This paper analyzes the role of abduction in proving process when students solve a geometrical problem. Solving a problem is like playing a game in which rules have to be defined. Two kinds of rules are considered: definitory rules that define the basic moves in the game and strategic rules that explain how to play the game. These two rules can be associated to two types of abductions that can be used to solve geometrical problems. The purpose of this paper is to compare these two abductions… 


How can the relationship between argumentation and proof be analysed?
The paper presents a characterisation about argumentation and proof in mathematics. On the basis of contemporary linguistic theories, the hypothesis that proof is a special case of argumentation is
Argumentation and algebraic proof
This paper concerns a study analysing cognitive continuities and distances between argumentation supporting a conjecture and its algebraic proof, when solving open problems involving properties of
The role of abduction in proving processes
This paper offers a typology of forms and uses of abduction that can be exploited to better analyze abduction in proving processes. Based on the work of Peirce and Eco, we describe different kinds of
Some difficulties with proof by contradiction seem to be overcome when students spontaneously produce indirect argumentation. In this paper, we explore this issue and discuss some differences between
Magnani’s Manipulative Abduction
Despite the extensive research in logic, cognitive science, artificial intelligence, semiotics, and philosophy of science, there is no sure proof that we have better or deeper understanding of
Abduction and the Emergence of Necessary Mathematical Knowledge
The prevailing epistemological perspective on school mathematical knowledge values the central role of induction and deduction in the development of necessary mathematical knowledge with a rather
Analysis of the cognitive unity or rupture between conjecture and proof when learning to prove on a grade 10 trigonometry course
We present results from a classroom-based intervention designed to help a class of grade 10 students (14–15 years old) learn proof while studying trigonometry in a dynamic geometry software
A method for revealing structures of argumentations in classroom proving processes
Proving processes in classrooms follow their own peculiar rationale. Reconstructing structures of argumentations in these processes reveals elements of this rationale. This article provides
