Podręczniki do matematyki Stefana Banacha w kontekście doświadczeń szkolnych autora

The aim of this paper is to analyse the content of school textbooks whose author or co-author was Stefan Banach (1892–1945), with particular attention paid to the scope of exploring equations, the method of introducing geometry to school teaching (whether to start it with discussing the basic planimetric concepts or basic stereometric concepts, or discussing them both parallelly?) and the range of political arithmetic (currently called financial arithmetic) problems. The paper examines the extent to which Banach’s textbooks were innovative in this respect. The research is based on, among others, the textbooks used by Banach as a secondary school student and the ordinances of the Polish ministry of education (Ministry of Religious Affairs and Public Education) from 1922.
