"The new education" means, in fact, developing the forecasting, simulation, design and evaluation skills of the human being in order to develop critical judgments, to improve its own decision-making capacity, to act in freedom and independence, to filter the information through a powerful creative attitude, in other words, the training of the human being into being creative. Critical thinking uses multiple cognitive functions to form the abstract, formal knowledge of reality. It allows the subject to picture a scientific view of life, a corresponding abstract image of the reality. The fruits of critical thinking lie not only in capability of overcoming obstacles from a scientific point of view, but it also provides adequate answers to everyday affairs. A didactic strategy based on active-participative methods that stimulate creativity and critical thinking produces positive and long term effects in terms of problem solving throughout life.
