Hello, I am a teacher of mathematics in high school for 20 years.I give courses in all sections, especially in S.I am in charge of math specialties. S in my school for 5 years. I am an associate of mathematics and holds a DEA in geometry and modeling analysis. So I have a great pedagogical experience and a strong mathematical and scientific culture: method, techniques, history, applications in physics, economics, arts and many other fields. I base myself on the student's notebook. First, make sure the course is taken correctly, and if not, fix it. At least 50% of the work is done through sustained listening and careful note taking of the current student. To consolidate learning, it is imperative to re-read the course, the same day if possible. Learning and understanding of the course are the first steps to success. Once the course reviewed, possibly re-explained, we must redo the typical exercises related to each chapter studied, which are very traditional. Afterwards, to go further, we can tackle more open problems. At the level of the final class, I propose a regular work on subjects of bac to develop the techniques and reflexes necessary to a great success the day of the test. We will also work on the reading of statements, possibly the management of stress during the tests. The method and themes will depend on the needs, abilities, desires of the student.
