Annales Universitatis Paedagogicae Cracoviensis Studia Ad Didacticam Mathematicae Pertinentia VII (2015)
FOLIA 196 Annales Universitatis Paedagogicae Cracoviensis Studia ad Didacticam Mathematicae Pertinentia VII (2015) ISSN 2080-9751 Paolo Bussotti Leonardo Pisano called Fibonacci, between advanced mathematics, history of mathematics and mathematics education: three examples drawn from Liber Quadratorum∗ Abstract. In this research, three problems faced by Leonardo Pisano, cal- led Fibonacci, are dealt with. The main purpose is to show that history of mathematics can offer interesting material for mathematics education. The approach to the use of history of mathematics in mathematics education cannot be merely historical, but adapted to the needs of the explanations in a classroom. In the course of this paper, the meaning of such assertion will be clarified. A further purpose is a trying to explore the relations history of mathematics-mathematics education-advanced mathematics. Last, but not the least, a further aim is to offer a specific series of interesting material to the teacher in order to develop stimulating lessons. The material here ex- pounded is conceived for pupils frequenting the third and the fourth years of the high school, but, with minor modifications, it can be adapted to the fifth year of the high school and to the initial years of the scientific faculties at the university. 1. Introduction Federigo Enriques (1871-1946) claimed on several occasions there is not a clear distinction between advanced mathematical research, history of mathematics and mathematics education.1 Given the extreme specialization of advanced mathema- tics (which existed already in Enriques’ epoch) and since history of mathematics and mathematics education have also become specialized fields of research, Enri- ques’ assertion ought seem paradoxical or wrong, at all. -
Leonardo Fibonacci
Fibonacci Michael Stanfield The Life of Fibonacci The Italian mathematician Fibonacci was born as Leonard Pisano in 1170 A.D. His mathematical name, Fibonacci, is short for the Latin expression son of Bonacci. He was born in the city of Pisa and later passed away there about 80 years later. Even though Fibonacci is Italian, he received his education in North Africa after his father received a superior profession and moved the both of them there. The North African education he received is what led him to his primary contributions to the modern day mathematical subject. Guilielmo Bonacci, the father of Fibonacci, was a Holy Roman Empirical diplomat. In Pisa, Guilielmo was the representative of the merchants that resided and transacted there. This was an important profession during the time because this was a time period that the Italy was experiencing increasingly important and persistent sea trade. Although Pisa is not a sea port, a massive amount of traded goods still went through the town as it was close to the coast. When Fibonacci was young, his father became a consul to a North African port of Bugia, in present day Algeria, due to his work as a representative. He protected the Roman interest in the port of Bugia. After Fibonacci and his father moved to North Africa, Fibonacci received his education there. This is when and where he learned from Arab masters of mathematics. After learning from the Arab mathematicians, Fibonacci traveled around Northern Africa and Europe to Egypt, Syria, Greece, and other countries to study more about different systems and calculations. -
