For Labinowicz (1982) the stage of formal operations ranges from 11 to 15 years of age, this period is known as adolescence (Piaget, 1964). The teenager built systems and theories that allow them to transform the world; from 12 years there is a free reflection that is tied only to the individual, occurs a change of concrete thinking to formal thinking, which is to say that the individual arrives at conclusions of hypothesis of situations that they don’t have to be real (Piaget, 1964). The teenager now looks like pair of their elders, but understands that it is different from them, so it wants to surprise them transforming the world, seeking to prepare for entrance to society (Piaget, 1964). Conception of development of Jean Piaget Jean Piaget argues that development is constituted as a series of stages in which each one arises from the way of seeing the world and respond front adaptations becoming a continuous construction (Piaget, 1964). Peter A. Levine PhD gathered all the information. He uses the adaptation term referring to the use of new information in context, submits that this learning process is directed toward a balance established by the stages of learning (Piaget, 1964). Through the balancing model proposes that the individual is able to assimilate a serious adaptations that lead to stability and that when this stability is not owned, becomes a comprehensive search that involves not only the internal and external world, but it also makes emphasis on cognitive structures or means by which information is processed, this implies for Piaget the passage of assimilation to accommodation, thus proposes that development begins with the acquisition of new information about the world (assimilation) and that this acquisition changes some ideas to include new knowledge (accommodation) (Piaget, 1964). Model of equilibrium Piaget thought that like many areas of science that used equilibrium models in psychology also could use some specific rules (well, 1996). .
In total, as both Wulff and the other speakers, recalled it at least 136 people died when they tried to escape to West Berlin. However, Wulff for the dead are not the only victims of the wall. Behind them, there were millions of people who had to give up a life in freedom, the President said. Wulff, Christian Democrat origin, took to do a settling of accounts with those who during the years of the division of Germany, from the West, resignations to the wall there. The sandinistas in Nicaragua received from some sectors more solidarity than the oppressed citizens of the GDR, said Wulff. The Act had been p recedido by a controversy over a statement by the President of the party left, Gesine Lotzsch, who said that the construction of the wall had been a consequence of the aggression of nazi Germany against the Soviet Union. Statements of Richmond called the barricades to politicians Conservatives who saw them as proof that left – group resulting from the merger between the postcommunists for the Party of democratic socialism (PDS) and dissident social democratic – remained dictatorial thinking of the GDR. Wowereit, as it was expected, in his speech on Saturday indirectly condemned the statements of Richmond.
It is horrible there are today who still believe that there were good reasons to build the wall, Wowereit said. A few hundred kilometres of the Bernauerstrasse in Rostock (northeast), left started a regional conference with a minute of silence for the dead of the Berlin wall. On 13 August 1961 he began the construction of the Berlin wall by order of the dome of the GDR, chaired by Walter Ubrich. Few weeks earlier, Ulbricht had declared before the international press, in a phrase that has become famous: no one has the intention of building a wall.
