This critical essay describes three contemporary discourses which threaten the essential principles of educational sciences to such a degree that it is possible to start talking about the end of educational sciences, albeit with a hint of exaggeration. The end of educational sciences is understood to herald a change in educational constants and their replacement with different elements. We understand discourse as a way of perception in a given fi eld at a given time which is mirrored both in language and in the framing of debates in the fi eld. We progressively analyse three discourses (evidence-based discourse, discourse of practical research and technological discourse) and describe in detail the individual concepts and thoughts from which the discourses stem. The essay concludes with a summary of infl uences of the described discourses and also with showing how the discourses can replace some educational concepts, if the fi eld is not consolidated.
