宅間流妙矩集・遷式術を教育的視点で眺めて

概要

The Takuma School is a school in Osaka that produced Kamata Toshikiyo (the 3rd) and Matsuoka Yoshikazu (the 5th), who wrote one of the most important textbooks of the 19th century, the Complete book for arithmetic practice. It has been known that the style of expression in the Takuma school differs from that in the Seki school. In this paper, we discuss Takuma School’s Collection of exquisite formulate and Methods of transformation of equations written by Oka Shichibei Yukitada, who was a student of Matsuoka. In particular, we look at those collections from an educational point of view. After categorizing the problems listed, we found that about 90% of the problems in the volumes other than “Shikiki-jutu” were plane geometry problems. In addition, there are special solution methods, such as auxiliary lines and figure folding, which are rarely seen in modern times. Each volume has its own unique phrasing. Since “Shikiki-jutu” has features not found in the other five volumes, further study is needed to make it a six-volume set.
