Our study approches, from a historical synchronic-diachronic perspective, ” The Practical Pedagogy”, published by Ștefan Bâsănescu in 1941, with the declared purpose to constitute the scientific art of thinking and supporting lessons. The theme’s importance is related to the fact that all the education from the primary school to the academic is obtained through the middle of the lessons, in which occur all kind of methods, forms, ways and organizing processes or all kind of didactic material, school furniture and school books. The lesson’s projection, thus, becomes a fundamental, theoretical and practical problem about: a) the component parts and elements; b) lessons’ types identified according to the objectives that aim communication, the creation of cultural values, included in school curricula; c) it structural aspects, dependent on the study objects and the educational degrees; d) general Didactics normativity, available to all study objects abd educational levels. Thus, Ștefan Bârsănescu elaborates a lesson model, reasoned by the praxiological dimension, of the culture’s philosophical pedagogy, promoted in the modern and contemporary history epoch.
