Certainly, didactic exposition is still important, it is a way of teaching, but it must be complemented with practical problem solving in the cases that can be applied, so as not to saturate the student with information but to allow him to relate it to its applicability in the real world. I think it is the task of a good teacher to detect the needs of his students and adopt the form of teaching that best suits his group, instead of choosing the same method for all, certainly his influence as a mentor is decisive in the process. Thanks for sharing your vision my friend!
