Motor Development

To this respect Mendes and N3obrega (2004) they affirm that: The human body, to the being compared with a hydraulical machine, receives an education considers that it only in its mechanical aspect, without proper will, desires and the recognition of the scienter of the human movement, which is explained through the mere reaction the external stimulatons, without any relation with the subjectivity. The thought of Discardings, established in the exercise of the control and the domain of the nature, influences the education through the rationalization of practical the corporal ones. (2004, P. 125) In century XVII AND XIX the idea of the desvinculao between body and the mind, make to thus appear a new paradigm in the education, the science of the motricidade human being, leading some thinkers to be argued importance of the motor development in the education. In this way the motricidade it human being is the quality to think and to act its desires in accordance with thus developing intelligence what it differentiates in them of the other animals. Thus the other animals have only the motricidade: Of the act to the thought and the gesture the word, the human being endowed with new psychic processes of information between the body and the brain acquired the position bpede, freed the hands to manufacture tools, emancipated the mouth and the face to finally communicate feelings and thoughts with its fellow creatures and, invented the symbol to make history, to transmit culture and to produce art and science. (FONSECA, 2010, P. 8) For Fonseca (2010), it is by means of the motricidade that we can we interact with the object and from this moment, to create tools for our use.

Barcelona Spain

The strike has generated shortages and the generalized madness of the Spaniards who have begun to collect food. In the website of the BBC in Spanish you could read the following about the situation of shortages which crosses Spain: we went to buy at the supermarket and there was nothing fresh. All the shelves of meat were completely empty. There was little fruit and no dairy products, like yogurt or milk people are buying much more where there will be shortages. Zapatero suggested him to truckers sector a series of thirty measures to alleviate the situation of the Guild, given steady increases in fuels, proposal which was rejected since the sector seeks the adoption of minimum of transport services rates so that they can move fuels increases to the cost of transport services. But that the situation in Spain is more complex than a conflict by the increase in the price of fuels. In the Financial Times, Leslie Crawford ensures that the prosperous and dynamic stage of the recent years has come to an end.

It is that after the construction boom, the crisis that is going through the Spanish real estate sector is very hard hitting the economy. Leslie Crawford takes the data from a study conducted by the University of Barcelona, which indicates the existence of more than one million of unsold homes which will require a time of more than two years for its liquidation, situation that indicates a little favourable prospects for the sector in the coming years. Faced with the economic slowdown and an increase in inflationary pressures, the Spanish Government has no monetary policy as an instrument to act faced with this situation, and must act quickly if you do not want that situation becomes increasingly worse. On Wednesday, Zapatero promised to meet with trade unions and employers to discuss the current economic crisis is affecting Spain. A new agreement from La Moncloa in Spain? It seems that the economic situation It is requiring of the union of all sectors to cope with the crisis situation. Spain already has a successful experience and is prepared to repeat it again will be willing all sectors to cede, in the pursuit of achieving recover the Spanish economy?

The Development

Consideraes final the affectivity and its motivador paper in the development of the learning We can thus stand out that the emotions constitute the main way I stimulate for it and the search of new forms of learning, that is, the search for knowing something is established from the moment that the individual attributes one meaning to such object, or conception, as it affirms Davis (2008): The emotions are gifts when it searchs to know, when it establishes relations with physical objects, conceptions or other individuals. Affection and cognition constitute non-separable aspects, gifts in any activity, even so in changeable ratios. The affectivity and intelligence if structuralize in the actions and for the actions of the individuals (p.83). Therefore, the paper of the professor goes beyond the transmission of the contents, it must know to mediate to the emotions that permeiam the relations in classroom, so that in this way it motivates this pupil the acquisition of the knowledge. Oliveira 2008, affirms that: One of the works most important to be developed for the professor next to its pupils is, therefore, to motivate them. It is not treated, here, to only stimulate them with compliments to the performance. In contrast, the good professor looks for to make with that the learning process is motivador in itself exactly: the children must be taken to place all its energy to face the intellectual challenge that the school places to them. The pleasure comes, thus, of the proper learning, the feeling of personal ability, the security of being skillful to decide problems (p.85). It fits then, the school to provide to its pupils a motivador environment, becoming process of the productive and significant learning, way that this student can feel itself motivated to frequent the half pertaining to school, and to search new knowledge throughout its development stimulating its autonomy. In this way, the act to study becomes not as an obligation, but as something pleasant.
