Luca Pacioli was a Franciscan friar, a prolific writer, a devoted teacher, a mathematician and a close friend of Leonardo da Vinci. He is also known to be the"father of accounting". He is best remembered for his two books on mathematics: "Summa de Arithmetica Geometria Proportioni et Proportionalita" and "De divina proportione". These two books, which were printed in the field of mathematics for the first time by using Gutenberg's printing technology, contributed to the development of mathematics in Europe. In this paper, we investigate various aspects of his life and mathematical contribution of Pacioli based on these two books.

Gougu Rule for the right triangles is the Chinese Pythagorean theorem. In the late age of the Chosun Dynasty, mathematicians of Chosun pioneered the study of the Chinese Nine Chapters and other advanced mathematical problems as well as the Easternism in spite of the various difficulties after the Imchinoeran(임진왜란), Chungyuchairan(정유재란) and Byungchahoran(병자호란) The technologies of the addition and addition twice are the methods of the solution of the problems in the right triangles. This paper is intended to introduce some problems using these methods of solution.

In this paper, we developed a Web application program that could show the shape, the number of the vertices, the edges, the faces and development figures of polygons(regular tetrahedron, regular hexahedron, etc). The program was implemented using GSP(Geometer's SketchPad) and then converted to JAVA to display the results of GSP on the Web. The results of this paper are applicable to geometry of a junior high school course.

18세기 초 중인(中人) 홍정하(洪正夏)($1684{\sim}?$)의 구일집(九一集)과 양반(兩班) 조태구(趙泰耉)($1660{\sim}1723$)의 주서관견(籌書管見)에 들어 있는 구고술(句股術)을 조사한다. 구조적 접근과 천원술(天元術)을 통하여 홍정하(洪正夏)는 동양(東洋)에서 가장 앞선 구고술(句股術)의 결과를 얻어내었다. 또 17세기 중엽에 서양(西洋) 수학(數學)이 조선(朝鮮)에 유입된 후 조선(朝鮮) 산학(算學)에 이론적 접근이 이루어지는 과정을 조태구(趙泰耉)의 구고술(句股術)을 통하여 연구한다.

This paper explains methods of numerical analysis which appear on Cardano's Ars Magna and Newton's Principia. Cardano's method is secant method, but its actual al]plication is severely limited by technical difficulties. Newton's method is what nowadays called Newton-Raphson's method. But mysteriously, Newton's explanation had been forgotten for two hundred years, until Adams rediscovered it. Newton had even explained finding the root using the second degree Taylor's polynomial, which shows Newton's greatness.

본 논문은 CAS 계산기를 사용한 학습을 하고난 후의 고등학교 수학학습부진아 중 남녀 학생의 수학학업성취도에 차이가 있는지를 살펴보았다. 이를 위해 수학학습부진아를 선정하여 두 집단으로 나누었다. 한 집단은 처치집단으로 지필과 CAS 계산기를 사용하여 활동지를 학습하고, 다른 집단은 통제집단으로 지필만을 사용하여 활동지를 학습하였다. 이러한 학습의 전과 후에 지필평가를 실시하였다. 각 집단 학생들의 수학학업성취도를 살펴본 결과, 통제집단의 남학생과 여학생의 수학학업성취도가 유의미한 차이가 없는 것처럼, 처치집단의 남학생과 여학생의 수학학업성취도에서도 차이가 없었다. 처치집단의 남학생과 통제집단의 남학생의 수학학업성취도 비교와 처치집단의 여학생과 통제집단의 여학생의 수학학업성취도 비교에서는 모두 처치집단의 학생들이 더 높은 성취를 이루었다.

This paper demonstrates how a nineteenth century Japanese votive temple problem known as sangaku from Okayama prefecture can be solved using traditional mathematical methods of the Japanese Edo (1603-1868 CE). We compare a modern solution to a sangaku problem from Sacred Geometry: Japanese Temple Problems of Tony Rothman and Hidetoshi Fukagawa with a traditional solution of ${\bar{O}}hara$ Toshiaki (?-1828). Our investigation into the solution of ${\bar{O}}hara$ provides an example of traditional Edo period mathematics using the tenzan jutsu symbolic manipulation method, as well as producing new insights regarding the contextual nature of the rules of this technique.

In spite of important researches and translational works of the Joseon mathematical treatises in the 80's and on, these results were almost out of reach to the school teachers as well as students due to the antiquity of their contents and the terms used. In order to make our traditional mathematics approachable to the middle and high school students, it will be educationally meaningful to reinterpret them tuned at the student's level using modern terminology and symbols. In this study, we reinterpreted 9 problems from Cheukryang Dohae, which is one of the representative mathematical books of Joseon Dynasty. We used the terminology and symbols from the school curriculum. We also reconstructed two of them using modern metrologies adapted to modern situations adding illustrations and photos, so that they are useful at the teaching site.

This study expects that Team Based Project Learning can act positive role to improve pre-service elementary teachers' teaching competence from previous studies. So designing and executing Team Based Project Learning program, I can provide some suggestions to the teaching method for teacher training education. In this study, Team Based Project Learning focuses on the use of history of mathematics in school mathematics. Also from organizing the team to evaluation, I conduct team activity systematically both inside and outside the classroom. The result of this study shows that pre-service elementary teachers' teaching competence has improved and I could identify the positive response about the value of using the history of mathematics and effect of Team Based Project Learning in mathematics learning.
