In the philosophy of the educational reform, it is estimated that a good teacher is not an actor who lights up the stage, but a director who plays the student. "When a teacher flaunts his knowledge, one can admire, say," Wow, what a great communicator! It is very good to be so. But ... this is not what we are asked. As teachers, our job is to help students develop knowledge,''. In short, a good teacher is one who makes learning happen. He/she knows how to choose and organize the essential knowledge as well as the necessary notions for the structuring of knowledge; A teacher knows how to choose and implement the pedagogical approaches and techniques; He/she adapts his/her approach according to the learners for whom he/she is responsible.
