The Didactics in Felix Klein's "Elementary Mathematics from a Higher Standpoint"

In the early 20th century, a demand arose for a course of university studies considering the special needs of future teachers. One of the well-known representatives of this movement is Felix Klein. Inter alia, he held lectures in Elementary mathematics from a Higher Standpoint. In the work at hand, I will present results of my Ph.D. theses, in which the lecture's manuscripts are analyzed concerning the underlying intention and inner structure. The article focuses on the didactical perspective, that among other characteristics specifies Klein's understanding of an advanced standpoint. The comparison with modern concepts of mathematics didactics may give an indication for a provound validation and possible adaption of Klein's concept.
