Hello. Despite a course learned by heart, DM scrupulously, sometimes private lessons already tempted, the level remains low see continues to fall? Matter does not interest anymore? The exercises are easy and yet the controls end badly? Well, it would seem that this is the case for many students who have a problem in common: Classical teachers do not have the means to ensure that the student is INTERESTED in the subject and REFLECTS how it works, but privileges the "by heart" Nothing more logical that when a problem becomes insoluble if it deviates slightly from the standard ....... Doing string exercises and reciting classes as a typical private teacher does is not the answer ..... My classes do not consist of doing DM for the grade, exercises for quantity, or reciting a class that should already be known in my speech. On the contrary, the course consists in imagining, explaining the origin of the studied property, its functioning, alternative methods. All this in order to have a more flexible mind, able to think and solve problems alone, with an increased interest in the subject, all in good humor, everyone knows how much it can be boring to have evening classes .... In short, the specificity of my courses is the desire to put the student in a good mood, to make him want to show him the possible applications of the courses studied. This is by demonstrations of use in trades, by crazy but funny assumptions, but it induces an involvement of the student. One of my former students lacked understanding when speaking of a problem and its solution, another of scientific interest leading to a quarter of an hour of scientific culture at the beginning of any course. Another still lacked encouragement. The learning problems are varied, find yours together! I have a purely logical operation and a bad memory, so it will be difficult for me to hammer something in the mind of someone who does not know how to do it myself ... hence a methodology and an atmosphere that should give desire. For example, anyone who knows how to draw a circle should find with a square and a protractor any value of trigonometry from any angle ... No need to learn by heart ... And that is even easy to head for easy angles ... The principle applies easily in math and physics. experimentation in English gives satisfactory results. For effective help, I count at least one course of two hours of suites a week. Engineer ITII Burgundy French in production management, resulting from a scientific training. Do you know why the sky is blue? How do you define a comparison in mathematics? Can we "draw" statistics? What is sound? Knowing how to answer these questions correctly is a huge leap forward.
