Abstract
The article analyses five necessary axiomatic criteria to build the didactics of a discipline. Didactics means both the presentation of the axiomatic criteria defining and analysing and making evidence of the normative frame of the instructive activity projected and realized thought discipline in accordance with each school stage. Then the article analyses the pedagogical principles, namely the categorical imperatives having an axiomatic value, necessary in the design of didactic or educational activities. They were identified in the model of the structure of education, being valuable in the conceiving of the teaching –– learning –– assessment activities. The principles become operational on any design level if they are supported by the axiomatic theory.
Key words: axiomatic discipline, pedagogical principles, teaching process
