189) In this same line of thought, same authors Krulik and Reys (1997) affirm that to get success in the Resolution of Problems, the elaboration of strategies to be is important followed, in which they deal with 5 strategies that could very be taught well in the schools, that are: Attempt-and-error: it simply involves the application of the pertinent operations to the given information. Standards: it considers particular cases of the problem, generalizing itself from these cases, arrives it the solution. To decide a simpler problem: ' can involve the resolution of one; ' case particular' ' of a problem, or a temporary jib of a problem complicated for a summarized version more. To work in inverse direction: this strategy differs from the previous ones, for the fact to leave of the objective, or of what it must be proven, and not of the data. Simulation: frequently, the solution of a problem understands to prepare and to carry through an experiment, to collect given and to take a decision based on an analysis of the data. (KRULIK; REYS, 1997, P.
189, grifo ours) Through these strategies, the pupil will be felt much more safe when deciding a problem, in such a way that, will be able at certain moments to facilitate its understanding, helping to not only decide it to it problems of same line of difficulties as the much more complex problems. 2.3 The Mathematics in the school Using itself the beginning of that the mathematics occupies the place of disciplines that more the pupil in the school disapproves, since the initial series. Valley to stand out some expressions as form of used justification to explain such fact: ' ' the mathematics is difcil' ' or still ' ' the mathematics is for poucos' '. The case is that the pupil knows disciplines that it is important for its pertaining to school advance, therefore, without the approval in such substance it finishes not continuing for another series, and finishes using these commentaries to justify the decurrent failures with disciplines, in which for many times, being until acceptable for the pertaining to school community the reprovao in Mathematics for being a complex substance for several.
Learn to forget is a good step in getting new and useful learning, especially when we walked on the rocky road of ethics, values and norms of social coexistence. This is what experts call “unlearn” a term that the dictionary defines as “forget”. However, this short definition leaves out a fundamental fact: unlearn requires a conscious effort, as there is a weakness of memory but a voluntary act by which the individual achieves his memories removed obsolete knowledge, unnecessary or harmful. Henceforth we will refer to the need to eliminate the learning that today are harmful not only for the individual but to the environment in which it operates. Let us note that a good variety of anti-values are embedded in the collective unconscious mimicked in proverbs or sayings which teaching and no one questioned content. It is time to initiate the questioning, forgetting …
the effort to unlearn. The school and the family should be eradicated for example, beliefs as “a hair of the dog”, through which someone feels he was betrayed with authority to act similarly to who betrayed him in a typical invitation to the most despicable of vengeance, as if all the vengeance. Another common saying, candidate for deletion, is “making papaya, papaya departure.” The phrase has a dangerous content because it is an encouragement to take advantage of the weaknesses and omissions of others without considering the effects that this behavior can bring who acts and who, inadvertently or otherwise, incurred in the regrettable mistake of “giving papaya. ” Who takes the “papaya” or in some cases, “the papayazo” laughs and celebrates, while others suffer and, incidentally start looking the opportunity of revenge. The preceding sentences are not alone. At his side would have to write other like, “He who sins and prays ties,” which makes me pay me “,” San Juan is now the party going, “thief thief who steals a hundred years of forgiveness” “Things are not the owner but of those who needs, “the end justifies the means” (what a terrible Machiavellian principle, etc.). In our country we have the obligation to eradicate the belief that we can act in any way because “… we are in Colombia” (or Venezuela), as whether this was a pass to behave like cavemen.
Credit to others allows seller commits to the purchaser at the moment this has future payment, and thus avoid the possibility of that customer is spent that amount elsewhere at a later date. From there is that when the credit is used judiciously, involves a service of mutually beneficial marketing that retailers can offer to their clients.Delivery: Delivery service is sometimes simply a convenience. For example, the pizza delivery by many enterprises located just minutes from the place of delivery. In other cases, this service is a basic need; for example the delivery of a fridge. Sometimes delivery is included in the price; in other cases not. Regardless of the cost assuming the delivery to the buyer, it’s a service that causes a cost, not only in concept of employee time and transport costs associated with it, but also from the point of view of the installation and proper use, in relation to the warranty expressed or implied.Warranty and service: even when a company has not extended a guarantee currently expresses this type of this obligation imposed by law. A product must have a measurable quality and conform to the ordinary quality for which typically use that product. The seller also has an implied warranty that for goods sold for private use will be suitable for that purpose.
To ensure that products are functioning properly and that they are preparations if they do not, companies usually offer some kind of warranty and repair. The range of alternatives for the warranty and repair service varies from the simple replacement of the product to complex systems of repair services. This repair is usually done regularly at a service center that is owned by the manufacturer, in the case of small items. And directly from the housing of the user, when the products cannot be transported easily. Each of these alternatives gives to understand potential, financial commitments, control systems and different possibilities of consumer satisfaction.
