(Leicester) 27, No. 4, 48-51 (1998).} \itemab One of the problems in classroom life is the phenomenon that we can term the `fragmentation of knowledge', due to the fact that school subjects are taught separately from each other so that the result is islands in the learning process. In particular, mathematics, which is difficult for many pupils, suffers from this situation and, more than other subjects, is considered to be separated from the cultural context. History of mathematics is a key element in going across disciplines. \itemrv{~} \itemcc{A30} \itemut{} \itemli{} \end
