With the overall scientific and authorial work of educators and didacticians, a Greek pedagogical and educational science began to take shape.

With the establishment of the ASEP exams for prospective educators, there is a need for the pedagogical and didactic competence of the candidates, a competence that is modern and commensurate with the requirements of modern pedagogy and didactics that meet the needs of the times.

The results of the 1998 and 2000 exams, which preceded the establishment of the ASEP exams, proved the inadequate pedagogical and didactic training of the prospective educators. The required training can be achieved either in pedagogical departments or through self-education of the prospective educators by studying modern pedagogical and didactic textbooks that meet the requirements of the ASEP exams. However, such textbooks by specialized scientists in this field do not currently exist. In order to fill this gap and contribute to the modern didactic training of prospective educators, I proceed with the completion of this work, to meet the didactic requirements of the ASEP exams, as mentioned in the announcement.
