From there we have that the specific subjects of the philosophy, not obstante its history, not importing its largeness and magnitude, if will not have to see with the pupil and its life, it will be rejected fixedly, always. Let us say, for example, if she was disciplines it of Portuguese Language the presented liame to make the linking of disciplines studied in room with the life of the pupil is that it needs this every day, to communicate themselves verbally, to write or same to read a statement of any another one disciplines is necessary to know the grammatical rules, syntactic, semantics; then, the Portuguese Language is substantial part of the daily one of the pupil, then this disciplines must be white of interest redoubled on the part of them in the classroom. Duty to be, does not mean, of form some, that effectively either. How to attract the attention of the pupils for disciplines of Mathematics? Simple. It is part of the life, not if she can cross the street without it. When it is looked at for the side and it waits the car to pass stops later crossing the street uses Mathematical it. Calculation of speed and displacement importantssimo for the subsistence, of the opposite, without this calculation the life would be permanently at risk of being run over. In the daily drudgery the Mathematics is necessary in the purchases of supermarket, in the traffic light, among others and therefore the pupils if they interest for disciplines in bonanza way. also therefore that it disciplines it account, in the majority of schools, with four weekly lessons. What I tried to demonstrate above was a reasonable justification offered by the professors of the respective ones disciplines so that the pupils if interest for the content displayed in classroom, is good the justifications, without a doubt, but of the expectation of the professor to the interest of the pupil it has an enormous irrigation ditch, almost unsurmountable.
