Being a student in artificial intelligence engineering (Master 2), I aim through the courses to make the students understand their courses and to practice on them, but also to answer their questions concerning their applications, because generally the students are asks a lot, why do we need to know this or that course?, where can I use it?, why does it interest me?, understanding with application perspectives will stimulate their enthusiasm for understanding mathematics, and it will help a lot in understanding the most complex lessons, something I have tried with quite a few students and which gives very good results, without losing the objective of explaining their lessons to them and guiding them towards autonomy in understanding.
