn Resilience Program (PRP), and other empirically validated work in the field of positive psychology. This “train the trainer model” is the main vehicle for the dissemination of MRT concepts to the entire force. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

X-Ray-induced translocations in spermatoginia. II. Fractionation in mice

A patient with Alzheimer's disease, who is still alive, was investigated using a battery of tests, including design-copying and identification, the Gottschaldt hidden figures, a reading test, picture identification, and identification of tachistoscopically presented figures. The main observations were (i) an inability to handle more than one "element" of visual input simultaneously, (ii) an inability to attain and sustain a correct test performance. This last feature was assumed to be related to a difficulty in establishing and sustaining a set or attitude about how to solve the task. The hypothesis was put forward that both behavioral characteristics were related to a deficient task-related arousal-increasing mechanism.
