Traced back to French as didactique, in reference to Greek in didaktikós, an adjective that indicates the quality of knowing how to instruct, from the past participle didaktos, ‘taught’, with reference to the verb didaskein, for ‘to teach’, from the root in Indo-European *dens-, for ‘to learn’. Then, the -ic suffix intervenes, in the sense of ownership.
On the other hand, the title of ‘autodidact’ is appreciated in the French autodidacte from the Greek in autodídaktos, guided by the prefix autos-, to point out oneself, in tune with the possibility and interest to learn. Originally, education implied limited access to knowledge, which would take decades to become universal, noting that even today there is a gap in higher education due to the cost of learning.
Didactics has become an icon that represents a teacher’s ability to communicate knowledge to the student, for which techniques and methods are developed to stimulate participation and/or awaken interest. At the same time, beyond the efforts to incorporate teaching methods, there is a certain predisposition to do so, so that the didactic person is commonly pointed out, extending to any context.
