Lessons of Math, Physics, Chemistry, Autocad, Computer, English, Guitar – Barcelona.


PARTICULAR CLASS







    In the 3 rooms next to the windows of the walk, it will be taught private classes and English courses, separating the children and their companions of the older students, in appropriately reduced groups to get the personal attention required.

    In this center we consider that if the books and audio-visual material are correctly developed, the classes with a professor dedicated to writing notes on a blackboard are a waste of time. In addition, it usually happens that, the teachers of public centers, after obtaining their degree it goes directly to the classrooms, without requiring experience in the real world, with which they can hardly differentiate the useful from the useless. In addition, the exercises that appear in the exams are copied from the books of solved problems that the publishing houses facilitate to the educational centers, discarding solutions with hypotheses of work different from those supposed in these books.

     To justify the current system of education as nurseries, it taught at  a level and it examine at a slightly higher level. Examples:

     Children are forced to memorize the multiplication table, without explaining that it can be obtained from a Cartesian table by adding values, and that thanks to the commutative property, it is only necessary to memorize half.

      Spelling is taught dictating stale literary texts, rather than searching for lists and mnemonic phrases that group words that contain phonetically conflicting characters such as h, v, g, and accents in plain words.

     They teach the rules of algebra and the way to check the result of a system of equations, but without explaining that there are systems of indeterminate equations that have no solution because some of the equations is repeated or is in contradiction with the rest .

    It is taught to solve fractions with integer values, without explaining the general method suitable for real values ??in general. Or,  it is given a formula to add fractions, instead of explaining that multiplying each fraction by the fraction required to obtain a common denominator, and taking common factor, it is not necessary to memorize anything. Thus, for example, it is given the formula  to add two resistors in parallel, without explaining the general casein which we have more than two resistors.

    It is taught the rule of three, instead of using conversion factor,that is, simply multiplying and dividing the 3 data so that their units are simplified, without memorizing anything.   It is taught to raise problems of trigonometry, without explaining that, in many cases you can only clear variables in one direction,having to solve by trial and error the other cases. This problem is evident in Electronics.

    In resolution of limits, it is necessary to carry out difficult steps that are difficult to guess at the time of examination, without explaining that, even in trigonometric expressions, the limit can be found by substituting the variables of the function for the value under study. For example, substituting pi / 2 for 3.1416 / 2.

    In integral calculus,  there are applied elaborate substitutions of variables difficult to guess in time of examination, without explaining that, in fact, all function is derivable, but it can not always integrate a function to obtain its derivative.

    In Temodynamics, the problems usually lack some data, which depends on a working hypothesis, which requires to assume that some parameter remains constant. That is, it is about guessing the working hypothesis used in the book of solved problems, especially when abstract parameters such as Entropy are involved that depend on experimental tables, not available for all compounds and possible mixtures.

   In short, it is advisable to go one step ahead of the teacher to avoid the traps that may contain the exams.






    As for computing, after Windows XP, with the change of hardware from32bit to 64bit, the customized programs developed with Visual Basic, used by the majority of technicians for Management, Planning and Engineering, stopped working. Theoretically it is possible to develop these programs again with the Visual Studio application, but in reality there are installation problems. In addition, the Windows Defender program of Windows 7 and Windows 10, which is mandatory and reactivates itself, deletes without asking for files of applications according to criteria that are not at all clear.


    Despite these difficulties, reinstalling programs whenever needed, itis possible to provide training courses for the essential programs of office automation and computer-aided design in 2D and 3D.
