Holding a master's degree in civil engineering physics with high distinction, I offer mathematics, physics and chemistry lessons for secondary school students. Beyond the transmission of knowledge, I attach particular importance to the development of critical thinking in students. My goal is to lead students to ask the right questions: What does a calculation mean? What is its purpose? Why do we use this method? What is the objective behind an exercise? This approach allows us to move beyond purely mechanical learning towards a deeper and more lasting understanding. I also encourage students to develop their critical thinking skills regarding the methods used: Is the answer consistent? Is the chosen method relevant? Why perform this calculation rather than another? The goal is to teach them to understand what they are doing. Thanks to my academic background, I have encountered numerous situations where mathematics and science are used to solve real-world problems. This allows me to explain to students the purpose of science courses, showing them the actual use of the concepts studied and how they apply in concrete contexts. My teaching method also relies on learning through practice: exercises are central to the learning process. They allow students to solidify concepts, develop good reflexes, and learn to structure their thinking when faced with a problem. I guide the student through this process by helping them analyze, understand, and solve exercises progressively and independently. I therefore seek to transmit a genuine working method: analyze a problem, structure it, translate it into mathematical language, solve it logically and efficiently, and above all develop autonomous and critical thinking in the face of the problems encountered.
